Performance gap in domestic retrofits
The energy efficient retrofit of existing building stock has been identified as one potential pathway to a low-carbon future. However, how do we know whether or not we have been successful in reducing energy demand? The lack of evidence for some major retrofit projects in terms of monitoring data represents a missed opportunity in fully understanding what works and whether retrofit is achieving its objectives.
This commentary focuses on only domestic retrofit. After introducing the topic, the section covers:
- modelled energy consumption versus actual performance
- energy monitoring
- fabric investigations and
- points for discussion, conclusions and further reading.
This section is maintained by Professor Richard Fitton MRICS of University of Salford.
