Imagine a house that keeps itself warm in the wintertime. Think of the savings in terms of fuel bills and unfriendly emissions. Such houses in fact exist, called “passive houses”. The concept of these highly energy-efficient buildings took root in the 1990s, before slowly consolidating as a niche construction (生态位构建) concept in the 2000s. Are passive houses now actively moving into the mainstream as sustainable buildings?
For Brian Mc Garry, an economics lecturer who built a family house based on passive housing criteria in the Pyrenees this year, the arguments look convincing. As his first full winter in the low energy house draws in, we asked him to keep us informed. Do passive houses work?
I had never heard of a passive house in February 2012, when I purchased a plot of land. Nor did I expect that I would be persuaded to build a pre-constructed, custom-designed house based on energy-efficient passive house criteria. It promised to be easier and quicker to build, cheaper to run, and more comfortable to live in. The objective was to incorporate the fundamental concepts of passive energy management into my project: an airtight and highly insulated building envelope; large south facing double or triple-glazed windows (if possible, filled with argon gas) that passively capture the energy of the sun; a heat recovery ventilation system to provide fresh air; and a simple, low-cost heating system consisting of a modern wood-burning stove, a bathroom heater and a portable radiator backup for when the sun doesn’t shine and temperatures decline. No significant limitations were placed on the design, and it had excellent environmental credentials. Moreover, the cost was no more than a conventional build.
After six months in use, the house is proving to be both cheap to run and remarkably comfortable–staying cool in the hot summer was effortless, as long as the windows were shuttered or shaded from the sun. Nowstaying warm in the cold, high-altitude December climate also seems easy, so far.
Winter arrived in force in the Pyrenees in November, with abundant snowfalls and temperatures as low as minus 8° Celsius. Though early days, the house has responded well: the stove is lit during cold evenings but the portable radiator has not yet been needed. This type of construction seems not only to make economic and environmental sense, but to enhance our quality of life, too.
