Retrofit Revisit is an important building performance evaluation project to inform the UK’s approach to improving our housing stock and contribute to our net zero objectives. This publication details a building performance evaluation of 10 retrofitted homes, carried out approximately 10 years after the original retrofit works. It aimed to gather lessons on retrofit and on BPE techniques.

On retrofit:

• What has stood the test of time?

• Are there any new lessons on how to carry out retrofit projects?

• Topics of particular interest included (but were not limited to): energy demand, moisture, insulation options (moisture and combustibility), degradation of original solutions (e.g. airtightness).

On BPE techniques:

• What can be learned in a relatively short and non-intrusive manner, from individual BPE techniques or packages of several techniques?

• Where are more specific or detailed BPE techniques useful? How can some BPE techniques being, or newly, developed help?

The sample of 10 homes was as follows:

• Six were part of the 2009 Retrofit for the Future programme. All were considered best practice or exemplar at the time, and employed a whole house 'deep' retrofit approach.

• Six were pre-1919 properties.

• Nine were houses, one a flat.

• Some were tenanted from housing associations, others occupied by private owners.

• The insulation strategies and properties varied, with a mix of external, internal, and cavity insulation and of permeable and impermeable materials.

• Heating, hot water and ventilation systems were very varied across the sample.
