全球气候变化正在使日本温和的气候明显变暖，预计这将对建筑能耗产生重大影响。气候变化对办公室冷热负荷的潜在影响也通过三个地点的热分析模拟在三个时期进行了调查；1981-2000年、2031-2050年和2081-2100年。这项研究表明，在IPCC的A2碳排放情景下，如果全面实施本文所述的措施，预计将大幅减少能源消耗。由于区域气候特征和气候变化，这些速率在每个地点和每个时期有所不同。二氧化碳减排目标将取决于未来的电力转换因素，而由于福岛核事故引发的国家能源计划修订，这一因素可能会恶化。日本仍然有大量能源效率低下的旧办公室（1981年以前）。如果有比这里所介绍的更具体、更先进的技术，就可以实现更大的节能。一项简短的经济分析表明，这些措施可以与核能发电相竞争。总的来说，日本的办公楼在不使用核能发电的情况下，有巨大的潜力来减少能源需求和相关的二氧化碳排放。
Global climate change is making the mild Japanese climate significantly warmer, which is expected to have a substantial impact on building energy consumption. The potential impacts of climate change on the cooling and heating loads for offices are also investigated by means of thermal analysis simulations at three sites over three periods; 1981–2000, 2031–2050, and 2081–2100.This study reveals that under the IPCC’s A2 carbon emission scenario, substantial reductions of energy consumption are expected if the full measures reviewed here are implemented. These rates differ in each location and each period due to regional climate characteristics and climate change. CO2emissions reduction targets will depend on future electricity conversion factors which could worsen due to revisions of the national energy plan triggered by the Fukushima nuclear accident.Japan still has a vast quantity of energy inefficient old offices (pre-1981). With more specific and up-to-date technologies than those reviewed here, even greater energy reductions could be completed. A brief economic analysis suggests that these measures could be competitive with nuclear power generation.Overall, office buildings in Japan have enormous potential to reduce energy requirements and related CO2emissions without resorting to nuclear power generation.
