−	* The benefit of undertaking thermographic surveys to demonstrate the continuity of insulation is that it verifies that the construction details set out during the design of the building have been ~~following~~ during construction of the building. This gives confidence to the building owner/occupier that the building and its associated systems will perform as designed to meet the thermal comfort requirements and reduces the building energy consumptions due to the reduced losses through the building fabric. As such this can avoid expensive unexpected costs and failure to comply with Part L.	+	* The benefit of undertaking thermographic surveys to demonstrate the continuity of insulation is that it verifies that the construction details set out during the design of the building have been followed during construction of the building.

	* The survey can also act as a tool to determine areas of the building that could be made more energy efficient – reducing energy bills and improving the thermal comfort of the building. For example, on existing buildings, thermography can be used to assess the overall performance of the individual building fabric elements such that informed decisions can be made on improving energy efficiency. If required, in depth analysis can also be undertaken to estimate the potential cost and CO2 reductions if particular improvements are undertaken.		* The survey can also act as a tool to determine areas of the building that could be made more energy efficient – reducing energy bills and improving the thermal comfort of the building.

	The BREEAM criteria are not prescriptive on the approach that should be adopted and advice should be sought from the project team on which is appropriate given the nature and complexity of the building being assessed. The wording of the criteria suggests that a qualitative assessment would be sufficient to meet the credit requirements but there are benefits in undertaking a quantitative approach for more complex buildings that may justify the increased expenditure. It should be noted that, having completed a qualitative level survey, if a decision is subsequently made to follow the quantitative approach it is likely that the surveys would need to be redone as the level of detail required is increased.
