Lindenguild Hall: A Contemporary Approach to PV in Green Affordable Housing

Written by Katie Schwamb


Katie Schwamb, one of the project’s contributing sustainability consultants

The Lantern Organization’s Lindenguild Hall is a 104-unit multifamily residential project that provides permanent shelter for under-served populations in the Bronx. On-site supportive service programming, open-use learning and activity rooms, and outdoor leisure space provide an enriched living experience for tenants. Contributing to the programmatic requirements of both LEED® for Homes™ and NYSERDA’s Multifamily Performance Program (MPP), the building’s sustainable and energy-efficient design features include high-efficiency boilers, a high-performance envelope assembly, low-emission finishes, low-flow plumbing fixtures, and a water-efficient landscaping and irrigation system. While all of these design elements contribute synergistically to high-performance operation, there is one feature that distinguishes Lindenguild Hall from many other affordable and supportive housing projects in New York…its extensive photovoltaic (PV) array.

Located on the building’s high-albedo roof, this 66-module solar electric array captures energy to help power lighting, heating, and cooling systems within the building’s common spaces, while reducing overall demand on the city’s electrical grid. An advanced feature of Lindenguild Hall’s PV system is its capacity for online monitoring, which provides building managers with real-time results, including metrics for solar generation in kW (kilowatts) and the overall kWh (kilowatt-hours) generated to date. Availability of this data enables management to assess the positive impact of renewable energy systems on their building’s performance. Long-term implications of alternative energy production on building stock include reduced life-cycle cost and protection against municipal energy uncertainties. Though less quantifiable , installation of innovative green technology adds momentum to standardizing sustainability in affordable housing design.

Lantern Organization, a not-for-profit housing developer and service provider, operates by actively addressing housing needs and offering social initiatives to strengthen disadvantaged NYC communities. SWA’s Residential Green and Multifamily New Construction groups helped Lindenguild Hall navigate the LEED for Homes program and secure NYSERDA MPP incentive funds. Committed to delivering the greatest benefit to their residents, Lantern acknowledges the added value of incorporating green building features into their affordable projects. Increased energy efficiency and improved indoor air quality potentially translate to lower energy cost burden and decreased susceptibility to disease for low-income populations.

HUD’s 2015 IAH Graduate Student Design Competition: SWA Supported


HUD’s 2015 Innovation in Affordable Housing student design and planning competition has hit full stride. Building on its successful inaugural run in 2014, this year’s competition has university representation from over 20 states. Strategic teams of 3-5 graduate students and a faculty advisor, primarily from architecture, urban planning, real estate, business, and environmental engineering programs, are challenged with redesigning a 300-unit senior housing property for the Houma-Terrebonne Housing Authority (HTHA). Competitors will craft actionable solutions that consider economic, social, and ecologic issues unique to the region’s affordable senior housing sector. Successful projects will address needs of senior residents (quality of life), site and building codes, finance strategies (incl. leveraging partnerships), integrated energy efficiency technology, and community connectivity. Following a rigorous review process, select finalists will travel to Houma, LA in March for a site-visit intended to prepare competitors for refining their final submission. The winning entry will be chosen by a judging panel of industry thought-leaders, and awarded $20,000 at a ceremony in Washington, DC ($10,000 to the runner-up).

Steven Winter Associates, Inc. (SWA) recognizes the critical need for global availability of quality, affordable housing. Our support of HUD’s competition will advance studies in this emerging market by initiating a new generation of student-professionals into the industry. SWA fulfilled a lead role in competition development, outlining the competitive structure, project submission requirements and guidelines, and final judging criteria. Additionally, SWA spearheaded all marketing efforts for the competition, including a robust registration outreach campaign consisting of email blasts, phone communication, social media, and direct mailing. Work on the IAH competition demonstrates the firm’s continued support of student and professional competitions, adding to past programming efforts with the SBIC’s Beyond Green™ High Performance Building Awards and the Housing Authority of Norwalk’s Affordable Housing Design Competition. The firm’s involvement reinforces SWA’s commitment to progressing innovation in high performance building practices, and validates SWA’s reputation as an industry authority on sustainable multifamily building science.

SWA’s Tips for Giving the Gift of Green

It’s the most wonderful time of the year! We asked a few of our green living gurus if they could share some tips on how we can reduce our environmental impact this holiday season:


  • Turn off your Christmas tree during the day. – Celeste M.
  • Use LED lights, and put them on timers. – Gayathri V.


  • Compost your leftovers from dinner. Celeste M.
  • Shop locally and bring your own tote bags to reduce packaging waste. I highly recommend local breweries and local farms. – Karla D.


  • Make sure to unplug chargers, lamps, and other miscellaneous appliances when not in use. Always unplug electronics as soon as they are fully charged; never leave rechargeable electronics plugged into power when they are fully charged. Your brand new holiday gadgets as well as your electricity bill will thank you! – Carmel P.
  • Use rechargeable batteries in new toys. – Jordana V.


  • Use recycled paper for wrapping. – Celeste M.
  • Recycle gift wrapping. – Jordana V.
  • Buy gifts without much packaging. – Jordana V.

Notes from Abroad: A SWArrior in Sweden

In October, NESEA awarded SWA’s Heather Nolen with a travel scholarship through the Kate Goldstein Fund for Emerging Professionals (you can read the announcement here). Heather joined four other scholarship recipients for a two week  journey to Denmark and Sweden to explore  innovative sustainability methods being used in their buildings. The following is blog entry written by Heather, describing her experience at a location outside of Stockholm. (This entry was reblogged from NESEA’s blog; you can find the original post here.)

We met with Björn Cederquist who was kind enough to tell us about Hammarby Sjöstad, a new sustainable district, which he is quite proud of.

Stockholm is a growing city, with a population of 1.5 million and a serious lack of housing. The city central is quite developed, outside the city there are the typical suburbs, it is the area between the city proper and the suburbs that Stockholm is looking to develop in a planned, sustainable manner. To meet the city’s housing needs Stockholm plans to construct 8,000 units per year, mind you they have only been building at 5,000 units/year of maximum. This is a large undertaking for the city which is being planned in a thoughtful way.

Despite the need for more units of housing there is a strong tradition in Stockholm of midrise buildings which accounts for the reluctance to build higher. Hammarby Sjöstad is mostly mid-rise with one exception, a single 12 story building.

Located in this prime area between the city and suburbs, Hammarby Sjöstad is located at an old harbor and landfill turned Brownfield site. To convert this piece of land into a residential community public transportation had to be extended, both the subway and train lines. The presence of transit shows a commitment to the area, a feeling of permanence which is required to build the community. 80% of residents commute by public transit.

To meet sustainability goals in a comprehensive way the district aimed to be a healthy place for people to live that stimulates the body and soul with opportunities for exercise, sports and culture. Design began in 1990 to construct an “Environmental and Ecological City District,” which includes 11,000 units housing over 25,000 people; an additional 10,000 are projected to work within this area. In addition to the housing and transit systems, power plants were constructed to provide district heating and cooling, waste removal including organic waste, public water supply and wastewater treatment.

Renewable energy sources, harvesting of energy from the areas wastewater system, burning of waste combustibles along with harvesting energy from the sewage system allow Hammarby Sjöstad to operate their CHP plant free of fossil fuels. Central heat pumps at the district plant operate year round to extract energy which allows for district cooling, planned for 10 years the plant is the largest in the world. The wastewater treatment plant harvests both bio-gas and bio-solids. Bio-gas is used to power buses, taxis and some individual stoves. Bio-solids are used as fertilizer in forest, filling mines and soon to be used for agriculture purposed. Combined with advanced waste collection and energy efficient construction Hammarby Sjöstad is a unique community which is a product of long-term planning and collaboration. Sites underdevelopment are learning from Ham Hammarby Sjöstad to further advance eco-districts for long-term success.


Where is it now: Greenbuild’s LivingHome

We’ve talked about this conference already this month, but we couldn’t leave out one of the coolest parts that one of our own SWArriors, Maureen Mahle, got to participate in – a modular green home assembled on the showroom floor at the 2014 Greenbuild Conference and Expo. SWA is a partner of the Greenbuild LivingHome which was created in collaboration with Hanley Wood, LivingHomes, Make it Right, and the International Cradle To Cradle Products Innovation Institute. This show home, which Greenbuild attendees got to tour, achieves an array of lofty goals that enable it to be supremely sustainable both for the environment and its owners.

Greenbuild LivingHome, led by California-based designer of green modular home, is the result of a unique integrated design process, utilizing designers, vendors, and building science know-how from all over the country. Today, vendors are using the home as an opportunity to showcase the latest and greatest in residential green building products, including Cradle to Cradle certified products and Forest Stewardship Council certified woods.

One of the stand-out LEED® features of the home is the commitment to durable, resilient construction. Other site features include:

  • Permeable paving to maintain an almost permeable lot for managing stormwater.
  • Framing was treated for pest resistance.
  • Termite barriers installed at base plates, and a non-toxic termite bait system surrounding the home.
  • Closed cell foam, used to insulate the elevated floor.
  • Continuous drainage plane directs bulk water down and away.

So where is the home now?
On its site in the Lower 9th Ward in NOLA, owned by the Make it Right Foundation, contributing to the city’s growing stock of green affordable housing. Make it Right is working to complete the home for occupancy in the next few weeks!
