I am not talking about solar power generation. Quite the contrary.
Passive solar is about building design and orientation. One of the techniques it uses is thermal mass.
- dismalpedigree 6y agoI’d love to know the all-in energy and ecological footprint of building for passive solar. I could imagine it is significant. Sure you save lots of energy over its lifetime but you likely have a huge deficit to start with.
- DoreenMichele 6y agoI doubt that, but I will add a link to this comment to my file and see if I can find anything when I get around to trying to do some kind of write up about it.
- throw0101a 6y agoCompletely passive buildings are a thing: * https://en.wikipedia.org/wiki/Passive_house https://en.wikipedia.org/wiki/Passive_house Though generally one gets to a point of diminishing returns. It's probably better to get to a certain efficiency point, and then throw some solar/PV panels on the roof and become 'net zero', producing the electricity you need on-site: * https://en.wikipedia.org/wiki/Zero-energy_building https://en.wikipedia.org/wiki/Zero-energy_building Residentially, you can built a 5000 square foot (500 sq. m) home that needs only 1500W (1.5 kW)—basically a hair dyer—to heat/cool: * https://www.youtube.com/watch?v=_vul4vMFdkA https://www.youtube.com/watch?v=_vul4vMFdkA Using an HRV/ERV with an air filter per ASHRAE 62.1 and 62.2 gives you very good air quality.
