Commercial buildings need to be comfortable and functional, which requires an effective HVAC system. The United States Department of Energy estimates that nearly half of a commercial building’s energy consumption comes from heating, cooling and ventilation, highlighting the importance of efficient design and implementation. By considering these aspects of a commercial HVAC system, technicians can identify ways to help property owners increase energy savings.
System Design
Peak efficiency presumes that the system itself has an efficient design. Many commercial buildings, especially those built decades ago, do not feature efficiency in the structure design or use. As a result, poorly designed systems may hinder efficiency efforts, when HVAC technicians can only upgrade the equipment. Instead, evaluating the design can yield new opportunities for increasing efficiency, such as changing the placement of windows or increasing insulation to minimize heat transfer. Even reconsidering the type of HVAC system — by switching from a split system or packaged system to an efficient alternative like geothermal — could significantly decrease operating expenses and energy use.
Component Upgrades
When planning upgrades for the commercial space, efficiency should be a key component of the decision. Maximum efficiency for the equipment is a lofty goal and may be necessary depending on the comfort needs of the space or the sustainability goals of the property owner. Upgrading a system can happen in pieces, but technicians should weigh the advantages of a full replacement against the lower cost of upgrading equipment over time. In some cases, the equipment will not provide the same level of efficiency if it must interact with older, inefficient units or devices. Upgrades that affect sizing or output may require other system updates, such as ductwork repair, to maximize efficiency.
Proper Sizing and Installation
The ideal equipment depends on the commercial building’s size, layout and other factors. Correct sizing and professional installation are key to maintaining peak output and efficiency over time. Units that are too small for the load may take on too much stress, leading to repairs and premature replacement. Systems that are too large may provide cooling too quickly to ensure ideal humidity control. HVAC technicians should perform a load calculation before recommending specific units and schedule professional installation as part of the upgrade. Accurate installation can preserve efficiency and output through the equipment’s lifespan.
Smart Controls
Better energy consumption comes from the equipment itself, its installation and the use of the system. Many commercial property owners lose out on energy savings because they lack the tools to minimize their energy consumption, or they worry that cutting back on usage will compromise comfort. Technicians can assist by explaining how efficient controls can work with the system to improve efficiency and decrease waste. Implementing smart controls with effective settings can help property owners to reach their targets for comfort and energy efficiency.
Regular Maintenance
Even the best design and equipment installation requires routine care to keep it in ideal working order. Property owners should arrange for annual heating and cooling services — in the fall for heating and the spring for cooling. Regular maintenance can provide the following:
- Professional test of the system
- Inspection of components and systems
- Cleaning and lubrication of moving parts
HVAC systems often lose efficiency over time, due to gradual wear and tear on the equipment. Routine upkeep can minimize efficiency losses by ensuring proper operation of the equipment each year, with early notice of problems to fix.
Improving HVAC efficiency for commercial buildings offers many benefits. It can lower operating costs, minimize breakdowns, remove stress from the local power grid and improve the environment. By implementing this advice, HVAC technicians can assist their commercial clients in maximizing efficiency.
