Building Regulations Part L Review

We want your views on changes to Part L – the Conservation of Fuel and Power - of the Building Regulations and changes to the Approved Documents.
Start of consultation: 31/07/2012
End of consultation: 23/10/2012

The Building Regulations control certain types of building work and ensure that buildings meet certain standards of health, safety, welfare, convenience and sustainability.

In setting standards for building work the Building Regulations influence emission reductions in new buildings and existing buildings in Wales.  

We want to improve the energy performance of buildings in Wales through the Building Regulations. This will help Wales move towards zero carbon and near zero carbon energy buildings by 2020. Our proposals set out in this consultation are a significant step towards that objective.

This consultation contains proposals for:

  • Changes to Part L(Conservation of Fuel and Power) of the Building Regulations; 
  • Changes to the Approved Documents for Wales;
  • A new template for the Approved Documents for Wales; and
  • A discussion of future thinking as we move towards zero carbon.

The Approved Documents are guidance documents which set out some of the ways that the requirements in the Building Regulations can be met. The Approved Documents do not have to be followed, as long as the required level of performance can be shown to be achieved in a different way.

We will be working with Constructing Excellence to host consultation events throughout Wales.

The events will take place between 10:00 and 16.30 on:

  • 5 September – Cardiff;
  • 6 September – Carmarthen;
  • 12 September - Llandrindod Wells;
  • 13 September – Llandudno.

Software tools

We are making two free software tools available from 14 August 2012. They are called cSAPw (consultation Standard Assessment Procedure Wales), and cSBEMw (consultation Simplified Building Energy Model Wales).

These will allow you to work out the effects of proposed changes to:

  • the Regulations; 
  • Approved Document ADL1A and ADL2A; and 
  • the National Calculation Methodology (NCM).

These tools cannot be used to show compliance with Part L 2010 or to generate an Energy Performance Certificate (EPC).

The tool and user guide can be downloaded free from the Building Research Establishment (BRE) website.
