Shading II

logo

A plugin for SketchUp that enables analyzing any given design with regards to solar rights or shading requirements. It allows the examination of the mutual shading between buildings and any other objects. It can perform an accurate evaluation of the design of any external or internal windows' shading devices as well. The analysis can be carried out visually and quantitatively The plugin allows the designer to plan efficiently the various functions of spaces among buildings in an urban environment, as well as determining the location of the passive and active solar collectors. The plugin allows to calculate the (Geometrical) Shading/Insolated Coefficient of any surface selected from the 3D model. Screen Shots

Input

The SketchUp geographical location and 3D model are the only required input data.

Output

Output outcome in two ways: visual (sun view) and CSV (Excel compatible) calculation results for the user determined period of analysis.

Computer Platform

Windows

Programming Language

Strengths

Calculates the shading coefficient (percentage of sun exposure) of any given surface (s).

Weaknesses

To analyze SketchUp components' surfaces you have to explode it.
