Optimized Operation of Indoor Public Pools


Indoor public pools represent an opportunity for significant energy savings in Minnesota. Optimized operation of these facilities requires careful balancing between pool temperature and the combination of air temperature and humidity. Modest changes in any one of these can throw off the balance and have large energy and comfort impacts. Operational issues with HVAC equipment can also cause excessive energy use that goes unnoticed. Based on our market research conducted as part of this project, we estimate that there are approximately 600 indoor public pools in Minnesota larger than 2,000 square feet, about 1,500 smaller indoor public pools, and about 900 spas. We found that all of these had a combination of high energy use, complexity and prevalence, making indoor public pools a ripe opportunity for energy savings.

This project was undertaken to develop specialized guides designed to provide energy savings through quality maintenance and operation of indoor public pool facilities, and to investigate their energy impact. The focus is on making the best use of existing HVAC equipment, as well as low to moderate cost upgrades (e.g. control optimization). One guide is designed for recommissioning providers working with CIP programs to help them maximize the savings achieved while minimizing the cost of the recommissioning services. The second guide is designed for use by technicians that deal with a facility on a regular, ongoing basis as well as serving as a complement to the recommissioning guide.
