The use of algorithms for light controlThe use of algorithms for light control Κεφάλαιο σε Βιβλίο Book Chapter 2018-10-262016enBecause light directly influences human health, requirements on lighting levels must be constantly fulfilled. The lighting control market represents, therefore, an innovative sector that empowers a start-up's potential and where customers are highly looking for solutions that have low costs and high life expectancy, and that are least intrusive. Consequently, the control algorithms implemented are crucial in order to maximize efficiency while satisfying all the aforementioned specifications. This chapter introduces light-control algorithms as enabler of differentiation, which is a key requirement for a successful start-up rollout. Moreover, the proposed control lighting systems are customized and implemented in three real operational environments: two hospitals and one office building, all located in the Mediterranean area. The implementations show significant energy savings with low up-front and installation costs: this demonstrates the importance of control algorithms in lighting systems as high energy savings are achieved and lighting requirements fulfilled. http://creativecommons.org/licenses/by/4.0/Start-Up Creation: The Smart Eco-Efficient Built Environment Cristalli Cristina Standardi, Laura Kolokotsa Dionysia Κολοκοτσα Διονυσια Papantoniou Sotirios Παπαντωνιου Σωτηριος Elsevier Artificial light Building automation Control algorithm Dimmable system Energy efficiency Hospital building Lighting standards Office building Start-up potential
