Mini Series: 5 PHitW Highlights

May 10th, 2010 by Tim Delhey Eian

This week we’ll embark on a little mini-series, highlighting 5 reasons why the Passive House in the Woods project is a sustainable project.

The leapfrog design of the Passive House in the Woods is based on integrated design and the holistic idea of building and living. Gary approached us with a vision of carbon-neutral, low impact building. That in itself does not sound like much. But we quickly realized how serious he is about it, and embraced the idea by assembling and leading a team of experts to deliver on all fronts of sustainability.

Highlight #1: Low Energy Footprint and Carbon Emissions:

We chose Passive House design—the world’s leading building energy standard—to create a building envelope that is extremely efficient to begin with. It is, in fact so efficient, that even in climate zone 7 it can be heated with two hair-dryers on the coldest, darkest days of winter. The energy model we created shows a predicted energy consumption of 4,200 kWh per year. This will be offset by a 4.7 kW photovoltaic system, generating an average of 6,750 kWh per year—making the building net energy positive (makes more energy that it consumes), and delivering carbon-neutral operation for two people in the home.
