Commercial Energy Performance Certificate
Since the prices for energy will definitely increase in the future, energy saving and cost reduction have become more relevant than ever. Although investments in energy saving measures have not been a priority so far, the long term benefits of such measures should be taken into consideration. Energy improvement measures can have as an outcome important savings and they can stop energy costs from growing. This is why the epc is necessary, not only for commercial buildings but for all house owners.
Commercial EPCs have become a must for commercial premises because potential buyers and tenants are entitled to an impartial overview of energy use and energy costs of the building and because the epcs will tell sellers and landlords where there’s room for energy improvement as far as their properties are concerned. Such a certificate is valid around ten years, being not only a mandatory requirement but also a highly effective measure.
The commercial epc certificate enables investors and occupiers to compare the energy efficiency of buildings and to make their decisions after they have seen the epc. Due to the commercial epc, the commercial property sector will benefit from: a visible, quantifiable and mandatory energy performance certificate and an accurate comparison of energy efficiency of several commercial properties. These factors should change the perspective of the ones who invest in commercial properties due to the costs of utility which service those buildings.
The commercial epc can be given only by qualified non domestic assessors who are accredited. We are a commercial EPC provider. This certificate will be required upon construction, sale or lease for all non-dwellings, including retail units, office, industrial units, commercial buildings, warehouses, supermarkets and houses in multiple occupations. In order to receive such a certificate you will need to divulge the following information: floor plans in digital format, elevations and roof plans, details of the building’s construction and details for the building services elements
- Other building – Level 3.
- Building with heating systems over 100kw, cooling systems greater than 12kw and natural ventilation – Level 4.
- Large buildings over 10,000 m2 as well as smaller buildings that have particularly complex feature such as curved fascias, atriums and complex service systems – Level 5.
The NDEA’s job encompasses a number of areas.
The data required to allow the calculation of an EPC includes the following
- Built form.
- Number of storeys.
- Date built.
- Property dimensions including average floor to ceiling heights.
- Wall construction and any areas that are of an alternative construction.
- Roof construction.
- Openings (windows and doors) and their age.
- Percentage double glazed.
- Presence of secondary heating sources – i.e., different heat source.
- Heating system – type and fuel used.
- Boiler (manufacturer, model and ID number)
- Heating controls – room stats, programmer, etc.
- Water heating system and if applicable capacity and insulation for hot water cylinder.
- Electricity & Gas meter.
- Type of lights.
- The appropriate NCT file (for SBEM generated assessments)
- Aerial view(s) from Google maps or equivalent
- An appropriate and comprehensive method statement
- A complete set of comprehensive data collection forms, down to individual envelope level
- Comprehensive site notes, including floor plans, zoning methodology, full HVAC details including establishment of efficiencies, construction details etc.
- A comprehensive set of dated images that, together with the site notes, provides a full evidence trail to support all data entry for the SBEM model.
- Correct use of the EPC/EPBD audit information section
- Audit checking procedure
- In order to fulfil the required audit process, the Compliance team will be checking the integrity of the following items on all reports:
- Is he number and type of zone specified sufficient to adequately describe the building correctly in accordance with SBEM requirements?
- Has the assessment been carried out at the correct level, i.e. Level 3 or Level 4?
- General information
- Weather location.
- Stage of analysis.
- Correct level of assessment.
- Metering provisions.
- Power factor.
- Air permeability.
- Thermal bridging.
We strive to achieve turnaround of between 2~3 working days from instruction to production of the Commercial Energy Performance Certificate. We also understand that at some point only very short notice can be given for the production of the CEPC and it’s critical that the certificate is ready on time. In these circumstances we try to ensure the certificate is produced within the client’s timescale. This certificate is valid for 10 years or until changes occur.
In order to produce CEPC’s it is first necessary to visit the premises. These surveys can only be carried out by Non-domestic assessors. At Complete EPC we employ our own assessors, who hold all the necessary qualifications, experience and accreditation including Insurance and Disclosure checks, to enable them to produce Commercial EPC’s.
The data gathered during the survey is then used to run the commercial EPC calculations using the government approved software [SBEM]. The total heat loss is worked out for all the thermal elements of the premises and this is then combined with the efficiency of heating, lighting and air conditioning systems to work out the overall rating.
This rating is called an Asset rating, the asset rating is shown in graphical format on a scale of A (most efficient) to G (less efficient) and includes a numerical value. These rating can then be used to make comparisons with comparable buildings.
When an EPC is provided it is also accompanied by a recommendations report, which provides recommendations on how the performance of the building can be enhanced, together with an indication of the likely payback period.
EPC’s are not required for some type of buildings: such as places of worship, those that are stand alone and low energy demand and less that 50m2 and any that are scheduled for demolition.
EPC’s have been introduced to help improve energy efficiency of buildings. Since October 2008 it has been a legal requirement that commercial and public buildings must have one, whenever a property is sold, built, rented or leased. This certificate should be made available as soon as marketing commences.
The landlord and sellers/vendors has the responsibility for providing the EPC with the building particulars at the time of sale or lease. The requirements are enforced by Local Trading Standards Officers, who have the powers to fine, for non-compliance: typically 12.5% of the rateable value of the building to a maximum of £5000.
