NET ZERO SYSTEMS & SOLUTIONS


London regeneration project on course for Net Zero


Kingspan Kooltherm Pipe Insulation has been fi tted as part of Phase 4 of the North West Quarter regeneration project in South Kilburn. The 225-home development is being delivered by Countryside Partnerships and the London Borough of Brent. To meet planning requirements, the development needed to achieve Net Zero carbon emissions (as defi ned within the London Plan) and eff ectively limit overheating risk. The specifi cation of Kooltherm Pipe Insulation helped meet these requirements.


T


he development has been designed by Pollard Thomas Edwards and incorporates 95 council homes along with a further 130 homes for


private buyers. Its design takes inspiration from surrounding Victorian mansion fl ats, and care has been taken to support occupant wellbeing with virtually all of the spacious homes featuring dual aspect windows.


As part of the major redevelopment plan, the


project needed to meet the requirements within the London Plan for it to be “net zero carbon”. This required it to achieve a minimum 35% additional on-site reduction in CO2 emissions compared with a property built to Part L 2021 of the Building Regulations, with any remaining demand covered through carbon off set. A range of measures have been implemented to help achieve this, including connecting the development to the South Kilburn District Heat Network. To limit heat losses from secondary pipework, the pipe insulation was fi tted on low temperature hot water (LTHW) and boosted cold water service (BCWS) pipework by Ace Thermal.


The pipe insulation solution achieves a 25-year aged thermal conductivity as low as 0.025 W/mK (at 10 °C mean), making it one of the most thermally effi cient insulation materials commonly used for insulating pipework. This performance made it possible for Ace Thermal to insulate all internal pipework to a high standard with a thinner thickness of insulation than would have been possible with lower performing alternatives, supporting ease of installation within service spaces.


“The pipe insulation solution achieves a 25-year aged thermal conductivity as low as 0.025 W/mK (at 10 °C mean), making it one of the most thermally effi cient insulation materials commonly used for insulating pipework.”


Scott Bunyard, director at Ace Thermal Insulation, commented: “Our team has completed all installations to programme working with the client. Kooltherm provided a straightforward solution to meeting the heat loss requirements across all of the LTHW and BCWS systems. Our work has also included fi tting made-to-measure jackets on all risers throughout and insulating the substation and tank rooms in thicknesses up to 65 mm to further minimise heat losses.” In addition to supporting the project in meeting its Net Zero carbon commitments, the specifi cation


of Kooltherm Pipe Insulation was also important for limiting overheating risk. As part of the planning process, an analysis was carried out to CIBSE TM 59 assessment criteria to ensure that no corridors exceeded an operative temperature of 28°C for more than 3% of the total annual hours in a year. Limiting heat losses from pipework within these areas was critical to passing this requirement. The overheating analysis showed that with the specifi ed thickness of the pipe insulation, all of the modelled corridors passed the requirements. To support specifi cations, Kooltherm Pipe Insulation is available as a freely downloadable BIM fi le from NBS Source and an Environmental Product Declaration (EPD) certifi cate can be downloaded from the Kingspan website. To help project teams understand the impact of pipe insulation specifi cations on operating costs and carbon emissions, Kingspan Technical Insulation also off ers the Pipe Insulation Carbon Calculator. This free service allows specifi ers to compare how the use of pipe insulation specifi cations to key standards, including BS 5422 enhanced thicknesses and CIBSE CP1, can impact operational emissions and costs.
