Collaborating for success
As Nottinghamshire Police embarked on a series of heating refurbishments across its stations, early collaboration between the project team was critical to achieve all the project and site requirements, as Paul Arnold, product manager for Remeha, explains
reduce wasteful energy consumption and associated emissions. Given that some 80% of the UK’s existing building stock will still be in use in 2050, reducing emissions from these buildings is essential to meet our new, ambitious net zero carbon target. Heating is one of the largest users of

energy in a building, making it a natural starting point for improvement. With many non-domestic buildings relying on boilers for heat, replacing any ageing or inefficient boilers with more energy-efficient models is one of the most practical, cost-effective means of improving a building’s energy performance. So when, during a standard condition
survey, consultants CJR Midlands found severe failings in most of the old existing plant at Nottinghamshire Police’s sites, the force was quick to act. Reliability and high energy efficiency
were the key concerns to reduce its environmental impact and improve comfort levels and staff wellbeing within the stations. The Police also needed to be able to monitor energy usage live across the sites from the main headquarters. The critical challenge was the tight schedule, as all seven sites – including two new Liquefied Petroleum Gas (LPG) compounds - needed to be fully completed within just three months. Additionally, all police stations had to remain open during the works. This meant ensuring that there was zero interruption to the hot water service throughout the project, and that the heating systems were all fully operational by the start of the new heating system. To achieve the requirements for
improved reliability and efficiency, CJR Midlands recommended refurbishing the seven plant rooms with new energy-

efficient condensing boilers together with associated pumps and vertical flue masts. New Building Management System (BMS) controls were also specified to enable CJR to monitor all the sites from Sherwood Lodge, the main police headquarters. Remeha was selected to provide boilers
throughout the scheme. David Griffiths, regional director at CJR Midlands, explained: “Working within such a narrow timeframe, it was essential to select a proven manufacturer – so we chose Remeha. They have consistently provided us with excellent service and support, including assisting with surveys. The good availability of spare parts was also key.” At Radford Road police station, two

requirements. At the remainder of the sites, including the Sherwood Lodge headquarters, a combination of Gas 220 Ace boilers was selected to match the individual heat output demand. Remeha’s ability to offer offsite
fabricated cascade arrangements for its ultra-compact Gas 220 Ace floor-standing range was a major advantage on this extensive refurbishment programme. Most projects will benefit from early engagement between consulting engineers, contractors and manufacturers to help ensure a smooth installation and successful outcome. However to achieve all the project and site requirements for Nottinghamshire Police, a truly collaborative working relationship was required between CJR Midlands, ABSN, the appointed M&E contractors for main contractors GF Tomlinson, and Remeha, the heating manufacturer. Using prefabrication enabled full
collaborative engagement from the team from the outset, so that any physical fit issues could be identified and rectified early on in the design process. The ability to achieve the physical design
of the cascade system ahead of delivery was a key specialist contribution that helped to ensure successful project delivery. By front-loading the design effort, all aspects could be considered and factored in before any build took place. This resulted in important time savings, keeping the project on schedule.
