Practical applications

of using vision-based systems in indoor environments, such as fast detection, propagation tracking, informing fi re fi ghters and combining detection with an HVAC system to allow controlled ventilation to aid in the decay of the fi re. The initial results presented here show the practicality of such an approach that could potentially be integrated with fi re fi ghting systems for various building spaces and environments. Project GreenSCIES, is a detailed design study to develop a Smart, Local Energy System (SLES) for a large community in the London Borough of Islington. Our consortium have developed an innovative SLES concept, centred around a fi fth generation district heating and cooling network. The GS ambient loop systems have negligible losses and much greater ef fi ciencies than traditional district heat networks. As recognised by the UK Government ’ s Heat and Buildings Strategy, ambient loop systems should be considered where large-scale neighbourhood regeneration occurs. The proposed SLES concept applied to wider urban areas could deliver signi fi cant carbon emission savings in the UK. This work investigates the cooling potential behind a practical project that involves recovering waste heat from the LU network. As electri fi cation leads to an increased deployment of heat pump and district heating systems, waste heat could become a valuable resource for maximising energy ef fi ciency, even more so when additional cooling bene fi ts can be achieved. This paper aims to explore the impacts of cooling on railway tunnels, emphasising how secondary bene fi ts, which are many times overlooked, could be critical to making waste heat recovery economically feasible, maximising its potential as a key technology for decarbonising heat. These research results can be used as a reference for selection of the installation position of the outdoor unit and blade angle of the louvre in the practical engineering application when single and double outdoor units are installed in a recess, which is of great signi fi cance in improving the EER of air conditioners and saving energy. Good understanding of occupant comfort is necessary to reduce building energy consumption without compromising comfort. This article explores the use of ASHRAE Comfort Database II for determining occupant comfort in MM buildings in temperate oceanic climates and the limitations faced therein. A practical and publicly accessible database developed based on the recommendations from this study will improve thermal comfort models and enable better prediction of occupant comfort while improving energy ef fi ciency substantially.
