This listed Edwardian Building had south-facing rooms, with significant fenestration, overheating in the summer. Once temperatures had risen, windows were opened introducing traffic pollution in the form of both noxious gases and noise.
The client’s brief was to find a green cooling solution which would appease Historic England and the planners. As part of the project the 50-year-old heating also had to be renewed.
Following dynamic simulation modelling and an options appraisal we made use of the existing internal thermal mass and redundant fire place grilles along with new metallised blinds to demonstrate we could provide mixed mode ventilation in compliance with Building Bulletin 101.
During the summer months the BMS-controlled strategy utilises night cooling utilising purer outside air from roof level and avoiding the production of 7.4 tonnes per annum of CO2 which would have otherwise occurred with comfort cooling.
