United Nations set Sustainable Development Goals and this paper focuses on 7th (Affordable and Clean Energy), 9th (Industries, Innovation and Infrastructure), and 13th (Climate Action) goals. Climate change is a major concern in our society; for this reason, a current global objective is to reduce energy waste. This work summarizes all main approaches towards energy efficiency using Artificial Intelligence with a particular focus on multi-agent systems to create smart buildings. It mentions the tight relationship between AI, especially IoT, and Big Data. It explains the application of AI to anomaly detection in smart buildings and a possible classification of Intelligent Energy Management Systems: Direct and Indirect. Finally, some drawbacks of AI approaches and some possible future research focuses are proposed.

A huge reason behind Sonos' success is the company's adaptability. Whenever a new audio streaming service comes along -- and as the industry evolves and pushes new formats like lossless and Dolby Atmos spatial audio -- Sonos is always right there trying to support what's new. For voice assistants, Sonos offers both Amazon Alexa and Google Assistant on its smart speakers. And the company also widely supports Apple's AirPlay 2 across its current product lineup. That's all on top of the whole-home audio platform that Sonos has built its brand on. But to stay so nimble and adaptable, Sonos constantly needs to be looking forward and have some sense of what's coming down the technology pike.

As companies unveil their new smart home devices at the 2022 CES tech show, underway now in Las Vegas, much of the hype involves Matter, an open-source connectivity standard built around a shared belief that smart home devices should seamlessly integrate with other systems and be secure and reliable. If you like devices, you are probably among the 66% of households that have smart home devices, according to Deloitte. We also know you don't just stick with one company or brand, but probably have purchased from at least half a dozen different companies. That's why for any company launching a smart home device this year, having Matter support will be helpful. Not only is the protocol being developed by some of the biggest tech companies -- think Apple, Amazon and Google -- and smart home device makers, it is designed to finally fix the issues around fragmented smart home systems so that all of your devices can be easily set up and routed from one place.
