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.

室内空间的冷却是实现人们良好健康和福祉的基本手段，但也是与人类活动相关的能源最密集和污染最严重的过程之一。统计数据令人震惊；空调 (AC) 和电风扇约占当今世界各地建筑物总耗电量的 20%，每年排放超过 1.2 GT 的二氧化碳。同样，在热天，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转型，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 的总体目标是开发零能源输入、零排放（在使用）辐射冷却涂料/油漆，它还结合了商业、工业和住宅建筑的成本效益和低维护成本。通过适当的修改，该技术还将能够部署在汽车以及更广泛的运输行业。拟议的技术利用寒冷宇宙的无限热容量，将其本质上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 涂层将能够提供 >100 W/m2 的冷却功率，能够满足至少 30% 的典型住宅的冷却需求。该项目的主要目标是： i) 开发一个大型原型（>20 cm x 20 cm）。 ii) 在现场、不同地理位置和不同气候条件下对原型进行广泛的测试。 iii) 巩固强大的知识产权地位，iv) 制定商业化路线图，将 PolyCool 技术从实验室台式转化为市场。
