当地的室外气候和建筑特点在很大程度上影响着建筑的能源使用。为了设计节能和耐候性强的建筑，从早期设计阶段开始就了解建筑使用寿命期间的能源需求是很重要的。本文概述了加热和冷却度日法的不同变体。此外，还使用一个允许对流的气候模式，在2.8公里的高分辨率网格上获得比利时RCP 8.5（高端）气候变化情景的加热和冷却度天数（基线温度为18°C）。本文的重点领域是比利时。结果表明，在1976-2004年（3189 HDD）和2070-2098年（2337 HDD）之间，HDD减少了27%。相比之下，在同一时间内，CDD从167 CDD增加到401 CDD，增加了2.4倍。此外，与农村地区相比，城市地区的平均硬盘减少幅度较小。就CDD而言，城市地区和比利时东北部的绝对增幅更高。
The local outdoor climate and building characteristics influence the energy use of a building to an important extent. To design energy efficient and climate robust buildings, it is important to get insights into the energy demand over the building's service life from the early design phase onwards. This paper presents an overview of the different variants of the heating and cooling degree day method. A convection-permitting climate model is furthermore used to obtain heating and cooling degree days (for a baseline temperature of 18 °C) for the RCP 8.5 (high-end) climate change scenario for Belgium on a high-resolution grid of 2.8 km. Area of focus for this paper is Belgium. The results demonstrate a decrease of the HDD with 27% between 1976–2004 (3189 HDD) and 2070–2098 (2337 HDD). In contrast, the CDD were found to increase with a factor 2.4 from 167 CDD to 401 CDD in the same timeline. Smaller reductions in average HDD were moreover found in urban areas compared to rural areas. For the CDD, a higher absolute increase was found for urban areas and the Northeast of Belgium.
