Commercial HVAC Systems: Factors in Selecting the Right System

The type of HVAC system a building needs could depend on several factors. To find out what they are, the building owner should have a commercial HVAC company perform a heating and cooling analysis. Only then can HVAC systems that meet the building’s climate control needs be identified. After an HVAC service performs a heating and cooling analysis, it will determine the best system for the building by considering the following factors, among others:


Climate can have a significant influence on the type of HVAC systems buildings require. In general, the greater a climate’s temperature extremes, the more climate control buildings that are located there require. Some exceptions are facilities that are located partially underground and experience natural cooling, and facilities that remain warm or cool due to processes that occur inside.

Geographical Positioning

In some climates, a building’s geographical positioning can supply it with unique climate control capabilities. Often, this positioning is the result of design intent. For example, passive solar design allows a building to take advantage of its local climate through window positioning, roof positioning, and other strategies. Whether a building receives a heating or cooling benefit from its geographical position intentionally or accidentally, the HVAC system it receives should be implemented with the effect in mind.

Building Architecture and Condition

A building’s architecture and condition can determine the type of HVAC equipment it can receive. For example, some buildings require ductless air conditioning systems that preserve interior design, while others require old utility rooms to be redesigned to accommodate new equipment. In most cases, a building’s architecture and condition are not limiting to commercial HVAC systems.

Internal Temperature Sources

As mentioned above, some buildings have internal processes that create noticeable temperature effects. For example, a building that contained a steel foundry would have a higher temperature in its work zones than most other buildings. Such effects should be factored into which HVAC system a building receives.

Building Envelope

A building’s envelope is positioned in the space between its interior and exterior walls. Depending on its design, a building envelope could have a dramatic insulating effect that holds in heat in the winter and coolness in the summer. When it possesses a high insulating capacity, a building’s envelope can be a major factor in what type of heating and cooling system it needs.

Special Needs

Also important in choosing an HVAC system are special air quality needs that a building might have. These needs could include such things as filtering out airborne chemicals, special temperature maintenance, and special humidity maintenance.

Does Your Building Need a New HVAC System?
