The Significance of Light and Wind Movement in the Building Construction

Natural ventilation can be described as a method of providing and eliminating air through an indoor space via natural means (without using a fan or other mechanical device).

It provides ventilation and space cooling using outdoor air flow due to pressure variations among the building and its surrounding. Wind ventilation is the easiest, least expensive, the most common form of passive cooling and ventilationGood wind ventilation is determined by using high thermal comfort and adequate fresh air for the ventilated spaces while having little or no power use for active HVAC cooling and ventilation.

Daylight is the controlled admission of natural light and direct sunlight and diffuse skylight—into a building to reduce electric lighting and saving energy. The lighting provided just by daylight alone, is a capability to reduce electric lighting power. These are very important info’s which needs to be considered when the building is under construction.
