Revision history [back]

As an energy modeler, I routinely have to build models of existing historic buildings. Almost always there is no information available on detailed building envelope construction other than that the walls are made of brick or the floors are timber construction. I can only guess what thermal properties the exterior envelopes of such existing buildings might have. Does anyone know a good resource that would list the most common wall/roof/floor/windows construction assemblies and their thermal properties by decade (1890s, 1920s, etc.) ?
