Cooling of indoor spaces is a fundamental means to attain peoples' Good Health and Well Being, yet is one of the most energy intensive and highly polluting processes associated with human activity. The statistics are staggering; air-conditioners (AC) and electric fans account for ~20% of the total electricity consumed in buildings around the world today and contribute over 1.2 GT of CO2 emissions per year. Likewise, AC may be responsible for 40% of an electric vehicle's battery usage on a hot day. To combat climate change and accelerate the transition towards carbon neutral economies, paramount targets of EU's Green Deal, energy efficient and sustainable indoor space and vehicle cooling technologies are imminently required.PolyCool's overarching objective is to develop zero-energy input, zero-emissions (during usage) radiative cooling coatings/paints, which also combine cost efficacy and low-maintenance for commercial, industrial and residential buildings. With proper modifications, the technology will also be able to be deployed in the automotive and more broadly in the transportation industry as well. The proposed technology is leveraging the infinite heat capacity of the cold Universe, converting it in essence into an inexhaustible heatsink for the thermal radiation emitted by the built environment and vehicles on Earth. Crucially, it is completely passive and does not require electric pumps, fans or coolers to operate. PolyCool coatings will be able to provide a cooling power of >100 W/m2, able to cover at minimum 30% of a typical residency's cooling needs. The key objectives of this project are; i) Develop a large -scale prototype (>20 cm x 20 cm). ii) Perform extensive testing of the prototype in the field, in various geographical locations and under various climatic conditions. iii) Consolidate a strong intellectual property position and, iv) develop a commercialisation roadmap to translate PolyCool technology from the lab benchtop to the market.

为室内空间降温是实现人们良好健康和幸福的基本手段，但也是与人类活动相关的最耗能、污染最严重的过程之一。统计数字令人震惊；空调（AC）和电风扇占当今世界建筑物总用电量的20%左右，每年排放的二氧化碳超过12亿吨。同样，在炎热的天气里，交流电可能占电动汽车电池使用量的40%。为了应对气候变化并加速向碳中和经济的过渡，迫切需要欧盟绿色协议的首要目标，节能和可持续的室内空间和车辆冷却技术。PolyCool的首要目标是开发零能源投入，零排放（在使用过程中）辐射冷却涂料/油漆，同时结合成本效益和低维护成本，适用于商业，工业和住宅建筑。经过适当的改进，这项技术也将能够应用于汽车领域，并在运输行业得到更广泛的应用。拟议中的技术是利用寒冷宇宙的无限热容量，将其转化为取之不尽的散热器，用于地球上建筑环境和车辆发出的热辐射。至关重要的是，它是完全被动的，不需要电动泵、风扇或冷却器来运行。PolyCool涂料将能够提供100瓦/平方米的冷却功率，能够满足至少30%的典型住宅的冷却需求。本项目的主要目标是：i)开发大型原型（>20 cm x 20 cm）。ii)在实地、不同地理位置和不同气候条件下对原型进行广泛测试。iii)巩固强大的知识产权地位；iv)制定商业化路线图，将PolyCool的技术从实验室台式转化为市场。
