"Well-designed domestic hot water recirculation loops are essential for sustainable, energy-efficient, and low-maintenance plumbing systems. High-rise construction complicates these objectives, particularly when managing recirculation across different pressure zones. To exceed performance goals, engineers must precisely select and apply pressure-reducing valves, point-ofdistribution mixing valves, and balancing valves. This session will:
• Analyze pressure-reduction zones
• Discuss point-of-distribution mixing
• Detail balancing strategies"
