The proliferation of consumer Home Automation Systems (HAS), which is increasingly based on the Internet of Things (IoT) architecture, comes with added costs for the additional electrical energy required to power the automation interfaces and the standby energy consumption required to maintain connectivity and/or “smartness”. In this article, we use a bottom-up approach to develop novel system-level energy consumption models for consumer HAS devices and quantify the energy consumption for a typical HAS. We then assess the potential impact on global Information and Communications Technology (ICT) energy use. We show that, on average, HAS may consume over one-third of the annual energy used in a mid-sized home, with non-trivial impact on the global ICT energy footprint.

“智能”不是免费的：消费者家庭自动化系统的能耗

越来越多地基于物联网 (IoT) 架构的消费者家庭自动化系统 (HAS) 的激增伴随着为自动化接口供电所需的额外电能以及维持连接和维护所需的待机能耗的成本增加。 /或“聪明”。在本文中，我们使用自下而上的方法为消费者 HAS 设备开发新颖的系统级能耗模型，并量化典型 HAS 的能耗。然后，我们评估对全球信息和通信技术 (ICT) 能源使用的潜在影响。我们表明，平均而言，HAS 可能消耗中型家庭每年使用的能源的三分之一以上，对全球 ICT 能源足迹的影响非常大。
