A whopping 95 percent of the country’s existing commercial buildings are smaller than 50,000 square feet and account for 44 percent of energy usage in all commercial buildings. But, did you know that the majority of green retrofits are performed on the other five percent of buildings?
Taking into account their greater homogeneity and economies of scale, owners of large buildings have an easier time commanding the capital and the technical support needed for energy retrofits. In contrast, owners of smaller buildings -- which typically have unique and varied characteristics and requirements -- often are not adequately served by financial or technical resources, or by regulatory frameworks designed with larger and newer buildings in mind. The National Trust’s Preservation Green Lab has been committed to advancing the reuse and retrofit of older, smaller buildings though its Older Building Performance Program.
Like the Preservation Green Lab, Living City Block is also committed to bringing new investment to smaller, older buildings. In her article, Greening an Entire Block Instead of Just One Building, The Atlantic Cities writer Emily Badger explains the concept:
"Living City Block's basic concept is simple. Small buildings rarely have the resources to do a serious retrofit. For most of them, the idea is cost-prohibitive. But what if you combined a small building with 10 more like it?"
Could building owners achieve the kind of economies of scale comparable to larger buildings by working collaboratively rather than separately? We're about to find out. Living City Block is currently testing this concept on two blocks in Denver comprised of 17 buildings, 16 of which are historic. The project is expected to see a 50 percent reduction in the buildings' combined energy use.
