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越来越多的热污染，被称为城市热岛效应（UHI）。这些热污染物导致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产生负面影响。空调用电需求增加，温室气体排放增加，加剧全球气候变化。一个拥有100万人口的城市，其年平均气温比周边地区高1-3℃，夜间最高可达12℃。热岛热病使人们感到热不适，由于全身不适增加、疲惫、与热有关的死亡率、呼吸问题和中暑而使公共健康恶化。SJH Driveways（铺装专家）与伍尔弗汉普顿大学（材料科学与工程专家）合作开发环境表面，这是一种创新的反射铺装表面，含有更高水平的紫外线/红外反射，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。除了表面的uhi降低性能外，它将由回收材料组成，耐用，磨损和氧化的退化有限，并且由于其高结构完整性，需要较少的维护。降低全民医疗保健将减少商业企业和居民使用空调的电费，并将对人们的健康产生积极影响，减少与热有关的死亡和不适。

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.
