Domestic building services compliance guide
The Domestic Building Services Compliance Guide is a government publication that provides guidance on the installation of building services in new and existing properties to assist in complying with the energy efficiency requirements of the Building Regulations.
It provides more detailed information on the guidance contained in Approved Document L1A: Conservation of fuel and power in new dwellings, and Approved Document L1B: Conservation of fuel and power in existing dwellings.
The most recent version of the guide was published in 2013 and came into effect in April 2014. The guide is concerned with the installation of:
- Space heating.
- Domestic hot water.
- Mechanical ventilation.
- Comfort cooling.
- Internal and external lighting.
- Low-carbon heat generation through the use of heat pumps, solar thermal panels and micro-combined heat and power units.
It sets out recommended minimum energy efficiency standards for components of building services systems, including controls. For systems installed in new buildings, the standards are design limits. For new or replacement systems and components installed in existing buildings, the standards represent reasonable provision for complying with the building regulations.
It also provides supplementary information regarding good practice that exceeds the minimum standards, such as Microgeneration Certification Scheme standards.
The guide is broken down into four fuel-based sections and nine technology-specific sections:
- Section 2 Gas-fired space and water heating.
- Section 3 Oil-fired space and water heating.
- Section 4 Electric heating.
- Section 5 Solid fuel heating.
- Section 6 Community heating.
- Section 7 Underfloor heating.
- Section 8 Mechanical ventilation.
- Section 9 Heat pumps.
- Section 10 Comfort cooling.
- Section 11 Solar water heating.
- Section 12 Lighting.
- Section 13 Micro-combined heat and power.
- Section 14 Heating system circulators.
- The Ecodesign Directive 2009/125/EC which provides a background for establishing the requirements for ‘energy related’ products.
- Energy Labelling Directive 2010/30/EU – This provides a system for labelling energy-related products such as lamps and washing machines.
- Renewable Energy Directive 2009/28/EC – This promotes the use of energy from renewable sources.
- Energy Efficiency Directive 2012/27/EU – This encourages energy efficiency to ensure the EU meets its commitment to achieve a 20% energy consumption reduction by 2020.
- Energy Performance of Buildings Directive 2013/31/EU – This directive sets out minimum energy performance standards and the methods for calculating the performance of buildings, as well as inspections of heating and air conditioning units.
