13 pages, Peer-to-peer learning is gaining increasing attention in nonformal community-based environmental education. This article evaluates a novel modification of a concept for peer-to-peer learning about residential energy solutions (Open Homes). We organized collective “Energy Walks” visiting several homes with novel energy solutions and engaging people beyond those with a serious renovation project. We evaluated the intervention in terms of individual, network-centric, and institutional learning outcomes. Learning outcomes were observed on all these levels. We argue that this form of peer-to-peer learning builds capacity for sustainable action in the community by supporting discussion and reflection, rather than merely social learning as modeling.
