Energy Assessment Types

Energy assessments are crucial for understanding a building’s energy performance and identifying areas for improvement. Different types of energy assessors are responsible for assessing different types of buildings.

Existing Domestic/Residential Buildings

Domestic Energy Assessors (DEAs) conduct energy assessments on houses, flats, and bungalows. They gather property data and information on site, which is then fed into approved software to generate an energy assessment report.

Non-Domestic/Commercial Buildings

 Non-Domestic Energy Assessors (NDEAs) handle energy assessments for non-domestic buildings, including offices, shops, and others. Similar to DEAs, a significant portion of their work involves on-site data collection. For assessments of new-build and complex commercial buildings, higher-level NDEA qualifications are necessary.

Energy Assessment

New Domestic Buildings

On-Construction Domestic Energy Assessors (OCDEAs) are responsible for energy assessments of new-build domestic properties. Their energy calculations are required both before and after construction. Their work is entirely desk-based, utilizing building plans and elevation drawings. 

Public Buildings

Display Energy Certificate (DEC) Assessors carry out energy assessments on public buildings frequently visited by the public, such as churches and libraries. Their work involves on-site data collection and analysis. Leveraging sophisticated, approved software, these assessors execute intelligent calculations (all sanctioned by the government) to assess the building’s energy performance. Once the assessment is over, they issue an Energy Performance Certificate (EPC).

What’s EPC?

An Energy Performance Certificate (EPC) is a legal document that provides information about how energy-efficient a building is. It is mandatory for all buildings that are being sold or rented in the country. The EPC rating goes from A to G, with A being the most energy-efficient and G being the least energy-efficient. Energy Performance Certificate (EPC).

Energy Performance Certificate (EPC)

The EPC is based on a calculation of how much energy a building uses to heat, cool, and light it. The calculation takes into account several factors, including the type of building, its size, its insulation, and its heating system. The EPC also provides recommendations for how to improve the energy efficiency of the building.

How Is the EPC Calculated?

Below are the steps through which ECP is calculated;

Standard Assessment Procedure (SAP):

The EPC calculation is based on the SAP, a government-approved methodology in the UK.

It considers various factors that affect a property’s energy performance, including:

    • Construction: Type of walls, roof, floors, windows, and insulation.
    • Heating and hot water systems: Type of system, fuel used, efficiency, controls.
    • Lighting: Type of lighting, energy efficiency.
    • Ventilation: Type of ventilation system, efficiency.
    • Renewable energy: Any renewable energy sources, such as solar panels.
    • Location and exposure: Geographic location, exposure to wind and sun.

Data Collection

  • An accredited energy assessor visits the property to collect data on these factors through:
    • Visual inspection
    • Measurements
    • Questionnaires
    • Reviewing existing documents (e.g., building plans)

Calculation and Rating

  • The assessor inputs the data into SAP software, which calculates:
    • The property’s energy efficiency rating on a scale of A (most efficient) to G (least efficient)
    • An energy efficiency indicator (EEI), a numerical score representing energy performance
  • The EPC document is produced, displaying the rating, EEI, and recommendations for improvement.

Validity

  • EPCs are valid for 10 years in the UK.


Once the EPC survey concludes, your energy performance is calculated, and an EPC Certificate is generated. Within 24-48 hours of the energy assessor leaving, the certificate is published on the government register and emailed directly to you. The EPC Certificate includes recommendations for enhancing your building’s EPC rating.

Calculating EPC rating

Why is EPC important?

There are many reasons why the EPC is important. Firstly, it helps to raise awareness of energy efficiency and to encourage people to improve the energy efficiency of their homes. Secondly, it provides information to buyers and private tenants about the energy efficiency of a building, which can help them make informed decisions about whether or not to buy or rent a property. Thirdly, it can help to reduce energy bills, which can save homeowners and tenants money. The factors that are included in the EPC calculation are:
The type of building: The type of building will affect how much energy it uses. For example, detached houses tend to be less energy efficient than terraced houses.
The size of the building: The larger the building, the more energy it will use. The insulation of the building: The amount of insulation in the building will affect how much heat is lost through the walls and roof. The heating system: The type of heating system and how efficient it is will affect how much energy is used to heat the building. The EPC can be obtained from a qualified energy assessor. The cost of an EPC will vary depending on the size and type of building.

Benefits of having an EPC

  • It will provide you with awareness about how much energy you use and waste in your house.
  • It can help you to save money on your energy prices.
  • It can make your home more comfortable to live in.
  • It can increase the value of your home.
  • It can help you to put your carbon footprint at a minimal level.
  • If you are thinking of selling or renting your property, you will need to obtain an EPC document.
  • Moreover, the EPC document encompasses:
  • A detailed breakdown of a property’s energy performance.
  • Insight into its environmental impact.
  • Recommendations for potential improvements.
  • An estimation of energy use coupled with potential savings.

FAQ

In the UK, special people called energy assessors check how well your home uses energy. They look at all sorts of things, like the type of house you have, how big it is, and how old it is. They also check how much energy you use to heat and light your home.

Energy assessors use a special system called SAM to check your home. SAM looks at all the factors that affect how much energy your home needs. These include the type of walls, windows, and doors you have, and whether you have any renewable energy sources like solar panels or wind turbines.

 Once the energy assessor has checked your home, they will give you an EPC certificate. This certificate tells you how efficient your home is at using energy. It also gives you tips on how to make your home more energy efficient.

Your EPC rating is valid for ten years. This means that you don’t need to get a new one unless you make major changes to your home, like changing the type of heating system you have.
