Building Regulations in Energy Efficiency: What You Need To Know
When it comes to energy efficiency and sustainability, there are a number of building regulations and certifications that builders are expected to adhere to. These set of minimum standards have become more specific and stringent as more people recognise the economic impact of non-renewable energy resources and their effects on the environment. Here are some examples.
Building Regulations Part L
Part L of the Building Regulations is a government-approved document that particularly ensures the conservation of fuel and power. L1A relates to new dwellings while L1B is for existing dwellings. This involves design guidelines and provisions on:
- Limiting heat gains and losses through thermal-efficient elements and circulation pipes
- Restricting solar gains during the summer season
- Minimising carbon emission rate, which must not go beyond the Target Emission Rate (TER).
- Fabric energy efficiency rate calculations
- Air permeability and pressure testing
- Commissioning of heating and hot water systems
- Adapting energy-efficient technologies in operations
The Energy Performance Certificate (EPC)
The Energy Performance of Buildings (England and Wales) Regulations 2012 specifies that energy performance certificates should be secured or retrieved for buildings and dwellings that are built, sold, or let, including those that have roof and walls and rely on energy to maintain a conducive indoor climate.
For new builds, the person or organisation carrying out the work should provide an energy performance certificate to the property owner and a notice to the building control body that a number has been registered.
To obtain an EPC, an energy assessor or a person accredited to conduct an Energy Performance Report or a SAP calculation will visit for a survey and evaluate your property based on existing energy regulations. They will then provide an energy performance rating and suggest recommendations on steps you can take to improve your score.
