You know it is going to get Hotter!
There are so many articles out there about global climate change. Along with climate change comes the inevitable. Longer hotter summers! One way that we might be able to adapt better in the future is to construct homes and other buildings with super insulation to meet the need of keeping us cool during the hottest times. As an added benefit it will keep us warm in the winter! One of the construction techniques comes from the Passive House concept. Read on and see if any of this makes sense to you.
Passivhaus in Europe
Thick walls, thick roofs, and triple-glazed windows
Most European Passivhaus buildings have wall and roof R-values ranging from 38 to 60. Wood-framed buildings usually have 16-inch-thick double-stud walls or walls framed with deep vertical I-joists. Masonry buildings are usually insulated with at least 10 inches of exterior rigid foam. To meet the Passivhaus window standard, manufacturers in Germany, Austria, and Sweden produce windows with foam-insulated frames and argon-filled triple-glazing with two low-e coatings.
Although the Passivhaus Institut recommends that window area and orientation be optimized for passive solar gain, the institute’s engineers have concluded, based on computer modeling and field monitoring, that passive solar details are far less important than airtightness and insulation R-value.
Passivehouse in the United States
Imagine having a home that was neutral to heating and cooling. Where Air transfer with a heat pump was all that was necessary to keep an even temperature in a larger home…Cool huh? or Warm depending on what season you were in!
If you want to spend the extra money for increased insulation and wall widths knowing that you will make it up in utility bill savings, a Passive House is the way to go.
