Annual Green Supplement
by Anastasia Barnes According to an article published on greenbiz.com, the world population will be at nine billion people by 2050, with 70% of those people living in urban areas. The article also suggest that “sustainable transformation is possible with two things; the leadership of city governments and the innovation and delivery capacity of the private sector.” 70% is a lot for any city to handle. So, how do we prepare now? That’s what this year’s GREEN supplement is all about, new technology and methods to sustain our ever evolving cities. HP highlights some of the companies (and professionals) behind the innovation driving sustainability. For example, utilizing a system that can handle a building’s electrical distribution overload while saving the owner/ developer money and energy… we’ve got that covered! Check out page 12.
USGBC MA Events for 2016-17
Companies like Advanced Energy Intelligence offer cities, college campuses and property owners the ability to track energy usage, eventually allowing the owner/facility manager to understand how, when and where the energy is being used or wasted. Check out the energy map of Boston on page 11. Most of us know what L.E.E.D. certified means… but what about WELL certified? Jennifer Taranto of StructureTone explains it nicely on page 9. You’ll also read about a corporate campus that has seven LEED gold buildings, an elementary school that is considered a “vision leader” and a design firm such as Maugel Architects, who transformed Laddawn Headquarters into a creative, functional space while making sustainability a priority. Enjoy the supplement. Feel free to share any comments or thoughts with me at Anastasia@high-profile.com. Thank you for reading,

Kern Center to be Self-Sustaining Designed by Bruner/Cott Amherst, MA – The recently completed $7.1 million, 17,000sf R.W. Kern Center at Hampshire College is about much more than making a good impression on prospective students. Designed by Bruner/ Cott & Associates to be entirely selfsustaining and meet the Living Status of the Living Building Challenge, the center aims to make a lasting impression on all who enter by demonstrating Hampshire’s commitment to a sustainable future and inspiring the next generation of leaders in environmentally conscious practices. The building is sited to present itself to visitors upon arrival to Hampshire’s campus and serves as a welcome center for staff, students, and their families. The central floor-to-ceiling glass pavilion maintains a connection to the outdoors and serves as a hub of campus activity with a common area, community living room, and café on the ground floor and gallery above. Two stone-clad wings house admissions and financial aid offices and classrooms with views of the amphitheater, rainwater harvesting reservoirs, solar farm, and wildflower meadow. With a solar canopy to generate electricity, the rainwater harvesting system for net-zero water, and open, exposed walls in the mechanical rooms, the building itself serves as a learning and teaching laboratory. Daily tours and signage give students and visitors the opportunity to participate in collecting and analyzing data regarding green building practices. New classes are built around the teaching opportunities the living building makes available, inspiring the kind of inquiry and stewardship

embodied in Hampshire’s philosophy of contributing to knowledge, justice, and positive change in the world. Selected from over 40 entries in a design competition, the plan rerouted a corporate campus drive, replaced it with the wildflower meadow, and created a human-centered landscape with the Kern Center as the new heart of the campus. Using local stone and wood, the building emphasizes the importance of the relationship between indoors, and the plaza and landscaping around the building encourages people to enjoy being outside and around the building, not just inside it. All building materials are Red List compliant, avoiding products made with toxic chemicals, to make the center the healthiest possible working and learning environment for students and staff. The project team included: construction manager, Wright Builders; electrical engineer, RW Sullivan; geotechnical engineer, O’Reilly, Talbot & Okun Associates; landscape architect, Richard Burke Associates; lighting designer, Lewis Lighting Design; mechanical engineer, Kohler & Lewis Engineers; and structural engineer, Foley Buhl Roberts & Associates.

UConn’s NextGen Hall Cultivates Innovation Storrs, CT – Next Generation Connecticut is a $1.5 billion initiative to increase educational opportunities, research, and innovation in the science, technology, engineering, and math (STEM) disciplines at UConn over the next 10 years. In addition to being the first oncampus housing facility built in 13 years, NextGen Hall is the first project that was awarded and completed under the Next Generation Connecticut program. The building was designed to foster academic success, innovation, and community building, including the Learning Community Innovation Zone makerspace. The new $105-million complex, which opened in August 2016, is a 210,000sf, eight-story, 727 bed residence hall with seminar rooms and an innovation zone laboratory for students’ use. The project was designed for LEED Silver certification. BVH Integrated Services, P.C. served as the design engineer during the bridging documents phase, and continued on throughout the project as UConn’s design consultant during the completion of the design and the construction phases, which included commissioning services for the project. Newman Architects was the bridging design architect and the university’s design consultant during the construction phase, and KBE Building Corporation served as

the design-builder and constructor for the project. The building is heated by three highefficiency gas-fired condensing boilers. The terminal equipment was designed to operate at lower water temperatures, in order for the boilers to operate in condensing mode, and at their highest efficiency throughout the heating season. Cooling is provided by two water-cooled centrifugal chillers, with an open cooling tower on the roof. The cooling tower sumps are located inside the building, so that condenser water is available immedi-
ately when needed during swing seasons. The residence rooms are heated and cooled by two-pipe valence units. These are units that use natural convection to quietly heat and cool the spaces without needing electric fans or filters to move the air. In addition, each room has an operable window. When the windows are opened, the cooling is disabled. A signal is sent to the building management system through a contact on the window, so the rooms can be monitored and protected from freezing if a window is inadvertently left open in the winter. Reclaimed water from the campus
central reclaimed water facility plant is being used for flushing of water closets and for make-up water for the cooling tower. The system is estimated to save about 19,000 gallons per day of water during peak use days. With the reclaimed water use, low-flow plumbing fixtures, and no permanent irrigation system for plantings, water use will be reduced 50% from the LEED baseline. Domestic hot water is produced by 45 roof-mounted solar collectors that preheat approximately 2,850 gallons of hot water storage for peak periods. Supplemental heat is provided only as needed by seven high efficiency condensing instantaneous gas-fired water heaters. The thermal solar collectors are expected to provide up to about 30% of the building’s domestic hot water. The building envelope includes high efficiency glazing. The building was scanned with infra-red cameras and spray water tested to correct potential water/air leakage and minimize infiltration. Other energy saving features include energy recovery wheels on the exhaust systems, LED lighting, a partial green roof, and dashboard displays to promote energy savings. The projected energy savings for this building is 29% above the LEED/ASHRAE baseline.
From civil, structural, mechanical, electrical, plumbing, and fire protection engineering services to sustainable design, commissioning, and technology design, BVH integrates people and disciplines together. As thousands of successful buildings, structures, and complex campuses show, BVH brings it all together to create a better project.

Concrete Masonry Is Sustainable ground finishes are subtler, and split units give a rugged “rock-like” feel. With a wide range of materials, textures, and colors available, the design possibilities of CMU are endless. What makes masonry sustainable?
by Heidi Jandris and Jennifer Wagner
Editor’s Note: This text is part one of a two-part series article. Most designers know that masonry is inherently a green building material. Masonry has many attributes that contribute to its sustainability including protection against rot, mold, and termites. Greater resilience translates into lower maintenance costs and reduced use of virgin materials. Masonry’s strength and ability to withstand severe weather and fire are helping to meet new demands for climate-resistant building materials. Moreover, concrete masonry’s (CMU) thermal mass benefits can reduce energy bills and improve thermal comfort in buildings. CMU has come a long way, since the term “cinder block” was coined, and there are many aesthetic options for both structural CMU and non-structural veneers. A polished CMU gives a contemporary, sleek look, where matte
Masonry is strong, resilient, durable, sound-reducing, and beautiful. One of the most important sustainable ability to absorb and store heat. In the northeast, the best way to utilize thermal mass is to help hold the temperature of conditioned spaces. The energy code recognizes the benefits of thermal mass. In the 2012
IECC, for climate zone 5, the prescriptive requirement for a mass wall is a U-factor of 0.078 (R-11.4). Comparing this to a wood framed assembly, which has a U-factor requirement of 0.064 (R-20), or to a metal building with a U-factor requirement of 0.052 (R-26), utilizing thermal mass reduces the amount of wall insulation required. Methods to improve masonry’s sustainability
CMU has a lower cement content than other concrete, since it gains additional strength through vibration and compaction. In addition, the environmental footprint can be reduced further using supplementary cementitious materials, or SCMs. One commonly used SCM in the northeast is slag, a byproduct from steel production.
design, which has helped identify potential inefficiencies in their operations.
The next frontier in sustainability: sequestered CO2
In March 2015, Jandris installed CarbonCure’s CO2 recycling technology into their Gardner, MA plant. Jandris is among 36 concrete producers across Canada and the US that is using this innovative technology to make better building products. CarbonCure’s technology recycles CO2 from smokestacks and injects it into masonry during mixing, where it gets converted

Description of the CarbonCure process where calcium from the cement reacts with carbonate from the CO2 to form solid calcium carbonate (similar to limestone).
Many CMU producers are looking for ways to go above and beyond designer’s expectations by introducing new elements of sustainability into their manufacturing practices. Committed to taking a leadership role, Jandris has made several changes to their manufacturing process over the last decade, which has improved plant efficiency and lowered their environmental impact. They utilize use thermal mass to cool the facility, have lowered their kiln oil consumption by half and introduced a closed loop system in their wet finishing facility to conserve water. Since installing solar panels, they have offset CO2 emissions by 949 tons. Jandris has also upgraded their manufacturing process to consume less Portland cement while maintaining required CMU strengths, further lowering CO2 emissions. Jandris has also invested in developing 3rd party verified EPDs for each mix

views of the surrounding context. Sustainability was a key design consideration for the project. Particular attention was given to conserve resources and reduce the environmental impact. Recyclable building materials and low-emitting paints, adhesives and flooring were a top priority. To conserve energy, walls of windows provide abundant daylight to the open offices areas, break rooms, climbing wall area and lobby. LED light fixtures, interior occupancy sensors, and full cutoff
exterior dark-sky approved luminaires were also installed to conserve energy and minimize light pollution. High efficiency plumbing fixtures were specified to reduce wastewater generation and potable water demand. To encourage alternative transportation, interior bike storage was located on the “Main Street” thoroughfare.

Penn Brook Elementary Wins LEED
Georgetown, MA – The Penn Brook Elementary School recently received LEED Silver certification, the first building in the town to achieve this goal. Drummey Rosane Anderson (DRA) is the architect of the new three-story elementary school that is designed for 770 students in kindergarten through sixth grade. “The School in the Woods,” as the new Penn Brook School has been dubbed, allows spaces throughout the interior to have views to the surrounding site. The fresh air system allows notification to classroom teachers via a green light when the outside temperature and humidity levels are appropriate for opening windows, thus reducing the amount of energy required by the HVAC equipment in the classroom wing. These units are zoned for east and west exposure for this portion of the building. Operable windows are in every classroom to allow students and teachers to aid in the energy-saving process. Toilet rooms in the student wing utilize recycled rainwater from the roof above. The rainwater collection system
and pump are in the boiler room, which is fed from the 7,000-gallon tank onsite that holds the water for reuse. Rainwater from the cafetorium roof is collected in a rain garden and flows to an underground cistern used to water student gardens. These gardens are currently maintained from springtime through the fall by students attending the elementary school. The gardens are integrated in the main play area that also has porous pavement to minimize rainwater runoff from the developed portion of the site. This reduces the impervious paved area considerably and allows for a large play surface on the south side of the building. Photovoltaic panels are mounted on the south side of the cafetorium roof. The design meets 1% of the overall building energy load from equipment. The school also has preferred parking for energy-efficient and low-emitting vehicles. The elementary school was completed in the fall of 2015 and the students are now enjoying their new, sustainable “School in the Woods”.

The WELL Building Standard is a relatively new building rating system that measures the performance of a building as it relates to the occupant’s health and well-being. In short, where LEED cares about the health of the planet, WELL cares about the health of the people in the built environment. As LEED made strides to transform the market, sustainability practitioners often talked about the perceived improved productivity of employees and the reduced absenteeism. These outcomes, which were secondary to carbon reduction, were, at best, observations discerned from clients, but without any formidable proof until now. Harvard recently released a study finding that carbon dioxide (CO2) has a direct negative impact on cognitive ability, thus proving that productivity really is better in green buildings with better indoor air quality.
Here is where WELL enters the picture. The WELL Building Standard dovetails neatly where LEED leaves off by including features that specifically address the occupants and are backed up by science and medical evidence. It addresses the quality of the air, water, food, and light within a space while at the same time guiding companies on policies related to fitness, comfort, and mental well-being. A company’s largest expense is its staff, which can come close to nearly 90% of
the costs of any business. Because of this, as noted in a 2013 World Green Building Council study, any improvements made in indoor air quality have a far greater return on investment than cuts to energy usage. Those improvements to indoor air quality improve the productivity of your employees, reduce absenteeism and — more importantly — increase presenteeism. Those improvements to
your employees’ performance will far outweigh the improvements in energy performance, which account for a 1% to 3% savings. Make no mistake; this is not a call to ignore energy efficiency and replace it with wellness initiatives, but rather a call to action to supplement your carbon reduction goals with improvements to your employees’ health. In this market, there is a war on talent. Employers want the best and brightest workforce to push research forward on new pharmaceuticals, the best coders to create new software, and the brightest attorneys to help people and businesses do the right thing. The question they’ll ask is, “Why should I work for your firm?” The WELL Building Standard allows companies to cite specific, tangible examples to help answer that question. Through our discussions with clients about the WELL Building Standard, we have heard that the rating system has allowed them to put their arms around disjointed efforts and budget allocations among various departments to speak with a unified, clear voice about the benefits these efforts offer to existing and new talent. WELL has brought multiple departments, previously working in silos, to the table to improve the potential health outcomes for everyone.
Achieving WELL certification for your project will create an integrated project team. Achieving WELL certification for your project will create an integrated project team. There are features that require alterations to the built environment, those that require alterations in facilities maintenance, and those that will require organizational policy changes as well as added incentives for employees. Furthermore the features are field tested and verified so that you can point to third-party scientific test results showing the quality of the air, water, light, and acoustics in your space. We are experiencing this collaborative effect firsthand as we seek WELL certification for our own new Manhattan office and plan to share more lessons from that process as we move forward. In the meantime, learn more about becoming WELL certified at wellcertified.com. Jennifer Taranto, LEED AP ID+C, BD+C, WELL AP, is director of sustainability at Structure Tone.

AEI Delivers Energy Map of Boston Boston – Advanced Energy Intelligence LLC (AEI) of Carlisle, has delivered an energy map explorer that shows energy and water usage in the city of Boston for over 450 buildings and 15 million sf in the Boston public schools, fire department, police department, public library, and public works. The explorer is available online at www.aeintelligence.com/city-ofboston. AEI developed this visualization as a demonstration of how it will deliver similar results for other cities, towns, and property portfolios so that administrators and facility managers can comprehensively explore their energy usage. Working with its partner, Guardian Energy Management Solutions, AEI is developing this model for the specific towns covered by recently awarded Green Communities funding. Compatibility with a wide range of data sources including Green Button, MEI, and EPO, and building automation system data from Siemens, Honeywell, JCI, SkySpark, and many others, makes it easy to deploy for other towns, campuses, and large property portfolios. The map provides a comprehensive energy exploration tool that is vital for understanding portfoliowide usage
and costs that can drive discussions with utilities, aggregators, and facility managers. Owners and facility managers can learn how their buildings stack up against the DOE and Energy Star national averages, by commodity, season, and facility type. Ranking facilities by EUI, per sf, and costs helps target resources to the energy-efficiency opportunities with the best ROI. The energy map is a consistent entry point into facility details such as billing records, building automation system (BAS) data and analytics, utility interval data, and peak demand analytics. With daily and weekly updates, it’s an O&M view at the facility level that can help facility managers react to weather, occupancy, and variables at the HVAC level. Support for widget integration with
town websites can help drive awareness and social behavior at a high level, with trouble-ticket support at the individual facility level. Chip Goudreau, Director at Guardian said “Teaming up with AEI puts us in position to offer our Green Communities customers something they haven’t had - a comprehensive and interactive view of their energy and water usage. With AEI’s forward-thinking work, it will be easier for us to demonstrate the savings from our energy projects and help the towns quantify those savings back to DOER. In the 2016 grant application, DOER made a specific request for energy data analytics as a way to measure sustainability goals and achievements, and we believe the work of AEI will go well beyond delivering on that objective”. Carl Popolo, founding partner of AEI, adds, “Our core work focuses on building energy-efficiency, but we also realized that property managers need a better way to decide which projects should come first. By bringing together a wide range of data sources and purpose-driven analytics, we think those managers are better served when there’s a more comprehensive and standard way to quantify the baselines and the opportunities. This is a logical
entry point into the more detailed work that we do at individual buildings.” In the city of Boston map, over 700,000 utility records and the 5-minute electric interval data for many of the facilities allows a wide range of constituencies — from facility managers to the general public — to quickly understand how individual buildings compare to each other in terms of energy use. The integration of 5-minute electric utility interval data also helps a facility understand how their utility demand charges are calculated and how they might defend their facilities against the impending ISO peak hour that will determine their capacity charge for next year. Adam Jacobs, energy manager for the city of Boston, was instrumental in helping AEI qualify the city’s data sets. He said, “We think Boston is on the cutting edge in terms of delivering open data to the public, and those in a position to add insight to the raw numbers can provide real value back to the community. Work like this by AEI is what we have in mind when we deliver the city’s data to a public forum as part of its Boston’s Open Government program.”

Network Drive Burlington Campus Achieves Seven LEED EBOM Gold
by Daniel Whittet
Network Drive is a commercial office center located in Burlington, Massachusetts originally developed as a campus for the computer software company Sun Microsystems in 1997. Currently owned by Network Drive Owner LLC, there are now seven office buildings sharing close to 1 million sf of office and research space supporting high-tech companies with a combined central utility plant centered on 114 acres of land. The LEED project boundary encompasses 80 acres of landscaped grounds and hardscape close to the buildings creating the campus, which is surrounded by 34 acres of native conservation land. Originally conceived by Sun Microsystems in the late ’90s to have the look and feel of a university campus, the project was a natural fit for the LEED Campus approach to certification. This method allows buildings to take credit for shared attributes on a site and achieves separate LEED certification for each

project, building space, or group. As part of the LEED attempt, Network Drive management worked with AHA Consulting Engineers to benchmark and initiate several innovative approaches to improving the campus environment while reducing energy and resource consumption. A completely new front end to the original building operation system was completed with a recommissioning and upgrade of controls. Parking lot lighting was converted to LEDs with a Zigbee Mesh Network control system that allows pinpoint management of site lighting to reduce energy consumption and light pollution while improving safety.

was reduced 30% in buildings and 75% on the landscape irrigation. Transportation options were implemented that included a bike-sharing service and regular shuttle initiatives to reduce conventional commuting trips by 31%. The connected landscape and walkways of the site allowed the project to receive credit for sustainable food purchases at the centrally located Sebastians café. The spacious dining facility uses organic local produce and seafood from Reds Best, a local networked seafood provider. A project with Green City Growers also allows tenants to get fresh produce from raised-bed gardens onsite, which contrib-
uted to a LEED Pilot credit, and the waste diversion policy includes composting of all food waste at an offsite location. The LEED project team was able to use the building automation system upgrade to initiate a monitoring-based ongoing commissioning plan that includes fault testing algorithms and system optimization. A flat plate heat exchanger in the central plant provides free cooling for intensive data center spaces during winter months. The comprehensive LEED EBOM rating system involves a performance period during which project team members initiate plans, policies, benchmarking, and recommissioning of building assets to upgrade properties and the environment around them. “LEED for Existing Buildings Operation and Maintenance (EBOM) is a challenging and time-consuming process,” stated Patrick O’Neill, assistant vice president of Nordblom Management Company. “We feel the outstanding success of the Network Drive certifications is a testament to the quality of the original design and the commitment of the management team to continuous improvement.” All the buildings have been awarded LEED EBOM Gold with Energy Star scores above 80. Daniel Whittet, LEED AP, is a sustainability consultant at AHA Consulting Engineers.

Sights on 2030: Early-Stage Energy Modeling for High-Impact Results
by Victoria Rybl and Ian Robinson
Architecture 2030’s “2030 Challenge” has laid out an ambitious target of achieving net-zero operating carbon emissions in all new buildings and major renovations by the year 2030. Lofty initiatives relating to climate change are nothing new to the building industry. However, as initiatives like the 2030 Challenge achieve widespread adoption by code officials, compliance with such targets is bringing about radical changes in the design process. Critical, early-stage design decisions such as building form, envelope properties, and HVAC system selection can no longer be made without assessing their energy impact. The imperative to design ever-more-efficient buildings has made it crucial to engage energy modelers as part of the design teams very early in the process. Defining success: “How good is good enough?”
Deciding what metrics to use and what
performance target to design is the first step in any energy-informed design process. Both the metric and the target will be unique to the project. LEED (and often building owners) require energy cost as a metric. The Massachusetts Stretch Code uses site or source energy consumption. The 2030 Challenge uses net greenhouse gas emissions. Optimizing for one metric or another can lead to vastly different design decisions. Which metrics are most relevant to a given project and what the targeted performance should be is determined by what hurdles that specific project needs to clear. However, thoughtfully choosing a metric and striving towards a target is fundamental. Establishing the target early in the process and defining that target as a design requirement will help ensure all parties are focusing their efforts on a desired end result. Value-add modeling in early design: “Now what?”
Energy modelers often struggle to produce meaningful results in early-stage modeling due to the absence of concrete details. It is exceedingly difficult (and time-consuming) to produce model after model while major design elements are in flux. However, with well-documented assumptions and modern energy modeling tools, it is possible to make
valid determinations and guide the design team towards positive outcomes. Issues that have the most impact include: • Massing options. • Glazing and envelope options. • HVAC systems. • Targets for internal gains (occupancy, lighting, plug loads). As if optimizing each component individually weren’t complex enough, design decisions regarding each separate item can also impact the optimal choice for each of the others. At this stage, it is important to simplify the model and use time-efficient tools to minimize modeling time and allow a maximum number of energy modeling runs. With simplified models, the team can perform dozens, or even hundreds of simulations to yield a true sensitivity analysis for each design variable. Sensitivity analyses assess the impact of major design elements on energy performance in multiple scenarios. For instance, what impact does changing
the average lighting power density have on building energy usage if the façade is well-insulated and the HVAC is a chilledbeam system? What if the building is lightly insulated and the HVAC is VAV? Frequently, the answer in one scenario is very different from the other. By assessing design decisions holistically, we develop a more accurate picture of how each decision impacts the overall project. Using the outcomes of early-stage modeling, the team can make decisions that optimize energy usage and first costs without any guesswork. Equipped with this knowledge, the design team can move into the detailed design stage with clear direction regarding energy performance. Owners and architects can have confidence that each individual piece of the puzzle will contribute to the bigger picture, meeting its energy-related goals. Victoria Rybl is an energy engineer.

Bloomfield, CT – At the annual Green Building Awards Celebration of the Connecticut Green Building Council (CTGBC) on September 22, the New Haven chapter of the ACE Mentor Program of Connecticut received the Student Project Award of Honor for its project, River Street Resiliency District. This project addresses rising sea levels and increased storm frequency, two aspects of climate change that are affecting Connecticut’s shoreline directly. As part of the annual CIRT-ACE National Design Competition, the students worked with mentors to respond to a “Shoreline Design Challenge” and master-planned 10 blocks of the Fair Haven neighborhood, which sits at the convergence of Long Island Sound, the Mill River, and the Quinnipiac River. The students chose this historic site due to its history of flooding and erosion damage. Additionally, the students addressed the social aspects of revitalizing this culturally significant neighborhood. By
developing diagrams, visiting the site, and researching historical data, the students were able to design solutions for three zones: the historic district, buffer zone, and flood zone.

Daylighting Interior Athletic Spaces: the Middlebury College Solution
by Leslie DelleFave
At Middlebury College, the ARC/ Architectural Resources Cambridge design team tackled this challenge and developed an innovative approach to achieve the critical lighting balance needed. The college’s LEED Platinumcertified Squash Center includes nine international-sized squash courts, tiered spectator seating, a student fitness area, entry lobby, and offices.
The design team carefully studied options with the goal of lighting the entire spectator area with daylighting though a large central light well. We set out to design a feature in the space that would delineate the spectator area from the squash courts, utilize daylighting to minimize energy loads on the facility, and create a unique viewing environment that took advantage of the quality of light that natural daylight provides We challenged ourselves to remove all other light sources and to rely instead on a single skylight element designed to provide all spectator lighting. The spectator area is daylit using a light well, topped with a skylight, with a layer of diffusing horizontal glass providing an even light level and eliminating direct sunlight distractions to the athletes. The solution utilizes a combination of LED lighting, daylight color matching, and daylight dimming so that day or night, cloudy or bright, this light well remains a
consistent light source. By matching the color temperature of natural light via LED lighting controls, we provided a consistent level of natural light and ensured that no direct sunlight permeated the interior of the squash courts. In addition to the aesthetic and athletic benefits, the design factors into meeting the college’s goals for sustainability and contributes to achieving a significant

energy reduction, in keeping with the LEED Platinum certification objectives. Post-occupancy data in the first year of operation showed a 35% improvement in EUI based on the AIA 2030 CBECS baseline and a 50.4% cost energy savings based on LEED guidelines. Leslie DelleFave, AIA, LEED AP, is an associate with Boston-based ARC/ Architectural Resources Cambridge.
Creating a natural balance of daylit and supplementary interior lighting is a challenge in most buildings and presents a distinct dilemma in athletic and sports facilities. In spaces hosting sports competitions, an imbalanced lighting environment for even a short time can distract athletes and impair performance, often causing an unfair advantage to one side. The ideal scenario, a consistent design that works in harmony with everchanging exterior conditions, requires a careful evaluation of options and desired outcomes.
New Fusions in Design
An Integration of Planning, Architecture, Landscape Architecture and Interior Architecture Wednesday, November 16, 8:00 a.m. - 9:30 a.m. Boston Convention and Exhibition Center Room 160A
French Dam Prototype Complete North Billerica, MA – French Development Enterprises, LLC (FDE) of North Billerica; GEI Consultants of Woburn; and Oldcastle Precast of Littleton, Colo., recently announced the construction and assembly of the first prototype French dam — modular precast impoundment for construction and retrofit of hydroelectric dams, water control systems, and power houses. The 24-ft. long x 16-ft. high prototype, designed by GEI Consultants in cooperation with Oldcastle Precast, consists of six 27,000-lb. concrete 8-ft. x 8-ft. blocks interconnected with each other forming one monolithic structure. Upon arriving from Oldcastle’s plant in Avon, Conn., the dam was assembled in less than 3.5 hours. FDE’s patented technology for rapid
dam construction was funded for $1.7 million in January 2016 by the United States Department of Energy (U.S. DOE) under funding opportunity “Research and Development of Innovative Technologies for Low Impact Hydropower Development” (DE-FOA-0001286). The construction of the prototype of the modular hydro dam comes three months after the U.S. DOE released its Hydropower VISION report, which recommended modular approaches to new in-stream hydropower facilities. In this report, the U.S. DOE proposes a “suite of modular components for foundation, generation and stream passage may be considered and fit together to meet site-specific parameters as well as environmental and power generation objectives.”
