ZED’s Needham Residence will be open to the public.

88% better performance than a new house built to code!

Saturday, 10AM to 4PM | Needham, MA
Street Address in profile here:

ZED Staff members will be on site. The home is still under construction, please wear appropriate shoes.

This NSTAR sponsored Deep Energy Retrofit includes a super-insulation strategy (R-71 Roof, R-45 Walls, R-26 Foundation, R-17 Slab, and U-0.22 Windows) combined with aggressive air sealing, a high efficiency air source heat pump, heat recovery ventilation, and 8 kW of solar electric.

The resulting home yields exceptional energy performance with a HERS index of 12, making it roughly 88% better performance than a new code-built home, and targeting net zero energy.
