We work proactively with developers and designers, undertaking preliminary SAP calculations to establish the required fabric performance before any working drawings are produced. This can save time and money for design and drawing production, as well as allowing time to discuss options and alternatives.
When working through SAP calculations, it is important that all options are explored and the most appropriate solution for the client is achieved. For some clients this may be the lowest capital cost, but for others it may be lower running costs, or a quicker payback period for measures installed.
You might think it’s just a case of getting the U-values right, but it’s not that simple. With the law of diminishing returns, it may not be practical or cost-effective to increase insulation provision, and other more carefully considered strategies may be required, such as thermal bridging details or heating options.
How much can be saved?
More than you might think. For example, on a recent six-flat scheme we were asked to review the recommended strategy that had been received from another SAP assessor. We found that they had not considered thermal bridging at all, or potential heating options, which meant they had significantly overextended the SAP requirements – and so recommended unnecessary expenditure totalling £16,450.

“I’ve found AJ Energy to be invaluable in controlling our capital expenditure on a scheme, thanks to their in-depth knowledge and rigorous process. They always make sure they undertake a full examination of all the options, and ensure that everything has been specified to optimise value while meeting regulatory requirements.”
