The Autumn 2022 issue of District Energy magazine highlights the central plant expertise of Precis Principal Josh Capparella, PE, LEED AP BD+C, and Mechanical Engineering Manager Shane Helm, PE.
In the article, “Enlisting the Pareto Principle,” they discuss chilled water system optimization. The article applies the Pareto Principle (also known as the 80/20 rule) to chilled water plant operations to optimize savings against up-front capital costs. Capparella and Helm provide strategies to improve operational and energy efficiency while avoiding an all-or-nothing approach.
District Energy magazine is published by the International District Energy Association, an organization that fosters the success of members in providing reliable, economical, efficient, and environmentally sound district heating, district cooling, and combined heat and power.
