Brief description of the retrofit project
Preserving an old train station (built in the early 1900's, I think. I could find out the exact year.) Replacing the 1980's addition on the back of the station. Energy retrofit to the whole thing. Here are a couple of social media posts about it: https://www.instagram.com/p/Cuy8fKMI7UI/?utm_source=ig_web_copy_link&igshid=MzRlODBiNWFlZA==
