By way of context, most glazing is "static." That means it has certain performance properties that remain the same, including visible light transmittance (Tvis), solar heat gain coefficient (SHGC), and U-factor.
Our April EBN feature article--"Passive House Arrives in North America: Could it Revolutionize the Way We Build?"--went online today. This was a fun article to research and write, because it put me in touch with my low-energy building roots.
The last several weeks I've written about common myths of green building: that it has to cost more to build green, that green building is mostly about materials, that green products don't work as well as conventional products, and that
