HEATING VENTILATION & AIR CONDITIONING Design is a sub discipline of mechanical engineering that deals with the art of heating- air conditioning and ventilation systems of the building to achieve comfort.. The scientific design of HVAC
system is critical to achieve an efficient and effective environmental control system within a liveable. The successful integration of building constraints- air movement conditions and equipment selection can positively impact system overall performance and
decrease utility expenses and capital expenditures.To achieve the optimal design- one should need good analytical skills and up-to-date technical knowledge in the subject.
Comfort is a state of mind and is our profession.

ABOUT US
‘Alpha Building Services’ is a multi-level business venture formed by few experienced engineers from different building service sectors across the world. Our services include academia on the art of MEP design intended to mold skilled MEP design engineers and draughtsman out of conventional engineering degree/ diploma graduates who are keen about building services industry, corporate training and consultation in MEP and firefighting services.
India, as a developing country had not enforced the building codes and standards as such for the construction and alteration of the buildings successfully though is self-sustained and rich in its own design codes and standards. In the wake of 21st century, different governments has brought drastic changes in the rules and regulations of the building industry which all builders, designers, consultants and engineers have to follow for the safety and efficiency of building and occupants.
In this scenario, the biggest challenge what the building industry faces is the lack of experienced engineers, MEP designers and draftsmen. It was in this context Alpha Building Services was established with the pledge to provide high quality engineers and services to the building services industry. ...
