An HVAC design engineer is responsible for designing, maintaining, and upgrading heating, ventilation, and air conditioning systems in buildings. They ensure that indoor temperature and air quality can be regulated in response to outdoor climate, and may also work on identifying areas of heat loss and positioning duct work and ventilation to maximize heat output. A bachelor’s degree and professional certification are typically required for this field.
An HVAC design engineer works with the systems that control temperature and air control in buildings. HVAC is the common term for heating, ventilation and air conditioning. Some engineers are involved in integrating HVAC components as a structure is being designed and built. Other HVAC professionals work on maintaining, upgrading, and cleaning existing mechanical systems. Ensuring that the indoor temperature and air quality of a home or commercial building can be safely and accurately regulated in response to the outdoor climate is often the job of an HVAC design engineer.
Heating a structure involves using materials and infrastructure to circulate the flow of hot air. Cold air and drafts must be minimized and ventilation to distribute heat flow drafts must be designed to reach areas of the building where people work and live. Weather insulation can save energy costs and increase the ability to retain heat. An HVAC design engineer may be responsible for identifying areas of heat loss and positioning duct work and ventilation to maximize and direct the heat source output.
Ventilating homes and commercial buildings can be considered a matter of air circulation for the comfort of the people using them. HVAC design engineers, however, are generally trained to understand the importance of designing and monitoring ventilation for the good of the structure itself. Foundation strength and overall structural integrity depend on well-placed ventilation systems. Those who live and work in buildings also rely on HVAC engineering to ensure air quality. Building codes often outline measures necessary to maintain a consistent flow of fresh or filtered air in and out of structures.
Air conditioning is a necessary component to replace hot indoor air with generated cold air flows. As with heating control, HVAC design engineers may be responsible for ensuring that AC temperature controls work well with the general ventilation system to respond to conditions outside the building. Understanding and applying formulas for cooling based on air volume and cubic size is often a part of HVAC training.
Mechanical engineering principles encompass much of what an HVAC design engineer will need to learn, and a bachelor’s degree is usually required. Basic engineering and architectural principles, familiarity with the specific building codes of the country where the work will be carried out, and specific training in working with the HVAC units themselves can form part of the course. Working as an HVAC engineer can include co-designing with architects at a planning level as well as fine-tuning at a mechanical level. Professional certification is typically required for HVAC work.
