动态热性能

免费的工具用于计算热性能Arup开发后，混凝土中心已经推出了建筑元素。

目前正在修改有关能源保护的建筑法规的第L部分，以及用于住房的合规工具（标准评估程序）。SAP的更改中包括对住房中热质量的影响进行更严格的处理，以考虑其在被动设计中所起的作用。亚搏娱乐网站当适当使用时，热量可以通过提供一种捕获和缓慢释放出亚搏娱乐网站来自太阳和内部设备的自由热收益的方法来提高暖气季节的能量效率。

这减少了加热系统上的负载并减少了CO₂排放量，特别是在隔热良好的气密房屋中。修订考虑了这种被动加热效果，为了帮助设计师利用这一点，混凝土中心委托Arup开发了一种基于Excel的免费工具，用于计算地板和墙壁中的热量。亚搏娱乐网站

该方法基于BS EN ISO 13786，并与SAP完全对齐，允许轻松计算热质量值（也称为Kappa值）并直接输入到SAP软件中。亚搏娱乐网站如果需要，还会产生入学值，提供评估热质量的替代方法。亚搏娱乐网站

该工具的另一个特点是其钙的能力ulate decrement. This is a property of thermal mass which describes the way in which the density, heat capacity and thermal conductivity of a wall for example, can slow the passage of heat from one side to the other (decrement delay), and also attenuate gains as they pass through (decrement factor). Designing for a long decrement delay of around nine hours or more, and a low decrement factor can help reduce overheating problems in summer.

生产这个工具是一个成长的动机g need among architects and engineers for more information about the thermal properties of construction elements other than just their U-value. This is needed to help optimise the passive performance of buildings and ensure a high level of inherent energy efficiency. Going forward, it is likely that far more attention will be paid to getting this right given the forthcoming changes to Part L and SAP. Another driver is the issue of climate change adaptation, which is starting to result in greater scrutiny construction materials and their thermal properties.
