Could the heat from 90,000 concertgoers be reused? In this informal thought experiment, young engineer Sophie Sibley uses Taylor Swift’s Wembley shows to explore the potential scale of occupant heat gains and how ambient heat networks might make use of low-grade, intermittent energy.

Hot-water boost to heat network efficiency
Jacobs has designed a Generation 4.5 heat network that uses an innovative boost electrode to deliver domestic hot water, allowing the system to operate efficiently at a 45°C flow temperature for 80% of the year. The company’s Adam Selvey FCIBSE explains how it works
The hidden cost of poor pipework insulation
Pipework thermal insulation is often overlooked, but can have a devastating impact on system performance if not specified, installed or maintained correctly. Kaizen Energy Consultancy’s Lawrence Leask and TICA’s Chris Ridge say following insulation best practice is a low-hanging fruit when it comes to HVAC efficiency
Testing the limits: lowering operating temperatures
Lowering operating temperatures will be essential if existing buildings are to plug into the next generation of heat networks. FairHeat’s Simran Chaggar drops the boiler setpoints in two commercial buildings to see how they cope
Turning waste into warmth: how data centres can heat tomorrow’s cities
Aecom has helped develop a vast energy centre in West London that will pipe waste heat from data centres into 10,000 new homes and existing businesses via a heat network. The company’s Asad Kwaja looks at the ‘architecture’ behind the design
