Case Study: A COA’s Impact on a Project
Before: The owner of a Colonial house from the 1920s wanted to replace the wooden historic windows with vinyl.
Without COA: The outcome is that the proposal was rejected because it would not have preserved the building’s historic character.
With COA: The proposal was approved after they modified it to use wood-clad replicas of the original design windows. The home also passed the energy efficiency tests, so it was able to maintain its charm and energy efficiency.
