Abstract

It is estimated that buildings use more than 40% of the total energy generated for heating, cooling and lighting, among other uses. Many people still depend on artificial light during the day. This may be due to inefficient design and construction using climate inappropriate materials, combined with poor understanding of thermal comfort, passive building principles and energy conscious behaviour. All these factors contribute to tremendous energy wastage.

Fossil fuels, which are the main sources of energy generation, are limited, diminishing and unsustainable in the long term. Due to these limitations, it is necessary to reduce the electricity load in buildings. By planning for daylighting right from the on set of the design process, significant energy savings can be achieved.
