Allentown Square Net Zero Multifamily Apartment Building
C.J. Brown Energy is the NYSERDA Low-rise Residential New Construction Program Partner and the registered EPA ENERGY STAR Homes HERS Rater for Allentown Square Apartments at Maryland Place, a new $7 million, three-story, 52,500 sf, “net zero” apartment building with 58 market rate apartments aimed at lower- to middle-income residents. It is one of the first “net zero” multifamily buildings in Buffalo.
As the NYSERDA LRNC Program Partner-Rater, C.J. Brown Energy has provided design guidance, building energy modeling, and installation verification and testing services for the project. The project was originally conceived in 2011 as “Casa Serena,” a $4 million 53-unit affordable housing development to be designed and constructed to meet NYSERDA’s “Tier 1 – EPA v3.0” incentive program. The project was renamed and revised in 2015 to meet NYSERDA’s “Tier 3 – Net Zero EPA v3.1” incentive program.
Each of the units has its own high efficiency condensing boiler and on-demand water heating system, LED lighting and ENERGY STAR appliances. The project was designed with BATT insulation in the wall cavity along with continuous insulation around the entire building, and high performance windows and doors, as well as electric-vehicle charging stations. There are 552 solar panels on the roof and carport to achieve a Net Zero HERS index.
The project is also located on a former brownfield site. Construction began in 2015 following a months-long cleanup involving excavation and disposal of about 3,600 tons of soil and fill materials, and installation of a soil cover and vapor barrier.
