The Effect of Solar Control Elements on Building Energy Consumption in Hot Dry Climate Regions The Case of Diyarbakır

Abstract

Solar control devices have a significant effect on providing indoor thermal comfort by minimizing annual energy costs in hot-dry climates. Within the scope of the study, the settlement pattern Şilbe 1st Stage Mass Housing settlement located in the city of Diyarbakır, which is located in the hot dry climate zone, was discussed. Horizontal-vertical solar control devices were placed on the transparent surfaces in east-west and northeastsouthwest directions, which give optimum results due to the shadow effect, by means of the DesignBuilder Simulation Programme, and the effect of annual heating and cooling energy load expenses was examined.This study aimed to examine the effect of solar control devices on energy saving in hot dry climate regions.As a result of the study, solar control devices placed in both east and west directions provided a significant decrease in annual energy costs. In addition, the types of solar control devices (horizontal or vertical) used had an impact on annual energy costs.As a result of the analysis, it was determined that horizontal solar control devices should be preferred in hot-dry climate regions. This study will be a guide for the studies carried out within the scope of energy efficient structure design of solar control devices.

Analysis of transparent building envelope renovations for indoor thermal comfort in an educational building

“…In the second phase, the evaluation of the scenarios is carried out using DesignBuilder (V6.1.8.021 and EnergyPlus 8.9), the BEM software designed to measure and control the thermal and lighting comfort and EC and generation of a building used in many similar studies (Zahiri and Altan, 2020; Aydın and Mıhlayanlar, 2020; Dudzinska, 2021; Akalp and Özyılmaz, 2023). According to the location of the building, calculations on the amount of heat gained and lost through the BE were done with the help of the DesignBuilder, which analyzes the energy flow by using the hourly data of the typical year and keeping constant IAT.…”

“…Depending on the overhang's depth and the transparent area on the façade, it is seen that it has a reducing effect on the cooling load. Recent studies show that this improvement can provide a gain of 3%-27% (Yao and Zheng, 2017;Akalp and € Ozyılmaz, 2023). However, although they are important applications in controlling solar gain, IAT reducing effect on their own is quite limited, usually below 1 8C (Dudzinska, 2021).…”

“…Both the passive design application and the solar control elements applied together with the technology have an effective role in reducing the cooling load and determining IEQ, especially in terms of thermal and visual comfort (Gadelhak et al. , 2013; Akalp and Özyılmaz, 2023). The most basic solar control is the use of overhangs (Yao and Zheng, 2017).…”
