Premium Performance Insulation With an R-value of 16 on two inches, Kingspan Kooltherm® premium performance rigid insulation has a higher R-value than any commonly used insulation. The width of external walls incorporating Kooltherm insulation is thinner than comparative solutions – facilitating internal space gains without increasing the overall designed footprint of a building.

Kooltherm’s higher R-value provides thinner insulation solutions. A thinner insulation can result in thinner external wall construction. A thinner external wall construction can result in greater internal floor area. A greater internal floor area can result in a greater Return on Investment (ROI).

Overcoming ‘Brutti’ Boxes and Cultural Restraints I’ve got a little “Rhymin’ Simon,” as in Paul, on my mind, as the opening line of “Still Crazy, After All these Years” keeps popping up: “I met my old lover on the street last night…” It wasn’t a literal case of connecting with a former paramour, but rather that I found myself in my old stomping grounds in Northwest Indiana—the locale of the first newspaper I worked at out of college in the ’80s. At the time, my beat covered a collection of small towns that were starting to feel the creep of Chicago, as more unsatisfied citizens made the exodus to the “country.”

Yet more than a quarter century later, heading down Highway 41, I felt a lot less nostalgic than the ruminating Simon, and more like the tearful native American observer in that ’70s PSA, choked up about the pollution and garbage fouling this once pristine land. In this instance, it was garbage of another sort that made me sad—the homogeneity of it all; the sad state of the built environment that everything, everywhere, looks alike—the same strip malls, chains, restaurants and big boxes populating Everywhere, USA. I was hit with more of this “vu ja de,” as Robin Williams once joked, on the grounds of the community college my boys attended. Specifically, while waiting to meet a colleague, I found myself back in the library’s periodical section browsing international architectural publications. In flipping through “Domus,” an Italian publication, I came across a story by a critic named Christian Burklein, who wrote a story “Ugly Boxes Everywhere”—It seems the phenomenon affecting once-rural America, is not exclusive. In Burklein’s story, he notes one Italian grocer, Bernardo Caprotti, has managed to find a way not to build ugly boxes. “I don’t think making lovely things costs much more than making ugly ones. It just takes a touch of elegance, and someone who is good with a pencil.”

If only there were more such enlightened souls…

Alas, another of the author’s comments—the fact that these “brutti” (ugly) buildings are often proposed and built without an architect—because in the eyes of local planners, they’re “unassuming civil constructions”—means, too often, we’re left with communities that offer little inspiration, and establish little, if no distinction, from one another.

That said, I’m proud, this issue, to reveal an example of a break in this chain, with the spotlight shining on Silver Spring, Md., and United Therapeutics’ “Unisphere,” project, our function feature. “Unabashedly innovative,” notes reporter Vilma Barr, who describes it as the product of the shared inputs from a dedicated team of designers, and a company driven to create, not only a visually striking building, but a net-zero structure in the heart of a dense, urban

core. In fact, Vilma points out the company’s decision makers rejected the concept of a greenfield office park, as it would have no positive effect on uplifting its surroundings.

It seems there are enlightened souls out there; the trick is finding them… Speaking of breaking chains, this issue will also break some norms within the realm of our own publishing experience, in that we’re going to be introducing a healthy dose of net zero content beyond the aforementioned feature. For those of you who haven’t seen Disney’s “Christopher Robin,” which is set in post-WWII London, [SPOILERS] a critical moment occurs in the film when the protagonist, preparing for an important presentation, loses his papers to the wind after a mishap. Yet amid this misfortune, hope arises when one of the pages lands upside down, and inspires a new perspective.

The Prodgial page featured a triangular graph breaking down the company’s sales. The bulk of which, for this fictional high-end luggage company, was only to a small segment—the well off. But when C-Rob looked at the inverted pyramid, he saw the opportunity for big sales by marketing a more affordable product to the larger community to “go on holiday.”

Because market forces are necessitating that we look at things differently, we are also changing things up, including the audiences that receive content from our other publications. Notably, we’re embedding content that would appear in our sister publication, Net Zero Buildings, here. With 2030 rapidly approaching, the time to act is now, as we feel this message needs to be communicated to the more mainstream in the AEC community, than those who have already converted to the world of high-performance design. Here’s to thinking outside the box.

Best Practices in Water Conservation ›› Management Plans

Priority One: Developing a Water Management Plan In the past, a sound water management plan may not have been a high priority for building owners.

Not any longer. There is increasing attention on the need to improve water management, whether to increase resiliency or address water shortages caused by drought, or simply to respond to the rising cost of water and sewer rates. In fact, according to a new white paper entitled “The Global Value of Water,” published by Global Water Intelligence, in partnership with Arup, the paper—which features world-wide analysis and commentaries on The Global Water Tariff Survey—notes the global average price of water and wastewater rose by 3.8% to $2.04—only held down by price cuts in Northern Europe and cities in Africa and the Middle East choosing not to increase rates. In some extreme cases, such as in Cape Town, South Africa, the city experienced a 390% increase in the benchmark price of water and wastewater services.

Commitment from the top has to be in place, so it’s clear that this is a top priority of the building owner or manager.

Keep in mind, in most cases, a building pays for water use twice, as many sewer charges are based on the water supplied to the building. So what to do?

The EPA has a pretty good idea. According to Lee Forsgren, deputy administrator for EPA’s Office of Water, do the following: 1) Commit. Put a team in place to develop and implement a water management plan. The commitment, says Forsgren, has to be made at a high level so it is clear that it is a priority of the owner or property manager. “The team should include people from across the organization including the facility manager who understands the building’s mechanical systems and basic infrastructure, staff responsible for regulatory compliance, and staff responsible for overseeing cleaning.”

2) Create an Assessment. Carry out a comprehensive assessment of facility water use. The only way to know exactly how a building uses water and where it consumes the most, notes Forsgren, is to conduct a water assessment and develop a water balance. “This will also help identify potential efficiency projects and prioritize efforts. This begins with collecting the billing data for at least the most recent two years to help set a baseline for assessing

progress,” says Forsgren, adding it’s also necessary to inventory the major water-using fixtures. “Consider the need for additional flow meters for larger systems to better manage water use. Don’t forget to assess outdoor water use.”

3) Develop an Action Plan. Create a plan that identifies specific projects and prioritizes them for action.

“Use the information from the assessment to determine where there are opportunities for significant water savings and, if associated with hot water, energy savings,” says Forsgren. “Some projects may only require changes to standard operating procedures, but some may need new equipment,” adding a good plan also identifies how projects can be funded. “Can activities be funded using operating expenses or will they require capital financing?

Buildings that use energy service companies may find that they are also able to carry out water efficiency projects through the contracts.”

4) Track Progress and Share the Information.

Review any meter readings and water bills, says Forsgren, to confirm that expected water savings are being achieved. “Sharing the results is also important because it builds accountability, helps to recognize success, or identify areas for improvement.”

Beyond saving money, for buildings in areas subject to drought, says Forsgren, having a plan to manage water use will improve resiliency to shortages. Elsewhere, Forsgren notes corporate

social responsibility is also a focus for a growing number of companies. “Demonstrating that they are addressing water use helps to demonstrate that the owner is a good steward. Some cities that have mandatory energy reporting and disclosure for buildings are now extending that requirement to water.”

Details Matter Finalizing the punch list, Forsgren says it’s important for employees and occupants to be aware if the building is carrying out a water management plan to use water more efficiently. “For example, if a hotel is carrying out a towel reuse program—but the cleaning staff does not understand why, or supervisors fail to follow up on implementation—savings that management is counting on will not be realized.”

It’s also important to update standard operating procedures and educate employees on the changes and the reason for making them. “Consider newsletters to update employees on progress or recognition programs for employees that come up with solutions that help achieve water-saving goals, says Forsgren.

“People working or visiting the building need to know that they are part of the program and that if they see water waste, they should be emboldened to report it to the proper personnel or suggest operation changes that include water use. Instead of being part of the problem, educated employees and occupants can become part of the solution.”

Best Practices in HVAC ›› Heat Pumps, VRF

Pumping Up Carbon Control A couple of trends are coming to bear in downtown Bridgeport, Conn.—adaptive re-use and “electrification.” The former is self-explanatory, the latter is a trend surfacing in California, Colorado (Boulder) and New York City, where it’s become the desire of various governmental entities to ween their citizens and businesses off of fossil-fuel-based HVAC, to those electrically powered, which, theoretically, would be powered by some form of renewable energy.

Last year at the AIA conference in New York, we addressed this issue in a special Net Zero Buildings’ panel, which was recapped in that magazine’s September issue. There, the focus was on VRF—variable refrigerated flow HVAC technology. But in the case of Bridgeport, its consultants went a different direction, and opted for heat pumps. Before briefly examining the differences, let’s take a look at the project.

Spinnaker Real Estate redeveloped three vacant, but historic buildings in the city’s downtown, into a single property, now known as Harral Security Wheeler (HSW), adding retail and commercial space on the lower levels, and more than 70 residential units on the upper floors.

With limited exterior space, installing air conditioning wall units was impossible without damaging the buildings’ historic architectural elements.

Working with consultants United Illuminating, the firm was able to retrofit the historic buildings with more modern lighting and heating equipment, saving them upwards of $50,000 in annual energy costs. The project was funded through a combination of historic rehabilitation tax credits, Brownfield programs, private equity and $26,235 in energy fund incentives. Using UI’s energy model, the upgrades could result in roughly $50,000 of annual energy savings. “The energy incentives allowed us to provide better and more efficient equipment in the building’s common areas, which are in use 24 hours a day, 365 days a year,” says Spinnaker Real Estate President Kim Morque. “The incentive shortened the payback period to justify the additional costs of the project. By their nature, Historic Tax Credit projects require subsidies to make projects feasible.

The energy incentive helped lower construction and operating costs,” says Morque.

With limited exterior space because of the large windows, installing air conditioning wall units was impossible without damaging the buildings’ historic

SHOT IN THE ARM

Th ree vacant downtown historic buildings, now known as Harral Security Wheeler (HSW), have been repurposed into retail and commercial space on the lower levels and more than 70 residential units on the upper floors.

architectural elements. As a result, UI turned to heat pump units. According to UI’s Glen Eigo, the engineer on the project, as opposed to VRF. “A VRF requires a central condensing unit and a problem with that unit can cause problems to multiple tenants,” says Eigo. “Also individual heat pumps make it easier to have separate meters for each tenant without the need for sub-metering. This makes each tenant responsible for their own utilities and the developer does not get involved.”

So, what’s the difference? According to Mike Smith, senior manager of marketing communications, Mitsubishi Electric Trane HVAC U.S.—the company is presently working with NYC and Boulder on electrification initiatives—heat pumps are designed to transfer thermal energy to and from interior spaces. At the most basic level, he says, a heatpump system consists of an outdoor unit connected to one or more indoor units via a pair of refrigerant piping. “During heating, the outdoor unit extracts ambient heat, and using refrigerant as the medium, transfers heat to interior spaces. During cooling, the indoor unit transfers heat from interior spaces to the outdoor unit where the heat is rejected,” says Smith.

He adds split-ductless and variable-capacity ducted heat-pump systems are popular among

residential and light-commercial architects, as these systems reduce or eliminate bulky ductwork and are more compact than traditional systems.

VRF, on the other hand, is more suitable for larger facilities. “VRF systems offer more connections to indoor units per outdoor unit, and provide greater capacities [tonnage] for heating and cooling compared to residential and light commercial systems,” says Smith, adding VRF systems can be ductless, ducted or a hybrid. “Heat pump systems are typically applied in moderate climates and in buildings with a single zone. In buildings with diverse requirements—such as a hotel, office or multifamily building—architects select heat-recovery VRF systems for simultaneous heating and cooling.”

Ultimately, he says, VRF systems and residential heat pump systems enable architects to design comfort zones of various sizes and with consideration for how occupants will use a given zone. “Each zone is served by at least one indoor unit, which can be controlled individually to customize comfort. The variety of indoor units include ductless options such as ceiling cassettes, wall-mounted units and floormounted units as well as ducted options such as low-profile air handlers, multi-position air handlers and horizontal-ducted units.”

Build it and... ... they will come—or so told the 1989 Kevin Kostner film “Field of Dreams.” For developers, and designers alike, such a credo may or may not prove the tipping point required to launch grand architectural visions.

The movie, ultimately, is as much about damaged relationships—and healing—between fathers and sons, as it is about baseball. Indeed, one might extrapolate that a similar dynamic exists between architects and developers—really anyone of a creative persuasion that’s paired with someone charged to watch the bottom line—or as frequently happens in the film industry—someone brought in to “save” a film so it might fare better with general movie audiences. In the case of the unique James Carpenter façade to the right, as featured on a retail portion of one the Hudson Yards buildings, the opposite proved true. A couple years back, I had the chance to interview the visionary designer as part of an international symposium on daylighting. When I asked him if there’s a specific profile in a client he looks for to grant him the freedom to pursue the intricate, yet functional kinds of signature façade treatments, the architect told me he tends to work with more institutional owners, but that doesn’t preclude him from working with developers. In fact, he believes his “crafted” systems, ultimately, stand for themselves, with the proof in the pudding being that if the building proves itself, “the developer will come back.”

Cheers to intrepidness.

Utilities Under Pressure from DG

Insightful Open Office Survey

Distributed solar-plusstorage systems are beginning to force electric utilities—and their regulators—to rethink business models, according to a recent international survey of utility executives.

Rapidly falling storage costs are beginning to make grid defection a real threat—95% of survey respondents say the number of consumers going primarily off-grid for their electricity will grow significantly in the next two years in this paradigm shift. Beyond 2025, 95% of surveyed execs said DG and storage-services could become profit centers.

As the debate over open offices continues, a Harris Poll survey, on behalf of Coldwell Banker Commercial Affiliates, found that 74% of U.S. adults are comfortable working in an open office if there are private spaces available, 73% agree if there is limited noise and distraction, and 66% are in favor if there is also a large meeting space.

Of the more than 2,000 people surveyed, 63% believe that their office could better utilize its physical space; 59% would like dining options; 57% are interested in enough parking; 37% want to see outdoor lounging spaces. www.cbcworldwide.com

With a national ABI score of just 50.3 (any score above 50 signifies growth) firms basically held steady from last month’s growth levels. However, scores for both inquiries coming into architecture firms and new design contracts continued to reflect healthy growth rates. With sustained improvement in inquiries for future projects, as well as new project activity, billings are expected to improve. February produced the highest ABI score for commercial/industrial firms in over a year, as it also was the lowest score for institutional firms in over a year.

STRUCTURAL WOOD

High-Tech Design with Local Materials Virginia Tech students create an emerging technology for wood construction.

As part of an ongoing applied research project, students from the Center for Design Research (CDR) at Virginia Tech’s College of Architecture and Design explored and created an emerging technology for wood construction. Comprised of students and faculty, the CDR team devised a structure that combines local materials with high-tech digital design and fabrication techniques. Fabricated by a robot, the innovative structure uses computationally-driven manufacturing fused with traditional woodworking to explore how advanced design and fabrication techniques can be applied in resource-limited settings.

Working with an industry partner like MASS Design Group, the CDR faculty and students intend to continue this groundbreaking work to apply it to cities in East Africa, Haiti and the U.S., to help to create sustainable, efficient structures that meet the needs of the community and enhance quality of life.

BLUE ROOFS

No Chicago H2O Blues With a mandate to account for total building mass and footprint, and that held stormwater be released within 48 hours, the client required something special: a “blue” roof.

Very near Lake Michigan in Chicago, Northwestern Medical Center faced several challenges in bringing a new campus building to life. Designed

by Perkins+Will, the project involves a phased construction where a 14-story base building is presently under construction; a 20-story tower addition is planned for construction in five to 10 years. Since the project is built-out to all property lines there are no at-grade landscape areas, which presented a particular challenge given the city’s Dept. of Stormwater Management permit requirement that the project account the total building mass and footprint. Translation: 10,000 cubic ft. of stormwater detention was required. Further, city code required that this volume be released through the flow control drains within 48 hours. This challenge was met with the implementation of a pair of “blue roofs.” A creation of American Hydrotech, the detention system is a composite of materials and products that can hold, and slowly release, large volumes of stormwater. According to Hydrotech’s Richard Hayden, the blue roof lies below layers of pavers and vegetation, with drains that utilize an insert with an orifice to regulate the flow of water out of the drain.

BLUE ROOFING

Roofs with insulation and ballast displace water, meaning better drainage; the more boards and ballast, the more displaced. A flat deck will drain with enough water, due to gravity.

Water volume created by the orifice in the flow control drains requires a place to go underneath the pavers and garden roof.

“Blue” roofs are created using Hydrotech’s Permavoid product, a structural plastic voiding component. The company has adapted this product for inclusion in their blue-roof assemblies. This 14-in. × 28-in. × 6-in. deep module has the ability to store nearly 0.5-cubic ft. of water per square ft. of roof area on a flat deck. It also serves as a base for the assemblies on top.

To optimize the blue roof storage, the roofs on this building, explains Hayden, were constructed with flat, zero-slope decks.

BLUE ROOF COMPONENTS

Pavers on Tabs Plantings Growing Media Permavoid (Water Storage Unit)

Monolithic Membrane Surface Conditioner Approved Substrate

“The standpipe determines the maximum depth of the water accumulated in the blue roof; it also acts as a safety feature by allowing excess water to flow unrestricted into the drain when the blue roof is full.”

CHICAGO INFILL NEEDS BUILDINGS THAT CAN HOLD AND DIVERT WATER

The Permavoid layer was covered in Hydrotech’s Hydrodrain drainage composite; three rows of 3-in. pavers were installed at the parapet to offset the buoyancy of the 7 in. of insulation below. Three rows of checker block units were installed in the leading edge of the garden roof assembly to reinforce the garden roof from the effects of wind.

LIGHTING

Germany’s First Net Plus-Energy Building Nestled behind large sycamore trees, the architecture of Freiburg’s new town hall catches the eye, be its oval shape, its intriguing glass façade intermixed with light larch wood slats on one side, or PV panels on the other. Inside, its LED lighting scheme helps with another story: the energy bottom line.

DAYLIGHT AND LIGHTING

With a diameter of around 10m, certain “rotundas” feature a central cylinder that houses a discreet private area flanked by circular consultation zones. Above each of these stations hangs a delicate lighting ring, suspended from the ceiling, which emphasizes the rotundas as islands of light in the hall.

Devised by DS Plan, in close cooperation with ingenhoven architects, Tropp Lighting Design worked with Austria-based lighting manufacturer Zumtobel to develop customized lighting solutions for a net-positive energy facility.

Roughly 1000 daily visitors a day make their way to the town hall to the Public Service Center, where people can apply for official documents, and take advantage of the range of city services. But rather than be greeted by windowless corridors, individual offices have given way to a spacious hall in

elegant white—flooded with light—that takes up the whole of the oval inner quadrangle. The eye is drawn upwards, first to the large skylights, and then to the wooden façade of the five office floors. Only then do visitors notice the four round service islands.

With a diameter of roughly 10 meters, these “rotundas” feature a central cylinder that houses a discreet private area flanked by circular consultation zones. Above each stations hangs a delicate lighting ring, suspended from the ceiling, which emphasizes the rotun-

das as islands of light.

At the same time, these rings illuminate workspaces without the need for any additional fittings.

Glare-free LED light has been achieved thanks to a multi-layer luminaire structure incorporating a diffuser and micro-prismatic optics.

The crucial increased CRI of >90 guarantees maximum light quality and color authenticity.

To help provide optimal support for visual tasks in the biaxial offices with just one luminaire, it was also necessary to be able to install the solutions in the middle

of the axes of the office raster. Stepping up to this challenge, Zumtobel developed a 3-m-long fitting based on its LINCOR product, combining a slim crosssection of just 63 mm × 64 mm, with a light output of 11,000 lumens. A perfectly defined CCT of 4000K, and outstanding glare reduction—thanks to the mini-cell structure—ensure excellent light quality, while the 70-30 ratio of direct light onto the workspace and indirect illumination of the ceiling also has a noticeably positive effect.

Brightness and motion sensors are integrated

Stepping up to this challenge, Zumtobel developed a 3-m-long fitting based on the LINCOR light product.

into the luminaires for added comfort and, more importantly, added efficiency.

Speaking of efficiency, the light level is permanently adjusted to provide the required illuminance of 500 lux on the desks—but only when it is really needed.

If all the employees leave the office, the

luminaires are simply switched off: no users, no light, no waste.

Achieving this blend of architecture, design and light to deliver the highest standards of well-being, design and energy efficiency have helped Freiburg Town Hall become Germany’s first net plus-energy administration building.

According to Dodge Data & Analytics, at a national level, the volume of multifamily construction starts in 2018 was $212.4 billion, up 4%—a moderate rebound from the 2017 3% setback. Of the top 10 metropolitan markets, four (Boston, D.C., Miami and NYC) reported greater activity in 2018, while six showed declines. For areas ranked 11 through 20, seven reported gains, while three reported declines.

“The brisk expansion for the economy during 2018 enabled market fundamentals for commercial building and multifamily housing to strengthen,” says Robert A. Murray, chief economist for Dodge. “This provided the backdrop for the healthy volume of commercial and multifamily construction starts.”

2019 may not fare as well, says Murray, as benefits of tax reform on economic growth are expected to wane, and bank loans become tighter. But beyond volume, the market is starting to show—perhaps as the result of a more selective clientele—a degree of evolution from standard fare. Following are a few trends starting to impact multifamily design.

STATE OF A MOVEMENT

Net Zero Rising According to the New Buildings Institute, the number of verified net zero energy buildings as of 2018, was 67, with 415 in the “emerging” category (not yet certified, or exploring a net zero outcome). This compares to 21 and 39, respectively, when NBI first started tracking these figures in 2012. California and Oregon account for half the buildings on the list, but net zero projects can be found in 44 states. Multifamily makes up about 16% of NBI’s building list; office represents 19%, and schools lead all markets at 37%.

Among verified buildings, 80% of the stock is between 5000 and 10,000 sq. ft.

However, in the “emerging” category, projects between 50,000 and 100,000 sq. ft., lead the category at 23%.

New Ways to Live

Passive House Prevails Affordable passive housing is taking root in New York City.

The 300,000-sq.-ft.

Chestnut Commons project in Brooklyn will provide 275 affordable housing units to formerly homeless and low-income households. Designed

by Dattner Architects and developed and operated by organizations with strong community ties—including Cypress Hills Local Development and MHANY Management— the design integrates

community and recreation spaces including a landscaped roof terrace, rooftop planting beds for vegetable cultivation, a satellite campus for CUNY Kingsborough Community College, a food manufacturing incubator, a credit union and a social services center. The 14-story building is being designed to PH standards and NYC Active Design Guidelines and is expected to achieve PHIUS pre-certification by mid-2019.

Sustainable features include solar panels and

passive solar shading in the form of deeply recessed windows and projected solar shades at the eastern and southern façades.

The building envelope is a combination of cast stone, exterior insulation and finish system (EIFS) and masonry cavity walls, and the backup wall consists of 6-in. steel studs with mineral wool insulation and exterior grade sheathing with a liquid-applied air barrier. The residential windows are highperformance casement uPVC assemblies with

steel reinforcement, and the fixed and operable glazing sashes use double-glazed insulated glass units that also achieve a high degree of acoustical performance. The masonry rain screen walls have 4-in. of XPS insulation, 1 in. of airspace and stainlesssteel wall ties, and the masonry relieving angles and window lintels are thermally broken and have cavity closure frames at the windows. Check out the March issue of Net Zero Buildings for more on this trend.

Cincinnati Music Hall Opens with New Tune After Extensive Renovation A Cincinnati landmark with a rich and unique history recently received a total facelift, restoring the facility to the grandeur it displayed when it opened 140 years ago.

Workers tackled a 16-month, $143-million project at Cincinnati Music Hall, which is the home of the Cincinnati Symphony Orchestra and several other cultural organizations, reduced seating capacity at Springer Auditorium from 3,417 to 2,263-2,524, depending on the configuration. The project included updates to the roof, exterior, Edyth B. Lindner Grand Foyer, Corbett Tower, Library and Ballroom.

In all, the project added 31,549 square feet in the same footprint.

“We’ve been in business since 1880 and take pride in our work on many of the iconic buildings in Cincinnati,’’ said Andrew Imbus, Project Manager at Imbus Roofing of Wilder, Kentucky. “This is a project that we are going to be proud of for a very long time.”

Music Hall, which was recognized in January 1975 as a National Historic Landmark by the U.S. Department of the Interior, also serves as the home of the Cincinnati Opera, Cincinnati Pops Orchestra and May Festival Chorus.

One of the most challenging assignments in the major remodeling effort was the roof. Imbus and his team had installed the previous roof in 1988. “It was worn, but still water tight,’’ Imbus said. “Some shingles were starting to blow off.”

Imbus’ first charge was to find replacement shingles that mirrored those of the past roof to preserve the historical appearance of the building. The roof also required new double leaf smoke hatches, manufactured by The BILCO Company of New Haven, Connecticut.

Imbus’ team installed seven DSH Automatic Smoke Vents. The vents, which measure 66 inches by 144 inches, are among the largest smoke hatches on the commercial market.

The smoke vents include a Thermolatch® II positive release mechanism that ensures reliable vent operation when a fire occurs.

The vents automatically release upon the melting of a UL-listed 165F fusible link, and a curb-mounted fusible link allows the latch to be easily re-set from the roof level. The vents are fully insulated and gasketed for weather tightness.

The vents are hard-wired to the fire suppression system and open electronically if the sprinkler system activates. Corken Steel, the local distributor of the smoke vents, and BILCO rep Joe DeFrain of Welling, Inc., worked with Imbus in procuring the roof hatches.

The vents were installed above the main hall, Springer Auditorium, and are designed to open in an emergency to allow smoke and hot gases to escape.

This allows better visibility and breathing conditions for audience members and performers to evacuate safely and aide firefighters in their containment efforts.

“This was an important project for Cincinnati,’’ said Joe DeFrain, a BILCO representative with Welling, Inc. “It’s part of a revitalization of the entire community. Everyone in Cincinnati knows the Music Hall.

We’re a third generation, family-owned company from Cincinnati, and we’re proud to have been a part of it.”

Fenestration Factors As with Passive House projects, greater attention to the envelope, as a whole, is occurring in the sector. Not only does high-performance glazing and curtainwalls that check thermal bridging matter, but window placement is key. The distinctive Arborescence development below, about an hour from Montreal, is a great example, as its large and well-placed windows, in concert with narrow floor plates, allow for better daylight penetration, while the recessed nature of the windows, in concert with the roof overhang, address glare. The project also highlights another growing trend: steeply pitched, and standing seam roofs. Beyond a novel look, when skylights are added, the pitch allows for a much broader beam within. Secondly, standing seam roofs are a natural pairing for the incorporation of photovoltaic panels, such as seen on the net-positive home on the following page.

THERMALLY BROKEN

Rooftop Roadmap As noted, vegetated roofs and decks are a major trend. That said, roof real estate is a major consideration, especially if there’s a desire for skylights or PV panels. “We currently exist in an age where builders are forced to balance multiple elements on a vegetated roof or any rooftop of a green-minded building,” says Brian Grohe, commercial sales manager with VELUX America. “Using just one positive impact solution, like PV panels, vegetated roof systems, pavers or a daylighting system alone, won’t allow you to fully realize your green-building potential. Rather, these products can and should be used in conjunction with each other for the best efficiency and return on investment.”

Skylights, according to Eric Wanner, head of business development with Solar Innovations, provide benefits beyond the rooms and areas they are specifically focused on. “Not only can skylights brighten a room for individuals, but those above will find the glow that escapes from the room beneath, offering a transformative lighting experience unlike any other.

Modern skylights also offer new paths of mobility, as with retractable and operable systems, they give access to more of the buildings than ever before.”

Of course, every project is different, and every building owner is going to have different objectives for their rooftop real estate, notes Nick Smith, national account manager with ZinCo USA. “Instead of thinking of all available rooftop technologies as a competition for space, maybe it’s a better idea to frame the design objectives into usability and function. Through this lens, there will be less apples-tooranges comparisons being made between the various technologies.”

According to Amber Ponce with LiveRoof, it’s not just about maximizing space, but making it accessible. When mechanical equipment is used on the roof, for example, the manufacturer encourages permanent paver or stone paths to ensure that the plants are not damaged when the equipment requires inspection or maintenance. In addition, when planning for PV arrays, they usually recommend using them in conjunction with the green roof rather than in a separate area. “Vegetation has a cooling effect, which can enhance photovoltaic performance,” she explains. “In this case, we would support the design team in selecting plants in the areas which may receive more shading due to the photovoltaic panels.”

And this can actually help out the panels, says Robbie Shannahan with Eco-Roofs. One of the advantages of vegetated roofs is their flexibility and versatility. “The cooling effect of a vegetative roof, when planted around and even under photovoltaic arrays, enhances their performance without detracting from the vegetated roof benefits,” she notes. And, selection of the right plants can allow a vegetative roof to be planted right around or even hide mechanical equipment.”

Another advantage of a vegetative roof is its ability to serve as a “blue roof,” which can capture and store large volumes of stormwater for a managed release. “Elements that create a blue roof can be located either under a garden roof or underneath a paver assembly, like Hydrotech Ultimate Assembly,” explains Richard C. Hayden, Garden Roof Department manager with American Hydrotech. “This creates the detention function many projects need to achieve.”

Blue roofs are not supposed to hold onto the water for too long; rather, they “detain” water for only a

certain amount of time. “This timing is designed to create space for the rain in the next storm.”

The system is installed on a high-rise project in a dense area of Chicago—Northwestern University’s Feinberg School of Medicine Medical Research Center 2 project (see product development on p. 22 for more details on the system).

PITCH THE RIGHT ANGLE

Roof real estate is valuable, and must be carefully considered, particularly for net zero homes. Pitch of the roof also significantly matters, as skylights on a 35-degree roof allow considerably greater solar penetration in a space vs. a window on an elevation, as shown in this net zero home by Schworer Haus KG in Germany, featuring Velux skylights.

According to Johannes Schworer, the roof can serve as a source of energy and light, really demonstrating the future of living “sustainable, comfortable and healthy.”

Daylight-filled townsquare-like spaces encourage movement and provide comfortable, collaborative areas at the British International School of Houston in Katy, Texas.

Targeting Daylighting Arguably one of the most important aspects of a holistic school building is high-quality daylighting.

In fact, the World Green Building Council reports that in classrooms with good daylight, students attain 5% to 14% higher scores in tests and learn 20% to 25% faster than kids who work in windowless spaces.

Looking at the big picture, Dina Sorensen, Assoc. ,   +, senior associate, who heads up the DLR Group’s Washington, D.C. K-12 education design studio, points out that designing to provide ample natural light, views to the outdoors and a variety of ambient atmospheres—while also reducing energy demand—is both an art and a science at the building scale. Ultimately, the goal of a holistic design is determining what end users require to effectively interact with their environment and tune it to meet these needs.

“The best way to develop comfortable daylighting is as early as possible in the project, looking at building orientation and massing strategies,” instructs Emily Koch, , ,   +, project interior designer, LPA Design Studios, Houston.

DLR Group likes to begin the integrated design process with very early shoebox energy modeling for quick simulations. “We also co-design with engineers to combine the best passive strategies with the most advanced active strategies, and strengthen the solution with a human-centered approach,” explains Sorensen.

Part of this process involves considering a wide range of daylighting products very early on, from

building envelope products to fixtures, lamping and controls. “We tend to favor a combination of strategies that bring the most natural daylight into a space from multiple directions and supplement with a daylight control system, dimmable LED fixtures, tunable lighting and solar harvesting/solar tubes,” she says.

In fact, tubular daylighting devices are quite popular for these K-12 applications, particularly where exterior glazing is limited or where the floorplate is too deep for the light to penetrate.

With regards to shading, Koch asserts that window roller shades on the interior are a must, with a 1% to 3% open factor allow for occupant control of daylight and views.

Meanwhile, Heather Jauregui,   +, +, , sustainability specialist, Perkins Eastman, Washington, D.C., favors external shading devices. Her team also likes to utilize Rhino software with a DIVA daylighting plug-in to calculate natural light, in both instructional and non-instructional spaces, and to model the sizing and location of windows and skylights.

The next key prong in health and wellness is ensuring a high level of IAQ. “Indoor air quality has expanded its reach in critical understanding as being a number one global topic for human and planetary health,” reports Sorensen. “When it comes to schools, air quality’s impact on cognitive function has become of enormous interest.”

A Harvard School of Public Health study, “The impact of green

help identify integrated strategies informed by nature density and airquality research. The firm’s designs are also shaped by WELL, LEED for Schools and Living Building Challenge green building frameworks for monitoring and improving IAQ. “Selecting and specifying materials that limit exposure to VOCs, flame retardants and polyfluorinated compounds, and doubling down on removing fine particulates through

Not too Hot, Not too Cold A study conducted by Harvard University’s Kennedy School of Government found that cumulative heat exposure inhibits cognitive skill development and that air conditioning in schools can mitigate this effect. The study, “Heat and Learning,” reported that without air conditioning, each 1°F increase in the school year temperature reduces the quantity of learning that year by 1%.

In order to efficiently deliver conditioned air, Nick Signorelli, principal, K-12 leader, Ashley McGraw Architects, Syracuse, N.Y., recommends displacement ventilation or chilled beams. With the former, conditioned air enters the room at its base, and is then exhausted up near the ceiling via a quiet, low-velocity supply and return system.

With the chilled beams, induction-style chilledbeam terminals induce

the primary airflow from the central air handling units to flow across the cool coils in the beams, lowering the ambient temperature in the room. “Because the airflow is approximately one-third of that required by a

conventional HVAC system, we can use smaller ductwork—which, in turn, reduces installation costs,” he explains.

On the other hand, LPA sees a central plant system or a VAV system as the most efficient

and long-term, costeffective solution as teachers prefer a thermostat in the classroom and the ability to open the windows. For children who spend time on the floor, radiant systems are a good fit.

“We have found great success utilizing either an in-floor radiant system, or radiant wall panels with low-average water temperatures of a dead-front panel to prevent student exposure to hot surfaces,” relates Roop.”

ACOUSTICS

H E A LT H + W E L L B E I N G

What Did You Say? Of course, when selecting an HVAC system, acoustics are an important consideration, especially in learning spaces.

As a baseline, PBA shoots for ambient noise levels at or below NC-30. “We generally utilize main duct velocities no greater than 800 fpm, branch duct velocities no greater than 500 fpm and air diffusion device neck velocities no greater than 500 fpm to minimize duct noise,” states Roop.

When necessary, sound attenuators can be designed into main ducts. Compressorized equipment should be located above corridors, storage rooms or other

utility spaces, but not above occupied learning spaces, he adds.

As for classrooms’ architectural surfaces, Herr recommends acoustic ceiling tiles and acoustic cloud and blade systems for the ceiling: perforated metal, wood panels or sound absorptive panels for the floors; and linoleum, rubber or luxury vinyl underfoot.

Leading the Charge In the grand scheme of things, architects are strategically positioned to advocate for health and wellness for today’s school buildings.

To be best equipped to rise to this challenge, Perkins Eastman regularly conducts extensive post-occupancy evaluations on all its work. “Through this research, we have been able to tweak and perfect every school that we design to be even better than the last,” relates Jauregui.

Similarly, one of LPA’s mantras is “Prove it,” directing the firm to

Overall, Sorensen emphasizes the importance of integrating the building sciences with human development and performance science. Along these lines, “DLR Group nurtures a research, education and practice function, and serves as a Think Tank toward creating new knowledge in topic areas such as IAQ research, student and

teacher engagement research, and a forthcoming platform for healthy, active schools.”

Ultimately, Sorensen concludes, “we also need to forge new opportunities that make it easier for school districts to partner with researchers, policy makers and practitioners in education and design to facilitate a strategic whole school, and a whole community, whole child holistic approach to make health a priority for every member of their learning community.”

Faith, Hope and Patience In sustaining humanity, modern medicine often “alters” the state of the body; maybe it should be so with venerable buildings.

Pardon this moment of melancholy, but as I ponder the shingles below, I can’t help but think of the tragic fire that destroyed the roof of the Cathedral of NotreDame de Paris, last month. I’m also thinking about how, in the renovation work that preceded the fire, more modern materials, methods and fire-protection measures might have helped mitigate the awful horror. I’m not the only one, as in the aftermath of the devastating conflagration, debate sprung forth

In the aftermath, debate has sprung forth about whether reconstruction should center on pure restoration, or, perhaps, crafting something new. about whether reconstruction should center on pure restoration, or, perhaps, crafting something new.

Having been to the cathedral, and counting climbing to the top of the bell towers as one of the most memorable moments of my life, I actually stand with the camp suggesting something new might be the path to follow. It may be inevitable simply for structural and life-safety reasons, but there’s another reason: Hope. In the relief I felt when the fire was finally checked, and its treasures saved, I began to think that from this tragedy, perhaps, the community which loves this old building and what it stands for, can come together again. Indeed, I couldn’t help but remember the feeling I had in visiting Gaudi’s still-under-construction Sagrada Familia basilica in Barcelona—a feeling of joy, in that this project, 100 years in the making, draws in so many people, and creates a strong conviction among its visitors to see it completed; people are part of it. My hope is that something similar can occur in Paris.

Of course, new with old can look wonderful. Immediately to mind comes the temporary Canadian Parliament project we covered in January.

It, by no means, is near in maturity or grandeur as Notre Dame; still, hints of the Gothic, married with something more modern and functional, work in harmony—a goal for which we should always strive.

GREEN GAS While gas stations aren’t typically the first thing to come to mind when someone says “green building,” a St. Louis area gas station challenges that perception. The ZOOM station’s unconventional-looking canopy over its gas pumps supports a two-way solar panel system capable of producing 109,000 kWh of electricity annually—enough to power most of the station and its convenience store and car wash. Manufactured

by Prism Solar Technologies, the glass-on-glass solar panels can generate 35% more energy per watt than traditional modules via advanced bifacial N-type silicon cell technology that can generate electricity on both its front and back surfaces. The panels also offer exceptional performance in low light conditions due to the additional energy produced by its back surface. Circle 375

STUBBE HQ, HARLEY, ONTARIO A provider of architectural precast and ready-mix concrete, Stubbe, for its new building, wanted an R-value of 32 (in four in. of thickness), with exterior walls delivering an R-value of 35. A product that just launched as they were in design, Kingspan’s Kooltherm K20 Concrete Sandwich Board for tilt-up and precast walls, seemed heaven sent.

“It gives an R-value of 34 in a reduced thickness, where most insulation gives an R-value of 5 per inch,” says Stubbe Project Manager Albert Meyer. The insulation, he adds, delivers an R-value of 14 in the same thickness. From a transparency perspective, it is made with a blowing agent that has zero ozone depletion potential. Circle 374

Kooltherm K20 has a closed-cell structure, so it keeps out moisture and water, is resistant to fungi and is very stable. The product has a fi ber-free core, enhancing its smoke development properties and fi re performance.

With its cylindrical core and extending arcs, the museum almost appears to be in motion–a sense of movement reinforced by the running lines of the structure’s corrugated metal wall and roof panels.

THE MUSEUM BUILT BY GATORADE Gainesville, Fla., recently added an unusual new institution to its cultural landscape—the Cade Museum for Creativity + Invention, which is dedicated to both commemorating and inspiring the kind of innovation that built its namesake founder’s career. Dr. James Robert Cade is best known for inventing Gatorade, but his inventions stretch from football helmets to protein shakes. The museum’s design,

by Baltimore-based GWWO Architects, features a circular core and extending arms that create a sense of motion.

Corrugated metal panels clad the façade, complementing the high-tech image that’s at the heart of the museum’s mission. Circle 372

PANELS IN HARMONY Brasserie Bernard is a classic French brasserie in the heart of Outremont, a high-end neighborhood in Montreal, Canada. Owners of several popular restaurants, brothers Maurice, Paul and Richard Holder knew from experience that acoustics are an important part of developing an ideal atmosphere. To create a space that allows for comfortable communication, the brothers selected lightweight, WILLTEC direct-apply panels. In addition to providing acoustic benefits, the custom golden-yellow panels harmonize with the multidimensional painted ceiling and walls, and contrast with the black wood and leather banquettes. The WILLTEC custom panels are finished with a specially formulated water-based, golden-yellow acoustic coating. Circle 369

The insulation improves wall assembly STC ratings by up to 10 dB, has a melting point in excess of 2000˚F and is made of durable inorganic glass, which translates into no growth of fungi and no sustaining of vermin. JM mineral wool is also easily cut, installed and fills the entire cavity for maximum performance. It is best used in wood-stud cavities and interior walls and ceilings between floors to deliver noise control.

FORM AND FUNCTION TAKE FLIGHT Inspired by air traffic maps, Tarkett has introduced two new lines of modular carpet tiles, offering new options for office, education and hospitality spaces. The designs could simplify installation in contemporary architectural designs where right angles and straight lines give way to open, multi-use spaces and curved walls.

The carpet uses Tarkett’s Powerbond construction, with means it can be installed in any direction (even diagonally). The designer Jhane Barnes flipped and rotated repeating modules to create a large-scale pattern with no obvious repeat, creating an intriguing visual with minimal installation water. FlightPath contains 14 different matching points in its 22-ft. pattern repeat-that’s an opportunity every 19 in. for seams to align. AirSpace uses the same concept on a smaller scale. There are 24 hues in each of the three mix-and-match pattern options and are available in three sizes of planks and tiles. Circle 362

Graphic Concrete: It’s the new face of precast.

Graphic Concrete gives you the freedom to impart nearly any pattern, image or design onto resilient precast wall surfaces. The versatile technology transfers custom or stock graphics as a surface retarder via a membrane placed at the bottom of the precast form. After the concrete is cured and extracted from the form, the retarder is washed away, revealing an image that results from the contrast between the fair-faced (smooth) surface and the exposed aggregate surface. It is as durable and maintenance-free as concrete itself. You can select various aggregates and pigments to dramatically expand possibilities in the finished surface. Precast concrete has a new look.

And it’s bigger and more beautiful than ever.

Colorado School of Mines Located at the foothills of the Rocky Mountains, the Colorado School of Mines in Golden, Colo., has a backdrop few campuses can emulate. While many campus buildings are historic, the new CoorsTek Center for Applied Science and Engineering, named for the local and international ceramics manufacturer, shines as a modern visual centerpiece at the heart of campus, reflecting the research and sciences it champions. With its unique shimmery face, the center changes with the time of day to reflect the nearby quad.

Curtainwall EFCO

The northwest exterior, which fronts Kafadar Commons, the campus green, consists of full-height glazing at level 1, using the Series 5900 Thermal Curtain Wall with Duracast Fiberglass Pressure Plate.

“The vertical fi ns and texture, mullions and puzzle pieces—or portions that push in and out—are also reflected on the interior as a way to break down the façade while adding visual interest,” said Kirk Hostetter, senior associate, Bohlin Cywinski Jackson. “There was a concern about integrating with the scale of historical buildings on campus, and this was a way to break down the glass façade.”

According to Robert Miller, principal at Bohlin Cywinski Jackson, in conjunction with architects of record Anderson Mason Dale Architects, it is the building’s many open spaces that have made it a new campus favorite. “There are places for people to pause, which creates cross pollination between students of different disciplines.” Miller says the Coorstek Center and its neighbor Marquez Hall— also designed by Bohlin Cywinski Jackson—have successfully created a “new campus standard.”

Vertical Fins EFCO Vertical metal fins complement vertical glass panels at levels 2 and 3, that float above, and modulate, as influenced by the building’s interior program.

Converging Architectural + Performance Goals

Unisphere A Clinical Success: United Therapeutics’ Unisphere is a functioning work of building science and applied environmental art, creating a new gateway for both the city and the campus.

United Therapeutics’ (Unither) Unisphere is the largest net zero commercial building in the U.S. A biotechnology company focused on the development of products to address the needs of patients with chronic and lifethreatening conditions, Unither, in planning the 210,000-sq.-ft. addition to its six-building campus in Silver Spring,

approached the project, in the same manner as the development of one of its products. They identified a primary objective: build a facility to keep up the design and development flow of the company’s new products; second, create a building that would exemplify a new environmental theory to the structures of this genre; and third,

create a contemporary landmark for its campus that would also function as a gateway into downtown Silver Spring.

“Unither views its buildings as physical manifestations of its values and its mission of saving lives,” says Jared J. Loos, AIA, PE, CEO of EwingCole, which combined its in-house staffs for architecture, engineering and interior

design, working on the project which spanned a seven-year period until its Sept. 21, 2018 opening. Elliptical in profile to mimic the shape of the universe, Unisphere operates at approximately half of the energy level than other office buildings in the D.C. region, fulfilling the company’s resolution that the structure be net zero, using the

energy that it produces onsite. “Every element, from the overall building form to the interaction between building systems, was evaluated against multiple options to optimize energysaving strategies,” Loos points out.

The firm worked across all disciplines to develop viable solutions at every phase of the project.

”We met regularly with United Therapeutics to present our proposed solutions and receive feedback and suggestions on further developing these strategies. This integrated approach between owner and A/E team created a unified vision that we all understood and supported,” Loos indicated.

5/1/19 5:39 PM

Building Façade and Exterior The building took on many shapes in early design as the A/E team used solar and shading studies to evaluate stepping and sloping the façade in various directions. The design solution was to taper the façade with horizontally oriented solar panels located above the vision glass on the south façade. PV panels double as sun shades to the vision glass, blocking high summer sun but allowing in low winter sun when it is desirable. The elliptical shape maximizes solar exposure by creating gentle changes in plane.

Its axis was rotated from the city’s grid to align with cardinal directions, extending from east to west. “We evaluated the building’s solar exposure in Ecotect and PVSyst to determine the most productive locations for solar panels,” noted Jason Fierko, EwingCole’s director of energy management. The amount of rooftop equipment with space required for solar panels was applied to the design of a sloped solar tray approximately 20 ft. above the roof level that extends to the buildable limits. “In this way, it was possible to maximize solar production and to minimize adjacent building shading,” Fierko explained.

Daylight modeling was completed in DAYSIM and imported into the Carrier HAP energy model. Nearly 3000 on-site photovoltaic panels are mounted onto the building’s façades or roofs.

“The building is an engineering marvel, and a beautiful one, in that it depicts its inner workings. The result is pretty amazing. There is no building quite like this. This truly is one of a kind. It sets a new bar for sustainability.”

Passive to the Max As originally envisioned by Unither’s management, the Unisphere would achieve zero net energy with enough renewable energy produced on site to sustain itself over the course of a year (it delivers 1,175 MWH annually). The building was permitted to be only as large as could be supported by on-site solar production.

The energy model was first created at the pre-schematic stage. Fierko and his team used multiple tools, including EPA’s Target Finder program, CBECS data, other net-zero building case studies and benchmarking of other United Therapeutics buildings to ensure that the verified energy usage aligned with the model’s projected consumption. ”The model was continually updated throughout design and construction with several hundred iterations performed,” says Fierko. “As more net-zero building data became available over the design phase, we continually benchmarked to ensure our goal was both challenging but achievable.”

Passive energy saving strategies were selected for their durability, low-energy use and effectiveness.

Daylighting strategies are integrated into the façade of the building with translucent, high-insulation glazing from 8-ft. above the floor to the ceiling. The façade is broken into modules within each level, with: translucent glazing at daylight panels; triple-glazed, low-e coated electrochromic awning windows at vision height; triple-glazed shadow box spandrel below vision glass; and an operable awning window below the access floor for natural ventilation. The electrochromic glazing automatically tints based on weather conditions.

The building communicates its operations that generate 1.175 MWh annually, to occupants and passersby. For example, when the building is in natural ventilation mode, interior lights in key locations change color, and awnings open to bring in outside air. The ground, itself, is also used as a heat exchanger to reduce the heating and cooling demands of the building. Heating and cooling is done through a geo-exchange system with (52) 500-ft. deep wells tied to highly efficient water-towater heat pumps. An active chilled beam system provides cooling to the office spaces and utilizes one-third the amount of air as a traditional cooling system. Heating is supplied to the offices through a highly efficient perimeter heating system that relies on natural convection of air within the space.

Total energy recovery on all air streams along with a super-insulated envelope is included to mitigate the effects of climate.

NOTHING TO MOCK A major key to success was the fact that United Therapeutics chose to invest in a full-size mock-up that spanned from the exterior to the atrium. Th is way, the team was able to improve construction assemblies, and evaluate multiple devices, saving Unither millions of dollars in change orders.

Application is pending for LEED Platinum certification. A post-occupancy evaluation will be conducted within 18 months of occupancy.

Interior Systems Interior finishes were selected not only for aesthetic qualities, but also their durability and recycled content, such as the carpeting, made from fish netting. Employees appreciate a high level of occupant control within their spaces: individual temperature controls with set point restriction to support the building’s efficiency goals. Active chilled beams and under-floor radiators provide heating and cooling to the office spaces. Operable windows let fresh air in during ideal natural ventilation periods.

Ceiling fans within each office provide air speed control, while electrochromic glazing adjusts tint levels to eliminate unwanted glare and solar radiation. The HVAC systems utilize a MERV 13 filtration level to reduce particulate and densely occupied spaces, such as conference rooms, are provided with carbon dioxide sensing to ensure optimal air quality. Indoor materials are specified to be low or zero VOC to prevent off-gassing.

A pool in the atrium doubles as a heat sink.

Acoustic privacy was a concern in the semiopen office plan. Provisions for sound deadening ceiling panels and a noise-canceling system was included in the design.

ENERGY DIAL

During daylight hours, the building is expected to provide 100% of its instantaneous use plus a renewable export of energy to the local grid. To supplement this approach, a backup generator and uninterrupted power supply system is provided to ensure critical functions can continue within the building in the event of an electric utility outage.

All six fl oors of the atrium have glass façades facing the Energy Dial, a symbol of the relationship of those who work in the building with the building itself. Th e “Energy Dial” is comprised of light and reflective metal fi ns, recessed into the building’s interior shell. It reacts to real-time data from the building’s control systems.

University of Iowa’s Music Renaissance The disastrous 2008 flood in Iowa led to the necessary closing of the long-standing Voxman Music Building at University of Iowa.

CHALLENGE

As a result of Hurricane Michael, school leadership knew that they had to completely relocate, as well as redo the entire building to better fit student needs.

With $743 million in FEMA aid, the University of Iowa embarked on a mission to rebuild. As part of this reconstruction effort, the university hired Seattle-based LMN Architects and local firm Neumann Monson Architects to relocate and rebuild a new $189 million, state-of-the-art, Voxman Music Building in downtown Iowa City. Lighting design firm HLB Los Angeles was brought in to create a wellorchestrated, yet quiet symphony of light that would enhance the finished color palette and promote the functional needs of the students, staff and visitors of the 184,000-sq.-ft. building.

USAI Lighting www.usailighting.com Circle 193 PROJECT SPECS

INFLUENCE

The Voxman building was envisioned to be a concrete structure that would resemble a bento box in which simple tones and a minimal color palette would be used. The rehearsal spaces were meant to be spaces of inspiration that also offered the most optimal lighting conditions for students to read sheet music and practice. In each rehearsal space there are sculptural kites hanging from the ceiling that are designed to swarm and cluster to assist with the room’s acoustical properties. The lighting that was to be interwoven into the space needed to highlight the architecture to inspire students during rehearsals.

CRITERIA

The six-story music building is designed for resiliency, sustainability and acoustic performance. As a project defined by a dramatic interplay of volume and light, the lighting design demanded a high level of coordination and collaboration to provide viable solutions for large-scale design challenges.

SOLUTION

USAI Lighting’s BeveLED 2.1 Color Select fixtures were incorporated into these spaces given that they provided the highest intensity with the strongest uniformity in these rooms. Another critical element that these fixtures provided are their level of hardware that wouldn’t be affected by the constant and intense sound waves produced in the rooms by student performers. The USAI BeveLED 2.1 fixtures’ sleek design, stellar hardware and light intensity didn’t take away from the space’s design, but rather offered precise lighting conditions that brought to life the Voxman building unlike ever before.

Getting Back on Track with Style With a concentrated effort to revitalize the downtown of Cliffside Park, N.J., Park Town Centre—13 stories of rental apartments atop a two-story retail level—was eyed as a way to bring new energy into a tired business district.

CHALLENGE

Find a more efficient and cost-effective structural façade system to complete a planned mixed-use development that ran into economic issues.

INFLUENCE

Town officials in Cliffside Park, N.J., had big plans for revitalizing their downtown when they began assembling properties for a new, signature mixeduse development back in 2002.

CRITERIA

The central location and magnificent opportunity for views across the Hudson River to Manhattan would seem to make the Town Centre’s site a no-brainer for a signature residential high-rise. But the area had, instead, languished, earning the designation of “redevelopment zone” when this project was first envisioned. Cliffside Park planners hoped the effort

would kick-start interest in the surrounding downtown district. The quick access to the George Washington Bridge would also provide a more affordable housing option than Manhattan.

“The intent was that it was going to replace underutilized properties to revitalize the center of town,” says James T. Virgona, architect with Edgewater, N.J.-based Virgona + Virgona Architects and the designer of the project. However, just as the 3.3acre property was secured, the Great Recession put the project on hold. When it started up again, a new hurdle emerged: under-surface conditions including a base of extremely hard rock and a previously unknown underground spring. The latter forced the design team back to the drawing board, as it meant the entire project had to be raised by 4 ft. to 5 ft.

Already leaning toward “classically inspired modernism,” Virgona doubled down on this approach as

the raised site began to resemble a plinth—the base of many traditional Greek and Roman columns. That plinth has taken the finished form of a broad public plaza, with a decorative fountain and surrounded on three sides by two stories of retail space.

Virgona’s design incorporates a staggered-truss structural system that frees up interior space. Using floor-to-ceiling steel trusses in a pattern that alternates from floor to floor, this approach transfers the entire building load to exterior columns. “The structural system used about half the steel as a typical design,” Virgona says—though he noted the 13-story project still required more structural steel than was used in New York City’s Madison Square Garden.

SOLUTION

SlenderWall assemblies, which combine an exterior architectural precast concrete panel with vapor barrier, closed-cell foam insulation and galvanized framing studs, provided significant labor savings.

The panels’ unique M-shape also allowed for larger windows, giving future tenants even greater access to dramatic views of the Manhattan skyline.

As is typically the case, the staggered truss system was paired with precast concrete plank flooring. The floor planks were fabricated with embed plates for connecting the SlenderWall exterior panels. This installation process was choreographed to such a degree that, according to Virgona, “the panel façade was being applied to the building even as the structure above was still being constructed.”

Acid-washed and sandblasted finish options ensured both designer and developer would get the natural stone appearance along with extensive decorative reveals and projections they desired.

Geothermal Contributes to Net-Zero Success When investors started planning the 2062-acre Whisper Valley sustainable, planned community east of Austin, Texas, one of their biggest challenges was to attract home builders to join the project and actually build the homes.

CHALLENGE

SOLUTION

One of the challenges, explains Douglas Gilliland, managing director of developer Taurus Investment Holdings, was to convince home builders to do things a bit differently. “Builders have established construction practices. They’re used to doing things a certain way because it has always worked for them.”

All builders in Whisper Valley are required to hook up to EcoSmart’s GeoGrid, a 5-mile loop of underground distribution piping that links each home to a geo-exchange network, engineered and manufactured by REHAU, a global provider of hydronic technologies and a strategic partner in the Whisper Valley project. “It took a bit of time to figure out who was doing what,” says Dennis Ciani, head of marketing for Pacesetter Homes, an Austin-area builder that constructs about 500 homes per year, including most of the new homes in Whisper Valley. “But the geothermal loop was already in the ground and all homeowners had to do was tie into it, which turned out to be fairly easy to do.”

Whisper Valley incorporates a new business model in home building that consumers are demanding: net-zero energy capable homes selling at prices most consumers can afford—all in a planned community that itself is “sustainable.”

INFLUENCE

EcoSmart Solution a subsidiary of Taurus Investment Holdings, brought together the technologies needed to make a zero-energy capable community of this size possible with affordable prices. The EcoSmart program combines an innovative GeoGrid, solar PV, high-efficiency Bosch appliances and Google Nest products to make the vision for communities like Whisper Valley a reality.

Builders were also required to adjust their floor plans to accommodate a geothermal heat pump to be located in each home’s insulated attic for maximum efficiency. As it turns out, Ciani says, “We didn’t have to alter our floor plans very much.” And when consumers learned that their heating and cooling capacity came mostly from the earth—and that the cost of the system was already embedded in the home price—“it became a major selling point.”

“Another selling point was reduced monthly costs of living through dramatically lower energy bills,” Ciani continued. “The sustainable technologies—the geothermal system, solar photovoltaic panels on the roofs and computerized controls in each Whisper Valley home—probably adds $15,000 or more to the price compared to similar conventional homes in nearby rural communities east of Austin,” he says.

But when people consider the price of the home, they don’t always consider its monthly costs.

In central Texas, where temperatures average above 90°F during the summer months and can dip below freezing during the winter, utility bills are an enormous monthly cost. Whisper Valley’s integrated geothermal and solar systems bring those costs down to next to nothing—a reduction of $150 to $300 per month in the overall monthly cost for homeowners.

Whisper Valley residents also benefit from federal tax credits for both the solar PV system and the geothermal equipment included in their homes.

Residents can expect a $7,000 to $10,000 tax credit, providing additional savings on their zero-energy capable homes.

LOWER UTILITY COSTS

In central Texas, where temps average above 90 degrees in the summer, utility bills are a considerable monthly cost.

The integrated geothermal and solar systems can bring those costs down.

Daylighting

Wing at Florida Mall Offers Sunlit Experience Florida’s Aventura Mall recently completed a new wing expanding the Miami-area retail destination by 315,000 sq. ft. to 2.7 million. Providing a sunlit experience with indoor conveniences, a custom, vaulted skylight was installed.

CHALLENGE

CRITERIA

Opened in 1983 at less than half its current size, Aventura has grown steadily through the decades.

The newest addition on the eastern edge was completed in March 2018. “Retail is certainly evolving and we’re always innovating to stay ahead of the curve,” explained Jackie Soffer, co-chair and CEO of Turnberry Associates, owner and managing entity.

With 2903 hours per year of sunshine and 62 in. per year of rainfall, the skylights bring the outside indoors without the inconvenience of precipitation or unwanted solar heat gain.

JPRA Architects served as the project’s architect of record, working with general contractor Plaza Construction Group and design architect Carlos Zapata Studios. Super Sky Products Enterprises manufactured and installed a 347-ft.-long, 96-ft.-wide, custom, vaulted skylight to crown the addition.

INFLUENCE

According to Turnberry Associates, “Zapata’s guiding principles—connectivity, integration and transparency—are the hallmarks of the wing’s distinctive design, and complement Turnberry’s progressive vision. Everything is bathed in the sun’s rays filtering through a continuous skylight that hovers over the entire length of this modernist extension.”

SOLUTION

Supporting Aventura Mall’s bright, modern design, Linetec finished the skylight’s aluminum framing components in a Pale Oak color. Upholding the specified appearance and functionality, the durable, 70% PVDF resin-based finishes also complement the skylight’s high-performance Viracon glass to keep shoppers comfortable beneath the warm, Florida sun.

Skylight manufacturer and installer, Super Sky, incorporated nearly 11,000 sq. ft. of Viracon’s VNE163 clear, insulated, heat-strengthened glass with white, 40% dot frit silk-screening and low-e coating. The 0.5-in. air space with stainless steel spacers improved the insulated glass units’ thermal performance for energy efficiency. The StormGuard enhanced PVB interlayer also optimized performance for large missile impact hurricane-resistance.

“Performance in coastal conditions also is one of the most challenging environments for aluminum,” says Linetec’s senior marketing specialist, Tammy Schroeder, LEED Green Associate. “Without proper precautions and finishes, corrosion to aluminum components can damage the building envelope’s structural integrity, leading to systemic failure. With skylights—especially those located in a region prone to high winds, tropical storms and hurricanes—structural integrity is critical to protecting both property and people.”

To stand up to harsh coastal or corrosive environments, Linetec recommends the highest-performing organic paint coating meeting the American Architectural Manufacturers Association 2605 specification. This specification requires paint coatings to meet rigorous testing performance standards including more than 4,000 hours of salt spray, and heatand humidity-resistance. These 70% PVDF resinbased coatings also shield the aluminum against weathering, pollution and aging, as well intense UV radiation, attributes that contribute to long-term chalk resistance, gloss retention and color retention.

CROWNING ACHIEVEMENT

Envisioned as a contemporary town square, Aventura Mall’s three-level wing incorporates a custom, vaulted skylight, which crowns the new addition.

Pinellas County Chooses Composite Decking Realizing that the boardwalks surrounding the tower and fishing pier were worn, park engineers chose to replace the decking for both the boardwalks and piers at the scenic Wall Springs Park in Pinellas County, Fla.

CHALLENGE

The 35-ft. tall observation tower at Wall Springs Park in Pinellas County, Florida, offers stunning views of the park and the Gulf of Mexico beyond. A regional gem, the tower and about 30-ft. of ramp leading to it were destroyed by arson in 2013. In the midst of an arduous five-year reconstruction project, park engineers realized the boardwalks surrounding the tower and the fishing pier were worn and rotting.

They chose to replace the decking with composite decking for those areas to reduce maintenance and increase longevity.

CRITERIA

“The original boardwalks installed in 2002 had begun to deteriorate and were becoming a safety hazard,” says John Linton. P.E., senior engineer, parks engineering and design, for Pinellas County. “We then changed the scope of the tower project to include new decking for the boardwalk and fishing pier so

the whole area of the park would be updated and safe by the time the tower reopened to the public.”

they receive very little sunlight and are moist most of the day.

SOLUTION

“When we first built the boardwalks, the cost of composite decking was considered astronomical.

Now, we’re finding the pressure-treated wood doesn’t hold up as long as it used to and we’re facing more frequent, costly replacements,” says Linton.

“The longevity of the composite, as well as the reduced maintenance needs, have made it much more cost-effective.”

MoistureShield Vantage is an uncapped wood composite board with a matte finish that evokes the look of real hard wood. “The color is consistent throughout the board and it cut just the same as wood—even better because it didn’t splinter when cut,” says Linton. “And, with wood-grain texture on both sides, contractors didn’t have to worry about which side they were flipping up.”

Additionally, MoistureShield’s SolidCore technology runs through the entire board to ensure protection without a cap. There’s no need for painting, staining and yearly repairs and Vantage is completely resistant to moisture, rot and warping. This was significant in Wall Springs Park because most of the boardwalks are in submerged swamp areas where

For longer spans required by commercial boardwalks, the 2 × 6 profile of Vantage was used for the decking. The boardwalks are 6-ft., 9-in. wide with an inside handrail. Linton points out Vantage was the only of the composite products they looked at that offered a 2 × 8 profile that could be used for the top plates on the railings. The rail system has a 6 × 6 post and 2 × 2 rails with galvanized metal mesh inset.

uildings consume energy in three different ways; energy is consumed to create the various products and materials that make up the building; energy is consumed during the physical construction of the building; and energy is required to create a comfortable and functional interior, once the building is occupied. When the sustainability movement began in the 1970s, it was focused primarily on reducing the amount of energy necessary to keep a building operational. To that end, energy codes and green building rating systems were developed to help designers create buildings that operated more efficiently. Now, sustainable design is entering a new era, where the industry is demanding not only that the buildings be designed to be more efficient, but that proof is gathered to verify that the buildings are actually working more

efficiently. There is also an increasing level of interest in reducing the amount of energy consumed by the materials and products selected for a project.

This article explores the performance and materials efficiency considerations as they relate to low-e glazing, architectural cladding, wood products, solar shading fabric, and the materials selected for bathroom partitions and washroom accessories.

ALLOW DAYLIGHT, MANAGE SOLAR HEAT GAIN

Connecting people to the outdoors by providing views and allowing daylight to penetrate a space has become a key tenet of sustainable design, especially as a growing body of research reveals the benefit of these exposures to the health, wellbeing and productivity of building occupants. However, there is a caveat. The inclusion of daylight and views must be done without undercutting the efficiency of the building or subjecting people in the interior to the discomfort that can be caused by glare and solar heat gain. This requires designers to do more than simply fill a façade with glass, they must equip that façade to manage the light and heat present at the window.

Solar energy is dynamic and diverse. It contains visible light and infrared and ultraviolet radiation.

The visible light portion of the sun’s energy can range

by Cesar Pelli, uses low-e glass to manage solar heat gain and create a striking and sophisticated façade.

in intensity from 10,000 footcandles (fc) on a bright sunny day, to a few hundred when overcast. Although infrared and ultraviolet radiation may pass into a building unseen, they can have a profound effect on the efficiency of the HVAC system and the comfort of the people inside. When infrared radiation is absorbed by carpets or furnishings, it transforms into radiant heat, which raises the temperature of the interior.

When solar energy reaches a building façade, the façade can reflect it, absorb it or transmit it into the interior. Low-emissivity glass, often referred to as “lowe” glass, is designed to manage the amount of visible, infrared and ultraviolet light that passes through the glass and into a building, with the goal of allowing as much visible light as possible to pass through, while blocking high levels of the heat-creating infrared energy.

Advancements in low-e coatings have improved the effectiveness with which the glazing is able to distinguish visible light from infrared and UV radiation, better protecting the interior from solar heat gain, while allowing it to be filled with daylight. Beyond better performance, a wider range of clarity, color and reflectivity options enable designers to achieve the

performance they need with the aesthetic they want.

The secret is in the microscopic layers of metal that are deposited on the glass.

SOLUTION

LOW-E GLASS WITH LAYERS OF SILVER

The coatings applied to low-e glass feature several thin metal layers. Although each layer is less than 1/1000th of a human hair, they deliver sophisticated performance enhancements that allow the glass to transmit more visible light into a building, while reflecting a higher percentage of the infrared and UV radiation.

The layers can also impact the color, clarity and durability of the glass unit.

Of the various types of metals and oxides combined in a low-e coating, silver has a dramatic impact on the insulating performance of the glazing. There are low-e solutions referred to as single-silver, double-silver and triple-silver low-e glazing, with triple-silver glazing containing the most layers of silver within the coating and delivering the most energy-efficient thermal performance.

Thermal performance refers to the amount of heat that is gained or lost through an insulated glass unit (IGU). There are several metrics used to quantify and compare the thermal performance of a glass solution.

The solar heat gain coefficient (SHGC) refers to the amount of the sun’s energy that passes through the IGU and into the interior. An IGU with a SHGC of 0.27 will allow 27% of the solar energy to pass into a building, successfully blocking up to 73%. Lower SHGC values indicate that the glazing does a better job of preventing heat from being gained by exposure to solar radiation.

There are triple-silver low-e coatings on clear float glass can offer SHGCs as low as 0.23. Before the triple-silver

innovation, designers were often required to specify glass with heavy reflective properties or a dramatic tint to get SHGC values that low.

The U-factor is another metric that describes how well a window assembly insulates the interior by measuring heat gain or loss due to the difference in temperatures on either side of the IGU. Lower U-values indicate that less heat travels through the glass, making the window a better insulator.

When creating a project to include more daylight in the interior, while reducing solar heat gain, it is important to explore the amount of visible light that will pass through the glass. This aspect of performance is referred to as visible light transmittance (VLT). A clearover-clear IGU without a low-e coating can achieve 85% VLT, meaning that 85% of the available visible light passes through the glass and 15% is reflected or absorbed. The high-end VLT that is available from a low-e product is roughly 75%.

Another key metric is the Light-to-Solar-Gain (LSG) ratio, which compares the amount of visible light transmitted through the glass with the solar heat gain coefficient. A 2:1 LSG ratio can be achieved with low-e coatings, meaning that the glass can allow twice as much visible light to pass into a room than heat.

Higher LSG ratios indicate that the window is more effectively separating the visible light from the solar radiation and blocking the heat-causing radiation from entering the space.

Glazing with the triple-silver low-e coating can offer very low solar heat gain coefficients, on clear glass, and exceptional LSG ratios, which means that the interior of the building is filling with daylight and not with heat from absorbed solar radiation.

DESIGN TIP

MATCH GLAZING PERFORMANCE METRICS TO PROJECT CLIMATE

Advancements in low-e coatings offer better management of solar heat gain and more aesthetic options in terms of the clarity, color and reflectivity of the glazing.

When selecting glazing for a project, designers often start with identifying the level of thermal performance necessary to meet applicable code requirements, either the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard 90.1 (ASHRAE 90.1) or an ASTM International Standard, which vary based on the location of the project.

As a general rule, energy codes require that projects in the south be outfitted with glazing that has a SHGC value of 0.25 or lower. This helps minimize the amount of solar radiation that will pass through the glass and into the interior, heating it up and taxing the HVAC system. In northern cities, like Chicago and New York, the codes allow for higher SHGC limits, often above 0.3, because buildings in these climates can benefit from passive heating that occurs when solar radiation enters a space and warms it up during the winter. In fact, the codes for these locations often stipulate the U-value of the glazing, putting the emphasis on minimizing heat loss, instead of preventing heat gain.

Triple-silver low-e coatings can offer designers the daylighting and thermal management solution that keeps solar heat gain low for projects in areas where the sun’s energy is more intense and minimizes heat loss through the IGU for projects in cooler climates.

SPECIFYING A BUILDING ENVELOPE THAT PERFORMS AS DESIGNED

One of the biggest challenges facing designers as they work to create buildings that are more energy efficient is the reality that there is often a difference between the modeled performance of the building design and the performance of the constructed building. To that end, green building programs are beginning to incorporate elements that require proof of performance once the building is occupied. While these accountability measures are applauded in the sustainable design community, they place another level of responsibility onto the design team that requires the selection of fail-proof or proven products that can withstand the certain degree of chaos and unpredictability that is common on a construction site and then perform as promised once installed.

The building envelope is a great example of an aspect of the constructed environment that can be designed to deliver the requisite level of thermal performance and then actually perform much worse.

To understand how this happens, consider a commercial building envelope constructed from traditional architectural precast concrete. In the design phase, the designer probably referenced the thermal requirements for the building as identified in the applicable energy code, either the International Energy Conservation Code (IECC) or ASHRAE Standard 90.1. While there are important nuances to the mandates of each code, there are similarities in how both IECC and ASHRAE approach defining a requisite thermal performance for a building envelope.

Both IECC and ASHRAE Standard 90.1 divide the United States into distinct climate zones, each with its own minimum thermal performance requirements.

The code sets specific insulation requirements for the thermal envelope, depending upon the project’s climate zone and the type of walls, whether they are concrete masonry walls, metal, or framed in metal or wood. It also identifies requirements for building thermal envelope opaque assemblies in terms of the acceptable U-factor. The designer specifies a building assembly that is compliant with the applicable code, meeting the prescriptive R-values and U-values, and selects the desired cladding.

During the construction phase, the building envelope, which consists of many disparate parts and pieces, is assembled layer by layer by different teams of workers. The frame is erected. Traditional precast architectural concrete panels, commonly 6 to 8 in.- thick, which will provide the exterior skin of

the building, are installed. The cavity is filled with insulation. The moisture and air barriers are installed.

Mistakes can be made. Gaps occur. Thermal bridging happens. The moisture barrier can be ripped or compromised. These mistakes affect how effectively the building envelope insulates the interior and how efficiently the building operates.

Designers today are looking for building envelope solutions that will perform as specified, reliably creating an efficient barrier against the exterior environment. Factory-built, factory-tested assemblies can eliminate much of the onsite variability that ultimately affects the thermal performance of the occupied building. Solutions like an architectural precast concrete cladding system, which contains the entire envelope system inside a monolithic, panelized unit, can offer designers the reliability they need in this next stage of sustainability, where built performance matters.

ARCHITECTURAL PRECAST CONCRETE © SlenderWall

CLADDING SYSTEM

An architectural precast concrete cladding system is a modularized building envelope solution that includes the façade, moisture/air barriers, insulation, and is even available with windows and interior framing.

The system features a lightweight 2-in. thick precast concrete panel that is fixed to a light gauge galvanized steel frame with stainless steel fasteners. The way that the exterior concrete face attaches to the frame creates a thermal air gap that is filled with factory-applied, closed-cell foam insulation. The panels weigh onethird the weight of the traditional architectural precast panels, which allows installation to be completed with smaller cranes. This compact and comprehensive building envelope solution also eliminates the need for multiple insulation and interior crews. The cladding system is easily installed upon the building frame and the interior face of the panel is equipped with galvanized steel studs that are ready for drywall, reducing construction schedules.

In terms of thermal performance, these architectural precast concrete cladding systems have been designed to meet current IECC thermal requirements in multiple climate zones. More specifically, this system can be specified in Zones 1 through 8, which makes it suitable for projects in Miami and the North Slope Borough in Alaska.

It is worth noting that manufacturers of building envelope assemblies, like the architectural precast concrete cladding system described in this article, have two code-compliant avenues available for determining the thermal performance of their assembly products. They can use a prescriptive method, which essentially employs calculations to arrive at the expected thermal performance of the solution, or they can test the assembly to attain accurate data on the heat transfer that occurs through the insulated structure in representative test conditions.

“The sustainability movement is moving toward greater degrees of transparency, so that designers have the best, most accurate information available to make their product and system selections,” explained Art Miles, president of Easi-Set WorldWide,

Designers of the LEED Gold New Orleans BioInnovation Center, Eskew+Dumez+Ripple and NBBJ, created the highperformance envelope with an architectural precast concrete cladding system.

a manufacturer of precast concrete. “We believe that designers are going to begin demanding performance data from third-party vendors to ensure the products they select can, in fact, perform as the manufacturers claim they can. We have had our architectural precast cladding system rigorously tested and openly share the tested results.”

The independent laboratory testing, mentioned

by Miles, was the American Society for Testing and Materials (ASTM) standard ASTM C1363-11 Standard Test Method for Thermal Performance of Building Materials and Envelope Assemblies by Means of a Hot Box Apparatus, during which several architectural precast concrete panels containing varying depths of different closed-cell foam insulations and different sized thermal gaps were subjected to different conditions in a hot box test. The test measures the transfer of heat across the assembly and determines the thermal performance in terms of R-values and U-values of a particular building envelope solution. During these tests, the architectural precast concrete cladding system proved to be an acceptable solution for projects located in climate zones 1 through 8, meaning it can be used on any U.S. project and in many areas of Canada.

Designers interested in knowing whether the stated R-value or U-value of a thermal performance solution is a calculated estimation, or a proven performance result, should ask manufacturers for more information.

REDUCE EMBODIED ENERGY IN DESIGNS

As sustainable design efforts have succeeded in reducing the energy consumption of buildings by improving the efficiency with which they operate, the community is turning its attention to reducing the energy consumed in the creation of the products and materials

that comprise the built structure. The term embodied energy refers to the energy consumed during the construction process and includes the consideration of the energy consumed during the extraction, processing and manufacturing of each product found within the finished building.

“We understand the dire negative implications associated with greenhouse gas emissions to the atmosphere, and we know that the construction and operation of buildings is a significant contributor to greenhouse gas emissions worldwide,” explains Brendan Owens, senior vice president at USGBC. “Building energy use still represents the largest piece of the greenhouse gas puzzle in buildings, but over the past 40 years the operational efficiency of buildings has improved dramatically. We are even seeing zero-energy building performance goals achieved. As building efficiency improves, the relative importance of the materials we use to construct buildings grows. We’ve introduced credits in LEED designed to help designers minimize another big piece of the total carbon footprint. These credits inform and incentivize the specification of materials that have lower greenhouse gas emissions profiles.”

SOLUTION

SPECIFY WOOD AND WOOD PRODUCTS

Trees, and the wood products derived from them, provide examples of the types of materials that can be used in building design and construction that offer low embodied energy values. In the report, Building with Wood: Proactive Climate Protection, author Dr. Jeff Howe explains, “Trees absorb carbon dioxide (CO2) and water (H20) and release oxygen (O2). The carbon absorbed is stored until the tree dies and decays or is burned in a wildfire, at which point the carbon is

released back into the atmosphere. Products made from wood continue to store carbon for as long as they exist. In fact, one-half the weight of wood is carbon.

This ability to store large quantities of carbon for long periods of time sets wood apart from, and provides a significant environmental advantage over, other building materials.”

Howe continues, “When wood products are manufactured, carbon emissions [or CO2 equivalent emissions] are typically less than zero, meaning that more carbon is contained within the wood itself than is released into the atmosphere in the course of its manufacture.” This is a rare and unusual characteristic for a building material to possess. Howe goes on to explain, “The energy required to manufacture wood products is generally about half as much as is contained in them. Consider a glued laminated timber [beam]. The process of harvesting and drying the raw material, then manufacturing the glulam, consumes less energy than that which has previously been absorbed into the product. And what’s more, trimmings and other scraps generated in converting round logs to timbers are used in making other wood products—particleboard, fiberboard and paper—or is used in generating fossil fuel-free energy. The products themselves, once they reach the end of their life cycle, can be recycled or used to generate energy.”

For proof, look at the Environmental Product Declaration (EPD) for various North American wood products released by the American Wood Council and verified by the Underwriters Laboratories Environment (ULE), an independent certifier of products and their sustainable qualities. An EPD is a document that provides standardized and objective information assessing the lifecycle environmental impact of a product. These EPDs support the claims made in Howe’s report by quantifying the Carbon Sequestered in Product at Manufacturing Gate as a negative (-) value. In other words, the amount of carbon emitted in the creation of a wood product, such as North American Laminated Veneer Lumber (LVL), —up to the point that the product has been manufactured and is ready for shipment, the portion of the life cycle referred to as cradle-to-gate—is negative. More carbon energy is contained within the wood product than has been emitted in the extraction and production of that product.

While the EPDs from the American Wood Council provide a collaborative and industry-wide summary, wood products manufacturers are also investing in generating EPDs that are specific to their product offering and processes. Grady Mulberry, President and CEO of Roseburg Forest Products explains, “We have developed third-party verified EPDs to provide the product-specific environmental information that specifiers and builders are starting to demand. They support the claim that wood products are durable, natural, renewable, and come from sustainably managed forests that capture carbon, making them among the most responsible building materials available today.

The EPDs we developed help us demonstrate that wood truly is a superior building product.”

In the U.S., wood is commonly used as the main construction material to build homes. “About 80% of housing units are primarily built of wood, providing millions of tons of carbon benefit, including both

Increasing the use of wood in commercial construction would have many positive environmental benefits.

Wood products store carbon for as long as they exist and have low embodied energy values.

carbon stored in wood itself and emissions avoided.”

The report by Howe states, “Increasing the use of wood in commercial, industrial, health care and government buildings would significantly reduce the climate change impact of building construction and increase carbon storage in the nation’s building stock.”

The report posited that “increasing wood use to the maximum extent feasible in multi-family housing, low-rise nonresidential construction and remodeling could result in a carbon benefit equal to about 21 million metric tons of CO2 annually; this would be the equivalent to taking 4.4 million automobiles off the road indefinitely.”

Innovations in wood products and new wood and mass timber technologies have expanded the role that wood products can play in a multi-family or commercial building project. The science of wood fibers, resin, and pressing allows wood products manufacturers to produce engineered products that are stronger and offer the enhanced performance characteristics necessary for these new applications.

Wood can be considered as an alternative to more traditional steel and concrete materials used for framing and offers several benefits to taller structures.

Mass timber components are natural insulators and offer impressive thermal performance to the building.

The strength-to-weight ratio of wood is consistent with steel, but it weighs less, reducing loads on the foundation, which can be critical during seismic events. In the case of a fire, large wood slabs have excellent fire resistance, charring on the outside and protecting the integrity of their inner structure.

According to USDA Secretary Tom Vilsack, “Wood may be one of the world’s oldest building materials, but it is now also one of the most advanced. Building stronger markets for innovative new wood products supports sustainable forestry, helps buffer and/or reduce greenhouse gas emissions, and puts rural America at the forefront of an emerging industry.”

the impact that those materials will have inside the built environment, as well as the ultimate end-of-lifecycle plan, whether a material will be destined for the dump or repurposed or recycled.

Shading is an important piece of any sustainably-designed project. It is a necessary safeguard that enables a building to provide that critical connection with the outdoors, providing views and access to daylight, while protecting occupants and building performance from the discomfort and energy waste that can occur from glare and solar heat gain. Understanding the basic material compositions of the majority of shading products in the market and comparing and contrasting how those materials perform in terms of view-through, dimensional stability, recyclability, and fire retardancy will help designers select a shading fabric that meets the sustainable demands of a project.

CHOOSE SUSTAINABLE SHADING FABRIC

A key theme in sustainable design today is that the material matters. It is no longer enough to have a building that performs efficiently and minimizes or eliminates unnecessary energy waste. Designers are being challenged to consider the energy that was used in the production of the materials found in the building and

SOLUTION

COMPARE DIFFERENT TYPES OF YARN

An overwhelming majority of the shading fabrics on the market are constructed from either a fiberglass or polyester yarn. Fiberglass is a fiber mainly produced from silica (sand) and includes limestone and soda ash. Composed of inorganic materials, fiberglass fabrics are unaffected by fungus or bacteria and are noncombustible. These glass fabrics also have a comparatively high melting point, which makes them much less susceptible to elongation than the other common yarn types. Elongation refers to the stretching and warping of a shade fabric that can occur when the shade is exposed to a level of heat or pressure that it cannot withstand. Fiberglass yarn does not elongate.

Polyester yarn is a synthetic, thermoplastic fiber derived from coal, air, water and petroleum. This material is more flexible than shade fabrics made from fiberglass and can be constructed from post-consumer recycled content, like water bottles. Unfortunately, the long chain molecular structure of the polymer material is prone to elongation and stretch and the fabric has a lower melting point, which can be ill-suited to the intense heat that can occur when direct sunlight hits the shade through the window. Polyester fabrics can offer a higher visible light transmission than other fabrics, which means that more light is allowed to pass through the fabric than is absorbed or reflected. This higher visible light transmission can assist designers in achieving higher levels of daylight on the interior.

There are 100% fiberglass and 100% polyester shade fabrics available. Another popular shading material uses fiberglass or polyester yarn as its core material and coats it with a polyvinyl chloride (PVC).

The PVC coating provides the color for the shade and improves the durability, fungal resistance, UV resistance, washability and fire-retardant characteristics demonstrated by the fabric.

The finer fiberglass yarns, which feature a greater number of smaller openings across the material, provide a crisper view through the material.

RECYCLABILITY

The type of yarn used in a fabric also determines the recyclability of the fabric. Solar shading fabrics manufactured from 100% fiberglass or 100% polyester are recyclable. Unfortunately, once the PVC coating is added to a fiberglass or polyester base yarn, the entire shade product is not recyclable.

FIRE RETARDANCY

Fabric flammability is an important performance characteristic to consider when selecting the right materials for a project. Certain types of projects have code-mandated performance criteria that must be

VIEW PRESERVATION

View preservation is one of the great advantages of choosing a solar shade over a blind because a solar shade still provides a view to the outdoors when it is pulled into the closed position. A blind product fully obstructs any view to the outdoors when deployed.

However, shades constructed from different yarn types provide a different level of view preservation.

Shade fabrics are often specified in terms of an openness factor. While different shade materials can, and do, offer the same openness factors (1%, 3%, 5%), the way the openness is distributed across the face of the material affects the type of view that a person can achieve through the fabric. Fiberglass core yarns tend to be finer than polyester corn yarns. When finer fabrics are woven together, the weave has a higher number of holes, or areas of openness, present per square-inch of fabric, than a weave of a thicker polyester core fabric. On average, there are 750 openings in one-square-inch of a fiberglass core material, and only 520 openings in one-square-inch of a polyester core material. The finer fiberglass yarns, which feature a greater number of smaller openings across the material, provide a crisper view through the material.

The concept is very similar to the number of pixels on a screen display. The higher number of pixels on a screen, the better its resolution.

It is common practice to specify a shade fabric based on its color and openness factor, but the composition of the material can make a material difference in the way the shade performs.

satisfied. Regardless of project type, selecting shading materials that will slow down the combustion of the fabric or self-extinguish helps to protect the people and property inside the building when a fire occurs.

Shading materials can be classified as either flame retardant or flame resistant. Flame-retardant materials are chemically treated and designed to slow down ignition or combustion. A 100% polyester fabric with a fire-retardant surface treatment is a common example of this type of material. These materials are so common, in fact, that the majority of window shade fabrics available on the market fit into this category.

Flame-resistant fabrics are made from materials that are inherently nonflammable and designed to self-extinguish. Woven from sand and limestone, 100% fiberglass materials are recognized as flame resistant.

In order to determine the performance of fabrics used as curtains, draperies and other window treatments, the National Fire Protection Assn. (NFPA) developed a test method to assess the propagation of flame across various textiles under specified fire conditions.

NFPA 701 is a fire-retardancy testing standard required by the International Building Code (IBC) for textiles used in public spaces such as schools, churches, auditoriums, theaters and commercial buildings. The standard is designed to evaluate textiles that will hang freely (e.g. roller shades). The test method exposes 10 individual samples of a specified size to a flame for 45 seconds. The weight loss of the fabric and the presence of a residual flame is measured. In order for a fabric to pass the NFPA 701 test, the total weight loss of the sample cannot exceed 40% and the residual flame cannot last longer than an average of two seconds.

Look for solar shades that are compliant with NFPA 701 to specify a material that will help protect life safety in the event of a fire.

It is common practice to specify a shade fabric based on its color and openness factor, without regard for the type of yarn with which the shade is woven, but the composition of the material can make a material difference in the way the shade performs once it is installed. In this era of sustainable design, where there is growing scrutiny on the actual performance of the product, understanding the impact that the type of yarn can make on project objectives like view preservation, fire safety and recyclability is important.

PREVENT PREMATURE PRODUCT FAILURES

In terms of practical application, the material matters, green or not, because a product must be able to withstand the conditions in which it is placed. Specifying products made of a material that is ill-equipped to weather its surroundings may lead to the premature failure of that product, reaching its end-of-lifecycle destination sooner than necessary. Specifying products that can sustain the hazards in their environment is a key consideration in sustainable design.

The restroom or locker room environment is a great example of a space that can pose a significant number of threats to a material. These areas are often high traffic, in constant use and there is a certain de facto rigor to the activities that take place there.

Exposure to germs and bacteria is a daily occurrence.

Vandalism is a real concern in many bathrooms, be it from graffiti or a rambunctious visiting team that just lost a big game. Finally,there is the constant presence of water, from handwashing and showering, to regular cleaning. The materials specified for the bathroom partition or washroom accessory therefore, must be able to contend with a lot.

SOLUTION

MATCH MATERIAL TO DEMANDS OF THE SPACE

There are five materials often selected for use in a bathroom space as either a bathroom partition or a washroom accessory, or both: steel (powder-coated or stainless); high-density polyethylene; plastic laminate; phenolic; and solid surface materials, such as marble and granite. Each has its own strengths and weaknesses that should be explored when determining which material best fits the specific type of bathroom or locker room being designed.

Powder-coated and stainless-steel partitions are often specified in bathrooms and locker rooms.

The powder-coated solutions are considered budget-friendly and available in a wide range of colors and finishes. Stainless-steel is more expensive and creates a higher-end aesthetic. Although powder-coated and stainless-steel partitions are quite common, very high humidity environments may undercut the longevity of the product’s usable life.

laminate sheet, which acts as the protective top layer, is tough, but can be damaged. While vandals may find it hard to scratch the surface, they may be able to delaminate the top sheet in standard plastic laminate with enough effort.

Phenolic materials have many qualities that make them a great fit for bathroom areas. They are impact resistant, which means phenolic bathroom partitions are very durable and are difficult to scratch. The phenolic material is also impervious to water, which makes it an optimal choice for showers, saunas and aquatic facilities, as the material is impenetrable to mildew, mold and odor. Phenolic bathroom partitions are available with a black core or can be created with the surface color integrated throughout the panel, like HDPE. From a coordinated design perspective, both bathroom partitions and washroom accessories have been made in the phenolic material, enabling specifiers to create a cohesive look throughout the space. It should be noted that, when selecting washroom accessories, it is important to pick products that have the appropriate capacity for the application.

Choose large capacity paper towel dispensers or soap dispensers for stadiums or airports to ensure that the supplies will last, even through the rush.

Solid surface materials, such as marble and granite, can also be used for bathroom partitions and urinal dividers. These materials are impervious to humidity and resistant to damage from water and cleaning chemicals. However, the use of these surfaces can be expensive, as both the materials and installation costs are much higher than the costs associated with buying and installing a powder-coated, stainless steel, HDPE, plastic laminate, or phenolic partition.

Beyond choosing a material that can perform in the bathroom or locker room space, mainstream sustainability considerations now encourage designers to seek materials that also feature a low embodied energy, recycled content, or the quality of being built from rapidly renewable resources and low-VOC emissions that have been verified.

Steel products designed for use in a bathroom have often been engineered for rust and corrosion resistance. A powder coating on galvannealed steel improves the corrosion resistance of the surface. Quality stainless-steel products (Type 304) incorporate a mix of elements that enhance corrosion resistance.

For example, while most stainless-steel alloys contain some amount of iron, which easily oxidizes to form rust, they also contain a high percentage of chromium, which creates a protective layer on the metal surface and resists corrosion of the material.

Powder-coated and stainless-steel bathroom partitions and washroom accessories are also susceptible to vandalism. The paint can be scratched off a powder-coated steel product, which will require the surface to be repainted in order to fix the damage.

While stainless steel surfaces can be scratched, they can be buffed to remove the markings. Both types of steel can be dented or dinged with force. In areas that must withstand a rowdier crowd, like opposing team locker rooms in high schools and universities, consider specifying a higher gauge stainless steel for washroom accessories. Some manufacturers offer 16-gauge stainless steel, which is the thickest, most-robust stainless-steel material available in these products.

High-density polyethylene (HDPE) is a solid plastic material that is well suited to deal with the hazards of bathroom dwelling. With HDPE, the color is physically integrated throughout the material, not added on top of it at a later stage as a coating or laminate. As a result, bathroom partitions made from HDPE will never delaminate or need repainting.

The non-porous surface is incredibly strong and impermeable, which enables HDPE bathroom partitions to resist mildew, mold, corrosion, dents, scratches and graffiti. These durable surfaces cannot be dinged or dented easily. Scratches are less noticeable, because the color is homogeneous throughout the partition, and easily repaired. Graffiti wipes off easily with most non-abrasive cleaners.

Plastic laminate toilet partitions have a rigid, decorative outer layer, which is applied to a substrate typically made of particleboard. If moisture seeps through the black seams caused by standard edge banding, this particleboard can expand and warp causing the top sheet to delaminate from the core. One manufacturer, however, offers plastic laminate partitions without the standard black seams, by engineering a unique edge banding system that fuses with the substrate to create a seamless beveled profile. ASTM tests confirm this upgrade has an increased resistance to moisture and humidity, providing more than three times greater durability than standard plastic laminate partitions.

Designers should avoid using standard plastic laminate partitions in an indoor swimming area or natatorium, because the material will not withstand the continued exposure to the moisture and chemicals in the air. In terms of durability, the plastic

partitions can be provided with up to 100% post-consumer recycled content and up to 33% post-industrial recycled content. The make-up of products made from phenolic materials is documented as containing an impressive 67% of rapidly renewable materials; phenolic materials that are color-invasive have earned GREENGUARD certifications for achieving low-VOC emissions.

There are additional considerations for bathroom design that should be made, although they currently fall outside the definition of sustainable design. Occupant comfort is a key piece of the sustainable design algorithm. To that end, many schools have opted to incorporate high-privacy bathroom partitions, even though they are currently outside the regulations stipulated in the Americans with Disabilities Act (ADA), or the IBC, or a green building rating system, because they improve the comfort of people using the restroom. A high-privacy restroom partition eliminates sightlines into the occupied stall and makes it more difficult for people to peek under the door or over the walls. This singular feature may not make a bathroom operate more efficiently, but it can have a marked improvement on the comfort of the people using the space.

In summary, the market has reached the next era of sustainable design. Success in the marketplace further reduces the carbon footprint of a project and helps to maintain the momentum of this movement.

last detail: architectural leader

Exporting ‘Community as Strategy’ In a sort of public-private team up, KI and IIDA are “on tour” discussing the subject of community with local architects—a top issue in the industry, and one that’s contingent upon choices made.

Partnering with the Commercial Interiors Design Assn. (IIDA), furniture manufacturer KI is helping launch a series of architectural discussions across the country. The first “Community as Strategy” event recently took place in Chicago, and the next one is coming up July 10, in Washington D.C.; future events are planned for New York, Boston and San Francisco. A sort of series “pre-launch” began in St. Louis, where IIDA Executive VP and CEO Cheryl Durst moderated a panel, which included Aimee Rowbottom, director of architecture and interiors at Jacobs, among others. In setting the tone for the panels, KI’s VP of A&D marketing, Deborah Breunig, interviewed Durst and Rowbottom for a blog previewing the discussions. A road warrior, Breunig noted she often finds herself in long conversations with people waiting for their flights in airports.

While it may seem a bit

odd to be having long conversations with total strangers, Durst pointed out, it’s really not, as everyone is looking for a connection point.

“Community is one of the top issues people in the profession are talking about in 2019,” says Durst.

who come into them.

“Over the past couple of years, there’s more emphasis on providing meeting spaces. That’s reflected in data we’ve collected showing a 20% increase in places where people can connect with each other,” says Rowbottom.

In speaking with Rowbottom in more detail (some of her Q&A is included below), she asked the designer why community as strategy is important. “It’s a lot about choice, which is so integral to wellbeing. If users feel in control—that they can go to alternate locations or they are part of the decision-making process—they’re going to be happier and have a sense of wellbeing about themselves. That overlays itself on their experience with the company.”

When asked for an example where these design principles had measurable results, Rowbottom pointed out a project Jacobs did for a healthcare client, where they had need to increase space efficiency and flexibility.

After working to deliver a solution, the firm did a post-occupancy evalu-

She adds that spaces have to reflect what a business or organization is trying to do, but be flexible enough to change with the people

ation, which showed, in fact, the improvements did have a positive impact on work and wellness, along with space efficiency. “There was a 17% increase in space efficiency. But there was also a 46% increase for collaboration, a 35% increase in focus and a 32% increase in socialization. All by having choice-based design.”

Aimee Rowbottom, Director of Architecture and Interiors, Jacobs, St. Louis, was one of the fi rst participants in a collective discussion of architects focusing on community.

BREUNIG:

That goes hand in hand with the textiles. Some environments have become more casual with people bringing coffee, food and items that can cause dirt, debris and destruction to a piece of furniture.

ROWBOTTOM:

We’re seeing our textile manufacturers coming up with more and more patterns and weaves. Stain-blocking properties are being integrated in different ways, so we have more options in what we offer clients.

BREUNIG:

BREUNIG:

How important is involvement with the manufacturing sector—from lighting, to flooring, to furniture—to creating connected work and learning spaces?

People want community spaces to feel like home.

What options are available to designers?

ROWBOTTOM:

If there’s a certain look and feel that’s desired as you’re creating certain spaces, our designers need to reach out to our manufacturer and vendor base. That can help them understand available products that may have a similar look and feel that can meet the performance and safety criteria.

Vendors may offer up different options. Or, they may be able to offer a tweak or a change to a product to create the mood or vignette for which the designer is looking.

ROWBOTTOM:

Having a dialogue with manufacturers is key as these bigger ideas are synthesizing in the design process. I don’t know that it’s specifically product driven. It may be a series of discussions about how products are paired together, or how they are placed within a space, that helps provide some interesting opportunities for arranging space and providing choice.
