SPECIAL FEATURES INDUSTRIAL AND COMMERCIAL HEATING AND COOLING This month: CP1 Heat networks: Code of Practice, the future for refrigerants and pre-commission cleaning 10 MAJOR CHANGES TO CP1 (2020) A big update to the CP1 (2020) Heat networks: Code of Practice aims to improve performance and provide the foundations for a quality assurance scheme. The authors, Phil Jones, Paul Woods and Martin Crane, highlight the key changes C P1 (2020) Heat networks: Code of Practice is a major update to the 2015 version, and a huge step forward for the industry. Developing this edition of the Code, published by CIBSE and The Association for Decentralised Energy (ADE), has involved a vast amount of consultation. Gaining widespread consensus, it has helped to define the heat networks sector as a maturing growth area that can make a significant contribution to decarbonising heat across the UK. More than 50 experts came together to agree the Code. Three major rounds of consultations including one public round gave rise to contributions and comments from around 100 others, generating 3,000 comments. Its been an epic journey, but the industry is much the better for it, with everyone on the same page. CP1 (2015) proved to be a catalyst for major change in the industry; it is doubtful that we would have been able to drive the sort of success we have had without it. Today, we have a much greater number of highperformance schemes, which are largely a product of the CP1 (2015) initiative. It was always recognised, however, that the Code of Practice would need to be updated at intervals, to reflect new experience and understanding, feedback from the industry, changes in regulation, and results from research projects. So, what are the key changes in CP1 (2020)? To give you a flavour, here are 10 of the most significant ones. 1. Customer satisfaction A new theme in the Code is additional focus on providing customers with affordable heat and a reliable service. Customer satisfaction starts at the briefing stage and runs through all stages of CP1. We need to make sure the end-user is happy with the service. If they are not, we have failed. CP1 is now complementary to the Heat Trust (the non-profit organisation that sets standards on customer protection) and sets early commitments and eventual requirements to sign up to Heat Trust for all heat networks. The 240-page Code is almost threetimes larger than the previous version www.cibsejournal.com February 2021 33 CIBSE Feb21 pp33-34, 36-37 CP1 Heat Newtork Code.indd 33 22/01/2021 17:52
