CIBSE NW: Cold Water Pressure Boosting

Presnted by Geoff Ball - National Account Manager for Xylem Water Solutions UK Ltd - This CPD presentation delivers a concise yet thorough overview of variable speed cold water boosting, explaining why booster systems are essential in modern buildings—particularly high‑rise and multi‑occupancy developments affected by low or variable mains pressure. It covers system purpose and components, UK regulatory requirements, demand assessment, flow and head calculations, and correct pump set selection, with emphasis on BS EN 806 methodology. The presentation highlights the key benefits of variable speed technology, including energy efficiency, constant pressure, reduced noise and maintenance, improved reliability, and smart BMS communication, while also addressing real‑world challenges such as pressure zoning, water hammer, safety features, and commissioning considerations to ensure compliant, efficient, and user‑comfort‑focused system design.
