Green Building

DEQ’s Green Building Program focuses on reducing the environmental impacts of building material consumption over the lifecycle of residential homes. This page summarizes DEQ’s current and recent work in this field.

Accessory Dwelling Unit resources

Additional actions on space-efficient housing

DEQ research shows that reducing house size is the most effective way to reduce both material and energy-related impacts of residential homes. The work below represents DEQ’s efforts toward having the residential construction field recognize home size reduction as an effective green building strategy. 

  • Energy Trust of Oregon
    This non-profit organization provides incentives for energy-efficient new construction practices as well as retrofits on existing homes. It recently recognized the energy saving benefits of detached accessory dwelling units by allowing full-scale “new home” incentives to be applied to units. 

  • GreenPoint Rated
     This California based nonprofit administers a labeling and certification program for new and existing homes. Its program already accounts for home size as a function of operational energy consumption. The group is now using DEQ research to inform the material-related impacts of different size homes based on embodied energy and greenhouse gas emissions from material production.
