18 Smart buildings What is a smart building? Is it different than a building with an automation system? What are the features a smart building? Discuss with your neighbour 18

19 Smart building definition There is no standardized definition Example by Clements-Croome (2009) responsive to the requirements of occupants, organisations and society. sustainable in terms of energy and water consumptions besides being lowly polluting in terms of emissions and waste healthy in terms of well-being for the people living and working within it functional according to the user needs 19

20 Smart buildings Something smarter than the usual Smart buildings learn based on measured data human interaction Building automation typically control heating, ventilation and cooling smart buildings cover much more 20

21 Smart building trends analytics 21

22 Smart building trends integration (Schneider) 22

23 Smart building trends internet of things (Enocean) 23

24 Smart building trends BIM, VR and AR 24

25 Smart building trends self learning systems 25

26 Smart building trends - user interface 26

27 Smart building trends - human as a sensor (Microsoft) 27

28 Smart building trends - parking (Smart parking) 28

29 Smart building trends indoor positioning (Tieto) 29

30 What is considered smart today? From technology-oriented to human-centered perspective Supports user needs in everyday life Building is not smart if it does not make the people inside smarter 30

35 Home assignment Search (e.g. from internet) Two examples of good indoor lighting Two examples of indoor lighting that require improvement Take screenshots of the examples Argue your choices Why did you choose the examples? How would you make good examples even better by using integration to building automation? What is wrong with poor examples? What could be done better? One photo + arguments per slide Work in pairs 35
