Methodologies for the Energy Rating Assessments of New and Existing Dwellings

Whether you require an energy assessment of a new home or an existing one, the methods of calculation are distinctively different:


RdSAP: Assessment of an Existing Dwelling

If your home is build before 2007, then our team of Domestic Energy Assessors will survey your home, carry out all needed energy rating calculations and will produce the "Existing Dwelling Energy Performance Certificate (EPC)". The government has introduced the RdSAP methodology for the energy rating assessment existing dwelling.

The process involves the following steps:


Full SAP: New Build Assessments or On Construction EPCs

If your home is build after 2007, and has no EPC already, then the latest building regulations in Northern Ireland require an "New Build EPC".
Also, any proposed new dwelling at design stage must have a projected EPC rating. This is usually submitted to Building Control for Approval. Various parameters, such as the Dwelling Fabric Energy Efficiency (DFEE) and Dwelling Emission Rate (DWR) are produced and compared to government targets . As soon as the new build is completed a revised EPC must be prepared that will ensure if and to what extend that the building was constructed as per the initial specification. During the process we calculate U values of the walls, ceilings and floors. The government has introduced the Full SAP methodology for the energy rating assessment of new dwellings and of dwellings created as a result of a change of use (i.e. commercial property converted to residential). The Full SAP method requires a lot more data input and consequently it is a more accurate, and a more time-consuming methodology.
