The Science of Lab Design

By Bob Laurence, Manager of Energy Efficiency, Eversource


Northeastern University’s new Interdisciplinary Science and Engineering Complex (ISEC) features 234,000 square feet of space that houses a vibrant interdisciplinary research community. The six-story complex is mixed with labs and classrooms organized around one central atrium.

It’s also a really cool building. And, you don’t need a microscope to see the state-of-the-art design and energy-efficient technologies. 

The university worked collaboratively with Eversource and the design team to identify energy-saving measures and technical expertise to jump start the project. Then, they explored financial resources available through the Mass Save program. Armed with energy-efficient recommendations, architecture firm Payette, engineering firm Arup, and general contractor Suffolk Construction then worked together to bring this stunning building to life.

In fact, ISEC is designed to use 75 percent less energy than a typical intensive research building. Let’s uncover the science of this innovative lab design and its technologies.


• Climate responsive building envelope – The complex is equipped with triple-glazed windows, which reduce glass condensation and prevent heat loss. ISEC also features sun-shading aluminum “fins” to maximize daylight penetration while minimizing heat gain. This basically means a huge comfort boost for students and faculty inside the building—while the university saves on energy costs.

• Variable Air Volume (VAV) fume hoods – While a fume hood may be the most important safety feature in a lab, it’s also a big energy user. Labs use tremendous volumes of exhaust to flush out potentially hazardous fumes. Northeastern added high-performance VAV hoods, which exhaust the amount of air required to maintain a safe velocity setpoint. They also reduce the hood’s supply fan speed and maintain the desired temperature and humidity. Simply put, VAVs maximize safety while minimizing energy consumption.

• Enhanced airside systems – Many labs have a dedicated HVAC system, which can often be expensive to operate. ISEC boasts a cascade system that recovers conditioned air from its offices and atrium, then transfers the air to the labs to save energy and costs. In fact, an approximate 50 percent reduction in energy use over baseline building standards is expected, thanks to this highefficiency cascade approach to recirculating warm and cooled air.  


• Occupancy-based airflow controls – Many older labs with low fume-hood counts operate at 10 air changes per hour (ACH) or above, 24 hours a day. Northeastern’s new VAV fume hoods and added airflow controls will reduce its lab ventilation rates from 6 ACH to 4 ACH whenever labs and equipment room spaces are detected to be unoccupied.  

As an added bonus, ISEC is also on track for LEED Gold Certification. Visit www.northeastern.edu/isec to learn more about the building.

“A Building and a Landscape Should Work Together”

By USGBC Communications

Levi + Wong Design Associates (LWDA) have embraces an approach to landscape architecture that is grounded in holistic observation. LWDA creates healing gardens, courtyards, and campuses that bring landscape and building together. The firm's mission? Design with purpose, solve spatial problems with imagination, and implement solutions that are both beautiful and sustainable. LWDA works in harmony with existing natural conditions so that building and landscape work together.



The firm is able to unite building and landscape to serve as extensions of one another, creating smooth transitions between indoor and outdoor spaces.

For example, the adult day living courtyard at Braintree Rehabilitation Hospital was inspired from an idea to use the outdoors as an extension of the hospital’s physical therapy program. A former overgrown and little-used side entrance yard was transformed into a new garden that integrates everyday outdoor activities into a patient’s rehabilitation The garden now serves multiple functions including therapy, meditative, and family gathering, and the space successfully mixes patients, families and caregivers in an equitable outdoor environment. A variety of New England pavement types, sidewalks curbs, garden gates and latches, and ramps become activities patients can use to rehab and relearn everyday outdoor living: mailboxes, benches, curbs, curb ramps, outdoor handrails, plant potting, basketball, and miniature golf. Offering comfortable venues of outdoor seating and rehabilitation activities, the garden has become the centerpiece of the hospital.

The Walden Pond Visitor Center Earns LEED Gold

By USGBC Communications

This month marked the 200th Anniversary of Henry David Thoreau's birthday, and in sync with this anniversary, the new, netzero Walden Pond Visitor Center in Concord, MA has earned LEED Gold Certification.  The new facility will house interactive exhibits on writer, Henry David Thoreau, and a film about Walden Pond.  

 


The LEED Gold Walden Pond Visitor Center, Concord, MA.

The visitor center – a project that's been 40 years in the making – includes a high-performance exterior envelope; energy-efficient heating and cooling systems; landscaping that mimics the natural habitat, as well as wood grown and processed in Massachusetts. The A/E team anticipates the design will provide a 48% reduction in energy costs and 37% reduction in water consumption compared to baseline building.

The new state-of-the-art Walden Pond Visitor Center welcomes guests from around the world to the state reservation. Walden Pond State Reservation, which is a National Historic Landmark, was made internationally known because of the literary works of naturalist Henry David Thoreau. Thoreau, who wrote ‘Walden; or, Life in the Woods’, which reflects on his time spent over the course of two years, two months, and two days in a cabin he built near Walden Pond, inspired the land conservation movement in the United States. To this day, Walden Pond State Reservation remains a heavily used state park with a popular public swimming beach, as well as other outdoor recreational opportunities such as hiking, boating, and fishing.

The new Walden Pond State Reservation Visitor Center features:

  • 5,680 net square feet, approximately two-thirds of which will be dedicated to publicly available interpretive displays related to the life and legacy of Henry David Thoreau;
  • A south-facing orientation providing a wood and glass façade to maximize solar efficiency;
  • Superinsulation with increased roof, wall, and window values to conserve energy;
  • A 9 kilowatt (kW) solar hot water system;
  • A Variable Refrigerant Flow heat pump system;
  • A low flow plumbing system to reduce water consumption; and,
  • A 100 kW solar canopy array in an adjacent parking lot that will generate more than enough clean renewable power over the course of a year for the visitor center.

Congratulations, The Green Engineer (USGBC MA Chapter Sponsor), on the achievements of this wonderful project!

Mixed Use Comes Of Age

By USGBC Communications


How can architecture re-imagine how mixed-use developments can meet changing demands and preferences?

Mixed use is not a new idea. Retail, office, and residential have long co-existed side by side in cities and towns, but there is little doubt projects are becoming more unique and more comprehensively planned. Creating a community and a destination is the new emphasis, and transportation, whether in the form of parking for private vehicles, access to public transportation, or usually both, is a priority.

On the Boston waterfront, The Architectural Team Inc. combined new construction and adaptive reuse at Lovejoy Wharf. Now home to the corporate headquarters for clothing manufacturer Converse, the complex also offers retail space, a recording studio, and outdoor public amenities like a 30,000-sq.-ft. wharf space along the water’s edge. (Photo: Gustav Hoiland)

Jay Szymanski, AIA, NCARB, LEED AP, associate at The Architectural Team, Inc. shares his thoughts on how mixed-use projects are expanding in cities as well as suburbs: he stresses the importance of access to a wide range of jobs, goods, services, and opportunities for social interactions as keys for “successful 24/7 live, work, play environments.”

He expands with lessons for all mixed-use developments:
“Ideally, a development should provide enough critical mass to support several uses that keep activity on a site at all times of the day and all days of the week. The inclusion of quality outdoor space that allows a variety of different passive and active options will help support retail, commercial, and residential uses. Inclusion of some food service uses will serve the residents, as well as the general public. The addition of some form of public art, whether it be a sculptural element or a water feature, certainly helps to serve as an attraction to bring in activity and local pride and an attachment to one’s community. Its importance cannot be overstated.”

The expectations of building owners, tenants, and visitors to mixed-use neighborhoods clearly have evolved. No doubt adjustments will continue to be required as needs and preferences mature, making those plans that are the most flexible the ones that will be the most successful.

HouseZero under construction at Harvard University

By Jen Cole


Harvard is striving for excellence in the green building industry, as they just announced that their next project will be retrofitting a 1940s stick-built house that will be used for their headquarters. The new house is projected to use no HVAC system, no electric light use during the day, 100% ventilation, almost zero energy, and produce zero carbon emissions, including embodied energy of materials. Before now, this level of efficiency was only being achieved in new construction projects, making this HouseZero Project the first-of-its-kind.

Inefficient existing buildings are one of the nation's biggest energy problems and Harvard is setting a precedent on the possibilities in a retrofit that can be replicated almost anywhere. HouseZero not only reduces the demand for energy but also saves money for property owners by significantly lowering operating costs.

The plan is to replace the current HVAC system with thermal mass, and a ground source heat pump for peak (extreme) conditions. A solar vent will instigate buoyancy-driven ventilation and triple-glazed windows will employ natural cross ventilation through a manual and automated system that monitors for temperature, humidity, and air quality. Much like a layered approach to clothing, the house is meant to adjust itself seasonally, and even daily, to reach thermal comfort targets. Construction for this project will take about 7-9 months; check back in at the end of the year for new photos and updates.

Embedding Sustainable Design into Design Process

By USGBC Communications

USGBC MA Chapter Sponsor, Levi + Wong Design Associates set an example for how to incorporate sustainable design into all aspects of design practice. Over half of the professional staff is LEED accredited, and as a whole, the firm believes sustainability is not an “added value” to otherwise conventional projects, but rather a thought process embedded in every step of project design.


From site design to envelope analysis to daylighting studies to material selection, Levi + Wong Design projects embrace a holistic approach to systems and materials.  The firm offers clients a proactive, research-based, budget-conscious approach aimed at delivering cost-effective, maintenance-friendly, healthy buildings.  

The firm considers short term performance metrics such as daylight harvesting, total energy consumption and water use, as well as the long term impacts of potential future expansion and infrastructure replacement. To Levi + Wong Design, sustainability is really just another term for good, common sense design, employing materials and systems that minimize waste, maximize performance and deliver the best value over the life of the project. 

 


An example of this holistic approach is exemplified by The D’Youville Center for Advanced Therapy in Lowell, MA. The 25,000 square foot state-of-the-art facility is designed for a single site experience that supports the needs of patients across the continuum of care.

To promote healing and wellness, natural light permeates through windows strategically located in corridors, patient rooms and therapy spaces drawing light into interior spaces. The large windows views in the rehabilitation gym create a connection with the local neighborhood and exterior courtyards allow patients access to outdoors relaxation and community re-entry training experiences. A clean modern look was created using simple forms, detailing, and proportion, and was complimented with natural materials such as wood and stone to create spaces that are warm and comfortable.

Sustaining a Community – Uphams Crossing

By USGBC Communications


What’s the best way to redevelop a prominent site in the business district of a community that sorely needs housing options? In the case of the former St. Kevin’s Parish in Dorchester, Mass., the answer was the creation of a mixed-income residential campus called Uphams Crossing, a development integrating adaptive re-use and new construction into the uniquely landscaped existing parish grounds. With the creative financial stewardship of the Planning Office of Urban Affairs (POUA), safe and affordable housing has been delivered to the Upham’s Corner community.

Dorchester is one of Boston’s largest and most vibrant and diverse neighborhoods. But it also has a history as one of the city’s most distressed. More than 20 percent of its residents live near the poverty line, and it has one of the highest foreclosure rates in the area. The St. Kevin’s site in the heart of Dorchester’s business dis-trict, known as Upham’s Corner, presented an ideal location to create a mixed-income residential complex. POUA led an innovative project team that could address the housing issue through a creative vision for serving the Dorchester community.

The result is a mixed-income complex with 60 units of workforce housing for people who contribute to the local economy, such as teachers, technicians and service industry workers. Additionally, 20 units of permanent affordable housing were set aside for formerly homeless individuals or families. Supporting the residential units is a full-time onsite manager, as well as office space for St. Mary’s Center for Women and Children, an onsite provider of supportive services. A multi-use community room was designed to provide space for resident programs and hosting neighborhood community meetings. All of these services are centrally located in a spacious common area that also holds two resident lounges, an exercise room, computer learning center, bike storage and a central laundry.

Uphams Crossing is within walking distance of convenient public transit with multiple city bus lines and the Upham’s Corner commuter rail. New housing here opens up numerous opportunities for residents, making it easier to engage with the commercial heart of Dorchester and bringing people closer to necessary services. At the project’s grand opening, Boston Mayor Marty Walsh described Uphams Crossing as “a place that serves a compassionate, value-driven community. One of the great things about Boston,” he continued, “is it preserves its past and prepares for its future.” The project team couldn’t agree more.

For 45 years, the architecture, masterplanning and interior design firm, The Architectural Team, Inc. (TAT), has been recognized for its thought leadership, diverse portfolio of acclaimed design solutions and creating lasting transformation in the communities they serve. The 90-person firm has earned more than 100 awards for design excellence across a broad range of building types and programs; including: new construction of large-scale urban mixed use developments, multifamily, commercial, waterfront and hospitality developments, assisted and senior living facilities, and community centers. TAT also holds a national reputation in the areas of historic preservation, rehabilitation and adaptive reuse that has transformed neighborhoods across the United States, artfully restoring and reimagining neglected buildings for new uses while simultaneously preserving history.

Congratulations to TAT, USGBC MA Chapter Sponsor, on this wonderful project!

Bringing LEED Platinum Projects to the Seaport

By USGBCMA Communications


Boston's Seaport District has experienced a burst of development in recent years, which has brought over 5,000 new jobs to the area and catalyzed over $1 billion in investment since 2010. One of the first major buildings to break ground and begin transforming the Seaport skyline was 101 Seaport, a $126 million, 440,000-square foot, 17-story glass office tower. On board for this massive construction project was RDK Engineers, a full-service engineering and design firm and USGBC MA Chapter Sponsor.

RDK provides a variety of engineering services in energy efficiency and sustainable design for almost every building type. The firm has helped shaped sustainable development in Boston's Seaport District by helping 101 Seaport achieve LEED Platinum, the highest LEED rating level possible. Over 20% of RDK staff members are LEED Accredited, and whether or not RDK's clients choose to pursue LEED Certification, the firm continually assesses projects to improve efficiency in project MEP/FP (mechanical, electrical, plumbing/fire protection) systems. 101 Seaport is the first completed office building in Seaport Square, a 23-acre master-planned area in the city’s fastest-growing neighborhood. 

101 Seaport Boulevard achieved LEED certification for implementing practical and measurable strategies and solutions aimed at achieving high performance in sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality. Owner Union Investment Real Estate GmbH oversaw a range of strategies and solutions put in place, from heat island reduction and stormwater quantity control to water-efficient landscaping and a green cleaning policy. One of the major differentiators of energy efficiency at 101 Seaport Boulevard is the mechanical system designed to cool the building through use of an active chilled beam, a cutting-edge system that is the first of its kind in Boston.

For former Mayor Thomas Menino, 101 Seaport served as a significant step forward for the Seaport and for the City of Boston. At the groundbreaking, then-Mayor Menino celebrated the project announcing, “This project secures the neighborhood’s reputation as a hub for entrepreneurs and forward-thinking companies to expand, and for our residents to enjoy. 101 Seaport, and its anchor tenant in PwC, represents the leadership in innovation, sustainability, and business that have become synonymous with the City of Boston and our business community.”
