Description

Good design for building requires sufficient daylight for tasks performed within a space. This is achieved by providing enough means to let in diffused light from the sky, but keep out direct light from the sun to prevent heat gain and glare. Daylight analysis is the process by which the amount of diffused sunlight that enters into the interior of a building is estimated. This analysis does not take into account the direct sunlight entering into the building, but it uses the luminance of the standard overcast sky from weather files as the measure of the exterior diffused sunlight. It helps us assess the impact of the exterior surfaces on the entry of this light into the interior floor space of the building.

Inputs

The typical inputs required to undertake the analysis are:

Site Plan
Floor Plan
Roof Plan
Elevations
Fenestration Schedule and Properties
Weather data
Building Model
Building Material Properties

Outputs

The typical outputs generated from the analysis are graphical and tabular representations of the amount of illumination received in the interior at 30" above floor level.

Tools & Approach

Autodesk Ecotect, version 5.6
BIM models created in Revit Architecture can be used as to acquire geometric inputs

Relationship to LEED^®Credits

If opting for LEED^® certification, then this analysis helps in designing the building as per the LEED^® Daylighting requirements. The LEED^® credit category that is influenced is Indoor Environmental Quality- Daylight and Views.

Consulting Support

If specific parameters are of interest to the design team, various iterations of design can be provided with an output of the specified parameter in graphic or table form to support design team decisions.
