“…Daylight is an essential resource for building users and it has a psycho-physiological role, impacting health and wellbeing [1,2]. It is also an important resource in terms of energy and economic efficiency, since the availability of daylight allows to lower the use of artificial lighting, and consequently of energy [3].…”

The Daylight factor is the reference parameter used in Energy Standard EN15193:2008 to assess daylight contribution in the energy performance of buildings. But its efficacy in putting in relation buildings energy performance, daylight availability and visual tasks is now a subject of discussion in literature. In fact, the daylight factor is a static indicator independent from building geometry and environmental parameters. From the energy point of view, it has still to be assessed if it can ensure when the switch of artificial light is needed, representing therefore the most disadvantageous outdoor illuminance conditions. The goal of this study is demonstrating if the daylight factor calculated in standard conditions (Overcast sky) is conservative respect to that calculated using the diffuse component of the horizontal illuminance under CIE (Commission Internationale de l'Éclairage) Clear sky. If so, Daylight factor (D) might be applied, possibly with suitable corrections, to estimate the energy requirements for lighting, keeping the results on the safe side. 

“…At the basis of these objectives there is the integrated planning of all the different aspects involved in the management of the building and the correct and optimized design of systems in order to obtain energy and economic savings. [9][10][11][12][13][14][15] In this view, the design of an indoor artificial lighting system involves a large number of variables which include photometric factors, economic and aesthetic considerations, energy, comfort and health issues [16][17][18][19][20][21] as well as effective use of equipment, material and technologies and integration with daylighting. [22][23][24][25] The growing demand for comfortable and energy efficient environments, made possible by the availability of new materials and technologies for the environmental control have led to the need for a thorough analysis of design techniques for the management of interior spaces.…”

Buildings are heavily responsible for energy consumption and CO 2 emissions. Increasing their energy efficiency is in the direction of the EU strategies; and this is consistent with EU Energy Performance of Buildings Directive (EPBD 2010/31/EU), 2010. In this view the design and management of daylight and artificial light can play a fundamental role. In this paper, a method to optimize indoor lighting design from energy efficiency, economic and environmental viewpoints is presented. The optimization was developed through the Genetic Algorithms technique and the optimal layout in terms of number, location and mounting heights of luminaires in a generic office room was evaluated. Solutions with different types of light sources, nominal luminous flux and photometric distribution curves were compared and the cost effectiveness of these alternatives was also considered. The systems resulting from the optimization show increased uniformity of illuminance, a reduction of the number of luminaires and a decrease of the maximum UGR values, proving the effectiveness of the technique in the lighting design field. Results show that current methods for lighting design can still be improved to achieve optimal configurations in terms of energy efficiency and cost effectiveness.

“…The lighting requirements for indoor sports facilities are specified in Europe, in the Technical Standard EN 12193 [17]. In addition to the lighting requirements, it is important also a verification of the photobiological safety and the health effects of the lighting sources, to whose emissions the athletes can be exposed for several hours a day [23][24][25][26], in accordance to what should be done for other environments intended for the permanence of people [27][28][29][30].…”

Abstract:In this paper, the authors propose a techno-economic comparative analysis between different lighting solutions, using, respectively, floodlight with metal halide lamps, luminaires with fluorescent lamps and LED floodlights. The comparison is aimed to identify general criteria for assessing the techno-economic sustainability of the use of LED lighting for indoor sports facilities, since this solution is very often proposed to achieve a reduction of the electrical power for lighting. From a technical standpoint, the analysis takes into particular consideration the aspects related to the satisfaction of lighting requirements, safety and energy efficiency. From an economic standpoint the investment, the operating and the maintenance costs are evaluated. To make comparisons on an economic basis, specific indicators are used. From the obtained results it is possible to highlight as the solution that uses the LED floodlights is characterized by highest energy efficiency. This solution requires a smaller number of luminaires and it has limited maintenance costs compared to the other solutions, but it has high investment costs, which involve reasonable payback times only when the sports facility is used intensively and for competitions of high level.
