Also known as Smart building technology or Building automation. Building technology refers to equipment used to control and regulate technical installations in buildings and related planning. For example, it ensures that buildings are supplied with heating, water, and ventilation. The digitalization and automation of this technology open up new potentials about energy efficiency, safety, security, and comfort in the “smart home.” Systems can be programmed to make energy-efficient decisions regarding lighting and heating, for example. At the same time, active & assisted living (AAL) systems allow older people to continue living an independent life in their own home for as long as they wish to.
