Passive Design
Passive design refers to a design approach that uses natural elements, often sunlight, to heat, cool, or light a building. Passive solar or passive cooling designs take advantage of the sun’s energy to maximize heating or cooling based on a building’s sun exposure. Systems that employ passive design require very little maintenance and reduce a building’s energy consumption by minimizing or eliminating mechanical systems used to regulate indoor temperature and lighting.

The passive design approach can include the structure of the building itself, including building orientation, window placement, skylight installation, insulation and building materials, or specific elements of a building, such as windows and window shades. For example, installing operable windows, or windows that can be manually opened and closed, allows residents to control the amount of air entering a space, and placing operable windows directly across from each other can direct breezes into a building, creating natural ventilation.
