What U and SHGC is needed in temperate weather conditions to achieve NetZero?
In this wonderful community, Energy Efficiency is often been in reference cold climates. I live in California and am in the architectural stages of building a NetZero house.
We have two seasons: Summer and Rainy. The rainy season lasts from November to end of Feb and during those months it can actually freeze – although I doubt if we ever have more than 5-6 freeze days a year. In the summer we never have more than 5-6 days above 90 in a year. We probably have at least 330 days of sunshine.
So all in all, pretty temperate weather – although regardless of the season it does cool down in the evening – even summers require sweaters in the evening. We do have wonderful weather – but it is not the weather I am writing about but what kinds of U factor and SHGC should I be looking for in windows as I try to achieve NetZero.
Of course I am going to do roof over hangs on the south side but should I be looking for the same U and SHGC on the windows on all sides of the house? I assume not. Is there any enlightenment anyone would be willing to share with me? When it comes to walls I am trying to achieve an R-30
