EWS IN BRIEF Climate action plan to be revealed at COP26 A cross-industry climate action plan is to be presented at COP26 by construction institutions. Carbon Zero will be presented during Built Environment Day at COP26, on 11 November. CIBSE is one of the signatories and has had an influential role in determining the actions. The actions we have committed to in this plan are substantial, and range from a review of accredited degrees and CPD requirements through to joint industry targets, guidance and associated professional obligations, said Julie Godefroy, head of sustainability at CIBSE. Signatories have committed to publish an implementation plan by COP26. See page 16 for more. Architects and engineers they add. More than 100 architects, engineers and other building professionals have produced a under the banner of the London Energy Transformation Initiative (LETI). and gives practical advice on how to transform and heat pumps, in line with carbon-reduction four primary housing types: mid-terrace, semidetached, detached, and apartment. The authors say that more than one million Embodied energy in heating revealed Embodied energy in heating and hot water systems is responsible for between 3% and 25% of whole-life embodied carbon in a building, according to new research for CIBSE. The study, undertaken by Elementa Consulting revealed an average measure of 9kgCO2e per kg of product weight in the systems examined. Products were selected to represent the most used heating and hot-water systems in newbuild residential schemes in the UK. The results will be published in new CIBSE guidance TM65.1. Manufactures are invited to take part in a new study on offices. See page 28 for more information. Greener London projects to get faster approval London Mayor Sadiq Khan has published guidance designed to ensure new developments are greener by giving faster approval if they prioritise energy performance and give more space for walkers, cyclists, and public transport users. The guidance will require developers to monitor and report the operational energy performance of major developments for at least five years post-construction, which the mayor sees as a critical step towards his strategy for delivering net zero carbon buildings. use requirements, and aims for a 60-80% reduction in total energy consumption for the average UK home. These targets have been determined through a combination of measures are realistically achievable, informed issues such as renewable energy provision and knowledge and understanding of how to make disseminated across the construction industry so that these requirements become standard CO2 emissions rebound after lockdown CO2 emissions have risen sharply since global economies got back up and running, according to the latest analysis from the International Energy Agency (IEA). , which increases the need for governments to invest $4tn in climate-mitigation measures before the end of this in fossil-fuel use, with demand beginning to reach pre-pandemic levels as lockdown restrictions lift concerted action is needed from governments. incumbency of fossil fuels in our energy systems. Governments need to resolve this at COP26 by giving a clear and unmistakeable signal that they are committed to rapidly scaling up the clean and resilient 6 November 2021 www.cibsejournal.com CIBSE Nov21 pp06-07 News.indd 6 22/10/2021 18:09
