DATA
- Climate zones in the USA
- Design Temperatures from ASHRAE
- National Solar Radiation Database including
viewer from which you can view a map and download data
explanation of data provided from the viewer does not seem to exist, but is probably the same as in the downloads for computation. - Database of Thermal and Optical Properties of Glazing Products, IGSDB . You need an account to sign in.
- ColoradoEnergy.org list of R values for materials.
- GHG Emission Factors Hub, with downloadable spreadsheets giving tons of CO2 generation per BTU of fuel or kWh of Electricity for every region of the country (different ISOs). Useful for calculating CO2 saved from installing solar.
- For Heating Degree Days and historical weather, use NOAA.gov
