Energy and sustainability

From development to operations, WinnCompanies embraces environmentally responsible decisions. We are proud to be a national leader in green development and the utilization of renewable energy.  

Our innovative approach and leadership in sustainability are recognized throughout the multi-family industry, while our award-winning green projects demonstrate our commitment to excellence — and to the planet.

Green Building Certification 

Following certification best practices — such as the U.S. Green Building Council's LEED for Homes and Enterprise Green Communities as well as Energy Star ratings — WinnDevelopment is leading by example. All WinnCompanies acquisition rehabs and new developments embrace sustainability principles and integrate the best solutions for each particular development.  

Our recent LEED Platinum Certification at Oliver Lofts (Boston's only mid-rise, multi-family redevelopment to earn this distinction) demonstrates a 21st century approach to historic preservation.

Deep Energy Retrofits 

WinnDevelopment and the Castle Square Tenants Organization recently completed the nation's largest "deep energy retrofit," saving over 50% of the building's energy usage.  

Through significant support from many partners, including the U.S. Department of Housing and Urban Development's Green Retrofit Program and the Massachusetts Department of Energy Resources, Castle Square has utilized the most advanced building science to guide the renovation of a 500-unit affordable-housing complex in one of Boston's premier neighborhoods.

Solar Power 

Over the last decade, WinnDevelopment has led the multi-family industry in solar power development. With over one megawatt of PV installed on affordable housing, WinnCompanies has transformed rooftops into power plants. By utilizing state and federal incentives, solar-electricity and hot-water installations stabilize property utility expenses while reducing dependence on fossil fuels and achieving clean-energy policies. 

Expanding on this experience, Winn has committed to installing an additional four megawatts of solar PV to benefit affordable housing by 2020.

Better Buildings Challenge

With over 40 million square feet of real estate under management, WinnCompanies is constantly improving the efficiency of building systems, including mechanical, lighting and envelope upgrades. We have partnered with the U.S. Department of Housing and Urban Development, the Department of Energy, and numerous local and state energy groups to weatherize as many properties as possible across 23 states and Washington, D.C.. Together, we have focused on insulation, air sealing, boilers, ventilation, air conditioning and water conservation.

In 2013, WinnCompanies became a US Department of Energy Better Buildings Challenge partner, committing to saving 20% energy usage across its portfolio within the next decade. 

Green Financing

Recognizing that future energy savings can be used as a revenue stream to pay for sustainability upgrades, WinnCompanies has been working with national leaders to define effective models to finance energy improvements in affordable multi-family housing. In 2010 and 2011 WinnCompanies and Enterprise Community Partners piloted a $1 million energy loan program, used to upgrade energy systems at a 307-unit apartment community in Massachusetts. 

Operations and Maintenance

In 2010 WinnResidential expanded its commitment to furthering green-building principles by developing company-wide green-operations policies. These policies, which follow the framework of the U.S. Green Building Council's LEED for Existing Buildings, aim to ensure integration of energy-efficiency and sustainability best practices into the entire WinnCompanies affordable-housing portfolio.
