Smart technologies in buildings

Cost-effective means for creating healthy, energy-efficient and comfortable buildings.

The potential of smart technologies in the building sector was heavily emphasised in the 2018 revision of the European Energy Performance of Buildings Directive (EPBD) and the concept of a Smart Readiness Indicator (SRI) was introduced.

What makes a building smart

The ‘smartness’ of a building refers to its ability to sense, interpret, communicate and actively respond in an efficient manner to changing conditions in relation to

  • the operation of technical building systems,
  • the external environment (including energy grids)
  • demands from building occupants

The SRI rates the smart readiness of buildings (or building units) in their capability to perform 3 key functionalities:

  • optimise energy efficiency and overall in-use performance
  • adapt their operation to the needs of the occupant
  • adapt to signals from the grid (for example energy flexibility)


The SRI will raise awareness of the benefits promised by smart building technologies, such as building automation and electronic monitoring of building systems including heating, hot water, ventilation, lighting, etc.

Through the implementation of the SRI framework, technological innovation in the construction sector becomes supported, and thus it creates an incentive for the integration of cutting-edge smart technologies in buildings.
