The primacy of developing and accelerating the delivery of Net Zero solutions in Africa is underscored by the alarming impact of climate change in countries such as Kenya. In addition to temperature rises, increased floods, droughts and storms have dealt harsh socio-economic consequences in both urban and rural areas. Whilst Africa's 4% contribution to global warming(1.45 billion tonnes) is low in comparison to other nations, the existing warm-climate means that it is poorly suited to cope with the consequences of climate change, already experiencing intense fallouts of environmentally damaging carbon emissions.To temper the effects of climate change by supporting Africa to transition to Net Zero solutions, the development of innovative passive technology is necessitated. This project targets the cooling industry, traditionally dominated by AC usage, responsible for approximately a quarter of Kenya's GHG emissions. In alignment with the Kenyan Government's plans to cut carbon emissions by 32% by 2030\. and the National Action Cooling Plan, focus is on the development and expansion of a passive air-cooling technology that can entirely replace, or significantly reduce, the rising demand (in response to temperature increases) for energy-intensive air-conditioning. FREECOOL+ is based on patented technology, first developed under an Energy Catalyst Grant and trialled in north-west Kenya. The system, which has been specifically designed as a lower-cost alternative to the parent product (FREECOOL), to meet the needs of the African market, entails a roof mounted wind tower, heat pipes and a cold sink to continually cool the incoming air, providing fresh air supply and cool environments by up to 15 °C.This project will further the development, testing and demonstration of FREECOOL+ to accelerate uptake and widespread roll-out, particularly focussed on night-time cooling. The system will be trialled in a variety of real-world settings (including accommodation blocks/offices/healthcare facilities) in both urban and rural areas. Independent verification from the BRE indicated that FREECOOL+ has capability to achieve sufficient air-cooling at night-time, without support from any mechanical ventilation. Furthermore, working in tandem with AC units, FREECOOL+ can dramatically reduce power-demands, lowering carbon emissions and mitigating pressure on over-stretched power-grids.This is a high-impact, disruptive technology proposal, that presents a viable conduit to cut/lowering Kenya's carbon emissions; appealing to African markets as a low-cost, effective solution.Project leaders will be Free Running Buildings, an SME with extensive experience and expertise in passive ventilation technology, in partnership with the University of Sheffield and Enso Ventures in Kenya.

气候变化对肯尼亚等国家造成的令人震惊的影响凸显了在非洲制定和加速实施净零解决方案的重要性。除了气温上升之外，洪水、干旱和风暴的增加也给这两个国家带来了严重的社会经济后果。虽然非洲对全球变暖的贡献为4%（14.5亿吨），但与其他国家相比较低，但现有的温暖气候意味着它不适合应对气候变化的后果，已经经历了严重的气候变化。为了通过支持非洲向净零解决方案过渡来减轻气候变化的影响，需要开发创新的被动技术，该项目针对传统上以空调使用为主的冷却行业，该行业负责大约根据肯尼亚政府到 2030 年将碳排放量减少 32% 的计划和国家行动冷却计划，重点是开发和扩展完全可以减少碳排放的被动空气冷却技术。 FREECOOL+ 是根据能源催化剂补助金首次开发并在肯尼亚西北部进行试验的专利技术，以取代或显着减少对能源密集型空调不断增长的需求。专为母产品 (FREECOOL) 的低成本替代品而设计，以满足非洲市场的需求，需要安装在屋顶的风塔、热管和冷水槽，以持续冷却进入的空气，提供新鲜空气供应和使环境温度降低高达 15°C。该项目将进一步开发、测试和演示 FREECOOL+，以加速采用和广泛推广，特别关注夜间冷却。该系统将在各种现实世界中进行试验。 BRE 的独立验证表明，FREECOOL+ 能够在夜间实现充分的空气冷却，无需任何机械通风的支持。与交流机组配合使用，FREECOOL+ 可以显着减少电力需求，降低碳排放并减轻电网过度紧张的压力。这是一项具有高影响力、颠覆性的技术提案，为削减/降低肯尼亚碳排放提供了可行的途径作为一种低成本、有效的解决方案，吸引非洲市场。项目领导者将是 Free Running Buildings，这是一家在被动通风技术方面拥有丰富经验和专业知识的中小企业，与谢菲尔德大学和 Enso 合作在肯尼亚创业。
