在英格兰和威尔士的公共部门办公室股票能源使用的内部和外部特征的影响进行了探讨,使用数据库的2600显示能源证书(德克斯)结合其他来源的分类办公室信息。DEC办公室的基准显示,以配合化石能源的热量和电力消耗的中位数很好。分析的供暖,通风和空气调节(HVAC),大小,占用密度,楼龄,位置和应课差饷租值。虽然较新的办公室比较旧的办公室具有较低的典型化石热消耗,但这被较高的电力消耗所抵消,导致较高的典型二氧化碳排放量。这对英国2050年的减排目标产生了影响,表明虽然专注于热性能的建筑法规取得了成功,但重点关注电力消耗(包括监管和非监管)是关键。研究结果还与英国所有办公室的现有基准进行了比较,将样本分为四种通用类型,并与一项类似的小型私人办公室研究进行了比较。这表明,公共办公室通常使用的能源比以前预测的一般基准要少,特别是对于声望较高的办公室。
The influence of internal and external characteristics on energy use in the public sector office stock in England and Wales is explored using a database of 2600 Display Energy Certificates (DECs) combined with other sources of disaggregated office information. The DEC office benchmarks are shown to match the median fossil thermal and electrical consumptions well. Analyses of heating, ventilation and air-conditioning (HVAC), size, occupancy density, building age, location and rateable value are considered. While newer offices are shown to have lower typical fossil-thermal consumption than older offices, this is counterbalanced by higher electrical consumption, resulting in higher typical CO2emissions. This has implications for the UK's emissions reduction targets for 2050, indicating that while building regulations that focus on thermal performance have been successful, a focus on electrical consumption (both regulated and unregulated) is key. The results are also compared with existing benchmarks for all UK offices, splitting the sample into four generic types, and compared with a similar smaller study of private offices. This indicates that public offices typically used less energy than the general benchmarks had previously predicted, particularly for prestige offices.
