  •  Here's the phrase: The house is planned (15+ / 0-)

    a lot of these efforts take good planning.  A well designed structure can do a lot to cool and heat itself simply by using the environment.  I think we could do with more of that, some by providing resources, some by improving planning and building codes.  I'm drawn to some of the successes with the passivhaus and Zero energy building approaches.

    There's a lot of simple things we could do if we only wanted to.

    •  An ancient and simple city planning idea (1+ / 0-)

      that Hot climates tended to gravitate to if not planned is to NOT have north south/East West street grids but have them at 45 degrees from that... SE to NW & SW to NE...

      This automatically adds more shade throughout the day and keeps buildings and streets cooler in the summer in more equatorial regions where the sun is more directly overhead while in the winter more walls are in direct sunlight a bit more to keep the building a little warmer...

      it can be seen in places like downtown LA... the old street pattern is from the Spanish colonial time... the rest of LA in the flat areas switches to a North South/East-West layout A Northern European Legacy... While it is true that the older European street grids are all over the place... when they got organized and did city planning the prime compass point layout just seemed the way to go...

      But East West streets have the northern side bake all day in the Summer... while the southern side freezes all winter... The "Spanish" (& North African, Arab way too) spreads the heat load around better and exposure to direct sun is minimized for most wall surfaces in the summer while a slightly lower sun in Winter (at those latitudes) actually exposes walls to more solar energy overall... and of course all the walls are white anyway so the main point was reduced exposure and reflectivity..

      A bit too late to change existing layouts in the hotter regions... and while in the Northern parts of the US it used to not get as hot as it has been in recent years the northern European style grid
