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.

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!

Survey says.. Feedback is Fundamental.

While commissioning and utility metering provide quantitative building performance data, post-occupancy surveying qualitatively gauges tenant awareness, understanding, and appreciation of green features. Forego this step, and you miss a critical opportunity to engage end-users in the green building experience.

Recently, SWA launched an initiative to collect post-occupancy evaluations from certified projects. University Village on Colvin (LEED® for Homes™ Gold-certified, Syracuse off-campus housing) was the first to participate.

Key Survey Findings from University Village Residents:
• 94% of respondents reported being conscious of energy and water conservation
• 77% of respondents were satisfied with the green features of the buildings. Green features were defined as those that save energy, water and natural resources, and promote indoor environmental quality.
• Favorite green features among the respondents were: air conditioning, recycling accessibility, low-flow shower and aerator, and ENERGY STAR® appliances
• 94% of respondents reported satisfaction with the general building site maintenance

Surveying is an essential touch-point coupling building, management, and resident. It forces both stakeholder groups to assess their relationship with the sustainably built environment. At University Village, tenants took stock of their green living area, assigned a personal value to green features, and considered ecological impacts of their behavior. In turn, property managers can discern how their investment translates to improved quality of life, which elements of their investment carry added marketability for luring prospective tenants, and how residents interact with green features to either maximize or minimize their usefulness.

Post-occupancy surveying humanizes green building through education and exposure, demystifying what would otherwise be overly esoteric or easily overlooked technology. In an industry largely under-discussed by a green-ho public, a simple measure that improves accessibility and relatability of green building is invaluable to mainstreaming our beloved practice.
