- roywiggins 5y agoYeah, they've looked into using this tech for roofs and things: https://www.sciencemag.org/news/2014/11/new-way-cool https://www.sciencemag.org/news/2014/11/new-way-cool
- TuringNYC 5y agoI see how this would be useful in always-warm/hot environments. But I'm curious -- would this be useful at locations with major seasonal changes? For example, in northeastern USA, the temperature varies from 100F to 0F through the year. So this would be great in the summer, but do I just "pay" for it in the winter via more heating? I imagine it depends on the cost of heating vs cost of cooling depending on the location.
- peteradio 5y agoWhere it gets cold, a single family home would tend to have snow cover anyway.
- mrfusion 5y agoI think the idea is that the attic tries to maintain ambient outdoor temperature and the house is then insulated from the attic. So you may not get much heating from your roof in the winter anyway. Someone correct me if I’m wrong.
