Performance prediction and design optimisation of an integrated light pipe and artificial lighting systemPerformance prediction and design optimisation of an integrated light pipe and artificial lighting system Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2018-10-032016enThis paper describes recent research on the prediction of the performance of light pipes and the ways to optimise their design, in order to house artificial lighting, able to supplement daylight in a space. The research has resulted in an algorithm, for the easy and quick calculation of the interior illuminance provided by light pipes, and in a procedure for the calculation of the power of the necessary artificial lighting (light emitting diodes [LEDs]) and the energy savings for lighting, due to the daylight provided by the light pipes and the daylight linked controls of the LEDs. http://creativecommons.org/licenses/by/4.0/International Journal of Sustainable Energy357675-685 Vasilakopoulou Konstantina Βασιλακοπουλου Κωνσταντινα Synnefa Afroditi Kolokotsa Dionysia Κολοκοτσα Διονυσια Karlessi Theoni Santamouris, Matheos, 1956- Taylor & Francis Energy savings LEDs Light pipes Performance algorithm
