Heat Recovery Ventilator
The model P variable-speed HRV from Greentek is included in the baseline performance specs of the home and in an optional upgraded model to help achieve a LEED for Homes rating. The ventilator recovers heat from exhausted indoor air and transfers it to fresh air coming into the house to enhance indoor air quality and reduce heating energy costs. The unit attaches to the air blower and meets ASHRAE minimum continuous flow (CFM) standards. 888.724.5211. www.greentek.ca.
Windows
High-performance windows from Marvin meet a complex set of requirements. In addition to adhering to a historic aesthetic, the casement, single-hung, and fixed units also had to meet energy-efficiency standards, facilitate passive heating and ventilation, and capture views to enhance livability and comfort. The windows feature a low-E coating and argon-filled airspace between the two panes of glass, resulting in a U-factor of 0.33 and a climate-appropriate solar-heat gain coefficient for Energy Star and LEED for Homes qualification. The units also contain percentages of recycled wood, glass, and aluminum cladding. 888.537.7828. www.marvin.com.
