STORY OF PROJECT
The Oaks Zero Energy Community at Rose Villa is the first community in the Portland senior housing market to achieve Zero Energy Certification; demonstrating that it produces all or more of its own energy needs through on-site renewable energy. The Oaks includes 12 craftsman-style homes built to meet Passive House principles that support health and energy efficiency. Residents will likely have low-to-no energy costs while enjoying comfortable, quiet homes with fresh, filtered air. Each home also features durable, high-quality finishes, modern, energy-efficient appliances and perks such as bicycle storage.
OCCUPANCY ENGAGEMENT STRATEGY
The occupancy engagement strategy consists of unit-level metering and periodic review with the residents.
