Wireless connectivity and the Internet of Things are fundamentally reshaping the buildings we live, work, and shop in, increasing comfort and convenience, saving resources, and enabling new business models. Besides making them more comfortable, convenient, and fun, connected buildings can save more energy, manage resources more efficiently, and offer higher levels of safety and security than traditional buildings, adding value from moment to moment and increasing the overall financial worth of real estate. In addition to being foundational building blocks for smart cities, connected buildings will play an important role in addressing numerous societal challenges, including the climate crisis, resource scarcity, demographic changes, and unrelenting urbanization.
