Approved Document L
ADL focuses on the reduction of carbon emissions. It has been divided into four sections:
- Part L1A – Conservation of fuel & power in new dwellings
- Part L1B – Conservation of fuel and power in existing dwellings
- Part L2A – Conservation of fuel and power in new buildings other than dwellings
- Part L2B – Conservation of fuel and power in existing buildings other than dwellings
ADL outlines performance targets for the building as a whole through the Target Carbon Emission Rating (TER), which takes into account heating, lighting and ventilation. In a nutshell, the impact on ventilation has been to “Build tight – Ventilate right”
The following key documents must be considered alongside Approved Document L:
- Standard Assessment Procedure
- Code For Sustainable Homes
- Home Information Packs
