What is an EPC?
The Government is complying with the Energy Performance of Building Directive (EPBD) with the introduction of the Energy Performance Certificate. The EPC shows a record of the energy efficiency levels and CO2 emissions of a building, by using a standard table from A to G (A being very efficient, G being very inefficient).
Firstly, the energy survey is performed by a qualified energy assessor who visits the property and examines key items within the premises such as loft insulation, domestic boiler, hot water tank, radiators, windows for double glazing, etc. Once this information is obtained it is then placed into a software programme which carries out and calculates the level of energy efficiency and CO2 emissions.
This programme then proceeds to generate the level of energy efficiency in the property, with a recommendation report on the ways to improve the energy ratings by using cost effective and low and zero carbon generated systems. This will help improve your energy levels and ensure future savings on fuel costs.
There is a similar report which provides figures on the environmental impact. This report shows a table of estimated energy bills per annum and the potential for improved and lower fuel costs, but without any reference to the actual householder bills.
SBEM and SAP
There are three types of EPC assessment:
- RdSAP – Used to carry out existing dwelling EPC assessments.
- SAP – New-build / Conversion domestic dwellings
- SBEM – Commercial builds
Essentially, if you’re doing a new build or a conversion to existing homes. you’ll need an SAP assessor to work on your EPC assessment. If you’re working on commercial builds instead, you’ll need an SBEM assessment.
At Shire Group, we’re highly experienced with SBEM and SAP calculations and can get you the certification you need. Speak our team and get an SBEM or SAP assessor today.
Who requires an EPC?
As of the 21st May 2010, if you decide to place your property on the market for sale or rent in England and Wales you will need to purchase an EPC.
Who is responsible for obtaining an EPC?
With a new build it is the responsibility of the person carrying out the work. They must provide the owner with the certificate and inform the Building Control Officer or Approved Inspector that this has been completed within the specified time.
When you are selling or renting your property, you, as the seller or landlord must provide the EPC. The certificate is available free of charge and should be given to the prospective buyer or tenant prior to entering into a sale or lease agreement.
The householder will have to pay for this survey and we offer extremely competitive prices.
The survey is entirely non-invasive as the information provided to the assessor is given directly from the householder. For example, whether the property has cavity wall insulation or not, even when there is no evidence of drill holes present.
Part L compliance
To demonstrate compliance with the Building Regulations Part L, all new non-domestic buildings, some extensions and conversions require assessments through SBEM calculations.
Using an approved SBEM software, the CO2 emission of a building can be calculated based on the building specifications. This CO2 emission is referred to as the Building Emission Rate (BER). For a building to be compliant with the regulations, the BER must not be greater than the TER (Target Emission Rate).
SBEM Calculations are carried out in two stages: Design Stage & Built Stage.
