将全球变暖限制在1.5摄氏度以下需要能源系统的快速脱碳。减少能源需求在可持续能源过渡中发挥重要作用。在这里，我们探讨了低能耗实践的出现，包括新的行为和采用更高效的技术，可以在多大程度上有助于降低能源需求，从而减少CO2排放。为此，我们设计了三个详细的能源消费概况，可以通过个人在当前和未来的富裕地区。将空调设置为更高的温度或广泛使用高效淋浴喷头在多大程度上减少了总能源需求？我们调查了2050年和2100年全球范围内新做法的潜力。与当前趋势相比，采用新的节能做法可以在2050年将全球建筑物的能源需求减少47%，在2100年减少61%。这一大幅下降主要是由于热水使用量的变化，建筑物的隔热以及消费者对空调和热泵的选择。新的行为和高效的技术可以为减少建筑物的能源需求做出重大的长期贡献，从而促进严格的气候变化减缓目标的实现，同时限制能源供应系统对可持续性的不利影响。
Limiting global warming below 1.5 degrees C requires rapid decarbonization of energy systems. Reductions of energy demand have an important role to play in a sustainable energy transition. Here we explore the extent to which the emergence of low energy consuming practices, encompassing new behaviors and the adoption of more efficient technologies, could contribute to lowering energy demand and thereby to reducing CO2 emissions.To this end, we design three detailed energy consumption profiles which could be adopted by individuals in current and future wealthy regions. To what extent does the setting of air conditioners to higher temperatures or the widespread use of efficient showerheads reduce the aggregate energy demand? We investigate the potential of new practices at the global level for 2050 and 2100.The adoption of new, energy saving practices could reduce global energy demand from buildings by up to 47% in 2050 and 61% in 2100 compared to a scenario following current trends. This strong reduction is primarily accounted for by changes in hot water usage, insulation of buildings and consumer choices in air conditioners and heat pumps. New behaviors and efficient technologies could make a significant long-term contribution to reducing buildings' energy demand, and thus facilitate the achieval of stringent climate change mitigation targets while limiting the adverse sustainability impacts from the energy supply system.
