DIN V 18599-4 STANDARD-BASED BUILDING ENERGY EVALUATIONPERFORMANCE IN TERMS OF ILLUMINATION

Abstract

The deficiency of energy resources which is a result of the increase in world population and the rapid development of technology impels the human being to use the available resources in an efficient way. From this point, Berlin-based DIN issued a standard with the name DIN V 18599 Energy Efficiency in Buildings. In this study,a building in Istanbul, TURKEY is considered to evaluate the energy need for lighting requirements based on the related standard. Study was conducted on an actual structure. The annual amount of energy required for lighting the entire plaza is calculated. The most important result of this study is that there are many parameters like as type of the use of space, facade direction, and slope of the roof, which affect the result of the energy needed for lighting in the buildings. These parameters must be considered for attentive and in-depth analysis, otherwise significant errors can occur in the results. The results showed that energy consumption of the spaces, that are illuminated by daylight and not illuminated by daylight, can be different from each other.
