Lighting represents a significant component of the energy spent in commercial and office buildings. It is well known that the use of advanced lighting controls can determine significative energy savings, but its quantification is not always clear. The authors suggest a methodology to quantify the energy performance of the lighting systems, taking into account the influence of the controls. The proposed...
The authors suggest a methodology to evaluate the energy performance of lighting systems. The methodology is useful in the designing time to optimize, luminaires, system and control and in management time to certificate the systems. Four energy performance indicators are suggested: EPL for the luminaires like a label, EPS for the lighting systems arrangement, EPC for the control system and EPG for...
This paper specifies overall indicators to express energy performance of interior lighting systems including luminaires aspects, luminaires arrangements aspects and the impact of the lighting control systems on lighting systems energy performance. Moreover, the authors suggest ways to express energy requirements for the design of new lighting systems or renovation of existing lighting systems, and...
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...
