Deep Energy Deep Dive If you aren’t aware of the New Buildings Institute (NBI), you should be. The organization offers a tremendous amount of resources for those zeroed in on reducing the energy and carbon footprint of buildings. The group also keeps a running list of both certified, and “emerging,” net-zero projects across the country and Canada. Further, they’ve recently upgraded their database, which now allows designers seeking metrics for backing up net-zero and deep-energy pitches, a tool that allows search and sort by state, region, project type, market, size, etc.

As it stands today, the grand total of  projects is

It is critical to evaluate technology not by NZE itself, but rather as the key drivers for NZE: energy load shaping and GHG reduction.

580—about a hundred more than noted in 2018. In the 2019 report, analysis included a look at the top technologies and products allowing  facilities to achieve such impressive results: super robust envelopes, alternative , including heat pumps,  and , and finally, daylight access and controls, in concert with solar control and shading.

A recent webinar announced the new list and database tool, as well as other industry insights. For example, Clay Nessler of Johnson Controls, included highlights of his company’s annual owners’ survey, and their inclinations toward improvements planned for 2019. Fire/life-safety systems, security, and overall building management control technology were the top three, but rounding out the top five planned improvements were upgraded lighting systems (39%), and the installation of “smart” building equipment (33%).

That said, to give readers an injection of market intelligence to aid in making 2030 more of a reality, we’re presenting a special lighting section this issue, courtesy of our sister publication, Architectural SSL, that highlights key illumination considerations in architecture today, including controls and human centric-factors. We’ll also zoom in on lighting’s role in a fairly major architectural consideration— wayfinding. And, as we did in May, we’ll continue our integration of net zero concepts and practices.

But back to , and its current research, the group, at the behest of the California Energy Commission, was also part of a team that conducted a Gap Analysis for Zero-Net Energy (ZNE) Buildings. They identified high potential technologies, along with development, demonstration and deployment challenges.

1. While technology does not pose the biggest challenge to achieving ,  said it is a significant solution. Even though stakeholders ranked tech as the fourth lowest out of 16 challenge areas, they ranked it the second-most significant solution in the “silver bullet” tool kit.

2. As far as building systems, the focus needs to be on control tech, renewables and grid management.

Therefore, research gaps should address strategies that support demand response and smart control.

3. The emergence of controls with embedded intelligence and predictive analytics, say the researchers, enable buildings to schedule and balance load to minimize grid impact. Furthermore, renewable generation can align with demand to achieve grid harmonization with adoption of both electrical and thermal energy storage technologies.

4. The most prevalent research gap for technologies involved a lack of demonstrations and pilots.

5. Finally, to establish the relative tech research priority, the researchers noted it is critical to evaluate them in their effectiveness at addressing not  by itself, but rather as the key drivers for : energy, load shaping and  reduction.

Renewable Energy and Clean Power

Carbon-Free Energy by 2050: Have We Reached a Tipping Point?

In 1999, when I started at , it wasn’t the Smart Electric Power Alliance: it was the Utility PhotoVoltaic Group before becoming the Solar Electric Power Assn. (version 1.0 of the  acronym) in 2000. At the time, there was no meaningful grid-connected solar industry in the U.S., with just a handful of players doing demonstration projects supported by grant funding. A 50kW solar project was considered massive in size, and the average cost for a residential system was $10 per watt. Renewable energy didn’t even make it into the U.S. Energy Information Administration’s () pie chart for U.S. electricity generation sources. Al Gore’s “An Inconvenient Truth” hadn’t yet put climate change into the public spotlight.

Little by little, all those things have changed.

Large-scale solar and wind are now the lowest-cost resources in many states. Energy storage is becoming a viable option. Technology advancements are allowing customers to take control of their own electricity supply and demand. The overall U.S. electricity generation portfolio has become significantly cleaner, with coal dropping to 27% and renewables increasing to almost 20% in 2018, with continued rapid growth on the horizon.

The road won’t be easy, and it will take the collective effort of stakeholders globally to be successful.

Of all the changes and industry trends over the past two decades, the most significant is one we are witnessing today: voluntary utility commitments to get to 100% clean or carbon-free energy within the next two-and-a-half to three decades.

Many states, municipalities, corporations and other entities have also made similar pledges. Voluntary commitments from investor-owned utilities in vertically integrated states, in particular, are the real indicators that this transition is happening—and is about to accelerate. It’s the tipping point we have been anticipating since I entered the industry in 1999.

Xcel Energy, who recently announced plans to become carbon-free by 2050, recently released a report detailing how they closely examined key climate reports and worked with stakeholders to determine how best to align their company goals with those of the Paris Climate Agreement. Xcel’s commitment requires them to add thousands of MWs of renewables, pursue strategic electrification

and make critical investments in grid infrastructure.

In Idaho, only three years ago, President and  Darrel Anderson told stockholders he didn’t believe Idaho Power would ever be able to go to 100% clean power. However, this past March, Anderson announced a plan to get to 100% carbon-free energy by 2045, with the first of nine coal and gas plants closing at the end of this year.

The same is true for MidAmerican Energy. There are no current state mandates in Iowa for carbonfree energy, nothing requiring a change in energy sources. Instead, 91% of customers polled in the service territory said that it’s important for energy to be produced from carbon-free sources, and armed with that customer mandate, MidAmerican is bringing 2,591  of wind energy online in the next few years to reach 100% clean energy sources.

Historically, the responsibility of reaching a carbon-free future fell more on the shoulders of state and federal regulators and government, but the electric power industry is making commitments to address climate change and customer concerns.

As part of ’s continuous evolution to ensure we can provide the most valuable thought leadership, unbiased information and practical solutions to the electric power industry, our board of directors recently adopted a bold new vision for the organiza-

tion: a carbon-free energy system by 2050. ’s role is to facilitate a smart transition to a clean and modern grid.  is leading the way in four areas of focus, what we call “ Pathways”: utility business models, regulatory innovation, grid integration and transportation electrification.

As we conduct our work on these pathways, we are operating under the following guiding principles:  Significant increases in clean energy, generated from existing and new technologies, are needed.  The future will be a diverse mix of large-scale generation, distributed energy resources (), energy efficiency and enabling technologies.  Reductions in carbon emissions will occur as the transportation, building and industry sectors become more electrified.  Investments in the transmission and distribution system are foundational to achieving a carbon-free energy future.  Diverse business models supporting carbon reduction will be deployed by utilities and other providers that account for geographic, business and policy differences.

Changes to the power sector need to evolve in a manner that is secure, reliable and affordable.

Success will require a collaborative process and engagement with stakeholders and customers.

Best Practices in Resiliency ››

High-Performance Buildings

Resiliency and the New Built Environment Editor’s Note: Following is the conclusion of a white paper, “Building Resilience,” commissioned by Danfoss and written by Penn State professors: James Freihaut, Sez Atamturktur and Gregory Pavlak.

The consequences of resilience failure are far too tragic, and now far too frequent, to treat it as a second or third tier issue. As a result, transdisciplinary efforts are beginning to emerge, with designers, builders, engineers, financiers, utilities, scientists, urban administrations, and others working toward a resilience-based definition of high performance, and to deploy a new conception of the built environment.

Meeting the challenge will require clarity about options and impacts, and engagement from a full range of stakeholders. Since the 2017 Danfoss High Performance report first highlighted the initiative, the U.N. Economic Commission for Europe () has adopted the Framework Guidelines for Energy

Whether government, the private sector and great swaths of society can rise to such a unique situation may be the great question of the 21st century.

Efficiency Standards in Buildings and has begun to assemble collaboration among stakeholders. In 2018, ’s High Performance Building Initiative () was well underway, with the mission of radically cutting building-related carbon emissions, while improving quality of life within buildings and the built environment. In brief, they are working to decouple progress from carbon in order to achieve an overarching and genuine sustainable development.

Resilience is integral to the  goal and to the energy equation more generally. It is also an increasingly compelling priority for urban communities, and because more urgent, it may well be a theme around which wider support and engagement can be effectively built. The  is itself positioned for substantial impact in the 56  countries, and even globally. It is an established, impact-oriented platform with a mandate to advance the 2030 Agenda through action on energy and buildings in the field and on the ground. Incorporating the resilience challenge explicitly into the  operating agenda can only serve to advance the two interrelated causes. Doing so will facilitate focus on important actionable priorities by the overall resilience and sustainability community or the relevant experts, and the opportunity to do so should be seized and leveraged.

Specific resilience-related goals include:

On the Finance Front The development of new valuation models better reflecting and supporting the real value of resilient buildings in a resilient built environment, linked to durability, construction and maintenance costs, extended life-cycle costing, insurability and capacity to hold value.  Establishment of recognized community scale resilience risk assessment and evaluation criteria for use in determining municipal creditworthiness.  Development of routinized methodologies for holding municipalities financially accountable in financial markets for their true and discernible risk profile. 

For Building Engineers Prioritization of application of new digitalization, data collection and analysis, and system and subsystem controls for knowledge-based, real-time decision making.  Development of in-the-field performance metrics and data collection in both post- and duringextreme event time frames.  Strengthened application of IOT-building interface technologies.  Application of available information and cyber decision-making systems, with feedback loop to research agenda. 

DANFOSS HIGHPERFORMANCE REPORT

Since the 2017 Danfoss report first highlighted the resiliency initiative, the  has adopted the energy efficiency standards framework, and has begun to assemble collaboration among stakeholders— researchers, educators, designers, engineers, builders, manufacturers, policy makers and more.

PV in More Places The morning I penned this piece I was having a bit of an existential crisis, so I just sat on a bench and decided to “be.” Sitting there still and quiet, I observed a house I must have walked by thousands of times, but until that moment, had never noticed it had PV on the roof... So taking this respite to think a bit, I was inspired to make note of some things happening in the world of renewables. First, according to the Federal Energy Regulatory Commission’s latest monthly Energy Infrastructure Update report, as analyzed by the nonprofit, the Sun Day Campaign, electrical generating capacity by renewable sources edged past coal in the United States for the first time—at least through April 30. According to the  report, 2019, to date, has seen the addition of 1545  of new wind capacity, 1473  of new solar capacity and 29  of new hydropower. At the same time, coal’s share dropped to 21.55%, down from 23.04% a year ago. Furthermore, according to the Smart Electric Power Alliance (be sure to read more in the On Spec, p. 12), the solar market, in 2018, grew by 20%, with California and Texas leading the way. ’s latest data also revealed that, on average, U.S. renewable energy capacity has been adding 23.04% a percentage point each year. Now it’s impor21.55% tant to understand that % of Total Generating Capacity of Coal capacity is not the same 2018 2019 as actual generation.

The Energy Information Administration reports for 2018 that renewables accounted for a little more than 17.6% of total electrical generation, with coal’s share at 27.2%. In addition, he noted that  only reports data for utility-scale facilities, so these reports don’t reflect distributed renewables capacity such as rooftop solar.

Here’s where I want to give a special plug to one of the products we’re featuring in this section—Pvilion, and their -integrated -coated fabric tech. I spoke with the Brooklyn-based company’s  Colin Toughey, about the tech which takes  generation way beyond the standard rooftop panel. Working with the likes of Behnisch Architken and KieranTimberlake—the latter who initially wanted the system as part of their façade for the U.S. Embassy in London, and the former using it for a net-zero project in Boston—the company not only provides product, but design-assist and design-build services to make the concepts you see on the opposite page, come to be; or they simply provide stylish, yet functional shade structures that also produce power. Seems like a winwin to me.

Demand for design services in May remained essentially flat in comparison to the previous month. AIA’s Architecture Billings Index score for May showed a small increase in design services at 50.2, which is slightly down from 50.5 in April.

“The last four consecutive months, firm billings have either decreased or been flat, the longest period of that level of sustained softness since 2012,” said AIA Chief Economist Kermit Baker. “While both inquiries into new projects and the value of new design contracts remained positive, they both softened in May, another sign the amount of pending work in the pipeline at firms may be starting to stabilize.”

Acoustics

ACOUSTICS

Slamming the Door on Noise Doors manufacturer Masonite recently hosted an event on acoustics, which included a tour of its new West Chicago sound lab—one of only 12 such facilities in the country. The event also involved an industry panel breaking down pressing issues on the acoustics front. Participating were Michelle Osburn, a workplace strategy senior consultant with the Chicago office of Perkins+Will; Ryan Biziorek, the acoustics, audio-visual, and theatre consulting leader for Arup; trend consultant Claire Walsh, whose clients include Levis; Ethan Bourdeau, associate,

Osburn got things rolling, noting the open office phenomenon, which has led to many noise issues, began with the desire to bring more natural light—it represented the trend toward thinking more about people. Thus, in context of a human experience, she says, designers and architects need to start thinking, exactly, as to how different people work in a space and

what their roles are, and really start designing around these ideas.

Of course, this is a big cultural change for both designers and clients in having to really think hard about individuals, or at least classifications of workers.

Both Biziorek and LoVerde couldn’t emphasize enough the importance of addressing acoustics early in the design phase, particularly to mitigate speech propagation.

Arup’s Chicago office, in fact, has its own sound facility where they run clients through a series of “noises” that helps establish what is, and what’s not acceptable.

Such an option, says Biziorek, really comes to bear when facing the budget axe, as it helps prove, quiet, or mitigated sounds levels in spaces, are not a “luxury.”

LoVerde noted it also helps to take clients to projects where mitigating measures have been instituted.

For example, in the  area, he points clients to a multifamily project, where year after year, they have been able to track noise reduction and resultant complaints. “Acoustics doesn’t have to be expensive, just well thought out,” said LoVerde.

CONSIDERATIONS

With the  standard gaining traction, ’s Bourdeau warned designers not to be too myopic on specific certifications, as there is no cookie-cutter prescriptive method.

Also, he urged manufacturers to deliver more in situ vs. lab results for sound measurement, as there is a world of difference.

ADAPTIVE REUSE

Cleveland’s Standard Building The 20-story terracotta Standard Building has graced the cityscape of downtown Cleveland, Ohio, since 1924. Constructed by The Brotherhood of Locomotive Engineers—the oldest union in the nation—the Standard Building was their Cooperative National Bank Building.

Throughout most of its long life, the building functioned as an office building in a prime downtown location. Today, the urban trend of office-to-apartment conversions is transforming the business districts of many cities, including Cleveland’s. Weston, the building’s owners, knew the time was right to capitalize on that trend and convert the Standard Building into a completely renovated, 281-unit luxury apartment building.

Part of its renovation features a revamped piping system for both potable water and  watersource heat pump piping for the building’s new comfort system, which includes 290 WaterFurnace water-source heat pumps.

For Lee Tucker, project manager, Marous Brothers Construction, the company’s Design/Assist approach at the Standard Building was to “go with what you know.”

“We explored the use of Aquatherm with the mechanical engineer and visited another project of similar size and interviewed the employees of the installing mechanical contractor. After research, we felt comfortable with using Aquatherm,” says Tucker.

Ultimately, more than 8,300 ft. of Aquatherm polypropylene-random (-) piping—ranging from 0.75 in. to 12 in.—and more than 800 fittings were used on this project.

The Standard Building project incorporates Aquatherm Green Pipe for the building’s potable water applications and Aquatherm Blue Pipe for its  applications. It offers longevity and consistent performance, and is hydrophobic, which means it will not corrode or scale over time.

Part of the Standard Building’s renovation features a revamped piping system for both potable water and heat pump piping.

Aquatherm Green Pipe is chemically inert and is potable water ( 61) and food safety ( 51) rated.

It will not leach, corrode or erode. In addition, the heat fusion method of joining Aquatherm pipe does not create any VOCs and does not introduce any lead or other toxic materials into the system. Nor does it involve and open flame or hot work permit unlike welding carbon steel. www.aquatherm.com — Circle

HOSPITALITY

Todd Baker, owner of TJ Mechanical, Plumbing and Heating in Litchfield County, Conn., has been plumbing Texas Roadhouse locations for the past five years in several states, including Connecticut, New York and Pennsylvania. The blueprint and footprint for most of the restaurants is largely the same, aside from some being reversed in layout from the others. After seven restaurants, Baker has things down to an art.

“I love that with ProPress I can prefab a lot of the stuff and because I’ve done so many, it goes even more quickly,” he said. “Everything here really comes down to timing. These builds are four months from shovel in the ground to opening, so every day counts. The owners appreciate [the speed of Viega connections], because they give you a certain number of days for underground rough-in and if you’re done earlier, then other contractors can get in earlier.”

When Baker began working on the restaurant projects, he said the only thing specified was that copper should be used for main water lines, the hot and cold and recirculation lines and in the boiler rooms. He chose to use ProPress, having prior experience with Viega products.

Shedding Some Light on the State of Building Illumination I don’t envy architects today. The combination of new technology and continuous overall building system innovations, makes it difficult to stay on top of things. Indeed, it’s hard enough to master the delivery of buildings and spaces that provide both energy efficiency and occupant comfort, and add new tech to the mix.

This, of course, is the challenge, in that many owners and clients are excited about big buzz words in the industry, particularly those associated with lighting: IOT, POE, LiFi, color tuning and human-centric lighting, etc.

On top of all this, the promise of LED has finally come to fruition, in not just energy-efficient and longer-lasting fixtures, but slim, even sculptural, luminaires, that in some cases, are works of art, and certainly can become the focal point of a given space. I have to look no further than one of the winners in this year’s International Assn. of Lighting Designers annual awards, and Scotland’s parliament. Already a beautiful wood-clad space, the chamber really comes alive now that utilitarian high-bay metalhalide fixtures have been replaced by aethereal things of beauty.

Meixi Urban Helix Shines As noted, IALD fetes projects from around the world. This year was no exception, and one of its Awards of Excellence went to the Office for Visual Interaction for the illumination of KSP Jürgen Engel Architekten’s Meixi Urban Helix in Changsha,

China. Like a stream of water, a continuous, uniform band of light wraps around the curved structure. The primary feature of the design is the glowing, infinite gesture of light that flows through the outer spiral of the building. The theme is

further emphasized by all the building’s other structural elements kept dark in contrast.

Concealed linear LED cove uplights illuminate the ramp canopy to create this spiraling ribbon. Visual depth stems from  capable luminaires that are

adjusted to distinguish the outer ramp surface from the inner surface.

Radiant in-grade lines also replicate the paving pattern that begins at the center of the helix.

Concealed step lights, and under-bench lighting, accent the stage and steps.

Marker Lights

Miniature in-grade LED uplights highlight the edge of the vertical structural elements, generating the image of a spiraling ribbon, another fluid design element.

On the inner ramp’s perimeter, miniature marker lights sparkle and guide visitors up and down the helix. Because of their low-level illumination, they do not disrupt the panoramic nighttime views for visitors.

HOSPITALITY

More Heavenly Dining Architecture and lighting come together to make dining in Toronto’s Union Station a more memorable experience.

Blending functional lighting into extraordinary architectural visions, can be a challenge. Such was the case at Toronto’s Union Station. Opened in 1927, the classically inspired building has been undergoing a phased multi-million renovation that includes the retail and food service sectors, and, of course, lighting.

A prime example of the renovation work is the Food Court, which opened in Fall 2018. Lighting designers Lightemotion joined the team of consultants charged with making the underground space into a stylish dining environment. With Dialog Design, Partisans, and GH+A Design, Lightemotion developed a program

that sought to avoid the “…uniform, uninspiring effect that is so often the situation found in traditional food halls,” according to François Roupinian, president of Lightemotion. The Food Court’s built-in market reach includes Union Station’s 250,000 weekday train and bus commuters, plus the , an indoor walkway system connecting adjacent buildings as well as the Air Canada Centre sports facility. To counter the image of a below-grade placement, Roupinian combined a functional and decorative overhead lighting system. For general light, the Sistemalux Faretto, small 3000K fixture is concealed in architectural ele-

ments. Suspended from the black painted ceiling are a total of more than 350 circular pods of two sizes, producing a cloud-like covering that floats above diners. Contained in 61 of the smaller pods are 2700K Color Kinetics eW Burst Powercore lamps; in 290 of the larger clouds are Color Kinetics ColorBurst Burst Powercore gen2 .

To balance the Food Court’s illumination with the time of day, is the Philips’ Light system manager, fitted with a special lens to diffuse the light.

Impact of Contemporary Fixtures

LIGHTING RETROFIT

Another outstanding project from this year’s batch of  awards was the lighting design for the Scottish Parliament Debating Chamber in Edinburgh. By  |  Lighting Design, the soft light from new bespoke  fixtures lends a healthy glow to parliamentarians. Judges called these fixtures a “technically brilliant solution” as how to light a room that functions effectively as a  studio and an accessible public space. The first step was eliminating the old metal-halide lights as they were expensive, difficult to maintain and obsolete. New  cameras require upgraded lighting to meet broadcasting standards. With a mere six weeks to develop and install the lighting design,  completed multiple site trials and time-lapse daylight studies to determine that the best solution, and one that would honor Enric Miralles’ original architecture, was a custom suspended luminaire. The design integrates suspensions and concealed wiring into the complex ceiling structure. The new  arrays have custom aluminum extrusion, bespoke precision turning, multi-axis adjustment, acrylic design, stringent output targets, individual controllability, deep dim-

ming,  broadcast compatibility and an extended lifetime. Based on where current members of parliament are seated, as well as glazing studies of the windows and considerations of where fixed louvres can be placed, a diagram was created to manage the placement of the  arrays. Supplemental spotlights serve for front fill as needed. The entire system is controlled through  controls, which saves 60% on energy over the previous scheme.

Balancing Daylight and Electric Lighting

PUBLIC & CULTURAL

PRODUCT

Art of Architectural Illumination Canada’s “address” for photographic and media art: Polygon Gallery in the Port of North Vancouver.

Daylighting and daylight harvesting have certainly become de rigueur. Patkau Architects understood this clearly in creating the striking two-floor Polygon Gallery which is capped with a saw-tooth roof. The gallery is situated in an exposed location directly on the waterfront, on a newly created plaza at Lower Lonsdale’s harbor quay.

The gallery shows a wide spectrum of Canadian contemporary art with a focus on photography and media art within the context of historical and international exhibits. The architects designed the two largest exhibition rooms on the upper floor to be airy and spacious; they receive daylight exclusively through northern-facing skylights, ensuring glarefree illumination of the spaces during the day without hard shadows. To keep the difference between daylight and artificial light as low as possible, the lighting designers opted for   lighting tools with a neutral white 4000K color. In the Polygon Gallery, the luminaires demonstrate their ability to ideally meet the most varied of lighting requirements within an art context, with uniform, glare-free general lighting on the one hand, and crisp accentuation of the exhibits on the other.

The horizontal steel girders below the saw-tooth roofs accommodate a flush-mounted track system on which Light Board spotlights and lens wallwashers have been mounted. Thanks to simple repositioning, these fixtures can be flexibly, and precisely, modified to meet the needs of specific exhibitions.

The orientation of the luminaires pays homage to the so-called “museum angle,” considered ideal for the illumination of art: the 30-degree angle of incidence avoids glare for observers that might be caused by reflections on paintings, photo works or media art.

The convenient adjustability, the innovative lighting technology and the simple linear design of Light Board completely convinced the lighting designers.

The control gear is integrated into the flat housing of the luminaires; the luminaires appear completely uniform and identical in construction even when fitted with different lenses and are also visually discreet within the overall design of exhibition spaces.

The architects underlined the contrast between the transparently-designed ground floor and the closed upper floor via their selection of different  lighting tools. In the large glazed ground floor, where the entrance area with reception, shop and lobby café merge, individual exhibits are crisply illuminated with Pollux contour spotlights. In this way the art works set themselves apart from the sales areas and draw attention to the actual exhibitions on the upper floor.

Inside the Tech

SMART DRIVERS

Driven to Success?

Back to the floor of Lightfair, the big buzzwords surrounding color tuning, human-centric lighting and “smart” lighting, abounded in full force. But before going all in on the latest lighting tech, perhaps, an old-fashioned focus on blocking and tackling illumination basics is a strategy that shouldn’t be underestimated.

LED is a no-brainer, but understanding the nuances of the tech is not so obvious. Take for example, lifetime and warranties. According to Jeff Gatzow,  of OptecLED, whose company focuses on delivering quality, controllable and economical exterior lighting to municipalities, what end-users seek is reliability and ease of maintenance burdens. True lifetime of products, therefore, should be fore of mind. Right now, Gatzow says there’s a big push in the industry to offer 10-year warranties on fixtures. While, indeed, major components—LEDs, housings, and optics—may have few issues over the life of the average fixture, power-related componentry has always been a weak link in anything electronic; in the case of LED, it’s the driver—the power device which has replaced ballasts—that is susceptible to failure. In LED’s early days, talk of fixtures lasting 100,000 hours was common. But now, with many fixtures having been in place for

some time, the industry is finding its not hitting those early projections. “We need new and better drivers—you can’t give a 10-year warranty, and then have a driver that’s only going to last five years,” says the manufacturer.

“Smart” drivers are also at the heart of greater fixture controllability, notably for color tuning and other “Big Data”-related desires. One driver called out

To remedy glare, manufacturers need to develop luminaires that remove the point light source from the line of sight, making the illumination more comfortable. at LFI, was that of Acuity brand, EldoLED, which won an Innovation Award for its 75W LED driver product family. The fully programmable driver family is capable of dim-to-0.1%, dim-to-warm, and tunable white performance. All 75W drivers are UL Class P listed.

Control options include 0-10V and DALI-2.

Another notable driver on the show floor belonged to OSRAM Digital, specifically, its Tunable White System. It’s based on DALI-2 designed for human-centric lighting applications. It can be

used as part of a connected solution that communicates via DALI-2 or as a standalone system. Lutron, too, with its new  system, gave show visitors a glimpse into a fully tunable office of the future. The system, the company believes, reflects the importance of biophilia, a human connection to nature; and incorporating the Internet of Things with smart technology to allow people to manage their environment with a variety of personalized control. “The concept of human centric lighting is about creating more comfortable and engaging environments for people. With this approach, Lutron puts the benefits of human centric lighting at the core of any discussion about lighting control and technology,” says Scott Hanna, Lutron senior vice president.

And lest we forget tunable fixtures, one that particularly caught my eye was USAI’s Incline for Sloped Ceilings. Most lighting systems are designed for leveled surfaces, and oftentimes cannot deliver the specific needs of an inclined surface. These fixtures, however, achieve high-quality, precision recessed lighting at angles up to 45 degrees; they are available for the BeveLED Mini and BeveLED 2.2 families, and can be equipped with USAI’s Warm Glow Dimming and Color Select tunable white technology.

REDUCES GLARE

At Lightfair, Lutron launched its HXL platform to support human centric lighting, which according to the company, should promote comfort, enable enhanced well-being, and foster engagement. HXL combines four elements: quality light, natural light, connection to the outdoors and adaptive and personalized control. The system’s approach for addressing natural light, of course, is a combination that maximizes daylight with dynamic shading solutions, while also incorporating color tuning via its Ketra line. The company’s office of the future demo, which took visitors through the changing light in the course of a typical work day, was impressive.

The OLPG1 addresses the common problem of glare with a flat light guide that removes LEDs from the line of sight without compromising luminaire efficacy or distribution performance.

Featuring a circular housing to eliminate alignment issues and work effectively in low-clearance garages, it produces up to 16,900 lumens at 130 W. A simplified quick-connect mounting bracket for seamless surface or stem-mount installation.

It’s tapered shape deters bird nesting and reduces cleaning and maintenance costs. The all-aluminum, pressure die-cast design offers durability and excellent thermal dissipation.

According to Optec’s Jeff Gatzow, recent refinements in midpower LED construction, coupled with end users’ need for low glare and high efficacy, are leading luminaire manufacturers away from arrays of high-powered point source LED and optics. Light guides, on the other hand, are created using many proprietary materials and techniques and will reach upwards of 85% transmittance, meaning flat lenses can now be achieved.

The ELED2 tunable-white fixture controller is the wireless solution for creating human-centric lighting systems. With two separate outputs—one for intensity, one for color temperature control—the ELED2 can deliver a variety of color temperature and dimming control sequences. When paired with a photo sensor with color correlated technology (like the Echoflex TAP-41), the ELED2 can automatically adjust a fixture’s color temperature in open and closed loop applications. The ELED2 also features Dim-to-Warm technology, replicating a natural look with LED fixtures even as they dim.

Human-Centric Lighting

COLOR TUNING

Concentration at the Push of a Button

PRODUCT

Lights on, curiosity, go! At the Herstedlund School in Denmark, “active light” accompanies teachers and students throughout the day. Its users say it promotes concentration, increases efficiency and boosts relaxation, creating moods that complement the desired situation.

So, for all the talk of color tuning, does it exist? It does, but sometimes you have to go far afield, say Denmark, and the Herstedlund Primary School.

There, after the bell rings, fourth-year students take their seats for the first lesson— not so different than schools around the world. However, when teachers in these classrooms flick the switch, a very different experience follows. Light, more like daylight, floods the classroom, creating a more pleasant atmosphere. Thanks to Zumtobel’s Active Lighting system, teachers have a choice of four pre-programmed lighting “moods,” in line with the precepts of human-centric lighting.

36

ARCHITECTURAL PRODUCTS

1907APSSL02.indd 36

In this case, dimmable, and color-tunable  2 luminaires from the manufacturer deliver the desired learning environment. For example, after lunch, comes the inevitable afternoon lull.

Yet now, teachers can use the tunable light to actively increase attention. In this scenario, as it might be in the early morning, stimulating cool-white light, notes the manufacturer, helps bring the classroom to life. But later, when a group exercise rounds off the school day, a scene with slightly subdued warm-white light provides a more relaxing ambience.

The scenarios were the result of research conducted at the University

of Aalborg, which developed specific design criteria for the classroom lighting “moods.”

Zumtobel worked with researchers to turn these concepts into reality. The project also uses the company’s lighting infrastructure and  lighting management system to collect data. The findings, to date, have now been brought together in a recently published study. In a nutshell, the lighting scenarios of the Active Light system, according to Zumtobel, have helped the school support learning, specifically in the form of helping teachers structure lessons while providing environmental versatility for staff and students throughout the day.

On average, teachers, thus far, change the lighting mood three times a day. Seasonal daylight differences and the spatial arrangement of the classrooms, which face in different directions, all have an influence on the lighting conditions, but it’s not a major challenge, according to Lybeck Casper, sales director of Zumtobel Group Denmark.

“The Internet-enabled, and app-based system means that the four preprogrammed scenarios can be easily controlled by the teachers.”

The color settings and light intensity of all the luminaires in the classroom, he notes, are individually adjustable, and teachers can define their own settings.

Integrating Lighting Design with Architectural Wayfinding Editor’s Note: Following is an extract of a book being written by lighting designer David Rodstein, principal of Rodstein Design, Philadelphia, and being edited by our very own Vilma Barr. As an ongoing series, we’ll be tapping into a number of David’s insights on wayfinding in different spaces, but we begin with an overview of airports.

Whether an airport, train station or bus terminal, lighting needs to lead passengers to the right terminals, train tracks, bus stops. So it is imperative that the lighting design process be considered early during the schematic, design and construction phase, so it can be adaptable to changing needs, and future-proofed for the constant stream of transportation-related upgrades and repurposing that occur in these public facilities. The bottom line: integration of lighting and wayfinding design will create a safe, easy way to navigate space.

Lighting is necessary in conjunction with wayfinding science, and using proper signage adheres to the following concepts:

Navigation Using signage, maps and orientation to get to a destination: where users are and where they’re heading.

Orientation Finding internal compass points: passengers need to know location in the built environment and other destinations.

SEQUENCE IS KEY

Wayfinding must be sequential. The design goal is to seamlessly lead users the entire way to the correct departure gate from the entrance or roadway.

Key points for airports:  Illumination should not interfere with the takeoff or landing of the aircraft.  Roadway and pedes-

trian outdoor lighting should be the full “cutoff optic.”  Use high -rating

A good strategy is to locate low-glare luminaires and cutoff wallpacks on terminal walls facing out.

(backlight-uplightglare) to avoid light trespass and disability glare.

Be sure to coordinate with consulting engineers, who normally take the lead on these critical areas. Also be sure to follow  guidelines.  also has special requirements for security areas.

A progression of sculptural fixtures are icons of illumination at the Los Angeles International Airport.

Drop Off Separate concourses exist for taxis, buses, cars, etc. Signage leads to adjacent areas, but at two steps at a time to segregate arrival and departure, and lead cars to the right space. Next in sequence is signage for airline choices and terminal numbers, which are the “beacons” here—objects such as signs, artwork, decorative lights that lead you to the next step in the journey or the beginning and end. Light levels should meet standards shown for the curb sides, as well as roadway standards for car lanes. Vertical surfaces should be illuminated for pedestrian visibility, as the latter are often crossing streets. Keep in mind pedestrians and baggage do not move sequentially or predictably.

Security

Often the second or third step in the procedure of getting to the plane, lighting again is critical. Back illuminated signage above with the airline logo is the “beacon” here. Baggage tags and paperwork, especially passports, need to be easily read, done quickly and lit properly without excessive light that could wash out a computer screen. Waiting lines, however, should have softer illumination. Passengers may be stressed here due to worry of delays, or simply the hassle of waiting in line. Passenger flow here is typically kept in order by a rope line with a single outlet.

Glowing and blinking lights should be used to guide to the next available agent.

STRONG DIRECTIONAL SIGNALS

Passengers exiting gate areas must choose between baggage pickup and ground transportation. Choices are many, be they car rental, taxi, personal pickup, etc.; passengers may also be fatigued and may not be paying careful attention.

Therefore, at night be aware that too high a light level could create dark adaptation issues.

LEAD THE WAY

A bilingual signage system solved several wayfinding challenges, including providing direction along three different paths to the departure concourse for domestic, U.S. and international flights.

A high-stress area for passengers and agents alike, overly bright vertical surface illumination can cause people to have a silhouette look, reducing identification ability. These areas are also under constant camera surveillance.

A lensed troffer-type luminaire can also wash out a camera image.

Strong light and shadow from accent lights will white out a TV monitor; shadows are black and to be avoided. Use  standards as due diligence.

Boarding Concourse Light levels should be optimized for security, and pedestrian activity. Signage denoting individual gates should be brightly lit beacons with extra illumination during boarding times. They can be backlit or accent lit, meaning they are lit from a spot or floodlight mounted on the ceiling. Passengers often orient themselves by looking down the aisle of each terminal to be sure they have made the right choice, such as not going down Aisle B, when C is intended. The sign and area illumination should get progressively brighter as the boarding time becomes nearer.

Options to consider should include dimming and color change at the gates, as it’s much easier to accomplish now with LEDs and individually addressable fixtures.

Getting people to move in specific directions, and guiding them on certain routes is part of what Gottdiener (1997) and Fajen and Warren (2003) call “steering behavior.” Flight desks should have four times the illumination level of the seating areas.

Gate signage light levels should be 10 times the ambient to catch attention for orientation. Windowed waiting areas offer plenty of daylight, so electric light, at least fixtures closest to the window wall, should be on photo sensors. Waiting areas should be devoid of industrial looking fixtures. Architectural aesthetic grade luminaires calm the atmosphere, be they pendant, indirect, recessed or surface direct fixtures.

The wide-open spaces of airport departure lounges, reached after traversing the low-ceiling corridors containing security, passport and immigration, indicate to the passenger that their pre-boarding and final destinations have been reached. The shopping arcades, replete with enticing accent lighting, area lighting—and often designed for the dramatic effect— encourage retail activity so passengers will spend money in the terminal building.

Baggage Pickup

Soft general illumination with even light levels is required, yet the area should be bright enough to read baggage tags. People, baggage carts, and objects moving in different directions need to be readily visible. Signage is normally backlit over each carousel. Flat-screen TV monitors have replaced most static painted signage and flip letter signs, and can serve as a beacon. Direct overhead lighting, whether recessed downlighting, opal troffers or decorative units, should decrease the perception of time in a place that can feel interminable and stressful.

Customs + Immigration Areas This is an area of high stress, and the lines can feel without end. Overall design should make the sense to time as short as possible. Recall, too, the stress of the customs agents. The areas are under constant camera surveillance.  cameras do not see what the human eye does, so a low-contrast cloudy day theme works best here.

CIRCLES OF LIGHT

Defining the baggage claim area is the ceiling design, with strategically placed multiple flush-mounted circles of light in varying dimensions. They create a geometric contrast to the trio of carousels.

Vertical surface illumination, called wallwashing, can cause people to have a silhouette look if too bright, reducing identification ability. A lens troffer-type luminaire will also wash out a camera image. Strong light and shadow from accent lights will white out a TV monitor; shadows are black, and to be avoided.

High light levels should be used is such spaces.

Use  standards as due diligence.

Lighting design and wayfinding science need to be integrated into transportation facility design. Signage will blend into surroundings if fixtures are haphazardly placed in the ceiling with no thought other than raw light levels. Additionally, added spaces do not account for the unintended consequences of co-joining with the original spaces. When ignored, it can create wayfinding issues. Electronic signage and advanced lighting control can help rectify this problem with much fewer hardware changes. Integration of  lighting and wayfinding design will create beautiful, functional and occupant friendly spaces.

Reduced cooling loads also mean smaller mechanical systems, less equipment, associated ductwork and/or piping costs. Hitting on a few of these top strategies, architects and engineers share some best practices for “cooling down.”

ORIENTATION

By specifying high-performance glazing with a low-solar heat gain coefficient, ’s design enables visual transparency and daylight. The predominance of glass supports the desire for transparency and connectivity, allowing light to filter all the way through the building. High-performance glazing and sunshading systems support natural ventilation strategies for occupant comfort and energy efficiency.

DOUBLING DOWN ON EFFICIENCY

Cooling energy use in buildings has doubled since 2000, from 3.6 EJ to 7 EJ, making it the fastest growing end-use in buildings, led by a combination of warmer temperatures and increased activity. Without efficiency gains, space cooling energy use could more than double between now and 2040.

Made in the Shade Perhaps one of the most effective ways to reduce cooling loads is limiting solar gain. Wherever possible, building orientation can make a significant difference, by positioning the majority of glazing on the east and west elevations.

For the design of the University of Washington’s () Nanoengineering and Sciences Building in Seattle, for example, the overall facility program was “flipped” early on in the design, orienting the laboratories to the west side of the building where its high air changes could remove all excess solar gain.

Perhaps the next line of defense is well-designed shading systems. For ,  Architects selected horizontal overhangs on the east and south façade to cut down cooling loads during the critical summer period, thereby enabling natural ventilation to be the primary cooling strategy, according to Chris Chatto, Associate ,   +, principal,  Architects, Portland.

Similarly,  Studio favors deep overhangs along with high-performance glazing, trellised roofs and adjustable screens. A great example is the

studio’s design for Sonoma Academy’s Janet Durgin Guild and Commons in Sonoma, Calif. (See this issue’s Function feature, p. 74) In addition to specifying low-E glazing, with a low solar heat coefficient, deep overhangs were designed around the perimeter and a trellis extends the roof line over the upper level patio. “To further control glare and light, moveable, wood-slated exterior panels can easily and strategically be placed to block sun, and adjustable louvers and automated exterior sun shades on the south are tuned for user comfort,” explains Pauline Souza, ,  Fellow, partner, director of sustainability,  Studio, Seattle.

Another effective way to mitigate solar heat gain is targeting the roof which acts as a large surface, easily absorbing heat and transferring that energy into the building. Cool, reflective roofs are one option, as they absorb less heat than a standard roof, but going a step further, with a living vegetated roof, the system removes heat from the air through evapotranspiration. Then there are the added benefits of stormwater management and enhanced aesthetics.

UNIVERSITY OF WASHINGTON

In particular, Chatto recommends extensive systems in modular tray applications for reduced installation and maintenance costs. However, unlike intensive systems, they generally can’t be accessed, or fully enjoyed by occupants.

But one should think about the ground, not just the roof. For example, high-performance concrete pavers, with high solar reflectance indices, can further mitigate solar heat gain, both on the roof and as part of the landscape design. Along with pavers, vegetated landscaping can be an effective way to help modify the air and ground temperatures. For instance, large trees and trellised external shades, covered in vines, lend shade and natural cooling.

At the same time, Souza shares a word of caution on selecting climate-specific trees and plants, as irrigation costs can easily offset cooling load savings.

For Sonoma,  selected plantings that respect the local ecology, and landscaped the roof with yearround gardens that support pollinators, provide insulation and enhance the effectiveness of the rooftop  arrays.

Called “chilled sails,” the technology utilizes phase-change material (), in the form of gel, that turns to liquid during the warmer daytime temperatures and solidifies at night via natural ventilation from the nighttime air.

Case in point, at the Nanoengineering and Sciences Building (p. 47), use of — essentially encapsulated vegetable wax, engineered to melt when temperatures exceed 74°F—resulted in an absorption of thermal energy without an increase in temperature, explains ’s

Chatto. Embedded in the interior walls and ceilings, the chilled sails also moderate the interior temperature as it cools and hardens, thereby maintaining a more comfortable air temperature as well as radiant surface. In monitoring performance,  found that the  reduced the building’s temperature by 2°F during peak times, on the hottest days of the

year—thus supporting significant savings in the mechanical systems’ design.

In addition to the  project,  designed chilled sails for the Rocky Mountain Institute’s Innovation Center in Basalt, Colo., together with concrete mass and ceiling fans for this net-zero energy facility. (See the May 2016 issue of Net Zero

Buildings magazine, or the full issue archive at www.nzbmagazine.com).

For Stanford’s Central Energy Facilities building, , concrete mass and natural ventilation are supplemented with chilled beams. (See May 2017 NZB.)

At the Sunset Café in Boston, Bala designed exposed chilled beams to integrate into the architecture and provide energy-efficient cooling.

TRADITIONAL COOLING

Active Cooling While passive cooling methods like shading, natural ventilation, green roofs and landscaping will reduce cooling loads, buildings still will usually require some form of mechanical cooling, particularly in warmer climates.

The good news is that advancements in  technology has reduced cooling capacity per installed unit/sq. ft. of space. At the same time, hydronic options— e.g., radiant systems— and displacement ventilation are more energy efficient than . However, they can’t meet the most intense cooling loads, hence the need for load reduction, says Chatto.

50

ARCHITECTURAL PRODUCTS

1907APFEA05.indd 50

Furthermore, non- alternative systems can be more expensive from a pure  cost perspective, “but reduced loads can allow for system downsizing either at the cooling source— in terms of reduced or eliminated chillers—or at the point of distribution at the floor plate—in terms of fewer pieces of equipment—making more compelling economics,” he states.

Similarly, according to Charles B. Kensky, ,  , executive vice president, Bala Consulting Engineers, water-based cooling systems will normally provide the most energy savings potential, as distributing water

throughout a building is more efficient than distributing air.

SYSTEMS CONTROL

The Big Picture One other factor, notes Chatto, is the fact that the importance of human comfort and productivity is increasing, which is driving designers to look at thermal comfort more holistically. This means that  designs need to go beyond simple air temperature and relative humidity, and consider the following other factors that drive comfort: radiant temperatures, air speed, occupant clothing and activity level.

MULTISITE REMOTE CONTROLLER Building managers are seeking better ways to control systems. The LG MultiSITE Controls Suite, featuring the MultiSITE Remote Controller, is a flexible control panel featuring a customizable home screen with intuitive user interface that allows users to tailor functions.

UNCONVENTIONAL COOLING Managing indoor air quality is an impactful step to ensure workforce safety and employee comfort. High-volume, low-speed () fans differ from traditional high-speed floor fans in reduced noise, minimized energy consumption per sq. ft. and significant cost savings— fans require less than $1 per day to operate. They also prove to be safer due to cordless design. In addition to regulating warm climates,  fans also focus on establishing and regulating cool climates. Pictured: The  Fan— fan.

We have some great roofing installations in the section; I particularly love the integrated PV and standing-seem application on the opposite page. With a very rainy spring in the Midwest, I’ve especially got roofing on my mind, including metal options, as I found water damage on the ceiling of son No. 2’s room, as a result of some shingles tearing away with spring storms. And after 25 years of habitation, I also had water damage on the ceiling of my front room to match damage from seals around skylights that had gotten bad over the years. Actually, having taken a course on roofs, I learned that the builder of my

In mentioning metal roof options to my wife, however, I immediately received flak about the noise of falling rain. home did not properly ventilate the attic space, and thus I suffered the results of condensation damage over the years. Now it’s time for a new roof. Beyond standing seam, I’m considering an array of stamped metal options that look like slate; as well as a number of other, great-looking faux cedar-shake options. In mentioning metal roof options to my wife, however, I immediately received flak about the noise of falling rain.

This comes as no surprise to Renee Ramey, executive director of the Metal Roofing Alliance, as she says it’s easy to understand how the myth of noisy metal roofs started. On its own, metal can make a pinging noise when struck. However, for a roof, sound transmission depends not only on the roofing material, but the roof decking, insulation and installation techniques. Quality metal roofs installed over a solid substrate such as plywood, or even an old asphalt roof, with proper insulation and fasteners, she says, will greatly reduce sound transmission. “Today’s metal roofing material is often manufactured with formed or texturized patterns that help break up the impact of drops hitting the roof, leading to reduced sound. The result is a roof that is no louder than other roofing types.”

I’m a believer. Stay tuned next issue when we delve much deeper into roof considerations.

TALLEST PASSIVE HOUSE BUILDING FEATURES UNIQUE COLORED FAÇADE As the tallest passive house building in the world at 26 stories, The House at Cornell Tech, designed by Handel Architects, features an innovative system of prefabricated metal panels. Triple-pane windows, mineral wool insulation and air and vapor barriers were factory-sealed into large, single-story curtainwall assemblies and then hoisted on to the building as fully integrated units. The super-tight insulation, combined with highly efficient heating, cooling and fresh-air circulation systems, reduces energy consumption by 70%, as compared to conventional designs.

Standing at 26 stories, the House at Cornell tech is the tallest passive house in the world. While the façade is impressive, the bigger story is demonstrating the feasibility of large passive house projects in the United States.

To really make the design pop, Handel worked with PPG to custom color the façade with Duranar MXL coatings.

“We were looking for a paint that would be dynamic— one that would add depth and life to the façades,” adds Deborah Moelis, principal, Handel Architects, New York City. Circle 375

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.

A custom glazed veneer system based on Kawneer’s 1600 Wall System1 Curtainwall and 1600 Wall System2 Curtainwall was attached to structural steel tubes to support large expanses of glass.

Glass

PPG (Vitro) Solarban 72 Starphire ultraclear annealed float glass provides high visible light transmittance (), exceptional clarity and superior solar control performance.

Brick

Sioux City Brick “The bricks are proportionally longer and thinner than typical bricks,” explains Clapham. “This was important from a design standpoint, as it allowed us to compose perforated screens in key areas along the façade. At street level, it brings filtered daylight to teaching spaces, and on the upper level, the mechanical air intakes.”

Terracotta

NBK Architectural Terracotta Located in the upper lobby within the glazed structure, Terracotta Bagutte and fin elements read as a gateway to the campus, and lantern by night, says Clapham. “The terracotta shroud around the simulation environments modulates the natural lighting and was composed to evoke an abstract anatomical expression.”

The goal of the University of Kansas Medical Center Health Education Building () design was to encourage connectivity and inter-professional collaboration. CO Architects, in collaboration with Helix Architecture + Design, balanced the use of brick, glass and metal to create a contemporary, iconic presence on the campus that stands out—yet fits in.

The project’s iconic four-story glass “lantern” box features a double skin that puts the project’s progressive programs on display. A 250-ft. “building” bridge passes directly through the center of the  and connects to the adjacent educational building.

The enclosed bridge, full of student life space, functions as an energized, interdisciplinary loop.  serves as the primary teaching facility for the university’s schools of medicine, nursing and health professions. Therefore, its program blends both traditional and new, technology-rich, teaching environments for inter-professional and various types of experiential learning. “It is a simulated hospital environment for training students together—comprised of high-fidelity inpatient and outpatient settings,” says architect Tanner Clapham, , , Senior Associate, CO Architects, Los Angeles. “This gives students a chance to practice patient care in teams, all geared toward improving real world patient experience and health outcomes.”

Inside the Outer Wall The project called for large expanses of glass throughout, which required the support of structural steel. Glazing contractor and installer, JPI Glass, worked with Kawneer to develop a custom-glazed veneer system based on Kawneer’s 1600 Wall System1 curtainwall and 1600 Wall System curtainwall.

The system was attached to structural steel tubes to not only support the size and weight of the glass, but also to fit within the budget.

Approaching the project through the lens of the school’s guiding principles of creativity, inclusive community, exploration and innovation, the WRNS design team embraced a connection

“We enacted a design that led with human comfort and natural beauty, and sought out creative solutions to meet the client’s strict sustainability and energy efficiency objectives,” says Souza.

The architects took an integrated approach every step of the design-build-postoccupancy process, including educating the community, empowering stakeholders and policy makers, and challenging its own industries to target multiple sustainable benchmark systems.

The approach was

carried through construction to ensure the  Red List imperative was met.

“We worked tirelessly with each other to meet targets throughout, communicating with the client, the learners, the internal teams and the larger green community,” says Souza.

The Exterior The envelope acts in concert with weather and times of day, modulating temperature and light to accommodate various program uses. A performative envelope dominates, with operable windows and coiling doors opening to gardens. Sliding wood screens and mechanical sun shades, made from salvaged western red cedar, filter sunlight and reduce demand for mechanical heating and cooling. A weather system, tied to the building management system, helps exterior shades modulate.

For energy efficiency and passive solar gain, highperformance, low-E glazing and naturally heat-regulating compressed earth blocks—and environmental alternative to cement—were used. The earth blocks are made from regional soils and replace cement.

Reclaimed wood from local houses and a tunnel in Oregon, were used extensively for the building enclosure and dining space.

SHADING

The building envelope adjusts to the climate with automatic exterior shades on the south and movable wooden screens (right) to the north and west.

Challenges Met  One challenge with biophilic implementation was integrating the elements and attributes in a technologically based program. These programs do not inherently perform well with daylight and a connection to varied conditions. While integration of color and material and easy access to gardens provide some connection, the rooms were designed to be more controlled due to technological requirements.

 Given the site’s slope, the lower level has a large elevation that holds back the slope. The maker space is divided into an area for making (cutting, welding), and an area for assembling and seminars. The making area requires more control of light, and given the location against the hill, depends on mechanical ventilation and artificial light to support activity.

 All materials were tracked for harmful toxins and sourced locally. Including proper ILFI documentation was tedious, but necessary to meet project sustainability goals.

 During construction, Santa Rosa experienced its wettest recorded year since 1902. The rain-filled construction schedule was met with lean construction techniques, positive attitudes, and a drive that spoke to the significance of the project for the community.

A More Passive Approach

UPPER LEVEL

Taking advantage of the mild climate, natural ventilation and ceiling fans are used throughout the shoulder season, providing user control, passive cooling, and a high degree of user adjustability.

During extreme months, geoexchange and radiant heating and cooling in slabs and panels, drive down energy and water demand—expected to provide 10% to 15% of the annual cooling demand. The mechanical system captures waste heat from the ventilation air and refrigeration system in the commercial kitchen, and uses it for space heating and domestic hot water production.

TRACKING SUSTAINABILITY

Driving toward deep sustainable thinking, the team met with regulatory agencies to explore policy changes on reclaimed water strategies, reduced carbon materials and alternative energy sources. “Even if in environmentally forward California, we worked overtime with the municipality to implement strategies ahead of code, including incorporation of a geoexchange system, blackwater treatment strategies and low-carbon masonry units,” says Souza.

Energy Performance The team rethought the grid and built clean on-site power generation, aligning with microgrid aspirations. The commercial kitchen is powered solely by the PV array atop the building.

ENERGY & POWER SNAPSHOT

Energy Target

The actual performance will be evaluated against the modeled performance data. The building’s  dropped to a projected -4.85 kBTU/sq. ft. thanks in part to the 143.28kW PV rooftop system.

Energy Use Intensity (EUI)

Gross EUI = (721,405 kBTU)/(18,915 sq. ft.) = 38.14 kBTU/sq. ft.

Renewable Production Intensity (RPI)

RPI = (813,167.6 kBTU)/(18,915 sq. ft.) = 42.99 kBTU/sq. ft.

Net EUI (EUI less RPI)

Net EUI = 38.14 – 42.99 = -4.85 kBTU/sq. ft.

The project targeted three benchmarks:  v3 Platinum, Living Building Challenge Material and Energy Petals, and  Building Standard Education Pilot. These targets were used to ensure good indoor environmental quality.

Material selection was guided by  Materials Petal focusing on health and transparency. Materials with low-VOC and in compliance with  Standard Method v1.1-2010 were sourced. The General Contractor tracked materials, including glues and substrates, to make sure they didn’t have any of the 815 harmful chemicals listed on ILFI’s Red List in them.

Exterior Panels/Cladding

Enhancing the Game Day Experience Throughout a multifaceted process, a cohesive team, in close contact with each other, was able to deliver the project goals to Clemson University in a timely fashion.

CHALLENGE

SOLUTION

Clemson University recently targeted a full-scale renovation of its historic Littlejohn Coliseum to accommodate the institution’s growing athletic program. The arena, which was first opened in 1968, underwent a series of additions in the mid-2000s.

The previous facility was not of sufficient size to accommodate the university’s growing needs.

Moreover, the facility’s exterior façade showed serious signs of wear and tear. “The coliseum was constructed with exposed steel columns and exterior wall plates, which over the years had patinated to a dull rust color, leaving heavy stains on the concrete pedestrian apron that surrounded the facility,” says Scott May, Principal at LS3P, the architecture firm responsible for the design.

According to May such collaboration extended to the choice of metal panels for the façade. The LS3Pled design team had used  insulated metal panels [IMP] on several previous commissions. “We evaluated a number of products but returned to  not only for its familiarity and price point, but also because a trusted installer [Steel Clad] familiar with  was brought on by the construction manager to complete the installation.”

Renovations to the coliseum utilized the multi-purpose capabilities of the Formawall Dimension Series IMPs. Addressing aesthetic, performance and technical challenges, these metal panels in Arctic Ice and Slate Grey, improved the building’s overall modern appearance and the fan experience at the arena.

A renovation was the perfect opportunity to provide a cohesive aesthetic to the overall structure, while creating a top-notch arena for competition in the powerhouse  Conference recruitment.

INFLUENCE

The new entrance to Littlejohn, the Burton Gallery, would be a high-volume, 10,000-sq.-ft. hall that needed to provide an eye-catching first impression to fans. “Through a series of design studies, our team collaborated with both the athletic director and the campus planner to develop a design that reflected the character of the campus and the aspirations of the athletics department,” says May.

“The exterior steel cladding plates were originally uninsulated, which transferred a tremendous amount of radiant heat into the facility,” says Mays. “CENTRIA’s insulated metal panels offered an opportunity to not only clad the facility in an insulated skin, but possessed both colors and textures to unify the building façades and impart a contemporary aesthetic.”

Ceiling Systems

Casino Lobby Maintains Design Pechanga Resort & Casino has undergone a major expansion that nearly doubled the size of the existing lobby and registration area. To maintain continuity of design with the existing lobby, the design team chose a custom linear metal ceiling in a wood-look finish.

CHALLENGE

SOLUTION

The growing popularity of the Pechanga Resort & Casino in Temecula, Calif., triggered a major expansion that nearly doubled the size of the existing lobby and registration area.

Working with the You Inspire Solutions Center at Armstrong Ceiling & Wall Solutions, the design team was able to meet these criteria with a custom MetalWorks Linear ceiling system in an Effects Wood Looks Dark Cherry finish.

When designing the new addition, which features a glass atrium that streams daylight into the expanded lobby, the design team from Klai Juba Wald Interiors, of Las Vegas, was charged with incorporating some of the existing feature elements into the new space.

“We needed to have continuity with the existing design, yet with new character design elements, fresh and updated,” says Ann Fleming, principal at Klai Juba Wald Interiors.

INFLUENCE

The Pechanga Band of Luiseno Indians, which owns and operates the casino resort, liked the idea of continuing the look of the existing wood ceiling into the new space. “The client prefers warm finishes with handsome woods,” explains Fleming. “Their idea of continuing a wood ceiling in the lobby expansion felt appropriate.”

However, unlike the existing wood ceiling, the new ceiling would need to be accessible to allow maintenance of the mechanical components in the plenum.

“We had to facilitate the building systems into the space, including the lighting, so the durability, accessibility and maintenance of the ceiling was critical,” she adds. The new ceiling would also need to provide visual interest and allow light from the atrium to play off the design.

The 7,625-sq.-ft. ceiling, which is suspended 30 ft. above the floor, includes more than 100 triangularshaped pods made up of about 20 panels each. The pods consist of two different custom-shaped triangles: 10 ft. 4 in. × 15 in. and 14 ft. 5 in. × 9 ft. 7 in. The pods are installed at various slopes and are separated by a 9-in. gap, creating a fractured, geometric visual. “By creating that fractured look with different shapes at different heights, we were able to break the expansive ceiling, allow some light play, and make it more organic in feel than a straight, flat ceiling,” explains Fleming.

Armstrong Ceilings supplied more than 300 custom perimeter trim types at the exact length and mitered angles required for each corner, along with elevation points for each pod, enabling the ceiling installer to build and suspend the pods correctly.

Blending Historic with Modern Studio unites historic architecture and modern design for collaborative office space.

CHALLENGE

Eastlake Studio was faced with adversity when plans to convert the building that had been their long-time residence to a hotel and condos became a reality. The studio had been residing in Chicago’s Tribune Tower, for approximately three decades. The change of vocation of the tower from commercial to mixed-use residential provided the architecture firm an opportunity to address the challenges of the former office while opting to move to another historic building.

INFLUENCE

The limitations of the original office were motivators for designing the new space. According to Kevin Kamien, principal at Eastlake Studio, the main goal of the project was to maintain the open working relationship and studio vibe, emblematic of the organization. The new office still encompasses the most beloved features of the old space—cityscape views and areas for creative production—while also delivering elements it had been missing.

“We wanted to take the working relationships on our floors and transcribe that into a new space with natural light, keeping the views, but also giving us all the things that we were missing: meeting space, more collaboration rooms, and formal meeting areas,” stated Kamien.

Eastlake Studio’s single-floor office is divided into two suites, one occupying the north side of the space, the other one the south side. The north side suite, a section once part of the original art deco building, offers views of some of Chicago’s most notable architecture, a large formal conference room and two executive suites providing a respite from the active, south side suite. The south side suite encompasses employee workstations, private phone rooms, collaboration areas and a resource library where the design team can deliver presentations.

open and airy design of the work-station area was preserved, a continuous run of Nera linear luminaires from Focal Point were selected based on the fixture’s modern, unobtrusive design, center void and Power Up technology, which eliminates the clutter of power cords by delivering low-voltage power through suspension cables. Other areas were illuminated by the company’s Seem 4 suspended luminaires in a custom black finish; they seamlessly blends with the dark open ceiling structure. Seem 2 Asymmetric recessed luminaires were used to illuminate the hallway leading into the large open work area.

Thanks to the various distribution, configuration and lumen output options in the Nera collection, Eastlake was also able to use individual units of Nera linear luminaires in the north side suite, offsetting the confined feeling that the lower ceilings deliver while bringing a cohesive look to the office.

SOLUTION

Connecting these two areas is a long corridor with a multi-use seating area, where a feature wall prominently displays the company’s revamped logo.

Lighting proved a binding element. To ensure the

But thanks to an ambitious renovation, featuring more than 1,000 historic replication windows from Graham and resulting in LEED Gold recognition, it’s now a state-of-the-art learning environment for the 21st century. The building’s inclusion on the National Register of Historic Places and the need for Historic Preservation Review Board and Commission of Fine Arts approvals made the window portion particularly challenging.

t is often said that college is the “best time of a young person’s life.” For that reason, it is easy to forget that institutions of higher learning are, in fact, businesses.

And, in 2019, many industry experts are finding that being in the business of higher education is rough. In the article “9 Higher Ed Trends to Watch in 2019,” published by EducationDive, author Ben Unglesbee writes, “Pressures on colleges, as 2019 opens, are numerous.

They include—but are no means limited to—historically low financing, competition over shrinking pools of potential students, slowed growth in international student enrollment, and a push from nearly all stakeholders for proof of return on their investment, often in the form of workforce-ready graduates.”

Another challenge is understanding and accommodating the needs of the latest generation of students that do enroll. Generation Z, also called the iGeneration, refers to people born between the mid-’90s to the mid-2000s. By that definition, in 2019 this group

ranges in age from 14 to 24. They are considered the most digitally native and digitally addicted generation that has ever stood on a college campus. In fact, a 2016 survey, conducted by HuffPost, noted 40% of Gen Z self-identified as digital device addicts. In practical application, these digital and social-media savvy students are often found to lack, or have underdeveloped, person-to-person social skills, which can dramatically impact their experience during the first year of college.

BUILD COMMUNITY IN RESIDENCE HALLS

As colleges and universities look to attract and retain Generation Z students, engineering a better social experience has become an important piece of the equation. As a result, the demand for communal, community-building, see-and-be-seen space has skyrocketed. This has motivated designers to reconsider a number of different areas around campus. Residence halls are being designed in community-centric models. Bathrooms are moving from down-the-hall to the hallway. Outdoor spaces are being repurposed to invite and entertain students, faculty and staff. In short, administrators have never been more invested in helping students to develop both academically and socially. Designers are uniquely equipped to help them realize their goals by revamping the traditional (and in some cases emerging) design approaches to many of these interior and exterior spaces.

The demand to get students out of their rooms and ensconced in student community, especially their freshman year, has inspired architects to overhaul the traditional layouts of the residence hall increasing the

ways that the space fosters collaboration, communication, and coincidental run-ins. One of the guiding schools of thought on the topic touts the importance of deconstructing large residence halls into smaller, more manageable, and personalized communities or “pods.”

The target maximum for each pod is 40-50 students per resident assistant. This is considered the optimal size for an RA to effectively build relationships with each student and improve the interpersonal experience of each resident over the course of the year.

Along with these smaller subdivisions of the student body, there is a growing demand for a greater variety of programmable space, such as community study space, lounge space, team project rooms equipped with smart boards and kitchenettes. “Residence halls are now considered 24/7 types of buildings,” explains Jeff Juliano, Principal at Collins Cooper Carusi Architects.

“The residence hall must be equipped to meet the evolving needs of the students and their workload. For examples, many schools are increasing the number of team-oriented projects. Designing the residence hall to accommodate group sessions enables students to work outside of the library and offers them more flexibility on when and where they schedule their meetings.”

The floorplan of The New Commons residence hall at Life University placed private shower and toilet enclosures in the hall, adjacent to the communal vanity bar.

years, restrooms in residence halls were some version of the shower-down-the-hall layout, including banks of hardly-private toilet compartments, shower stalls and rows of vanity sinks. Then, in the last 10-to-15 years, colleges started offering bathrooms, en suite, as a way to make their facilities more attractive to students who wanted more privacy than the down-the-hall bathroom provided.

Unfortunately, the en suite design was expensive and inefficient. There were two types of designs commonly seen. In one, the bathroom was shared between two double-occupancy rooms, offering a 4:1 facilities-to-student ratio, which was certainly adequate.

Another design created a double-occupancy room with a private bathroom, delivering a 2:1 ratio, which was much more expensive in context of the number of products and materials, plumbing and square footage it required.

Recently, a new approach to restroom design has emerged that provides an optimal 3:1 facilities-to-student ratio with enclosed shower and restroom facilities that are highly private. It also enables more of that communal, programmable space to be incorporated on each floor, without requiring more square footage.

The crux of the design, the reason that it’s so different, is that the restrooms, showers, sinks, hand dryers, etc., are pulled out of the rooms and moved from the down-the-hall oasis to the middle of the corridor. The showers and toilets are contained in fully enclosed compartments that are absolutely private. Shared community vanity bars are located in the halls, adjacent to the private shower and toilet rooms.

The design is revolutionary, delivering a floorplan that successfully satisfies goals that often seem at odds with one another, creating a better experience for students while making better use of the square-footage allotted to the student residences. Let’s take a look at a student residence hall project that illustrates how this incredible new approach to restrooms translates in the physical brick-and-mortar world.

LIFE UNIVERSITY’S NEW COMMONS

Designed by Collins Cooper Carusi Architects in Atlanta, The New Commons at Life University is a 362-bed residence hall specifically designed to engage, comfort and inspire the students who reside there.

Organized into 12 distinct living/learning communi-

ties, the pod-centered design illustrates how residence halls can successfully create community-based living with many communal, programmable spaces, and offer the private restroom experience students prefer.

Each community is designed to evoke a different emotion and is inspired by Life University’s vision “to give, to do, to love and to serve,” which is reflected in the famous faces featured prominently in the different living communities—Nelson Mandela, Maya Angelou, Helen Keller, Mother Teresa, Dr. Martin Luther King Jr. and others. “The types of community space found in each pod is slightly different to encourage students to roam through the residence hall and check out all of the amenities available to them,” explains Juliano.

“Some spaces feature smart board technology, others have writable glass surfaces. The lounges are different from one space to another as well.”

The restrooms are a particularly impressive aspect of the design. “In order to prioritize the creation of these spaces, we needed to make the most efficient use of the interior space possible. To that end, we were able to create two narrower corridors, and incorporate the showers and restrooms and sinks in between.

This approach enabled us to heighten privacy, as the toilet and shower compartments are individual and enclosed. Bringing restrooms deeper into the interior allowed us to give more windows to the resident and communal rooms. And we encouraged community gathering with the communal vanity bar.”

One of the most surprising aspects of the design, notes Juliano, is that it delivers all of the desired functional spaces and a top-of-the-line experience without increasing the necessary square footage.

Placing the restroom in the corridor requires some unique considerations when selecting the right accessories to carry out the vision. Here are a few tips: • Consider the size of the community or “pod” you are designing. Communities larger than 60 can begin to spread spaces too far.

• Locate the community spaces linked with a particular community in close proximity to the bathrooms.

• Consider the potential for noise and the location of room doors since the vanity bar is open to the corridor.

revealed that noise at night can negatively impact people trying to sleep. Noted effects include elevated levels of stress and poor sleep quality.

In an attempt to protect students from unwanted noise in the space that never sleeps, designers can specify products that produce less overall noise. Hand dryers, for example, can be specified with a variable air flow, which allows them to operate at a lower decibel level. Facilities personnel can adjust the output air speed from 224 mph, which produces a sound level of 67.2 dB-A at 2m down to 145 mph, and a sound level of just 62.9 dB-A at 2m. For context, a typical vacuum cleaner produces about 70 dB, whereas background music or normal conversations are often measured at around 60 dB. Although the difference between 67.2 and 62.9 dB may not quantitatively appear significant, sound measurement is not linear. A noise rating of 60 dB is considered half as loud as a noise rating of 70 dB. These quieter hand dryers also feature an antimicrobial cover impregnated with silver ions and a 3-layer filter, in which the HEPA layer captures airborne particles up to 0.3 microns, the anti-microbial layer eliminates 99.9% of bacteria, and the layer of activated charcoal fights odors, improving the overall hygiene of the drying station.

DESIGN TIP

SELECT LOW-MAINTENANCE PRODUCTS

“Maintenance and serviceability drive a lot of our decisions in terms of washroom accessories in the student residence hall,” explains Juliano. “We need these spaces to be easy to clean, and even easier to maintain.

We prefer hand dryers over paper towel dispensers, because students don’t always put disposable items into the garbage can, and hand dryers consume less paper products.”

One product that can help achieve the low-maintenance objectives of the college and university restroom space is the multi-feed soap dispenser. This solution features a high-capacity central reservoir which holds up to five liters of liquid or foam soap that is automatically supplied to up to six separate soap dispensers.

This multi-feed structure better equips soap dispensers to meet the need of the space, enabling more popular stations access to more soap, instead of seeing them fail before the less popular hand washing locations.

This multi-feed soap dispenser system also streamlines the maintenance process by allowing maintenance personnel to pour soap into one larger top-fill reservoir, instead of refilling several smaller dispensers that are often accessed below the sink.

Washroom accessories have also been designed to

HEIGHTEN PRIVACY IN TRADITIONAL RESTROOMS

Not all of the restrooms in The New Commons residence hall have been moved to the hallway. The first floor of the residence hall features a 200-seat dining café/commons area that services the entire Life community. Restrooms on this floor follow a more traditional public restroom layout that includes a bank of toilet compartments and the traditional multiuser vanity.

Students today have a more heightened sense of privacy—as so much of their lives is so regularly exposed on social media. High-privacy restrooms offer a zero sightline design that has eliminated the gaps often found on either side of the door. The zero sightline feature is important, because gaping sightlines can make people on either side of the closed door uncomfortable. People inside the compartment feel exposed. People at the sink or hand dryer can tell the stall is occupied and actively try to avoid catching a glimpse. In an area trying to build community, these encounters can be especially awkward as they occur amongst people who may have class together or will see each other again, perhaps daily.

Sightlines can be a result of several different factors. There could have been an ordering error, installation error, a mismeasurement, or perhaps something at the site was not as expected, but, ultimately, if a sightline exists in the toilet compartment, it’s because the compartment system specified in the restroom was not designed to prevent a sightline from occurring. Luckily, that is changing and today designers can specify high-privacy compartments that have been engineered with features that prevent sightlines in the installed system.

High-privacy compartments can be selected in a variety of materials and the different materials have different privacy-enhancing features that prevent sightlines. Partitions made of phenolic and solid plastic materials can feature door panels that are routed on both sides, the side that locks and the side that hinges.

The adjacent pilasters have reverse routing, so that the edges of the door panel will overlap with the edges of the pilasters, eliminating sightlines. When the door is closed, the door panel and pilasters will lie in the same plane, adding elegance to the solution. Stainless-steel and powder-coated steel partitions often eliminate sightlines by using a continuous strike keeper on the locking side of the door panel and a hinge-side filler on the hinged side of the door to obstruct any view into or out of the compartment.

Specifying taller compartments with smaller clearances under the door and partitions also adds privacy by making it more difficult to see under or over the dividers and into the high-privacy stall.

CREATE INVITING OUTDOOR SPACES

(Top) High-privacy toilet compartments prevent sightlines and make it more difficult to see under or over the stall. (Bottom) Toilet compartments made of phenolic and solid plastic materials feature routed door panels that overlap with the adjacent pilaster, preventing sightlines.

Another goal working its way onto more and more college and university master plans is an increase in outdoor gathering spaces located around campus. Officials hope these outdoor venues will make the campus more ‘sticky’—a place where students, faculty, and staff want to linger. The resulting outdoor additions have ranged in cost and complexity from simple outdoor seating to carefully designed courtyards, park centers, and even a fire pit.

However, creating successful outdoor gathering spaces oftentimes requires more effort than putting chairs out. An important aspect of enticing people to linger in an outdoor space is adequately controlling the daylight and heat exposures that can be intense on bright, sunny days. This challenges architects to create inviting and beautiful outdoor areas that enable people to connect with nature and each other, while simultaneously protecting them from some of the outdoor elements.

Tensile structures are becoming a go-to solution for these types of projects as they can manage light and heat exposure, without requiring a massive structural presence that would further distract from the natural surroundings. These minimalist elements are constructed from a lightweight, flexible fabric membrane that is held in place with steel cables. These structures can be erected in a wide variety of original shapes, offering designers a tool to expand and enhance their creative vision.

Tensioned structures can offer an effective solution for providing shading structures and roofs for open air constructions. They protect people in the

space against bad weather, the heat of the sun, and other environmental elements. The high-performance composite fabrics are extremely durable in harsh conditions. The fabric features a special topcoat that keeps the fabric cleaner and makes it more resistant to photo-oxidation and micro-cracks, which enables the fabric to last longer.

Modular behind-the-mirror systems contain a large-capacity soap dispenser and the option of a paper towel dispenser or a high-speed hand dryer.

OUTDOOR OASIS AT PENN STATE

It was time to change out the old water tower on the north side of the Penn State University campus. The old tower supplied water to many of the dorms and buildings on the State College campus and it needed to be replaced to meet regulations for water quality and quantity.

Situated in the middle of the Arts & Architecture College district, Penn State decided to allow students from the Stuckeman School of Architecture and Landscape Architecture to provide feedback on and propose alternative approaches to the university’s plans for the project. This resulted in a highly-collaborative design effort, led by Derek Kalp, PLA, ASLA, the landscape architect at the Penn State Office of Physical Plant, and the students of the Stuckeman School, of which Kalp is an alumnus.

Ultimately, the old water tower was replaced with a regulation-friendly version, and the dated outdoor landmark was transformed into a fun study and hang-out spot for students. The new water tower space includes seating, lighting, a stage area, and a tensile shading structure that effectively manages environmental elements to keep students comfortable.

Aesthetically, certain elements in the water tower were selected to better balance the overall scale and feel of the project, and to complement the expansive natural space surrounding it.

“Because the tower itself is so large, we wanted to create a canopy to stop the eye,” said Kalp. “The legs of the water tower were painted brown to emulate nearby tree trunks, while the tower itself was painted a light blue to match the sky.”

He adds the unique shape of the canopies is reminiscent of a spider plant, as the climbing baffles on the legs, and web-like canopies overhead, work in concert to distinguish the canopy from the rest of the tower.

At night, the space beneath the water tower remains a place-to-be-and-be-seen with a veritable light show

that washes the seating section in vibrant purple, pink, and blue illumination.

In addition to the distinctive aesthetic that the canopies contribute to the project, the tensile structures serve as a shelter to protect students from the tower’s condensation and provide shade, keeping visitors cooler and more comfortable during the heat of the day. “Water from the tower is around 52°F and condensation will inevitably form and trickle down the tower,” explains Kalp. “The canopies allow the space under the tower to be usable almost year-round as the fabric is durable enough to withstand not only the dripping condensation, but also rain and snow.” The fabric also manages available daylight and heat, allowing two times more natural light transmission than standard weldable PVDF membranes and twice the heat protection, safeguarding the comfort of students using the outdoor space for studying, performing, or relaxation.

According to the Penn State Daily Collegian, “Even on some of the gloomiest days in Happy Valley, students still like to take advantage of this space.”

DESIGN TIP

MANAGE SUNLIGHT WITH TENSILE STRUCTURES

In terms of finding a composite fabric that will perform as needed, there are common performance metrics that describe how the fabric manages daylight and heat. Three important metrics are visible light transmittance, U-value—also referred to as the heat transfer coefficient or thermal transmittance—and the solar reflectance index.

Visible light transmittance measures the percentage of visible light energy in the solar radiation that is transmitted through the fabric. Higher visible light transmittance values indicate that greater amounts of visible light are allowed to pass through the fabric and into the interior. Lower values indicate that the fabric effectively blocks more of the present daylight from entering a space.

Fabrics are also given a U-value, which is a measure of the heat gain or loss that occurs through the fabric. The lower the U-value, the more slowly heat is able to transmit through the material, indicating that the fabric is a better insulator. U-values are measured in watts per square meter per Kelvin (W/m2K).

Abu Dhabi boasts a desert climate with temperatures regularly climbing over 100°F, nearing 110°F, especially June through September. Architects Pascall+Watson UK & Aecom Abu Dhabi were challenged with designing Promenade spaces that could keep students, faculty, and staff comfortable as they walked around the campus during the heat of the day, while achieving an impressive rating from the first Arab green building program.

The Estidama Pearl Rating System (PRS) is a green building rating system that was designed to address the unique needs of this region’s distinctive hot and arid climate. Built upon four pillars—Environmental, Economic, Cultural, and Social—the program provides a framework for the sustainable design, construction and operation of environmentally-conscious and socially-responsible communities, buildings, and villas. Projects can earn ratings of 1-5 Pearls, based on their ability to satisfy the various mandatory and optional credits. A 5 Pearl rating is the highest possible designation that can be received.

As of May 2010, all new buildings and communities built in Abu Dhabi must comply with Estidama—a word that means sustainability in Arabic—and fulfill the 1 Pearl requirements, at a minimum. All government-funded projects are required to achieve a minimum 2 Pearl rating. This pro-active green building strategy demonstrates Abu Dhabi’s commitment to

establishing itself as the sustainable Arab capital and placing the United Arab Emirates (UAE) at the forefront of urban sustainability.

The design of the Promenades at Zayed University achieved a 5 Pearl rating. Ultimately, designers created a double-skin tensile roof that layered a beautiful composite fabric with a highly translucent fabric that would improve the overall luminosity achieved on the interior. The tensile roof served as a daylight management tool that could effectively control light and heat exposure with a sophisticated fabric system that allowed visible daylight to penetrate the interior space, reducing the amount of energy necessary to light the interior during the day, while successfully impeding much of the heat.

The daylight management performance of the double-skin tensile roof is impressive. The visible light transmittance is 3.1%, which represents an infusion of approximately 3,000 lux into the interior on a bright sunny day. The roof achieved a Solar Reflectance Index (SRI) value of 81%, which limits the heat island effect, and the U-value is 2.9W/m2/°K. DESIGN TIP

SELECT DURABLE HARDSCAPES

Hardscaped areas can help to foster the opportunities for social engagement and collaboration so desperately needed throughout a campus today. Beyond the street-front space that is typically paved, beautiful plazas add a welcoming flair and after-class gathering space to building exteriors. Courtyards complete with landscape and hardscape elements, outdoor furnish-

Solar reflectance index (SRI), as defined by the USGBC, is “a measure of the constructed surface’s ability to stay cool in the sun by reflecting solar radiation and emitting thermal radiation. It is defined such that a standard black surface (initial solar reflectance 0.05, initial thermal emittance 0.90) has an initial SRI of zero, and a standard white surface (initial solar reflectance 0.80, initial thermal emittance 0.90) has an initial SRI of 100. SRI is calculated according to ASTME 1980.” The SRI can be used as an indicator of how hot a surface is likely to become when solar radiation is incident upon it. The lower the SRI, the hotter the material is likely to become when the sun is shining upon it.

process equips the concrete paving stones with incredible anti-wearing features that prevent the surface from appearing faded over time. The finer, more concentrated top layer blocks the larger, lighter color aggregates from ever showing through.

Designers, now, can choose concrete paving solutions that will stay looking like new longer. These surfaces offer an extensive selection of colors, textures, and sizes, such as brush texturizing, which offers a richer look and feel, or solutions that feature granite or quartz chips that can make the pavers glisten in the sun. Designers can use concrete pavers to create durable and distinct outdoor areas that support the community-building goals of the institution and reinforce the unique brand identity of the college or university. These hardscaped gathering areas can feature statement-making entrances, serve as a destination for social celebrations, offer beautiful programmable spaces, support pedestrian wayfinding, or be used for parking and look like new for a long time.

Ornate and beautiful hardscapes invite students to walk through the campus, instead of driving around it.

ings, and sculptures are becoming more common as designers and universities look for ways to offer students, faculty, and staff desirable locations to relax and reflect. Ornate walkways encourage foot traffic, inviting visitors and students to walk through the campus, instead of driving around it, and can even serve as a communal site in itself, where student organizations are promoted or campus-wide festivals take place.

Brick, stone or concrete pavers are often the solution used to transform grass or landscaped areas into these thriving and vibrant hardscaped spaces.

While the aesthetic appeal and inherent durability of brick and stone materials have remained relatively unchanged over the years, advancements in concrete pavers have dramatically improved the durability of the paving solution and increased the number of style and finish options now available.

Traditional concrete paving stones became popular because they offered a hardscape option that combined the strength of concrete with a look that was better than basic concrete. Unfortunately, over time and under the duress of foot traffic, exposure to the elements, etc., the smooth surface would wear away, revealing the whitish or grayish color of the aggregate underneath. This made the paving stone appear discolored or faded. The gradual effect of the appearance of the aggregate in concrete paving stones is referred to as etching.

New technologies in concrete pavers do not allow etching to occur. These new concrete pavers use a larger aggregate for the base of the stone, which provides a stronger concrete formulation. Then a high-strength, color-concentrated concrete mixture comprised of finer aggregates is pressed into the top 10%-12% of the stone under several tons of vibrating pressure.

USE PERMEABLE SOLUTIONS

Since a significant contributing factor to flooding is construction related, designers are uniquely positioned to be able to do something about it. Selecting a more environmentally friendly material for these hardscaped spaces can allow the paved surface to capture groundwater—and prevent runoff—as if the natural surface was still in place. This best-of-both-worlds solution is called permeable pavement.

A permeable pavement system is comprised of a configuration of paving stones that feature a void space between individual pavers. This surface of paving stones and void spaces sits on top of a bed of open-graded aggregate base material that serves as

ENHANCE SUSTAINABILITY OF CAMPUS

While increasing the hardscapes around a campus can benefit the sense of community, replacing grassy knolls and the natural landscape can have a negative impact on the immediate environment, in terms of the way that the space manages stormwater and contributes to groundwater reserves.

To clearly understand the issue, a quick lesson on the water cycle is required. When rain falls to the ground, the water either soaks back into the ground, where it percolates down through the soil to the aquifers beneath the surface, becoming groundwater, or it flows over the ground, a result referred to as surface runoff, were it eventually finds land to soak into or is redirected to lakes, wetlands and rivers. The diversion of groundwater to surface water sources is problematic, because of the ways in which the nation uses its groundwater. According to the U.S. Geological Survey, groundwater is one of America’s most important natural resources, as it is used to both supply drinking water in urban and rural locations and supports

irrigation operations critical to agriculture. A reduction in the nation’s groundwater reserves could, ultimately, impede its ability to adequately meet these critical demands.

Impervious hard surfaces, such as concrete and bituminous asphalt, generate five times more runoff than unpaved surfaces, which means they absorb a fraction of the water captured by a natural landscape, rerouting most of the rainfall to surface sources. Commonly used in the construction of streets, highways, and parking lots, the growing coverage of the Earth’s surface in impervious material, and the large amounts of runoff that those hard surfaces produce, is creating flooding issues from coast to coast, as urban areas and increasingly developed suburban areas find themselves ill-equipped to manage the runoff that results from intense or prolonged downpours.

Flooding in large cities and their surrounding metropolitan areas is becoming a more regular occurrence and, according to experts, impervious hardscapes are playing a role in this new reality. Consider the devastating flooding that occurred in Houston in 2017 after Hurricane Harvey made landfall. When experts evaluated the cause of the waterlog, they identified several contributing factors: flat terrain, clay soil, and rampant urban growth, which had covered much of the surrounding landscape with impervious hardscapes.

Permeable pavement is a solution that allows groundwater to be replenished, as if it were a landscape surface.

a holding area for the stormwater as it waits its turn to be absorbed by the subsoil below and becomes groundwater.

In practical application, the way that stormwater is managed by an impervious pavement, and a permeable one, could not be more different. Instead of striking the pavement and running over it—as water does on an impermeable surface—rainwater that strikes a permeable pavement is captured, collecting in the voids between the paving stones and these permeable solutions can manage an incredible amount of water.

Designed to combat flooding, a permeable paver surface is capable of handling more than 100-in. of water per hour, which far exceeds the vast majority of actual rainfall events that occur. The sheer volume of water that these systems can manage enable them to minimize surface runoff. In fact, the runoff coefficient (C value) for permeable paving—which measures the percentage of water that runs off of a surface—can be as low as zero for permeable surfaces when installed at up to a 5% slope. By comparison, bituminous asphalt has a C value of 0.85, which means that 85% of the water that falls onto it will run off. (Source: Design and Construction of Sanitary and Storm Sewers, American Society of Civil Engineers, N.Y., p. 332, 1969).

After rainwater collects in the voids between the paving stones of a permeable system, it filters down into the crushed, angular, open-graded aggregate base material underneath. Stormwater can reside in this detention space until it seeps into the subsoil below or, if the soil infiltration rate is deemed too slow, the stormwater can be directed into the municipal system, water reuse system or other drainageway by an underdrain system.

It should be noted that many stormwater regulatory agencies have strict release rate requirements that determine the volume of water that can be discharged into a municipal system or waterway.

Permeable paving solutions are designed to slow and retain stormwater captured in the system and provide a gradual release rate that satisfies such restrictions. It is recommended that local jurisdictions be contacted directly to establish the release rates that must be achieved for a specific project.

Beyond eliminating surface runoff and replenishing groundwater, permeable paver systems help to clean the water that passes through them, removing harmful pollutants, such as oil. It is so adept at cleaning the water, in fact, that permeable paving is recognized by the EPA as a best management practice (BMP) for non-point source pollutants.

Despite the overwhelming environmental benefits, many designers overlook permeable pavements when selecting the hardscapes for their projects due to a misconception that permeable paver solutions are unattractive or have limited aesthetic options.

According to Elaine Willis, Director of Commercial Strategy, Unilock Group of Companies, that couldn’t be further from the truth. “Designers can choose from a number of different shapes and sizes and an incred-

LOYOLA UNIVERSITY

When Loyola University in Chicago expanded its Lake Shore campus to the south, designers wanted to allow pedestrians and bicyclists safe passage between the southern areas of the school, including the new Institute of Environmental Sustainability building, and several student dormitories, as well as the main campus.

To realize this vision of safe passage, planners decided to buy an entire avenue from the city, close it to vehicle traffic, and replace the street with a wide shared-use plaza, creating one of the first pedestrian-only streets on the city’s far north side.

Beyond providing a safe space for foot traffic, the university demanded that the design of the new plaza reflect their commitment to sustainability. Stormwater management was a particularly important aspect of campus design due to its proximity to Lake Michigan— the majority of the campus is within a half mile of the shoreline, with soils that are highly suitable for infiltration. As such, the impervious asphalt surface that had been used for the city avenue street was replaced with a sophisticated stormwater management system consisting of permeable pavers, native plantings, and a living-learning laboratory for students and visitors.

“In the past, runoff pouring from Loyola’s impervious streets and parking lots created flooding problems

and sent more than 6 million gallons of water annually into Chicago’s storm sewer system and Lake Michigan,” wrote planner Doug Kozma, RLA, Principal at SmithGroupJJR’s Campus Planning Practice.

As part of this initiative, Loyola University has been recognized as a leader in water conservation, diverting 18 million gallons of rainwater from the Chicago sewers.

DESIGN MAKES A DIFFERENCE

As designers address the changing objectives of the college campus, these spaces now foster a social education and encourage collaboration outside of the classroom in residence halls, dining halls, courtyards, plazas and, even, at the fire pit. It’s just another example of how design can make a difference in the way a person lives their life. Consider a student in a dorm room today that is complete with a television, mini-fridge, computer, smartphone, Xbox and bed.

Given their druthers, they may never leave their room, except to go to class, so how can you force them to intermingle with others? Put the bathroom in the hall.

last detail: architectural leader

Community vs v . Connectivity

Joshua Zinder, heads JZA+D’s practice in Princeton, N.J. He’s also vice president of the Garden State chapter of AIA.

In a digital age, brick and mortar needs to have place in the hearts of America’s young.

Upon sojourning beyond the Strip for shelter on my visit to Las Vegas for the  conference, upon putting down a book on Richard the Lionheart, I came away with a clearer understanding of what crusaders must have felt like when they first encountered the hot, arid terrain of the Holy Land—what have I gotten myself into? My colleagues and I, you see, stayed at an Airbnb southwest of the airport, and once you’re off the Strip proper, “authentic” Vegas is really just barren waste. This, of course, begs the question, is this a sustainable way to live?

Someone else asking questions about sustainable living is Joshua Zinder, managing partner of + in Princeton, N.J. With The Venetian as a frequent client, he’s in Vegas much more than I, but as the vice president of the Garden State’s  chapter, he’s thinking of the impact of architecture on young people, beyond simply being an appealing oasis in the desert. In his new role with -, one of Zinder’s missions is to push emerging professionals toward licensure—something, frankly, he says, that’s not been happening with great frequency, but something that’s important for the profession. Why? Part of the answer lies in what Zinder calls a general devaluation of the architect in the eyes of developers, even homeowners, to something that’s simply a commodity vs. a valued, professional service. Lack of licensure among young architects only exacerbates this perception.

CROSS COUNTRY ADVENTURER

TRADITION WITH A TWIST

For Chabad of Hunterdon County, officially the Yakov and Hava Telyas Jewish Center, Zinder is designing a synagogue that is purposefully very modern. “It’s a learning center and a community center first—then a worship facility,” says the architect.

Restaurant Charlie, Las Vegas

Zinder began his long-distance relationship with Las Vegas back in 2006, when a past client, notable Chicago chef, the late Charlie Trotter, asked the architect to design a restaurant for him in the Venetian’s Palazzo tower. Some 30 to 40 projects later, the rest is history.

Acknowledging there’s a bit of an age/values disconnect between his generation and today’s young designers—and their generation as a whole—the architect sees this especially in the firm’s religious work. For example, Zinder is involved in trying to create a more appealing facility for a local faith community. It’s a fascinating problem, as Zinder says it seems young people aren’t necessarily interested in ritual, especially as delivered in traditional brick-andmortar places of worship. Rather, in conversations he’s had on the subject, many young people maintain “connectivity” with their respective communities via Skype or similar social media. “In most cases, they’re joining worship groups more for cultural, than religious reasons.” Zinder, however, is not buying it. For Chabad of Hunterdon County, an orthodox faith community, he is designing a synagogue that is purposefully modern. “It’s a learning center and a community center first—then a worship facility.”

On the subject of societal change, Zinder is equally passionate about increasing density in the urban environment and creating more affordable housing. “And we’re not just talking about the poor— many teachers can’t afford to live where they teach.”

As result, JZA+D is experimenting with the concept of “micro-apartments,” which they’re including as part of a redevelopment of an old Masonic lodge into a 10-unit multifamily residence. They’re also seeing the return of lots of mixed-used properties, with apartments over shops and restaurants.

And this isn’t even addressing immigration. Zinder recalls it was not so unusual, in times past in urban centers, for six people to be living in one room. “And we’re seeing this again lately because of skyrocketing housing costs. Micro-apartments make a lot of sense, because the size makes them affordable enough to allow one to live near where they work.”

Exciting and challenging times. Who says there’s no value to architecture?

FOND MEMORIES

The life of restaurants is often short. The sincedeparted Bourbon Room at The Venetian was a play off the Broadway hit Rock of Ages. Zinder designed it with an 1980s arena-rock theme, and even included guitar-pick shaped tables.
