Energy Star is an internationally recognised certification programme that identifies and promotes energy-efficient products, buildings, and practices. In the UK, it is often referenced in the context of energy-efficient appliances, heating systems, and building materials. While the Energy Star programme is primarily associated with the United States, its principles align with UK Building Regulations and energy efficiency standards, such as those outlined in Approved Document L (Conservation of Fuel and Power).
Energy Star certification ensures that products or systems meet strict energy efficiency criteria set by environmental standards. For example, an Energy Star-rated boiler or refrigerator consumes significantly less energy than non-certified models, reducing both energy bills and carbon emissions. In the UK, this aligns with the government’s Net Zero Strategy and the Future Homes Standard, which aim to improve the energy performance of new and existing buildings.
Synonym(s): Energy Efficiency Label, Energy Performance Certification
Practical Examples:
- Residential Retrofit: Homeowners replacing an old boiler with an Energy Star-certified model can achieve up to 15% energy savings, complying with Part L of the Building Regulations.
- New Builds: Developers installing Energy Star-rated windows in a housing project can enhance thermal performance, meeting the U-value requirements of Approved Document L.
- Renovations: During a kitchen renovation, opting for Energy Star-rated appliances ensures compliance with energy efficiency standards while reducing long-term operational costs.
Related Terms:
- U-Value: A measure of heat loss through a building element, such as walls or windows, expressed in W/m²K. Lower U-values indicate better insulation.
- SAP Rating (Standard Assessment Procedure): The UK’s methodology for assessing and comparing the energy and environmental performance of dwellings.
- EPC (Energy Performance Certificate): A document that rates the energy efficiency of a property on a scale from A (most efficient) to G (least efficient).
- Part L (Building Regulations): The section of UK Building Regulations that focuses on the conservation of fuel and power in buildings.
- Net Zero Strategy: The UK government’s plan to achieve net-zero carbon emissions by 2050, influencing building design and energy use.
