Display Energy Certificate (DEC)
(DEC)
Display Energy Certificate
A Display Energy Certificate (DEC) is an official document that provides information about the energy efficiency of a public building. It is mandatory for public buildings in the UK that have a total useful floor area over 250 square meters and are frequently visited by the public. DECs display an energy rating on a scale from A to G, with A being the most energy-efficient and G being the least energy-efficient. The certificate also includes recommendations for improving energy performance and reducing carbon emissions.

Importance of Display Energy Certificates for Public Buildings
Energy Efficiency
DECs play a crucial role in promoting energy efficiency in public buildings. By assessing and displaying the energy performance of a building, DECs raise awareness among building occupants and stakeholders, encouraging them to adopt energy-saving measures and reduce energy consumption. This helps to lower operating costs and minimize the environmental impact of public buildings.
Sustainability
Public buildings have a significant impact on the environment due to their size and energy consumption. DECs promote sustainability by encouraging building owners and managers to implement energy-saving strategies, invest in renewable energy sources, and adopt sustainable practices. By improving energy efficiency and reducing carbon emissions, public buildings contribute to a greener and more sustainable future.
Public Transparency
DECs promote transparency by providing easily understandable information about the energy performance of public buildings. This allows the public to make informed decisions when choosing public facilities based on their energy efficiency and environmental impact. It also encourages building owners and managers to strive for better energy performance to enhance their reputation and attract environmentally conscious individuals and organizations.
Compliance with Regulations
Display Energy Certificates are a legal requirement for public buildings in the UK. Compliance with these regulations ensures that public buildings meet minimum energy performance standards and contribute to the government’s energy-saving targets. Failure to obtain or display a valid DEC can result in penalties and reputational damage. By obtaining a DEC and implementing the recommended energy-saving measures, building owners and managers demonstrate their commitment to legal compliance and sustainable practices.

The Display Energy Certificate Process
Assessment:
To obtain a Display Energy Certificate, a qualified energy assessor visits the public building to collect data related to energy consumption, building occupancy, and other relevant factors. They may also request utility bills and other documentation to verify energy usage.
Energy Performance Calculation:
Using the collected data, the energy assessor calculates the energy performance of the building and assigns an energy rating on a scale from A to G. The rating is based on the actual energy consumption per square meter of the building’s useful floor area.

The Display Energy Certificate Process
Recommendations:
The Display Energy Certificate includes recommendations for improving energy performance and reducing carbon emissions. These recommendations are tailored to the specific building and may include actions such as upgrading insulation, optimising heating, and cooling systems, or installing energy-efficient lighting.
Display and Renewal:
The Display Energy Certificate must be prominently displayed in a visible location within the building, such as the main entrance or reception area. DECs are valid for one year for buildings over 1000 Sq.m and 10 years for building with floor area of 251-1000 Sq.m and must be renewed annually to ensure up-to-date information about the building’s energy performance.

Improving Energy Performance
Building owners and managers can take several steps to improve the energy performance of public buildings:
Energy Monitoring and Management
Implement an energy monitoring system to track energy consumption and identify areas of high usage. Establish energy management practices to optimize energy efficiency and reduce wastage.
Energy-Saving Measures
Implement energy-saving measures recommended in the Display Energy Certificate, such as upgrading insulation, installing energy-efficient lighting, or improving HVAC systems. Consider investing in renewable energy sources like solar panels or geothermal systems.
Occupant Engagement
Educate building occupants about energy-saving practices and encourage their participation. Promote behaviour changes, such as turning off lights and equipment when not in use and encourage energy-conscious habits.
Regular Maintenance
Conduct regular maintenance of building systems and equipment to ensure optimal energy efficiency. Inspect and repair any leaks, malfunctions, or inefficiencies promptly.
Display Energy Certificates are essential for public buildings, providing information about energy performance, promoting energy efficiency, and contributing to sustainability. By obtaining and displaying a valid DEC, public buildings can demonstrate their commitment to energy efficiency, comply with regulations, and improve their environmental impact. Implementing the recommended energy-saving measures not only reduces operating costs but also helps create a greener and more sustainable future.
