- A district energy station consolidates heat from a nearby factory's exhaust and a natural-gas CHP module. A seasonal storage buffer shifts summer cooling reject heat to winter heating. Building substations use plate exchangers to isolate the network from occupant loops.
- Indicator Result Share of heat from recovery plus CHP about 78% Network return temperature Reduced 12°C vs baseline CO2 vs separate boilers minus 61%
- Low return temperatures were the single biggest lever — they raised the usable recovery fraction from the industrial waste heat recovery case nearby. The CHP unit followed the heat demand, exporting power only when the grid price justified it. For a smaller, single-building view of the same principles, see CHP case study. District schemes scale those ideas across many consumers sharing one recovery backbone.
티his district energy case study summarizes a representative low-carbon heating and cooling network that supplies a mixed urban district from recovered industrial waste heat plus combined heat and power (CHP).
