Envirosurface - Urban Heat Management Eco Paving (High Albedo Index PU-R Composite)

超过55%的世界人口生活在城市地区，预计到2050年将增加到68%（联合国）。城市化基础设施的相应增长造成了热污染的增加，称为城市热岛效应（UHI）。这些热污染物造成了复杂的空气质量问题，如地面臭氧（烟雾）和酸雨的形成，以及对当地植物群、动物群和水体的负面影响。空调用电需求增加，温室气体排放增加，导致全球气候变化。一个拥有100万人口的城市的年平均气温比周围地区高1-3°C，夜间可高出12°C。城市热岛效应导致人们的热不适，由于增加的全身不适，疲惫，与热有关的死亡率，呼吸问题和中暑，公共卫生恶化。（铺路专家）与伍尔弗汉普顿大学合作（材料科学和工程专家）正在开发Envirosurface，这是一种创新的反射铺装表面，具有更高的紫外线/红外线反射水平和更高的反射指数，因此，吸收太阳能少，减少热污染。除了减少表面的UHI特性，它将由回收材料组成，耐用，磨损和氧化的恶化有限，并且由于其高度的结构完整性，需要更少的维护。减少UHI将减少商业企业和居民空调的电费，并将对人们的健康产生积极影响，减少与热相关的死亡和不适。

Over 55% of the world's population lives in urban areas, with an estimated increase to 68% by 2050 (UN). The corresponding growth in urbanisation infrastructure has created increased heat pollution, referred to as the Urban-Heat-Island effect (UHI). These heat pollutants contribute to complex air quality problems such as the formation of ground-level ozone (smog) and acid rain as well as negatively impacting local flora, fauna and bodies of water. Electricity demand rises for air-conditioning, increasing emissions of greenhouse gases, contributing to global climate change. The annual mean temperature of a city with \\\>1m people is 1-3°C warmer than its surrounding and can be up to 12°C warmer at night. UHI causes thermal discomfort for people, deteriorating public health due to increased general discomfort, exhaustion, heat-related mortality, respiratory problems and heat stroke.SJH Driveways (paving specialists) in partnership with the University of Wolverhampton (experts in materials science and engineering) are developing Envirosurface, an innovative reflective paving surface that contains higher levels of UV/IR reflection with a higher albedo index, therefore, absorbing less solar energy and decreasing heat pollution. Alongside the surface's UHI-decreasing properties, it will comprise of recycled materials, be durable with limited deterioration from abrasion and oxidation, and require lower maintenance due to its high structural integrity.Decreased UHI will reduce electricity costs for air conditioning for commercial businesses and residents and will have a positive effect on people's health with less heat related deaths and discomfort.
