Where's the Heat, Part II






The snow's melting. The sun is out, coming through the windows. Oops, but not in this house above. Where are the south facing  windows to radiate that warm sun? A lot of Btu's of heat will come in during these moderate days if the home is properly designed. What happened? The house wasn't planned for the site.  Put aside the asthetics of a big wall with no windows. No windows will also make this home a darker for about half of the day for the rooms on the inside. They will only pick up natural light from the east and west part of the day. Free light, free heat, all rejected due to its design.

This house below faces south as well. It's design responds to the site. Nicely proportioned windows. Not a wall of glass, but nice sized windows for the rooms indoors. They'll get a good amount of heat from the sun when it's needed (fall, winter, spring). The trees and overhangs will work to keep the sun out during the summer months. The other benefits of the overhangs is that they will keep the water away from those windows. So if these windows aren't flashed perfectly, the overhang will keep the house dry. They have worked well on this home for over a century.





The lessons: Make sure the house is oriented on it's site properly, that it's designed for the site. Take advantage of the sun for heat and light. Use overhangs and awnings to keep the sun out and keep the house dry. This is solar heating at its best. This is the part of Green Building that is free and has a big benefit.
