New York’s First Net Zero Apartment Complex

net zero apartment complexOn May 15th Newport Ventures staff visited New York States first Net Zero apartment development. Known as NetZero Village, the units located in Rotterdam, NY are expected to produce more energy than they consume on a yearly basis. These units are ENERGY STAR and EPA Indoor AirPLUS certified.

The 3-story buildings are enclosed with R-45 on the flat roof using a combination of rigid foam panels and closed cell spray foam, R-30 in the walls consisting of zip panels, 1/2” continuous rigid foam and 3.5” of closed cell foam and 2” of rigid foam under the slab with 3” of rigid foam on the edge. This high level commitment to the building shell has achieved early blower door results in the ≤ 1.0 ACH, which is very impressive for a building with net zero apartment complex 1common walls.

The HVAC system for each apartment consists of one mini-split head installed over the entrance door to each unit with the heat pump wall mounted on the backside of the building. The HRV supply side opening is located in front of the mini-split to promote air mixture while the mini split is operational. Small back up electric strip heaters are located in each bedroom if needed.

The hot water for each 6 unit building is generated from 7 solar collectors that transfer heat to one -700 gallon site built storage tank located in the first floor mechanical room. This pre-heated water passes through one of 2 electric water heaters when there is a demand.

Some of the key components to achieving Net Zero:

  • Solar Panels mounted on top of all the Carports
  • Solar thermal mounted on top of the buildings
  • 100% LED installed lighting
  • Energy Star Appliances
  • All of the buildings face South

Other technologies that Net Zero Village is incorporating include:

HRV supply side vent located in front of the mini-split to prohrvmote the mixture of conditioned air.

Coils delivered on site ready for hook up and immersion into the 700 gallon water storage container. Fluids in these coils will circulate back up to the roof to capture heat form the sun 365 days a year.

Carports throughout the development are covered in solar electric panels estimated to produce more energy than the entire complex will actually need on a year to year basis.
