If energy efficiency measures have been made, particularly if there have been multiple fabric interventions, monitoring the works and continuing a programme of general maintenance of a building is vital to maintain efficiency.

There needs to be an understanding of whether the objectives of the project have been achieved and if the comfort levels of the occupants have been improved, or if further works need to be undertaken.

Monitoring will help assess whether the energy efficiency measures are failing. For instance, if there are any visible signs of damp, this must be addressed as soon as possible as there will be the build-up of moisture that may be impacting indoor air quality, which can affect the occupant’s health, as well as resulting in adverse impacts to the built fabric.
