The increased quality of life requires indoor illumination environment to have illumination with higher intensity. The increase in indoor illumination goes hand in hand with increase in indoor heat load. Of late, the internal heat in the cooling load has been growing gradually and the proportion of the lighting load has been bigger in the cooling load. The objective of the experiment here is to estimate the proper exhaust air flow displacement to remove heat from different types of lighting equipment. The heat causing the cooling load in lighting equipment is the ratio of heat per watt and the ratio of space for heat. Experimental measurements of the constant temperature and humidity in chambers that exhaust air flow by changing the exhaust calorific value was measured. Using the Airflow exhaust heat from lighting fixture of this study should help to reduce House cooling load.
