Commercial HVAC System Design
The heating and cooling load for two businesses housed in identical buildings can differ dramatically depending on occupancy rates and generated heat. Retail environments and heavy equipment can be especially challenging, and they add substantial complexity to the design equation. In many instances, the HVAC system should include an economizer, a make-up air unit, and advanced controls.
At McWilliams & Son Heating & Air Conditioning, we rely on sophisticated ACCA Manual J formulas to determine the building’s precise requirements for conditioned air in all seasons. Equipment for commercial applications is selected based on the following criteria:
- Building Size
- Local weather data including humidity and temperature history
- Ceiling height
- Perimeter envelope tightness and integrity
- Insulation R-values
- Duct leakage
- K-values for windows and doors
- Machine generated loads
- Occupant generated loads
- Process generated loads
Energy Efficiency Upgrades
Rising energy costs and environmental regulations have led to the development of technologies that save energy and reduce harmful emissions. Installing energy-saving equipment can improve HVAC system performance by up to 50 percent. Here are a few of the upgrades we recommend.
- Energy recovery ventilation
- Programmable controls
- Economizer technology
