Case
Edinburgh university decarbonises student accommodation, cutting 150 tons of CO₂ annually
Heriot Watt University is racing toward net zero emissions by 2035 by transforming how it generates energy and heat across campus. At Lord Home Hall—a 200-room student accommodation block on the Edinburgh campus—the university has replaced old gas boiler technology with a Nova 220kW heat pump to deliver heat and hot water to residents.
∼ 64%
decrease in CO₂ emissions
261 tons
annual CO₂ emission reduction
Challenge
· Support the university’s ambitious ClimateAction Framework.
· Hot water and heating (25:75 split) provided bygas boiler technology.
· Provide a quiet and reliable source of heatingfor 200 rooms.
Solution
· Direct replacement of boiler technology with a NovaSeries heat pump solution.
· Compact modular design providing discrete andquiet outdoor installation.
· Centrally controlled modules supplying a 220kWdelivery at full duty.
Result
- Complete removal of fossil fuel heating technology from the building.
- ∼ 64% decrease in CO₂ emissions.
- Expected annual reduction:150 tons.
"The pilot heat decarbonisation project at Lord Home Hall represents a significant step towards enhancing our sustainability efforts at Heriot-Watt University. Already, we are seeing significant carbon savings, and are pleased to report that the building is operating efficiently at a comfortable temperature using the air source heat pumps.”
