Places for People were able to reduce design capacity to 400kW for the entire scheme, and, following the first year of full site operation, they confirmed that the actual heat load never reached over 300kW. This compares with typical network oversizing of up to 300-400%. This was a significant CAPEX saving, in the region of £1,600 per home.
As well as solving the oversizing problem using, real world data enabled commissioning with live information and ongoing monitoring of network performance.
Having real time data meant that Places for People could deliver against design. This was important to get right in the commissioning phase because after the contractor has completed handover and dwellings are occupied, access is costly and complicated. The Guru Systems hubs in each home also provided tenants with details of their energy usage.
