New
Build EPC is usually issued by authorised SAP
Assessors. Energy
assessment of buildings is determined using various methods, SAP or
Standard Assessment Procedure is used for determining energy ratings
for buildings that cannot be calculated using Reduced Data or RdSAP
methods. Basically RdSAP 2005 has been developed for the
introduction of the Domestic EPC, and more specifically for
existing dwellings.

SAP energy calculations are based on different
principles, and are used mainly to determine carbon index and energy
values for a New Build homes & property. A typical case would involve
property developers building new houses at a site.
The new
legislation requires that the housing developer provide an energy
performance certificate for the new homes being built commencing 2nd
quarter of 2008. A building completion certificate from building
control cannot be issued without a New
Build EPC being issued. New housing developments will be mostly affected
by this legislation.

The
developer should instruct a SAP Assessor to determine the energy
values for new build property, the assessor usually only requires to
be provided with the construction blue-prints and a list of the
materials used in the construction of the building to enable the
necessary calculations to be made using proprietary software. For a
listing of SAP Assessors in your local area please refer to New
Build SAP Assessors register. SAP calculations and methodology
information can be found at: SAP.
Any new buildings which contain air conditioning systems will
require energy assessment by Air
Conditioning Assessors.

The Target Carbon Dioxide Emission Rate (TER) has to be calculated
within the Standard Assessment Procedure (SAP). The production of
SAP Ratings and EPC will be sought by the following groups:
Architects - for all new dwellings, conversions, extensions and for
material change of use.
Housing Developers - of all new dwellings, conversions, extensions
and material change of use.
House Builders - of all new dwellings, conversions, extensions and
for material change of use.
Self-Build - of all new dwellings, conversions, extensions and for
material change of use.

By Local Authorities - all rented dwellings stock and affordable energy
measures.
In
addition, Housing Associations (RSLs) Registered Social Landlords -
compliance with Housing Corporations Scheme Development Standards
for both new and existing dwellings. Refer also to Social
Housing & Landlord
Rental Property Energy Performance Certificates.
Private Landlords by identifying improvement options and assisting
with access grants.
The cost of SAP Assessment is usually based on the size of the
dwelling or conversion. In all cases the SAP assessor must be
provided with details of the boiler, heating system and controls. In
addition the calculated "U Values" should also be
supplied. SAP Rating Compliance Certificates require that buildings
be Air tested to determine leakage. This can usually be arranged
through a local air testing contractor. The assessor does not
usually require a site visit to determine energy ratings, provided
that all the required information is available on a SAP Data Form.

are considering training as a SAP assessor please see SAP
Assessor Training.
