ABSTRACT
In this new era, energy conservation is the main concern. Thermal comfort is the condition of mind that expresses satisfaction with the thermal environment. Unnecessary air condition of heating for thermal comfort is one of the reasons for excessive consumption of energy. Researchers have come up with ways to measure the comfort level in order to avoid over consumption of energy used to heat or cool the buildings. In 1970 Fanger laid out the foundations of this measure using his PMV-PPD model; which is based on heat balance equation. However this model considers human body as a passive object and does not give an accurate result when used in tropical countries and other countries like Spain. Due to the wrong predictions of static heat balance model, a more dynamic approach to thermal comfort is needed. This is called as an adaptive approach which can change the Fanger’s model from static to dynamic. This research project aims at checking the sensitivity of Fanger’s comfort equation to the variables in the equation and proposes a method to add adaptive theories into the equation.
