Digitisation in existing buildings is not as widespread as in other sectors. A consequence is that buildings owners and occupants have generally a limited understanding of their building as an energy system. Improving the energy efficiency of existing buildings can and should be achieved through deep renovation. In comparison, smart technologies can increase the efficiency and the flexibility of buildings in a shorter term and with much less investments. The domOS project addresses the smart building sector through two axes.

In the first axis, technology, guidelines for an open, secure, multi-service Internet of Things (IoT) ecosystem for smart buildings are defined.The second axis deals with the development of smart services.
