Energy performance certificates (EPC) and green deal assessments (GDA)

Energy performance certificates (EPC) and green deal assessments (GDA)The Green Deal helps you make energy-saving improvements to your home and find the best way to pay for them.

 

What are they?

The Green Deal helps you make energy-saving improvements to your home and find the best way to pay for themEnergy Performance Certificates (EPCs) are the output from a Domestic Energy Assessment (DEA). A DEA analyses the energy consumption and CO2 emissions of a property based on typical occupancy and usage to enable it to be compared with the total UK housing stock with regard to energy efficiency and environmental impact. This produces a performance rating from A (very efficient) to G (poor). Producing an EPC involves conducting a survey of your home to collect data relevant to energy usage such as: dimensions, building construction type and age, heating and hot water systems, levels of insulation, and lighting. This data is fed into standard software to generate the EPC report.

Why do I need one?

Daikin Packaged Hot Water CylinderIf you install Solar PV and wish to claim the Government’s Feed-In Tariffs (FITs) then you will need to have an EPC in place that shows your house is Band D or better to enable you to claim the highest tariff. An EPC is valid for 10 years from issue.

If you install a renewable heating system in your home and wish to claim the domestic Renewable Heat Incentive (RHI) then you need to have the following surveys in place when you apply:

  • an EPC that has been produced after 1 April 2012 (in England and Wales) or after 1 October 2012 (in Scotland) and that at the point of conducting the survey there have been no changes to the property since the EPC was lodged that would materially affect its outcome.
  • The EPC must not include any recommendation for cavity wall insulation or loft insulation. If it does then these actions need to be addressed and another EPC obtained to demonstrate that they have been cleared.
  • A Green Deal Occupancy Assessment (OA) based on an EPC that was valid at the time the OA was conducted.

Bright Green Renewables has staff trained and certified to conduct these surveys and to lodge EPCs and OAs.

Energy Audits for Businesses

Are you confident that you are using your energy as efficiently as possible?

Do you want to save money by developing and implementing a plan to reduce your energy consumption?

You could make savings through zero-cost behaviour changes or investment in new technologies with payback periods of two years or less.

Bright Green Renewables can help you to identify and implement energy saving behaviours and solutions, initially through an energy audit.

A typical audit format is as follows:

  • Agree scope and duration of audit.
  • Visit client facilities at an appropriate date.
  • Receive energy usage data, ideally for at least 3 years (copies of energy bills would be acceptable).
  • Interview appropriate staff to understand the organisation's objectives for energy saving, the facilities, usage profiles, energy sources, controls, building construction, behaviour etc.
  • Conduct a tour of the facilities to observe and measure key elements.
  • Research potential solutions for energy saving and on-site generation.
  • Identify opportunities for Government grants and incentives (FITs, RHI).
  • Prepare a report of opportunities with estimated costs, benefits and payback where possible.
  • Send the report to appropriate staff and arrange a review either face to face or by phone as desired by the client.

This process can be extended to include follow-up audits, support to implement energy-saving and renewable energy generation opportunities, guidance to implement additional utility monitoring systems (such as continuous monitoring and sub-metering), and ongoing analysis of energy consumption data.
