A sample case of an advanced lighting system in a educational building
The paper describes a case history of an advanced lighting control system designed and realized for a couple of classrooms of the University of Rome. The control is organized by adopting a BUS system with "distributed intelligence" without a central and with smart actuators. The control turns on/off and regulates the lighting output of two classrooms, according to the actual presence of activities and to the actual availability of daylighting. A classroom was arranged with a light solution consisting in “on-off switching” control and not changing the luminaires, a second classroom was arranged with an advanced solution consisting in the replacement of the luminaires with a “dimming” control. A third class identical to the other two was taken as a reference to compare the results, in fact the architecture includes a supervisory system that allows a remote meter of the energetic values for the three classrooms. The paper shows the results of a year of monitoring campaign and compares the results with the energetic evaluation done by the a suggested tool based on the Standard EN15193 methodology.
Impact of building automation, controls and building management on energy performance of lighting systems
In a lighting system design to estimate the actual energy efficiency of lighting control systems is an important goal since an accurate evaluation could help and guide designers towards the most appropriate control system. This paper analyzes the methodology for calculating energy consumption for lighting systems and the impact of the Building Automation and Control Systems (BACS). It promotes a comprehensive ecodesign of lighting systems consisting in the adoption of the appropriate lighting components and the adaptive partitioned architecture of electrical distribution system and lighting system in general and independent local systems. It allows structurally to satisfy in each sub-area lighting and energy performances and to provide a basic efficient control system suitable for a manual or automatic regulation.
Human Factors in Lighting
From the combination of knowledge and actions, someone can improve their skill and ability. It will lead them to live and work much better. This is why, the students, workers, or even employers should have reading habit for books. Any book will give certain knowledge to take all benefits. This is what this human factors in lighting tells you. It will add more knowledge of you to life and work better. Try it and prove it.
