Concern & action: Monitoring and feedback required

Due to complexity and uncertainty of certain measures, monitoring and feedback is needed to provide information about their effectiveness and to reduce long term risks. Checks and processes are needed to ensure that measures are installed correctly and are working properly and not creating any adverse results (e.g. excess energy use, mould growth). They can include visual checks, meter readings, probes, thermographic survey or more detailed investigations.

Suggested actions

Before Implementation

Establish the need for monitoring at the design stage and define areas of specific concern. Develop a strategy for long term monitoring (minimum four years post refurbishment) and regular reporting on various conditions (e.g. fabric, comfort, air quality) especially at known vulnerable points (e.g. embedded timbers, cold bridges). This monitoring needs to take into account local weather conditions at site.

During implementation

Allow for the installation of monitoring equipment during the construction phase. Conduct a series of on completion tests e.g. thermographic survey, air tightness test, commissioning checks to ensure correct installation of materials/equipment. Establish need for any regular monitoring checks such as visual checks, spot moisture readings, thermographic survey check, and establish who is going to carry them (specialist or occupant). Prepare a response plan for possible outcomes of the monitoring. Prepare targeted advice to occupants to keep a watchful eye on conditions (air quality, mould build up in bathrooms) and to seek advice if uncertain

After implementation

Carry out the regular monitoring checks agreed during implementation of the measures and check any feedback from occupants. Implement the response plan with regard to the in situ monitoring and reporting e.g. increasing ventilation if conditions found to be deteriorating, including in the worse case a mitigation strategy which can include the removal of harmful measures. Report results to add to knowledge about refurbishment measures (e.g. monitor wall fabric condition (heat and moisture behaviour)).
