What Are HVAC Systems

What are HVAC Systems and What Role Does the Structural Engineer Play?

construction siteWhen a Structural Engineer designs a new structure, whether it is a home in the private sector, company building, or large industrial plant he or she needs to develop and construct a particular ventilation system. Heating, air conditioning, ventilation, and refrigeration are all correlated together, providing for the structure, temperature comfort and a quality air supply. It is the responsibility of the Structural Engineer to develop a reasonable rate for this installation, and maintenance. The HVAC system allows for the delivery of air quality control and air distribution. HVAC systems allow for comfort, ventilation of indoor air infiltration, and air pressure maintenance.

HVAC offers to the public in this high-tech world a way to heat, vent, and condition the air for indoor use. The HVAC system is a branch of mechanical engineering based on the technologies of thermodynamics, heat transfer, and fluid mechanics.

An HVAC system is essential in the design of any structure or closed area where there are people. These areas include ventilation for private and military sea vessels, aquariums, skyscrapers, office buildings, large and small businesses, and more. It is the HVAC system in a structure that keeps people safe and healthy by using fresh air from outdoors.

HVAC systems remove any number of substances such as but not limited to smoke, dust, airborne bacteria, carbon dioxide, odors, excessive moisture, stagnant air, and mold and mildew spores. HVAC systems involve temperature control and oxygen replenishment. The result of this system leaves buildings with quality breathing air.


The Structural Engineer and Mechanical Engineer work together in the construction of structures to develop the most cost-effective HVAC system available. HVAC systems involve heating, cooling, humidifying, dehumidifying, cleaning of air, and the ventilating of air. It is the responsibility of this professional to construct the most efficient system for the allowed space in the structure.

If the professional has been correct in his or her calculations, the HVAC system installed will show effectiveness in achieving comfort in temperature, humidity control, and quality air filtration.

HVAC technologies continue to expand and improve in currently offered HVAC systems that add quality of life to the public domain. It is essential that the Structural Engineer professional continues to play a vital role in delivering and preserving indoor air and works with Mechanical Engineers in the field of HVAC system.
