SAPCalc.com Online Calculations
SAPCalc.com provides Accredited SAP Calculations, which on passing can be accepted by Building Control or Approved Inspectors without any further assessment.
SAP (Standard Assessment Procedure) Calculations are an assessment protocol for the energy performance of new residential premises, which from the 7th April 2006 have been required for all dwellings.
Why do you need a SAP Calculation?
With Governmental and Public focus on C02 emissions, Architects and Developers need to consider the impact that their designs are having on the environment like never before. Part L1a of the Building Regulations requires that SAP calculations are carried out on all new build developments to prove that they are not contributing excessively to carbon emissions. Each dwelling must demonstrate that it meets the Target Emission Rate as stipulated within the SAP calculation.

There are 2 stages for the SAP Calculations
The Design Stage is completed and submitted at the same time as your building control application to your Building Control Body or Approved Inspector. If there are changes to the specification after the Design SAP has been completed then the Building Control Officer or Approved Inspector may request that an amended Design SAP is submitted.
The As-Built Stage is calculated when the premises is complete. From the calculation a 'pass' Certificate will be produced for submission to the Building Control Officer or Approved Inspector.
Part L1A
Part L1A is to do with Conservation of Fuel and Power in new dwellings and is just one part of the Building Regulations in England and Wales. Since the government announced that it intends to reduce the UK's carbon emissions by 60% by the year 2050 there has been a concerted effort to look at ways of reducing emissions from within the built environment. 50% of the UK's carbon emissions can be attributed to the built environment so it stands to reason that the biggest cut backs can be made in this area. Part L1a contains the legislation that aims to make this happen.
There are five criteria which must be met to achieve compliance. One of these criteria is that the Dwelling Emission Rate should be equal to or less than the Target Emission Rate. This is achieved using the government approved calculation methodology, which in this case is the SAP calculation. Other factors that are covered by Part L1a include air permeability rates, restricting U values and limiting solar gains in summer.
EPC (Energy Performance Certificate)
The Energy Performance Certificate is now a mandatory requirement for all new homes completed after 6th April 2008. The certificate sets out the dwellings sap & energy efficiency ratings and also has a list of recommended upgrades in order of cost effectiveness. The certificate is required for the sale of the property.
SAP 2009 and the new Part L1A 2010
On 1st October 2010, new regulations for the SAP calculation come into force. While the essential concepts of the SAP remain intact, the overall effect of the 2010 SAP changes will be to set higher standards of energy efficiency in order for a pass to be obtained.
These increased standards are driven by the new Part L1A 2010 which aims to reduce CO2 emissions by 25% over the existing 2006 Regulations, which equates to a 40% improvement over a dwelling built to the 2002 levels.
As the demands that are made of house builders and developers become more and more rigorous, you will need to focus more closely still on your energy efficiency strategies to ensure that you achieve Building Regulation Compliance.
In addition, the SAP calculation process should become less mechanical in nature, and more of a consultative one between SAP assessor, client, and design team, to ensure that the optimum design strategy is being used.
At Sapcalc.com, we already adopt this approach. We use the SAP calculation to advise on different design options so that you hit your energy efficiency targets without wasting money.
We also integrate our SAP work into our Code for Sustainable Homes assessment service from the outset, so that two strands are consistent with each other.
As the new Part L makes standards ever more stringent, we are well placed to guide you.
