Proposal for building regs Part Z launched

Building Regulations Part Z
Around 150 construction bodies support the proposals

A group of over 150 organisations in the UK building industry, including the Chartered Institute of Building (CIOB), has put forward a plan for a new element for the building regulations, called Part Z.

The new element would incorporate requirements for the assessment of whole life carbon emissions for all major building projects.

Five construction professionals have written a report proposing Part Z. They are:

Among the organisations supporting the proposal are: CIOB, ICE, CIBSE, the Institution of Structural Engineers (IStructE), the Royal Institute of Architects (RIBA), the Royal Town Planning Institute (RTPI), the Steel Construction Institute (SCI), the Structural Timber Association (STA), UK Green Building Council (UKGBC), Off-site Homes Alliance (OSHA), and Construction Industry Council (CIC).

Caroline Gumble, CEO of CIOB, said: “Sustainability and the push to achieve net zero have, quite rightly, taken their place as priorities in construction. CIOB is supportive of regulatory moves to enable a focus on embodied carbon, not just operational carbon emissions, and add weight to its consideration as part of the construction and development process.

"Sustainability is already something which informs much of our work – and will for years to come – and we have been clear to our members that opportunities to take a more environment-centred approach, combined with practical measures and clarity in legislative requirements, should be welcomed.

"The industry needs to walk the walk on minimising climate change, not just talk the talk, and we expect CIOB members to update their knowledge through CPD and understand how they can make a meaningful positive contribution to achieving net zero.”

  1. Adds no value.
    Has no provable outcome.
    Adds construction cost.
    Build less and administer more.

    It’s a build tax
