If you're working on a new build construction, whether for commercial or residential purposes, it's vital that SAP calculations and EPC certificates are provided to ensure the property is the most energy efficient it can be. Falcon Energy, experts at energy conservation, have a range of services on offer to help new build projects including SAP Calculations and Energy Performance Certificates across Sussex, Surrey, Kent, London and the UK.

SAP Calculations

SAP Calculations are a key component of any new build project to establish carbon emissions and subsequent energy costs of the property. These emissions are linked to ventilation, light, heat and hot water and need to be considered at the very beginning of a build, ideally at the design stage.

Today, SAP Calculations are a requirement of the Building Regulations in the UK and can be a challenging aspect to a new build, especially if you're new to such construction. Whether you're building a property from scratch, are converting or extending a current build, SAP Calculations cannot be overlooked.

Frequently Asked Questions

What is a SAP Calculation?

SAP or “Standard Assessment Procedure” is a Government approved procedure used to provide an energy rating for domestic properties.

It results in energy certification and a rating between 1 and 100. The higher the rating, the more energy efficient a dwelling, and with renewable energy it is possible to exceed a 100 rating.


When is a SAP calculation required?

Under current Building Regulations, a SAP calculation should be carried out when new residential properties and developments are constructed, and when existing homes are converted or extended.

SAP calculations are presented in the survey for homeowners when buying a property. To a degree, it is possible for results to can affect the appeal of a property when selling.


How do you calculate the energy rating?

Before the property is completed, assessors calculate the Target Carbon Dioxide Emission Rate (TER) that the property. This rate details how much CO2 it is permitted to emit, and is a minimum standard for its energy performance.

The next stage is using the actual design of the property to calculate the DER or Design Carbon Dioxide Emission Rate. In all instances, the DER should be lower than the TER so it can be approved within the predetermined environmental limits.

After construction a final calculation is made; the ‘As Built DER’. This assessment ensures the property has an acceptable level of CO2 emissions.


When should I have the assessment done?

The test should be carried out before the property is being constructed, as it may identify that the plans aren’t adequate and need to be changed to pass Regulation 26 of the Building Regulations. Once construction has started, it is considerably more expensive to amend the design.

We carry out our SAP and EPC tests before construction to give you flexibility in materials and costs and to ensure you have the best advice and information going into the project.


What is an EPC?

An EPC is an Energy Performance Certificate (EPC) which is given to potential buyers or renters of a particular property. The EPC report covers the energy efficiency of heating and lighting and shows the estimated C02 emissions.

For potential buyers, it shows them how much they may spend on energy bills, how much energy waste the property potentially has and whether the rating can be improved. Each EPC gives a property a rating from A to G; A is the most efficient rating and G the least efficient and would be more common in older properties.


When is an EPC required?

An EPC is the industry standard in building and is defined clearly by legislation. All new build properties need an EPC in their pack for potential buyers. They are also required if a property is changing its purpose, such as a commercial property becoming domestic, as well as any residential property built from 6th April 2008.

With new build properties, the EPC’s can only be conducted by On Construction Domestic Energy Assessors (OCDEA’s). This is part of an accredited Government approved scheme.


What is OCDEA?

An OCDEA is an authorised On Construction Domestic Energy Assessor (OCDEA) who can test and create a verified EPC for inclusion in Home Information Packs for new build, domestic properties.

Since April 2008, this has been a requirement for all new build domestic dwellings and tells new homeowners how energy efficient their new property is. All new properties should take environment and energy performance into consideration when being built and upgraded.


What other certificates are involved?

A Predicted Energy Assessment is produced before a property has been built and is a certificate produced alongside the Design Final SAP calculation.

This is required for properties being sold off plan before the final EPC has been created for the buyers. It will then be replaced with the EPC when available.

Again, the PEA can only be completed by OCDEA’s.
