Studies on the contribution of daylight at indoor environment within a stand-alone building throughout a year, a software-based approach

Abstract

The building design incorporates lighting design in a significant way. Energy consumption in a building can be decreased with the use of natural lighting. The foundation of the planning concept is aesthetic levels. However, in order to achieve an energy-efficient building design, the idea of natural illumination must be taken into account. Understanding how lighting intensity affects a building's opening size, depth of space, and height was the goal of this study. Analyzing statistical information about space illumination levels from DIALux is the quantitative research method. The amount of openings in a building's exterior has an impact on how bright a space is. The depth of the space and the floor height of the building are both impacted by the dispersion of natural light. Based on this finding, it is anticipated that when constructing a structure, attention must be paid to the building facade in order to ensure that natural light penetration into the building is not excessive and to prevent undesirable effects like glare, extreme brightness, and contrast. 1. Introduction Daylight is a valuable resource that is constantly present and unlikely to become scarce in the near future. It also has the extremely unique power to change an interior environment from one of uninspired monotony into one that is psychologically uplifting. One of the key reasons architects aim to allow daylight to enter a structure wherever possible is that it has the capacity to both enlighten an area and make it more fascinating. Depending on the specific use of a room, the amount of change in daylight that is desirable or tolerable fluctuates from moment to moment in intensity and quality. For some usage, including in rooms, lighting regulations might be fairly rigorous, but many other applications allow for more flexibility. The quantity, quality, and distribution of light are the three elements that must constantly be taken into account in order to produce good lighting. Intense light sources, such as sunshine or electric light, can cause considerable glare, which can be both inconvenient and detrimental to a user's ability to perform their activity. This is the reason that carefully planning the design of openings in a building's fabric is necessary to manage the admission of sunlight into an area. Section 2 describes the many ways in which daylight and sunlight can be brought into a building and how well the different options perform. Section 3 examines the ways of controlling daylight and electric light so that internal conditions are maintained within design limits, and energy use reduced. Section 4 reviews the tools available to help incorporate daylight into building design and predict its performance. Section 5 gives an Analysis of studies of daylight systems that have been demonstrated.
