Abstract- A good design of light holes in buildings can be done to maximize the potential for natural lighting in tropical countries. The building of badminton sports is one of the functions of a wide span building that is sensitive to natural lighting and requires special techniques in incorporating natural light into it because of its wide span. There are three aspects of visual comfort that must be met by lighting design in badminton sports buildings, namely 2% daylight factor, the distribution of illumination and glare effects. The three aspects of visual comfort will be the starting point of this research as a research variable. This study aims to determine the effect of design elements on natural lighting performance on the Pancasona Sportcenter Earth study object by exploring design elements. The study was conducted by evaluating the performance of the object of study and analyzing the influence of site and building elements on the performance of natural lighting in buildings. From the evaluation of natural lighting performance in the study object, it will be known that the design elements that have the most influence on natural lighting on the badminton court. Design elements that have the potential to improve the performance of natural lighting in the object of study will be explored. Exploration is done by simulating the Velux computer program to create controlled conditions. Based on the results of the evaluation, the study object has not reached the applicable visual comfort standard with a 0.1% daylight factor value, the distribution of illumination is less uniform, and there is no glare. Design elements that have the potential to improve visual comfort in buildings are the position of the net on the interior of the building, the width of the openings and the position of openings in the building, these three elements will be explored further in an effort to improve visual comfort. The exploration results that provide the closest standard value are an exploration of the sawtooth type design, with the value of daylight factor 1.1%, the distribution of illumination most evenly between all explorations and no glare on the field throughout the year. Based on exploration results, each element of design explored will improve the performance of different natural lighting depending on the needs of the building and space activities. Key Words: Natural lighting, badminton, wide span, daylight factor, illumination, glare, footprint, building, natural lighting performance.

This study allowed appreciating hygrothermal behavior, thermal comfort and the visual comfort of an existing Nubian vaulted building in the city of Ouagadougou. To achieve that purpose, we measured parameters such as the temperature and relative humidity of the indoor and outdoor environments as well as illumination by daylight inside the studied building. The measurement campaign consisted of two (02) series of three (03) days in January 2018: one series with insulation of the louvered openings by polystyrene and the other series without the insulation. We carried out the measurements of relative humidity and illumination at 7, 10, 12, 15, 17, 20 and 22 o'clock and adopted a one-hour measurement time step for temperatures. The analysis of these parameters showed that the level of natural lighting in the building was insufficient. In addition, for the indoor ambiance, we have obtained indoor thermal amplitude less than 1.5°C, a decrement factor of less than 6%, a time lag of 6 to 8 hours. As for operative temperatures, they are within the thermal comfort zone of the Givonni diagram. As for the couple (Temperature, Relative Humidity), the thermal comfort zone proposed by Givonni is reached when the louver openings are insulated.

Glazing surfaces strongly affect the building energy balance considering heat losses, solar gains and daylighting. Appropriate operation of the screens is required to control the transmitted solar radiation, preventing internal overheating while assuring visual comfort. Consequently, in the building design phase, solar control systems have become crucial devices to achieve high energy standards. An operation based on well-defined control strategies can help to reduce cooling energy consumption and ensure appropriate levels of natural lighting. The present study aims at investigating the effect of smart screening strategies on the energy consumption of a test building designed in the Mediterranean climate. With the aim of automatically setting the inclination of venetian blind slats, the necessary equations are analytically found out and applied. Equations obtained are based on the position of the sun with respect to the wall orientation. In the case of a cloudy day or an unlit surface, empirical laws are determined to optimize the shielding. These are extrapolated through energy simulations conducted with the EnergyPlus software. Finally, using the same software, the actual benefits obtained by the method used are assessed, in terms of energy and CO2 emissions saved in a test environment.

Abstract Light via our eyes influences visual performance, visual comfort and visual experience, but also affects several health related, non-image-forming (NIF) responses. New metrics have been developed to quantify the NIF effects of light. In order to incorporate these in lighting design practice, simulation tools are required that are able to process information about the spectral distribution of light sources and materials. However, most of the tools currently used for daylight and electric light simulations simplify the spectrum into RGB (Red, Green, Blue) colour values. This paper presents an overview of the currently used programs for simulating the NIF effects of light in building design and discusses the possibility of using existing spectral rendering software as an alternative. A review of literature shows that mostly Radiance or Radiance-based programs have been used so far, but new user-friendly tools could employ existing spectral rendering tools. As the NIF effects of light gain greater importance in lighting design, new simulation workflows are needed. This paper aims to support the development of future workflows by presenting the current state-of-the-art.

Study Results

Our present research, starting from a previous study, aimed to define a methodological approach for sustainable lighting designs in a historical library, focusing on lighting quality, mainly obtained from the optimal use of natural light and its combination with the artificial one. A historical Florentine monastery, which is now a university library, was used as a pilot project. The proposed method forms an essential part of widening and deepening the recent study. Results have shown that this method will allow for adaptive lighting, based on the optimal control and use of natural light, historical–philological re-reading of the space, cultural heritage preventive protection and conservation, with the aim of building adaptive reuse, and it can be extended to similar cultural heritage cases, but also non-listed buildings and current designs. This research demonstrates how a correct natural lighting design can be a tool for sustainable refurbishment, guaranteeing cultural heritage conservation and preventive protection, and recovery of the historical, architectural and philological value of old and/or listed buildings, which have been converted to uses, often diametrically opposed to the original ones.

This paper discusses the rise of human-centric lighting and its current status in lighting. We summarise the human benefits associated with light and lighting and show that human-centric lighting has sound motivations, despite being tainted by misleading marketing claims. The phrase integrative lighting avoids the hype and encapsulates what lighting aspires to be. Embodied in these concepts are some things old and some things new. The old is twofold. First, without diminishing the value of lighting products, the core ingredient for good human outcomes is good design, driven by a design team. Second, light is still for vision, and lighting for visibility, visual comfort and visual amenity is as important as ever. Complementing the old is new awareness and responsibility for how light and lighting influence non-visual responses in humans. Circadian, neuroendocrine and neurobehavioural responses are important for human health and should be considered on-par with visual responses. This awareness leads toward lighting design solutions with increased contrast between day and night. The parties responsible for addressing non-visual responses to light and lighting are evolving. Architects, lighting professionals, lighting equipment manufacturers, medical professionals, building owners and individuals all have a stake, but who should drive decisions and in what proportion?

There are often no windows and lack of natural light in the most of underground space, so lighting design is the most basic for most underground architectural design. Natural lighting is not only for comfortable indoor energy-saving and healthy light environment, but also for the good indoor environment. We need to use natural light and artificial lighting conduction system to offset the lack of natural light and improve the effect of underground space of natural light.
