Architects often do not place enough emphasis on HVAC (Heating, Ventilation and Air Conditioning) systems at designing stage; more often than not, it is just an afterthought! It is crucial to understand the importance of creating sustainable, self-sufficient structures which is incidentally possible only through an integrated approach. Good HVAC systems are not only a crucial element in a building, they also offers high returns on investments when selected wisely. Since the HVAC equipment are expensive and have a long life, it is difficult to replace an under-performing system without adding a significant amount to the operations cost.
As we know that the majority of the energy consumption in any facility is on HVAC, surprisingly it is close to 50% to 55% on the commercial developments. With lots of development on energy conservation, renewable energy is on the cards nowadays and many companies follow it as a mandate and spend huge on this regard. Keeping this as a major impact in all respects, the sustainability design, energy-efficient design is being practiced now. Even then the utility bills are high due to lots of factors pertaining to operation and maintenance of the system. This can be definitely lowered down by using the intelligent building management system installed for the equipments, proper routine maintenance of all the equipments, seasonal programming of the system operations, maintaining the logs and consistently studying the trends and operating the plant accordingly, using the sensors and automating the equipments etc.
