We undertook the detailed design for a new build mixed use development consisting of 56 social housing units (rented and shared ownership) and 3 retail units on a former factory site in Chiswick. The scheme includes central boiler and hot water generating plant distributed throughout the building, with dual plate heat exchangers in each unit to deliver heat and instantaneous hot water to the individual dwellings. The dual plate heat exchangers also include energy meters so that consumption can be recorded and the residents charged accordingly. In addition, a large PV Array has been provided on the roof of the block which, combined with the CHP, achieves an overall on-site generation target of 21%. 

Due to the concern regarding the potential for overheating within the corridors because of the distribution pipework associated with the central plant solution, we undertook a thermal modelling exercise using Hevacomp to review where any potential overheating would occur. A ventilation strategy was then developed with the Architect to provide additional AOV’s controlled via thermostats to relieve heat build-up by natural means.
