PASSIVHAUS 101: Sustainable Architecture from the Inside Out
This article discusses the Passive House (PH) as an example for sustainable architecture. It defines what a PH house is as well as how it uses shading, ventilation, and solar power efficiently. Originating from the efforts of German physicist Wolfgang Feist, the word Passivhaus, or Passive House, is a term that de- fines a building’s energy use for heating. For the purposes of this discussion, a PH is one that does not use over 15 kWh/m2/yr.
Let’s look at an example. In the wintertime, let’s say it is –15° C with a flow of about 15 watts per hour per square meter of heat energy escaping the building. At –2° C, around 7.5 watts per hour of energy loss would be expected. At the same time, the building would have energy inputs— for instance, through heating, cooking, charging stations for computers, and, not to be forgotten, the heat that human bodies emites […]
