4 HVAC Strategies for Large Commercial Buildings in 2023

4 HVAC Strategies for Large Commercial Buildings in 2023 

In big commercial buildings, HVAC offers a great chance to save energy and be more eco in 2023. With new government rules and ways to measure efficiency, companies have good reasons to make their HVAC systems more energy-efficient. This article looks at the most effective ways for large commercial buildings. This could be used to save money and energy this year with their HVAC systems.

The Imperative of Energy Efficiency in HVAC Systems

The energy consumed by HVAC systems accounts for a staggering 44% of total energy usage. By optimizing the efficiency of HVAC systems, businesses can realize tremendous cost savings. For instance, enhancing HVAC efficiency by as little as 10% can lower energy bills by 8%. 

Besides saving money, HVAC systems help businesses show they care about the environment. Because sustainability is a big part of being a responsible company. These kinds of upgrades give commercials a great chance to lower their impact. This helps to protect the environment and reduce their carbon footprint.

Understanding HVAC Efficiency Metrics: SEER and EER Ratings

The SEER is a metric used to measure the efficiency of cooling systems. It’s calculated by dividing the cooling output during a typical cooling season. A higher SEER rating indicates a more efficient cooling system. The higher the SEER, the more energy-efficient the AC unit is. The Energy Efficiency Ratio (EER) shows how well air conditioning works when it’s hot outside, like at 95°F.

When evaluating contractors, ask about their experience with commercial HVAC installation services for buildings to yours. Have they handled large-scale upgrades and retrofits before? Getting the right contractor expertise ensures your HVAC upgrade delivers ROI and performance.

EER provides an instantaneous snapshot of performance. In 2023, the SEER metric evolved into SEER2 and the HSPF into HSPF2 due to major changes in the testing method. The new testing procedures offer an authentic view of real-world operational efficiency.

HVAC Standards in 2023: From Small Businesses to Large Commercial Buildings

Following the Department of Energy’s efforts to lower the country’s energy use. The more stringent federal rules for HVAC systems started in January 2023. For small business applications, the least SEER rose from 14 to 15. 

The standards are even more rigorous for large commercial buildings. With required SEER ratings ranging from 18 to the mid-20s depending on the unit capacity. To meet the latest federal requirements and prepare for strict national efficiency standards. It is crucial that any installations during 2023 use units that meet these standards. Investing in high equipment not only ensures at present but also in the future.

Exploring Energy-Efficient HVAC Systems for Commercial Buildings

1. Variable Refrigerant Flow (VRF) Systems

VRF systems are good at controlling the temperature. They prevent energy wastage by adjusting the amount of cooling or heating. They deliver to various areas based on their specific requirements. With SEER ratings reaching the mid-20s, VRF systems are optimal for large facilities.

2. Heat Pump Systems

Heat pumps can provide both heating and cooling through the use of a refrigeration cycle. The most efficient models are over 4 times as efficient as the older ones with SEER ratings of 19 and beyond. This dual-purpose ability makes heat pumps perfect for large commercial spaces.

3. Geothermal HVAC Systems

Geothermal uses the temperatures underneath the earth’s surface to heat and cool spaces. Although geothermal systems involve high upfront costs, they offer efficiency and long-term savings.

4. Smart HVAC Systems

Smart HVAC systems integrate with IoT technology in real-time. This could be used for performance monitoring, predictive maintenance, and automation based on occupancy patterns. Combining smart tech with high-efficiency equipment maximizes cost and energy savings.
