Lean System Design (LSD) for Schools

The presentation outlines a comprehensive design strategy for school heating, domestic hot water, and ventilation systems, emphasising the importance of ensuring that schools are designed to be heat network ready and how that can be delivered.

Learning Points:

• Discussion on heat network readiness and 60/30 ΔT compatibility, alongside targets for public building connection by 2050.
• Energy efficiency hierarchy: Be Seen, Be Lean, Be Clean, Be Green.
• Current energy consumption in schools and Department for Education targets.
• Justification for 60/30 ΔT designs, highlighting higher flow temperature and wider ΔT compared to typical heat pump designs.
• Optimising thermal storage for capacity and peak demand reduction.
• Risk mitigation through legionnaires prevention and reliable heating system balancing.
• Achieving low return temperatures and integrating mechanical ventilation with heat recovery (MVHR) for reduced heat loss and cost savings.
• Importance of monitoring for comprehensive data collection and implementation of soft landings for smooth transition and performance optimisation.
• Benefits of holistic design of energy centre and ventilation, including financial implications, and detailed system examples.
