Building Performance Evaluation

The team is well-equipped and has the experience to carry out building monitoring and testing.

Co-heating tests, in which an empty building is heated to 25°C over a two to three week period, enable the as-built fabric performance to be assessed and compared with predictions, thus ‘closing the loop’ between design and practice. The test links the energy use of the building with external temperature conditions, producing a heating factor in Watts per Kelvin temperature difference. Logging equipment, weather stations, heaters, controllers, meters and fans are all kept in the laboratory.

Ongoing monitoring of occupied buildings can also be arranged, using the latest discreet wireless equipment to log temperatures, relative humidity and carbon dioxide concentrations. In addition, sub-metering of electricity use (for instance lighting circuits, fans and pumps) can be undertaken, alongside monitoring of external conditions, hot water flows and photovoltaics generation as necessary.

There is a unique linkage across groups in this area, with the Low Carbon Building Group specialising in post-occupancy evaluation. This enables user perceptions to be correlated to internal conditions and energy use, with consequent valuable lessons about the interaction of human behaviour and building performance.
