Display Energy Certificates
The Law
The EU introduced the Energy Performance of Buildings Directive (EPBD) in 2002. The UK Government followed with the Energy Performance of Buildings (Certificates and Inspections) Regulations in 2007. Commercial and public sector buildings contribute over 20% of the UK's carbon footprint. The introduction of Display Energy Certificates (DECs) for public buildings is part of a series of legislation to dramatically improve the energy efficiency of the UK's building stock, both new and existing.
Display Energy Certificates: What is it?
A DEC shows the energy performance of a building based on actual energy consumption. The rating is an indicator of the annual CO2 emissions caused from operating the building. This rating is shown on a scale from A to G, where A is the lowest CO2 emissions (best) and G is the highest CO2 emissions (worst). Also shown on the certificate are the ratings for the previous two years; this provides information on whether the energy performance of the building is improving or not. The rating is based on the amount of energy consumed over a period of 12 months and is taken from meter readings.
Understanding Display Energy Certificates (DECs) in the UK
Maintaining Up-to-Date Data:
- Yearly Updates: DECs require annual updates reflecting the building’s energy consumption over the past 12 months.
- Advisory Report: The initial DEC comes with a valid Advisory Report (valid for seven years) containing recommendations for improved energy performance (e.g., building upgrades, maintenance).
Who’s Responsible?
- Occupier’s Duty: Public authorities and institutions occupying buildings exceeding 1,000 sqm gross internal floor area (GIA) are legally responsible for DEC compliance.
- Public Display: A valid DEC must be prominently displayed for public visibility.
DECs vs. EPCs: Key Differences
- Widely Used EPCs: Energy Performance Certificates (EPCs) are prevalent, existing for nearly 20% of UK buildings.
- Notional vs. Actual Performance: EPCs provide a theoretical energy rating assuming proper operation. DECs reflect real-world energy use based on actual data.
- Year-on-Year Efficiency Tracking: DECs are considered a more effective tool for monitoring and improving annual energy efficiency.
- Cross-referencing: If a building has an EPC, it must be referenced on the DEC.
Public Access and Transparency:
- Government Database: The UK government maintains a public database where all DECs are readily accessible for everyone.
- Promoting Efficiency: Public access aims to encourage building occupiers to prioritize energy efficiency measures.
Producing a DEC:
- Qualified Assessors: Only accredited and independent Energy Assessors can create DECs and Advisory Reports.
- Process and Quality Assurance: Energy Assessors conduct energy assessments, produce DECs and reports, and submit them to the government database. Their accreditation ensures accuracy and proper production.
Consequences of Non-Compliance:
- Financial Penalties: Failing to display a DEC or having an outdated Advisory Report can result in fines of £500 and £1,000 respectively, repeated every 28 days of non-compliance.
- Reputational Damage: Organizations risk negative publicity for environmental regulation breaches.
By understanding these key points, public building occupiers can ensure they meet DEC requirements, promote energy efficiency, and contribute to a greener future.
