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更多的热污染，被称为城市热岛效应(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，以及对当地动植物和水体的不利影响。空调用电需求上升，温室气体排放增加，导致全球气候变化。拥有100万人口的城市的年平均气温比周围高1-3摄氏度，夜间最高可高达12摄氏度。城市热岛会引起人们的热不适，由于普遍不适、疲惫、与热有关的死亡率、呼吸问题和中暑而恶化公共健康。SJH车道(铺路专家)与伍尔弗汉普顿大学(材料科学和工程专家)合作正在开发EnviroSurface，这是一种创新的反射式路面，包含更高水平的UV/IR反射，具有更高的反照率指数，因此，吸收更少的太阳能，减少热污染。除了减少表面的热重，它还将由回收材料组成，耐用，磨损和氧化造成的损坏有限，由于其高度的结构完整性，需要较低的维护。减少热重将降低商业企业和居民的空调电力成本，并将以较少的与热有关的死亡和不适对人们的健康产生积极影响。

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.
