Oh I’m totally with you! There is a long and storied history of passive design strategies, and exterior shading is one of the oldest ones out there!
But what I stated is plainly true, and many people simply don’t want exterior shades (or just don’t think about it).
The point I was trying to make was just that there are thermal implications to the orientation, and you should think those through (using thermal simulations can help detect these issues) and come up with appropriate strategies (thermal simulations can help validate them). Maybe you don’t want shades, but you would be okay with emissivity coatings for your windows. Or maybe you just want to position windows on both sides of the home with continuous air volumes connecting them to promote natural ventilation. Maybe you can take advantage of thermal mass. The list goes on…
- PaulDavisThe1st 2y agoI was not describing exterior shading. The terminology is hard. I was describing overhangs that create shade during the summer.
- szvsw 2y agoOverhangs are considered exterior shading in the industry/practice/academia. Any obstruction that prevents solar gains by blocking radiation from entering the window falls within the general category of external shading, whether that’s a fancy high tech actuated shading system, a grille, a simple awning, a structural overhang, vertical fins, etc.
- PaulDavisThe1st 2y agoA structural overhand is viewed by homeowners as something utterly different from everything else you've mentioned there.
