Passive Design

Passive design refers to a design approach that uses natural elements, such as sunlight and wind, 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 and the local prevailing wind condition. 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.

In ZCB, the various passive design measures lead to 20% energy saving compared to a similar building of the current standard design.
