ENERGY EFFICIENCY, HVAC, THERMAL COMFORT AND PASSIVE DESIGN

 

The central philosophy behind green building is the judicious use of resources in a manner that provides for man’s needs today without jeopardizing the ability of the future generation to fulfill their own energy needs.

The illustration above shows the authors’ conceptualization of how energy consumption is related to the use of HVAC equipment, which emanates from the need to maintain a comfortable indoor environment for the occupants in terms of indoor air quality and thermal comfort. The arrows indicate the two way relationship between the sections implying that any change in either of the sections bears significance on the others.  The authors’ argue that for energy consumption to reduce, passive design strategies must be adjusted to provide alternative sources of natural ventilation and thermal comfort. Such design strategies may include but not limited to design issues affecting building height, form, orientation, etcetra.

If we are going to continue building tall, we must figure out how to keep the energy consumption of such buildings within environmentally and economically sustainable limits.
