The office buildings in Egypt, especially in Upper Egypt, reflect serious problems in achieving for energy efficiency as a result of increasing the use of mechanical refrigeration devices in office rooms, due to solar radiation and rising summer temperatures in recent years. Smart windows can play an important role in reducing significantly the energy consumption and maintaining energy inside buildings, also helps to control incoming solar radiation in order to minimize solar gain, especially in summer as well as ensuring the best natural lighting conditions without glare inside a room. This paper aims to evaluate the most efficient daylight and thermal performance of various types of the smart glazing and its impact on the energy consumption in the climatic conditions of one of the office buildings (Diwan governorate) in Sohag governorate as one of Upper Egypt governorates, with determining the best smart glass types for efficient use of energy. The paper follows the theoretical, applied, by studying types of smart glazing and their relation to achieving the energy efficiency. Then using (Energy Plus) simulation tool, which has been used in utilizing its modeling orientation (Design Builder) to study using types of smart glazing on the model of an office room in Building of Diwan governorate of Sohag in the four different orientations (North, East, South and West), when window-to-floor ratios (WFRs) (8%, 16%, 24% and 32%). The paper ends with a presentation of the most important results, recommendations and determination the best types of smart glass that provides energy, daylight without glare and providing greater comfort to users.

Abstract - Illumination forms an important factor in a building. Lighting, and especially its natural form, is an important element to be considered in an office building. Proper natural lighting in an office can create a way to economize on energy. Besides, it may create a conducive atmosphere, affecting the work spirit and inspire the zest of the employees, so a lighting system must be designed to reach the highest possible degree of effectiveness. The effectiveness of natural lighting can be regarded from the quantitative and qualitative angle. Attaining the purpose of naturadaylight is influenced by various factors, including the daylight apertures that let daylight or sunlight seep in, along with surfaces or panels that reflect light so that it bounces back. Therefore, we must find out how these daylight apertures and reflective surfaces influence the effectiveness of lighting in office buildings. The Rumah Kindah office in Jakarta happens to be one of the office buildings that make use of natural lighting with daylight apertures that are unique, along with several kinds of reflective surfaces. This type of research can be classified as descriptive-evaluative, making use of the quantitative-qualitative approach. The Rumah Kindah office as the object of rsearch consists of three work spaces displaying the characteristics of daylight apertures that are uniform but not exactly the same, and the same applies to the reflective surfaces, so the research was conducted in these three office rooms. The relevant set of data was collected by way of observation, taking measurements and through the medium of interviews held at the object of research as well as using software to support simulation for the sake of acquiring the data required. These data can be analyzed by employing the theories that are available. The analysis results indicate that the daylight apertures oriented to the East-West but differing in terms of type, position, dimension and material produce a quantity and quality that varies from space to space. Besides, the reflective surfaces inside and outside the rooms play an important role in attaining the desired effectiveness of natural lighting in each of the work spaces at the Rumah Kindah office in Jakarta.

High Rise Building

Majority of office buildings in China are appeared in forms of high-rise buildings and have a character of high construction-scale and high energy-cost. The daylighting in office can not only save the energy, but also meet the physical and psychological needs for eyes, and finally lead to higher work efficiency. Solving the daylighting problems in the high-rise office buildings is urgent. The core position in the high-rise building is an important factor to affect the light in office. In this paper, the author analyses the lighting characteristics of three types of the core position, which is core in the center of the building, core at the peripheral of the building and the core separated from the building. Combined with the natural lighting assistance measures, some design essentials were raised in this paper.

It is important for sustainability to reduce the energy demand of both existing and planned buildings. The requirements for workspace lighting clearly define the minimum light intensity that must be provided. The aim of the study was to verify if the selected office layouts independently fulfill the requirements of the Polish Norm for lighting of workplaces without the use of artificial light sources. The analysis took into consideration standard working hours of office buildings, that is from January to December, from 8 a.m. to 4 p.m. Interpretation of the obtained data allowed to select the layouts that maintain the most stable efficiency of natural daylight.

This paper explains the designed performances of the new CH2 building in Melbourne, Australia. CH2 is an environmentally significant project that involves biomimicry of natural systems to produce indoor conditions that are conducive to user comfort, health and productivity. This paper focuses on lighting and physiology and examines the solutions chosen for artificial and natural lighting and the likely effects these will have on building occupants. The purpose of the paper is to critically comment on the adopted strategy and, cognisance of contemporary thinking in lighting design, to judge the effectiveness of this aspect of the project with a view to later verification and post-occupancy review. The paper concludes that CH2 is an exemplar of lighting innovation that provides valuable lessons to designers of office buildings, particularly in the Melbourne CSD.
