Requirements
for Energy Assessors for New Build Homes & Dwellings
|
|
SAP - or Standard
Assessment Procedure is the current method used to obtain
energy rating for new build homes or dwellings. The procedure
is used to determine heat losses and thermal characteristics
of the property by examining the building's plans, the
construction materials used in the build and additional
factors including space and water heating.
SAP
ratings are scored on a scale from 1 to 100 where 1 is the
worst and 100 will indicate no heating/hot water cost, it is
based on the annual energy costs for space and water heating. |
A Target
Carbon Dioxide Emission Rate (TER) has to be calculated within the
Standard Assessment Procedure (SAP). Carbon Index, on a scale of 0.0 to
10.0, based on the annual CO2 emissions associated with space and water
heating.
SAP Ratings are used to demonstrate compliance with building regulations
for dwellings - Part L (England and Wales). To produce the required energy
rating you will need to appoint a SAP
Assessor
SAP is based on a notional dwelling built to the 2002 standards with a
target reduction of 20%. The actual Dwelling Carbon Dioxide Emission Rate
(DER) must then be no worse than the TER. The new SAP 2005 incorporates
all these calculations.
The CLG has stated the following:
From the 6 April 2008 all new homes will require an EPC and Recommendation
Report when physically complete.
The EPC will be based on the SAP rating
which is currently required to comply with Building Regulations. This
demonstrates that new homes meet the targets for energy performance that
are part of the Building Regulations.
The EPC must be produced by an Energy
Assessor who is accredited for On Construction Energy Assessment. The
EPC is based on SAP rather than RdSAP
which is used for existing homes.
When the home is physically complete, an EPC
should be produced and given to the owner of the home. Building Control
will not issue a completion certificate until they are sure this has been
done.
If you are marketing a home off-plan, you will need to have a PEA
(Predicted Energy Assessment) in the HIP
to provide to potential buyers. Once the home is physically complete the
PEA in the HIP
should be replaced with an EPC and Recommendation Report.
PEAs should be based on the predicted SAP
rating for the home. This will be available from calculations done at
the design stage and is a number between 1 and 100. A spreadsheet template
is available to be able to represent the rating in a graphical form for
potential buyers.
Each building within a development will require its own EPC
(although reports can be cloned for identical dwellings and will not need
to be inspected individually).
An On
Construction Energy Assessor will not need to visit the property to
produce an EPC. The EPC will be the result of the As Built check which is
an extension of the SAP
calculation needed for Building Control.
For further information for building owners and or managers, including new
build property developers on what information you must provide to
assessors please refer to:
SAP Assessment - for new build "on
construction" dwellings.
SBEM Assessment - for existing
commercial buildings
EPC
Validity
For newly constructed homes (New Build Dwellings) EPCs are valid for
10 years. The CLG have made the following specific statement regarding the
sale and marketing of new dwellings with regard to the issue and validity
of the EPC.
|
|
"When a
dwelling is first put on the market, the EPC must be no older
than 12 months. However, if the dwelling is taken off the
market and then put back on, the same EPC can be used as long
as it is no longer than 12 months since the EPC was produced
and the dwelling was put on the market the first time. If the
dwelling is on the market for longer than 12 months
continuously, the EPC remains valid."
If you are
considering undertaking a course in the production of EPC's
using the above methods please refer to SAP
Training. |
What
Buildings will require a SAP Rating?
All new dwellings, conversions, extensions and buildings which are
considered as material change of use.
Where can I find a SAP Assessor?
We have compiled a directory of regional services, please refer to: Commercial
