Gallery: Hudson Passive Project Becomes First Certified Passive House i...

A rendering of the Hudson Passive Project.

In order to achieve Passive House certification you have to build a very well insulated home that is virtually air tight and heated primarily by the sun and from the people inside. A large south facing wall lets the sun come through a set of Serious Windows (725 Series), and skylights bring more daylight into the rest of the home. The walls are insulted with 12 3/4″ EPS foam (R50), the roof uses 12 1/4″ Neopor SIPs (R53) and the foundation is an insulated concrete slab on layers of gravel, EPS, and XPS (R60).

Upon achieving its certification, the Hudson Valley Project also set a record for air-tightness with a score of 0.149 ACH at 50 Pascals and reduces its heating consumption by 90 percent. A Zehnder ComfoAir heat recovery ventilator brings in fresh air while minimizing heat loss. Two Mitsubishi Mr. Slim heat pumps (SEER 23 and 26) and three Cadet electronic baseboard heaters provide the heating and cooling. As expected, all the appliances are Energy Star rated.

The three bedroom, two bathroom tallies up to 1,568 square feet and was designed to blend into its surroundings, reflecting the rural atmosphere of the Hudson Valley Area. The high performance home does not have any solar photovoltaic system, solar hot water, or wind turbines. It relies on its design for its energy efficiency. According to Jetson Green, the home cost $250-300 per square foot.

    Cograts to the Hudson VAlley pProject and prinsipals.
    One comment: There should be water managment also; and likely a large warm-water reservoir to be solar heated. Only one WSHP would be needed.
    Most likely, the required reservoirs could be under a future house like this, or under a 2-car garage / workshop.
