SAP Calculations and Reports
The Standard Assessment Procedure (SAP) is the methodology used by the Department of Energy and Climate Change (DECC) to assess and compare the energy and environmental performance dwellings. The SAP is mandatory under Regulation L of the building regulations for newly built dwellings, which include any new dwelling that is formed either by construction or by conversion.
Its purpose is to provide accurate and reliable assessments of a dwelling’s energy performances. SAP works by assessing how much energy a dwelling will consume and how much carbon dioxide (CO2) will be emitted in delivering a defined level of comfort and service provision, based on standardised occupancy conditions. This enables a like-for-like comparison of dwelling performance.
SAP quantifies a dwelling’s performance in terms of: Energy use per unit floor area, a fuel-cost-based energy efficiency rating (The SAP Rating) and emissions of CO2. We work alongside approved SAP assessors to provide all the technical input into the design process in order to submit to the body who is providing you with the Building Regulation approval.
SAP EPC Reports are required on all new dwellings to show compliance under the current building regulations. They are produced using a combination of approved software and technical calculations. Laurence Associates are qualified SAP Assessors and are able to produce the following elements to produce the final SAP EPC Reports required.
Design Stage -Predicted Energy Assessment (PEA)
Completion-On Completion Energy Performance Certificate (OCEPC).
How it Works
SAP works by assessing how much energy a dwelling will consume when delivering a defined level of comfort and service provision. The assessment is based on standardised assumptions for occupancy and behaviour. This enables a like for like comparison of dwelling performance. Related factors, such as fuel costs and emissions of carbon dioxide (CO2), can be determined from the assessment.
A SAP Calculation indicates a score from 1 to 100+ for the annual energy cost based on:
The elements of the structure
The heating and hot water system
The internal Lighting
The renewable technologies used in the home.
Residential Developments
SAP EPC’s for newly built or converted or extended residential dwellings are required to be submitted to building control to ensure compliance with Building Regulation Part L. There are different elements to the Part L Regulations which we can provide SAP Calculations for.
Part L1A For Newly constructed Buildings;
Part L1B For existing buildings (refurbishments);
Part 1LB For highly glazed extensions.
From June 2023 all new planning applications for new build residential properties including annexes (excluding conversion schemes), to accompanied with SAP Assessment and Energy Statement to demonstrate compliance.
