Observations (Part 02)

Mill Creek NetZero Home, December 15, 2009, 14:00.

As we approach the winter solstice and the three-month anniversary of our moving in, we continue to learn about our new house. These observations are mostly qualitative, because we don’t have the rest of our solar modules up, and we haven’t set up monitoring equipment yet. We are tentatively planning to remove the door of our wood stove on July 1st, 2010  and then monitor the house’s energy use for a year.  read more... »

Ventilation

Mill Creek NetZero Home Heat Recovery Ventilator

I heard a story once about a man who built a house using insulated concrete forms (ICFs). While I don't advocate their use in general, ICFs have some distinct advantages (certainly over conventional construction). The primary of these advantages is supreme air tightness. ICF homes (those that are built with ICFs from top to bottom) can achieve hourly air change rates of 0.2. In contrast, the Mill Creek NetZero Home has an airtightness measurement of 0.36 ACH, which is really amazing for a wood-framed house.

So back to this guy who built the ICF house. He apparently wasn't aware of how air tight his house was, or at least the consequence of that air tightness. Six months after he moved in, he had to rip all of the drywall out because it had rotted. He had built a house as tight as a plastic bag, and forgotten a critical aspect: ventilation.  read more... »

Belgravia NetZero - Introduction

You may have heard about Edmonton's next net-zero house, particularly if you're on Gordon Howell's mailing list. The Belgravia net-zero house is under construction, with demolition of the the previous house (built in 1948) on June 30.

Hi, my name is Bob Heath, and I'm the owner of the Belgravia NetZero (BNZ) house. I'd like to thank Conrad for allowing me to post to the Green Edmonton site. I'll be posting frequently over the next year about various aspects of the house, but I thought I'd devote my first post to how I came to make the decision to build a net-zero house.  read more... »
