As shadows and reflections are an important aspect of building design, shadow analysis enables an understanding of the extent to which shadows from other local structures affect the specific property that is being designed. This helps to take the right decisions regarding placement of parking lots, solar panels, windows etc. Viewing shadows in this manner allows the designers to focus on specific objects that can hinder or support some of the functional aspects of the design, or quickly see the location of sun-patches as they travel across the floor and up a wall.
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
Arial image of building along with adjacent structures (and some data)
Outputs
The typical outputs generated from the analysis are graphical and tabular representations of the times during which the object of analysis will be in shadows.
Tools & Approach
Autodesk Ecotect, version 5.6
Relationship to LEED® Credits
None directly. It could influence the LEED® Category of Energy and Atmosphere- Renewable energy if photovoltaic systems are in the path of the shadows
