Most of these healthy features directly relate to energy efficiency: amenities like opportunities for VENTILATION - Meet or exceed outdoor air ventilation rate guidelines to control exercise and access to nature.

The Council on 2 designed for energy efficiency also improve thermal comfort with added insulation and ventilation, which can result in better indoor air quality and moisture management. Local government programs can offer incentives to commercial building owners for constructing green build- ings that primarily improve energy efficiency but also improve health. For example, the City of Pittsburgh has a Sustainable Development Bonuses program that offers building owners the option to increase floor area and building height up to 20% Photo credit: Pacific Northwest National Laboratory over the zoning limit if the building is LEED certified. with ASHRAE and other productivity; it has been implemented organizations to provide prescriptive in more than 1,000 buildings across Business Case design strategies for both energy and the world.
