Methods used in BPE studies

Combining quantitative and qualitative data collection to create socio-technical approach to studying building performance. BPE studies include:

  • collection and analysis of information on energy performance,

  • environmental conditions,

  • building fabric performance,

  • systems integration and commissioning,

  • handover and operation, as well as

  • qualitative feedback from building owners and managers, design and construction team, and occupants.

The studies involve a variety of data collection methods including:

  • Design and construction audit: including drawings and SAP calculation review; interviews and walkthrough with design team; photographic survey; review of control interfaces.

  • Building fabric testing: including thermographic survey; airtightness test; U-value testing.

  • Commissioning and handover review: which includes commissioning checks of systems and services; MVHR tests; review of handover process and occupant guidance.

  • Energy monitoring and assessment: including smart metering and submetering; energy audits such as DomEARM and benchmarking.

  • Monitoring of environmental conditions: including temperature; relative humidity; CO2 levels; window opening.

  • Occupant studies: which includes occupant satisfaction survey using BUS questionnaire survey; interviews and walkthroughs with occupants; activity logging and thermal comfort diaries.
