GREEN MATTERS
results of site sampling across a small but representative sample of transport industrial, cold store and commercial retail locations. The results of these investigations show that there is much more that system operators should be doing that would simply and cost eff ectively help them to improve system reliability as well as reducing emissions (which means reducing running costs for them). Findings of this site sampling work are being written up as sector specifi c guidance notes to be published later this year supported by webinars and training resources. Do follow the project website at
www.netzerorefrigeration.uk for the latest news and publications. Improving existing system operations is a good start to
reduce emissions, but when the time does come to replace or repurpose an existing system then reliable information on the effi ciency and emissions reduction opportunities of new technologies is also needed to help system operators to make the right long term investment decisions. The TICR project is currently working on an Innovation Matrix to give independent advice on the suitability of low carbon technologies or approaches to replacing or improving systems as their cooling needs change. Technologies will be ranked according to carbon savings opportunities they present, but also evaluated for ease of introduction and suitability for retrofi t. This will provide a useful guide for equipment owners to demystify some of the new technologies on the market and to help specifi ers or consultants with independent evaluations to refer to. The range of TICR project outcomes whether based on desk
research, questionnaires, industry meetings or site surveys are focusing in on three key elements of our carbon emissions reduction agenda:
Education and Skills Underpinning everything is having the right people and skills to achieve the best cooling solution. This encompasses the shortage of people particularly in design roles, lack of availability of training and qualifi cations, and lack of awareness of operators. Intelligent users are needed to ensure that intelligent solutions are put in place by knowledge designers and installers, and that they are kept operating to their very best capacity at all times.
Refrigerants Legislation will aff ect the choice of refrigerant available in future. Future legislation can be expected to further reduce direct emissions from leakage, restrict where higher GWP refrigerants can be used and put in place minimum standards for training or leak checking. As the industry moves towards much lower GWP refrigerants the importance of having a skilled workforce who know how to design, install, service and maintain the new technologies is only going to become more signifi cant for the green agenda.
Technologies As well as an increasing range of diff erent refrigerant solutions, new technology options need to be evaluated and eff ectively implemented or incentivised to achieve

potential energy savings. This will necessitate a closer working relationship between customer, specifi er consultant, designer and those responsible for installing, commissioning, maintaining and servicing. The TICR Technology matrix will help evaluate potential savings from new technologies, suitability of their application (eg new systems or retrofi t) by sector. This will assist end users in implementing appropriate procurement and investment strategies to achieve long-term solutions. The decisions of end users on type of systems they install today will have a long-term impact on their future emissions and running costs. Underpinning all of these fi ndings are the issues of accessing information and how that information is managed. This has been one of the most challenging aspects for the project team – fi nding the necessary data on which to base these guides and resources. This leads us to ask a critical question for our green agenda - how are end users going to know how well (or how badly) they are doing to reduce emissions unless they can measure the performance of their system against its design operation, it’s past operation and against the operation of similar systems elsewhere? The need for submetering, for analysis of operating parameters and for reviewing performance against design are going to be key elements for end users to get to grips with if they want to achieve effi cient and reliable refrigeration and for the sector to show that it can meet the challenge of net zero.
