A Study on the Coexistence of Monument Protection and Energy in Southern Germany's the Old Town—Focusing on Installation Requirements for Rooftop PV

The purpose of this study is to gain knowledge about the coexistence of monument protection and energy in southern Germany's Old Town through resident intentions, laws, and permit decision criteria. First, there is a movement to allow rooftop PV on buildings in the Old Town. Next, there are two requirements for rooftop PV installation under the Old Town Protection Law: (1) building evaluation of monument protection and impact on surrounding buildings, etc. and (2) visibility from public spaces. It has become clear that the expansion of the interpretation of “public space” as a viewpoint is protecting historic buildings.
