...on my next project.  I met with Ertex Solar when I was in Freiburg in June about their building integrated photovoltaic product.  Glass--glass modules with architectural grade solar cells from Sunways--they call it PV Glass.  The interstitial LED's were a little over the top, but the modules were beautiful. 

Only problem is that the modules are not UL 1703 listed, and Ertex is not planning to do so because of the custom nature of their fabrications.  We would need a UL Field Evaluation if we were using these modules to generate power.

PV is the sizzle that sells green architecture.  I am thinking about a new way of signifying how a building wants to meet its triple bottom line responsibilities.  Visual cues and feedback through the property's information system is a key element of showing how we meet this responsibility.
