NHPF Gaining Ground By GoingGreen

Bayview Towers + Eversource Bayview Towers affordable housing community of 200 one-to four-bedroom apartments in Stamford, CT partnered with Eversource which provided energy-saving upgrades at the property and is serving as a model for other energy-saving efficiencies across our portfolio. NHPF looked for ways to improve the overall property, increase the comfort of each apartment, and help residents save on their energy costs. Eversource and Energize Connecticut provided technical and nancial assistance to make the energy-saving upgrades at Bayview Towers. Through the Multifamily Initiative, Eversource worked with The NHP Foundation’s selected contractors, CMC Energy Services, Inc. and New England Mechanical Services, Inc., to create a comprehensive agreement outlining the eligible measures, implementation costs, and the energy savings that would result from the improvements. The improvements included: • C hanging inefficient lighting to high-efficiency LED lighting throughout the entire complex, including the living spaces, common areas, and exterior spaces • W eatherization measures, including air sealing around doors and windows and other air leaks in the building envelope • R eplacement of boilers with new energy-efficient as a family-friendly property, the interior and exterior lighting upgrades have also made a dramatic difference in the brightness, reliability and security of shared common areas, parking lots, and the outdoor playground. The weatherization and lighting upgrades to each apartment, and the updating of the heating system’s boilers and equipment provided residents and property staff with increased safety and comfort. The 2019 gas and electricity usage was –34% and –4% lower when compared to baseline (2014). These very favorable usage results generated approximately $85k in savings which will be put in use this year to improve playground fencing, upgrade the current security camera system, and other property related projects.
