FAQ
What does SAP stand for and the meaning of SAP?
SAP stands for Standard Assessment Procedure and is the methodology used by the Government to access and compare the energy and environmental performance of dwellings.
What is a SAP assessment?
A SAP (Standard Assessment Procedure) assessment looks at the energy efficiency of a property and a SAP certification is required by building regulations for all new residential dwellings since 2012.
SAP assessments are calculated using information on the building fabric, area specific information, heating and hot water systems, lighting and renewable technologies. SAP reports are given a number rating/ points list from 0 (least efficient) to 100 (zero energy costs) to over 100 which means the property is a net-exporter (creates more energy than it uses).
SAP assessments do not require a site visit, but the Energy Assessor requires specific evidence to be sent in to accurately calculate the SAP result.
What is a SAP EPC?
A SAP Energy Performance Certificate (EPC) is a detailed document reflecting the building fabric and services of a dwelling and is a EPC for new build properties. A SAP report is more comprehensive than a standard EPC and thus gives a more accurate assessment. However it has some similarities as it lasts for 10 years and can be used for calculating the energy cost of the property. Once the SAP calculations have been completed the client will receive a SAP EPC, Compliance Report and a Data Input Calculation Sheet, which can be provided to Building Control and related parties (additional SAP documents can also be provided on request).
How is a SAP assessment carried out?
A SAP assessment normally follows these stages:
SAP Stage One: Design (Draft Stage):
The SAP Assessor uses plans provided by the designer/ architect to prepare the initial figures for the dimensions of the building including heat loss areas such as walls, flooring, roofing, windows and door openings. This allows the assessor to create U-values for each element and calculate the thermal performance of the building. This information along with the planned building services allows the assessor to calculate the Draft SAP result, which determines if the building will comply with current building regulations for energy efficiency (Part L). For new build properties we highly recommend that a SAP assessment is carried out at this stage as if recommendations are needed the architect can redesign elements of the building and get it verified with the energy assessor.
SAP Stage Two: Design (Final Stage):
This stage finalises the first stage, after a property design has gone through as many changes as necessary to meet the SAP requirements and has been signed off by the assessor, client and architect, The data is then finalised and submitted to produce a Predicted Energy Assessment report.
SAP Stage Three: Built (Draft Stage):
This is the stage where the SAP assessor will require an air pressure test conducted by a local air pressure technician. It is important that the SAP Assessor is aware of any variations in the result of the air pressure test from the specification. Some buildings will not require an air pressure test such as smaller sites with a standalone design, which can be assumed to have a figure of 15 m3/(h.m2). Once the air pressure test has been confirmed and the data has been entered, the assessor will check if results allow the building to pass or fail building regulations. If the latter than the assessor can advise on remedial action to bring the property back up to regulation. The assessor will also check that the building is registered on the Government central database of national property addresses. Whilst it is the clients responsibility to arrange for the property to be added to the register, this needs to be checked by the assessor and it is a requirement to finalise the assessment.
SAP Stage Four: Built (Final Stage):
Once construction has been completed, the assessor creates an EPC certificate. This is a legal requirement and will be accessible on a public register and is necessary for building regulations to issue a completion certificate. Building control will also require the SAP worksheet report and SAP data input report which will also be provided.
