Passive House Alliance Elects Its First President: Sam Hagerman of Hammer & Hand

The new national organization, established by the Passive House Institute US to build the Passive House green building movement in North America, selected Hagerman to help realize its promotional and public education mission.

Portland, Ore.—Nov. 10, 2010—Sam Hagerman, President of local contractor Hammer & Hand, was elected President of the Passive House Alliance at the 5th North American Passive House Conference this past weekend.  The Passive House Alliance (PHA) is a new national organization established by the Passive House Institute US (PHIUS) to promote, market and educate about the Passive House building standard.  Hagerman is joined on the PHA Board of Directors by such building industry luminaries as Kent Adcock, President and CEO of Habitat for Humanity of Washington, DC.

“The Passive House Alliance represents the next logical step for the expansion of the most rigorous, building-science-based sustainable building standard,” says Hagerman.  “The Alliance will fill a critical role in leading the promotion, marketing and consumer education necessary to bring the benefits of Passive House to a wider public.”

What Is Passive House?

A Passive House (or Passivhaus in Europe) is a structure that employs a simple set of building technologies to achieve tremendous energy efficiency; energy consumption is reduced by 90% compared to conventional buildings. The standard emphasizes simplicity over complexity. Unlike with LEED, Passive House projects do not chase a list of ‘green’ points. Instead the focus is on actual, measured energy performance. How much energy is required to build and operate a structure?

Passive House homes minimize energy losses and maximize passive energy gains by employing seven principles:

1.   Super-insulate.

2.   Eliminate “thermal bridges” (that allow heat and cool to travel through walls).

3.   Make the building envelope airtight.

4.   Use energy and heat recovery ventilation.

5.   Use high performance windows and doors.

6.   Optimize passive-solar and internal heat gains.

7.   Model energy gains and losses using Passive House computer modeling.

The results are impressive. In Portland’s climate, all heating needs can be met by a single 1000-watt heater (equivalent to heating a home with a hair dryer).  Lights, appliances, and building occupants provide all other needed heat.
