Construction Energy Assessment Services

Construction Energy AssessmentWe are able to offer a full construction energy assessment service which critically includes advice on both fuel reduction methods and how to make designs more economic to achieve the intended energy ratings.

In order to maximise this it is important that we are involved at the earliest stage possible so that maximum efficiencies can be made.

There are various areas of energy calculations we are involved in.

  1. SAP Calculations for New Built homes,
    Conversions and Extensions.
  2. RdSAP’s for existing homes.
  3. SBEM Calculations for commercial Properties.


Standard Assessment Procedure (SAP) Calculations

Construction Energy AssessmentNew Constructions

Since 1995 it has a been a requirement that all new dwellings have SAP home energy rating calculations prepared in order to demonstrate to local building control bodies that the proposed dwellings meet the standards of the prevailing building regulations with regards to the conservation of fuel and power.

Extensions/Change Of Use

In addition SAP calculations may also be required in order to support building regulations applications for existing dwellings – for example, when an extension is being added, or when a building undergoes a material change of use or material alteration.

Construction Energy AssessmentBased upon plans, drawings and specifications provided by clients we are able to:

  • Offer advice of construction materials and specifications
  • Target carbon dioxide emission rate/dwelling carbon dioxide emission emission rate calculations
  • SAP calculations for new build properties in England and Wales under Part L1a of the Building Regulations covered by SAP 2001, SAP 2005, SAP2009
  • SAP calculations for extensions to existing dwellings and material change of use on England and Wales under part L1b of the building regulations
  • Calculate u values of the building elements
  • Predicted Energy Assessments (PEAs)
  • Energy Performance Certificates (EPCs)
  • Dwelling annual fuel costs
  • Water Efficiency Calculations


SBEM is for non domestic buildings in correlation with the Green Deal & Energy Performance of Buildings Directive (EPBD). It is used to measure CO2 emission rates for new buildings to keep you in compliance with Part L of the Building Regulations. SBEM Calculations are also used to supply Energy Performance Certificates for non-domestic buildings.
