What are HVAC systems?
Heating, ventilation and air conditioning systems, aka mechanical systems, maintain optimal temperature, relative humidity and air movement to achieve occupant comfort. HVAC systems also may be designed to meet energy performance goals, prescriptive requirements or other needs as identified by the building owner and occupant. HVAC systems often are managed by building automation systems as part of a larger goal to control the building’s engineered systems.
Many consulting engineers base their designs on performance, thus the focus on performance-based design in many specifications for HVAC system design.
The integration of high-performance HVAC design strategies can do as much to make systems energy-efficient as specifying high energy efficiency ratings.
Boiler codes and design standards provide the basic guidelines for boiler application, design, construction, and operations.
