building performance evaluation

This paper describes the findings and recommendations of a meta-study examining the actual in-use performance of whole-house mechanical ventilation heat recovery systems (MVHR) installed in 54 low energy dwellings in the UK, as part of a national research programme. The performance of the systems is assessed using monitored data on indoor air quality (temperature, relative humidity, CO2) and energy use, cross-related with actual experiences of operating these systems through resident surveys.

This paper investigates the effect of occupant behaviour and expectations on energy use and indoor environmental conditions of six case study dwellings in three sustainable social housing developments in UK using building performance evaluation methods. The case study houses cover a variety of built forms and different types of construction systems but have similar occupancy profiles and tenures.
