Commercial Energy Performance Certificates (EPCs)

This is an important part of assessing how energy efficient a building is based upon the building fabric and installed heating, lighting and air-conditioning.  Our building services background makes us ideal for assessing large, complex buildings.

With Level 3 and 4 accreditation and experience in significant estates for public and private organisations, our team can take care of any of your requirements.

EPCs are now mandatory upon construction, sale, or rental of any non-domestic building, whether new or existing.  An assessment must be carried out by an accredited assessor. We at Axion Energy Solutions are accredited to produce both Level 3 and 4 Commercial EPCs.

We can also include thermal images of your property with the EPC, providing you with additional detail of where you are losing heat and identification of possible building defects.

Display Energy Certificates (DECs)

This is a legal requirement for buildings with a floor area of over 500m2, that are partially occupied by a public authority and which are frequently occupied by members of the public.

A Display Energy Certificate indicates the energy performance of a building based on its actual energy consumption and it shows how a particular building compares to others of similar use.

The DEC is produced with an accompanying advisory report which identifies the main areas where energy can be saved.

Having expertise in energy management makes us ideal for providing you with a DEC and an advisory report that has real meaning and offers practicable guidance for reducing your energy consumption.

For non-public buildings where there is no legal requirement to provide a DEC, it is an ideal low cost and simple method of identifying where energy can be saved in smaller or non-complex buildings. It is also an affordable method for undertaking an initial assessment of large portfolios of property.

SBEM calculations

SBEM (Simplified Building Energy Model) is a calculation of whether or not a new building meets the planning regulations. Our experience within the construction industry supporting various stakeholders means that we can deliver these in a supportive and efficient way.

Since April 2006, all new-build commercial buildings, and some extensions, require an SBEM calculation, in accordance with Part L of the Building Regulations.

We at Axion Energy Solutions are accredited to produce SBEM calculations and as-built EPCs.

From your drawings and specifications we will produce an SBEM calculation of the building’s CO2 emissions using approved software, which you can then submit with your Building Control Application.  Having Building Services Design experience makes us ideal for working with Architects in producing a compliant SBEM calculation.

SAP calculations

The Standard Assessment Procedure (SAP) is the methodology established by the Department of Energy & Climate Change (DECC) to assess and compare the energy and environmental performance of homes.

We have experience of working with housing developers to carry out this procedure to assess energy performance of housing during and on completion of the development, ensuring compliance with Part L of the Building Regulations for England and Wales. You can also use it to assess the performance of alternative building designs.

The SAP shows you 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 different housing.

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. These indicators of performance are based on estimates of annual energy consumption for the provision of space heating, domestic hot water, lighting and ventilation. Other SAP outputs include estimates of appliance energy use, the potential for overheating in summer and the resultant cooling load.
