To set energy performance indicators (EPIs)on HVAC usage and implement HVLS fans as part of an ISO 50001 energy management system, follow these steps:

1. Conduct an energy review

Begin by conducting an energy review to identify the current energy consumption of your HVAC system and any opportunities for energy savings. The review involves collecting data on your HVAC system's energy usage. Walk-throughs of your facility is an easy method to identify any inefficiencies or areas for improvement.

2. Set energy performance indicators

Based on the results of your energy review, set specific, measurable, achievable, relevant, and time-bound EPIs. They mustrelate to your HVAC system and your overall energy consumption. These EPIs could include reducing your HVAC energy consumption by a certain percentage over a set period of time. Simply increasing the efficiency of your HVAC system by a certain amount works as well.

3. Implement HVLS fans

To reduce energy usage and improve the efficiency of your HVAC system, consider implementing HVLS (high-volume low-speed) fans. These fans are designed to circulate large volumes of air at low speeds, which can help to distribute heat and cool air throughout a building evenly. Uneven temperatures cause the HVAC system to run longer for worse results. You can reduce the energy needed to maintain a comfortable indoor temperature by using HVLS fans in conjunction with your HVAC system.

4. Monitor and review your energy performance

Regularly monitor and review your EPIs to track your progress towards meeting your energy efficiency goals. It involves monitoring your energy consumption, comparing actual usage against your EPIs, and identifying any issues or challenges hindering your progress.

Overall, setting EPIs on your HVAC usage and implementing HVLS fans can help you reduce your energy consumption.  It meets the requirements of ISO 50001 by improving your energy efficiency and reducing your greenhouse gas emissions. By regularly monitoring and reviewing your progress, you identify areas for improvement.  Identifying these areas is the first step in   improving your energy management.
