HVAC system design
1 AIA CES approved LU available for attendees upon successful completion of an exam
Depending on the building and its geographic location, there are several techniques for specifying HVAC systems in nonresidential buildings. A new or existing building each has its own requirements, and mechanical engineers must understand the client’s needs, the codes and standards, humidification/dehumidification needs, energy efficiency goals and the specific building requirements to successfully design a system.
Based on the most recent Consulting-Specifying Engineer research, the top three HVAC products/systems most specified are:
- Air handlers.
- Fans, air movement.
- Rooftop units.
There are many factors to consider when choosing and designing HVAC systems for buildings. Those decisions ultimately influence how energy-efficient the building is. The major factors to optimize for energy efficiency are ventilation, zone control, heat recovery and operations.
- Learn about ASHRAE, International Mechanical Code and other guidelines that drive HVAC system design and specifications.
- Understand HVAC design strategies, and the various products and systems available. Know the basics of how building automation systems and controls are integrated into this design.
- Consider energy-efficiency goals, and what HVAC products or systems can help achieve them.
- Review commercial buildings example design strategies.
