Building modeling software for solar shading in different European countries.
The solar shading industry has developed software tools to illustrate how the use of appropriate solar shading reduces the use of energy (and therefore cuts CO2 emissions) and also saves money.
See for two examples:
-Shade Specifier in the U.K. on http://www.bbsa.org.uk/ShadeProject.aspx and
-Textinergie in France on http://www.textinergie.org.
Other sophisticated packages to evaluate the energy efficiency of solar shading on http://www.parasol.se/.
