"This session will provide a comprehensive technical overview of modern pressure-boosting system design, integrating hydraulic fundamentals with advanced efficiency and control strategies. It will begin with system design basics, including demand profiling, NPSH considerations, pump selection methodology, and an evaluation of different boosting configurations. The impact of chronic pump oversizing will be examined through energy modeling and life-cycle cost analysis, illustrating the operational penalties associated with inaccurate system design assumptions.
Plumbing code updates and the use of the Water Demand Calculator as a tool to right-size domestic water systems and reduce unnecessary overspecification will be discussed. Motor efficiency classifications, including a technical comparison of IE3 vs. IE5 motors, will be explored along with their influence on wire-to-water performance. Intelligent operation strategies—highlighting Power Optimal Pump Sequencing (POPS) and efficiency-based staging—will demonstrate how smart controls can maximize efficiency across all load conditions, with specific focus on low-flow stability and advanced control methodologies. ASHRAE 90.1 will also be discussed.
The session will incorporate real-world case studies, consumption patterns, and performance data to validate theoretical concepts and guide practical decision-making. It will conclude with a review of system certification requirements, compliance standards, and the importance of interdisciplinary collaboration during early design stages to optimize CAPEX, OPEX, and long-term system reliability."
