Summer shading performance of awnings at the CCHT : NH18-22/112-104E-PDF

A project to directly measure reduced air conditioner energy due to awnings was conducted at the Canadian Centre for Housing Technology (CCHT). Significant passive heating can be provided by solar energy entering the windows of a house. Management of these solar gains in all seasons can minimize energy use for space heating and cooling. In the heating season, maximizing solar gains minimizes energy use, but can also cause occasional overheating, especially in very energy-efficient houses with large areas of south- or west-facing windows. In the cooling season, solar gains should be minimized to reduce cooling loads and to avoid overheating.
