Buildings can behave badly, both in terms of energy and comfort. Understanding how buildings behave when they are in use is essential for managing energy use and improving efficiency. Building Performance Evaluation (BPE) can commence during construction or refurbishment to help to identify and mitigate risks. Through hand-over and operation, BPE can be used to develop strategies such that operational energy and comfort targets are met.
We use a range of techniques to audit and analyse the performance of buildings. These techniques can be selected as appropriate to the needs of the client and budget. These include:
- Design and construction (site inspection) audits
- Building fabric testing:
- Air permeability testing
- In-situ U-value measurements
- Thermographic surveys
- Ventilation airflow performance measurements
- Independent monitoring of comfort conditions and air quality
- CIBSE TM22 and DomEARM energy assessments
- Energy audit surveys: annual energy use and sub-hourly energy profiles
- Interrogation of building controls and plant commissioning
- Benchmark analysis of energy performance
- Semi-structured interviews with building occupants to understand their issues
Please get in touch if you would like to discuss your requirements with us.
