Buildings are no longer only a shelter where people can stay. Instead they are becoming a provider of all modern facilities, such as heating, cooling, maintaining air-quality, telecommunication, security, fire-protection and access control. In these modern buildings, a considerable proportion of energy is used to maintain air temperature and humidity. Considering the building as a slow process, energy saving lies with the controlling of air-temperature and humidity in a proactive manner.

Towards this effort, Abul Azad, Ph.D., has been involved with the development of effective computer models. These models can be used to predict the indoor temperature and humidity and can take proactive measures to maintain to a set level with minimum energy use. He is also involved with the implementation, monitoring, and control of building energy consumption over the Internet.
