AMO SIHRA - COMMERCIAL & RESIDENTIAL ENERGY ASSESSOR
ENERGY PERFORMANCE CERTIFICATES - EPC's
An EPC is only required for a building when constructed, sold or let.
Domestic EPCs
The energy performance of existing dwellings is determined using a government approved domestic energy model known as Reduced data Standard Assessment Procedure (RdSAP). This is a streamlined version of the Standard Assessment Procedure (SAP) into which data for new build dwellings is entered based on drawings and specifications.
RdSAP has been developed to use data from an on-site survey of an existing dwelling, enabling consistency whilst limiting the required data collection and survey time required by the energy assessor.
The RdSAP model takes account of a wide range of features in a property, including the age and dimensions of the property, the building materials used to construct the dwelling and whether it has single or double glazing. It also takes into account the manner in which the heating and hot water are provided (fuel and system type including make and model) and the type of fixed lighting. The RdSAP model has been incorporated into several government approved software packages. Such software also generates the certificates and recommendations report.
Non Domestic EPCs
An Energy Performance Certificate (EPC) is intended to inform potential buyers or
tenants about the energy performance of a building, so they can consider energy
efficiency as part of their investment or business decision to buy or occupy that
building.
Energy Performance Certificate (EPC) is intended to inform potential buyers or tenants
An EPC will provide an energy rating for a building which is based on the
performance potential of the building itself (the fabric) and its services (such as
heating, ventilation and lighting). The energy rating given on the certificate reflects
the intrinsic energy performance standard of the building relative to a benchmark
which can then be used to make comparisons with comparable properties. It is
accompanied by a recommendation report, which provides recommendations on
how the energy performance of the building could be enhanced, together with an
indication of the payback period.
