1.1 Site Form and Massing

Reduce solar exposures at west and east facing elevations, minimizing solar heat gain from low sun altitudes. Cold climates: Consider passive solar design principles, depending on program use.

Climate-specific design: Consider annual air temperature, wind data, etc.
Site-specific design: Access to public transportation, views into the site/ from the site, noise attenuation, etc. Use ‘The Weather Tool’ component of Autodesk’s Ecotect Analysis software (

Create and analyze sun path diagram specific to latitude and longitude. Conduct analysis of site specific characteristics, i.e. water body, wind exposures, urban axis. Use design simulation software. Maximize extent of south and north facing building elevations, minimizing extent of east and west facing building elevations (for non-residential). Analyze prevailing wind directions and take advantage of natural cooling, conditions permitting.

Strategic investment. Lower operational energy cost. Higher resale value due to energy efficient layout and lower utility cost.

Superior operational energy efficiency, performance and cost effectiveness due to selective building orientation with respect to sun path and wind (i.e. passive heating, cooling and natural ventilation). Maximum user comfort, based on glare mitigation.

Consider cultural requirements (i.e. no north-facing residential units in South-Korea). Avoid single-family residential clusters and sub-divisions, due to inefficiencies in envelope to volume ratio, roads, services and utility requirements.
