GVF2012 Guide F: Energy Efficiency in Buildings

A Corrigendum to Guide F has been issued in August 2016 which is available to download here. This makes corrections to pages 20-10 and 11 to Tables 20.14 to 20.17. The Corrigendum has been incorporated in the revised pdf. Future purchasers of the hard copy will receive the Corrigendum with the book. 

Since the last edition of CIBSE Guide F, published in 2004, the UK Government has set a legally binding target to reduce national greenhouse gas emissions. The Government’s latest Carbon Plan sets out specific targets for improving the energy efficiency in new and existing buildings. There have also been significant regulatory changes over the last eight years, including two revisions to Part L of the Building Regulations and the transposition of the Energy Performance of Buildings Directive into UK legislation. The next two revisions of Part L will push for further improvements in energy efficiency to progress towards the Government’s aspiration for all new buildings to be zero carbon by 2019.

This 2012 edition of CIBSE Guide F includes a new section on ‘developing an energy strategy’. This reflects the changes to planning policy, which now include targets for reducing carbon dioxide emissions from new developments and the need to submit a detailed energy strategy report as part of the planning application.

Energy management has moved up the corporate agenda, aided by the work of the Carbon Trust and the implementation of the CRC Energy Efficiency Scheme. Part B of this Guide (covering the operation of the building) has been updated to include more information about carbon management, and the need for improved metering and monitoring.

In addition, the section on energy efficient refurbishment has been expanded in recognition of the pressing need to upgrade the existing building stock and the opportunities to improve performance.

This edition incorporates the new and revised guidance that has been published since 2004. This includes key CIBSE documents and publications by the Carbon Trust and BSRIA. These key references have informed many of the updates and are referenced throughout the Guide.

A new companion document to the Guide, titled Introduction to energy efficiency, is also avalable on the Knowledge Portal that introduces the main Guide and summarises the current policy agenda; the changing role of building services engineers, and the key themes of Guide F.
