Day Lighting Design in Building

Introduction

This is an interactive programme for computing daylight available at a point in horizontal or vertical plane for Indian standard design sky condition from basic mathematical equations. The inputs are room dimensions, window descriptions, external obstructions descriptions, reflectivity of room surfaces, etc. The outputs are sky components, ERC and IRC and hence the design daylight factor. Rooms and window must be of regular shapes.

Salient features

Based on basic analytical equations, this software can analyze the daylight available in different points of a room in an accurate way and is more accurate than the normal tables, which are used for similar computation.

Prospective Users

Any architectural organization, CPWD, HUDCO etc.

Keywords
