There was good co-operation between the commissioning consultant, the services consultant, the main contractor, and the principal sub-contractors. This resulted in a smooth handover and swift resolution of defects.
This project has also benefited from a well-informed client with a good relationship with the design team. The design team for this building have worked on other campus projects, and are working together on new projects.
The arrangement has allowed for lessons learned to be passed on to newer buildings. Issues have been dealt with quickly as the team are still in regular contact with each other.
The metering of Edge Hill has also been effective, which is a great help when judging the performance of a system during and after commissioning. This is a marked difference from many of other Carbon Trust's Low Carbon Building's Programme (LCBP) case studies, where metering was installed to gain BREEAM credits but with little thought put into commissioning them correctly. In many cases the sub-meter readings do not add up to that recorded by the main incoming energy meters.
Relying on BMS readings can lead to even greater disparities, with factors of three between the BMS readings and the sub-meters. Commissioning needs to include a proper reconciliation exercise before any monitoring begins.
BSRIA provides accredited BREEAM assessments as well as commissioning support, including specialist instruments, guides and training.
