Kinetic facades for maximizing human comfort and increasing space use efficiency in highly glazed building interiors

Ulular, Ilgın Büke
Environmental problems are one of the major concerns for the present time, and the building construction sector has a significant impact on the environment. So, existing buildings should be evaluated for efficient use. In public buildings where people can choose seats, efficient space use can decrease because of discomfort. Facades are significant to provide these conditions. Kinetic facades can be considered as an efficient option with their technological systems. In the literature, few studies are related to improving thermal and visual comfort in public buildings with large glazed areas. This research investigates the impacts of thermal and visual comfort affecting space use in a case study building with glazed facades and the possible enhancements of applying kinetic facades. The research is based on a case study-building analysis. Climate graphs of Ankara were taken from Climate Consultant. Temperature data was collected by TESTO 405-V1. According to these results, the most uncomfortable section was selected as the focus study. The illuminance data was collected by RO 1335 lux-meter for one of the floors, and the simulations were calibrated with Velux Daylight Visualizer according to the actual results. A fixed shading and two different kinetic facades were proposed to enhance the thermal and visual comfort conditions. Kinetic morphologies were selected from the literature and optimized by Galapagos according to the illuminance data. All simulations were conducted by Ladybug and Honeybee. Operative temperature, illuminance, daylight factor, and useful daylight illuminance were simulated for all scenarios. The best result was achieved with the kinetic façade with square modules on the ground floor, with a 63% improvement in illuminance. Eventually, it was determined that the proposed kinetic morphologies have different effects on diverse floors; however, they can offer the most effective solution to improve visual and thermal comfort conditions in all scenarios.


Educational building retrofit under climate change and urban heat island effect
Akkose, Gizem; Akgül, Çağla; Gürsel Dino, İpek (2021-08-01)
Climate change (CC) and urban heat island (UHI) are important environmental forces that have serious consequences for the existing buildings, such as increased resource consumption and environmental footprint, adverse human health effects and reduced occupant comfort. In this context, educational buildings represent a critical category amongst other building typologies, due to their high energy use, high occupant density, atypical daily/annual occupancy patterns, and their occupants’ high vulnerability to h...

The construction sector, being one of the greatest consumers of raw materials, has been under the spotlight for many years in parallel to the increased environmental awareness. Specifically, building of walls are of critical importance. For each wall element, there are different manufacturing steps; but, in general, the emissions from a wall element are dominated by one or two manufacturing steps. For example, for concrete, both energy use and calcination in cement manufacturing are in focus; for clay brick...

As the construction industry is one of the dominant contributors to the world’s total CO2 emissions and it has huge negative impacts on the environment, sustainable construction has become a key aspiration in the field. Through utilizing eco-friendly design and resource efficiency, sustainable construction is considered as the main concept to create and operate a healthy built environment. Although sustainability has been demonstrated as a timeless objective for continuous development in Turkey’s government...
Energy consumption of a day-occupied building utilizing phase changing material incorporating gypsum boards
Akgül, Çağla; Gürsel Dino, İpek (null; 2018-09-14)
In the architecture, engineering and construction industry, there is an urgent need for a shift to low-energy, sustainable buildings to address the environmental concerns, increase occupant comfort demands and lower the operational cost of buildings. In this direction, one of the most effective technologies is using PCM’s (phase change materials) as part of building envelopes. PCMs can increase building performance by increasing the thermal storing capacity of buildings by decreasing the heat transfer betwe...
Climate Change Impact on Multi-Objective Optimization: A Case Study on Educational Buildings
Akın, Şahin; Işeri, Orçun Koral; Akgül, Çağla; Erdoğan, Bilge; Gürsel Dino, Ipek (null; 2020-05-23)
The changing weather conditions due to global climate change is expected to have a direct impact on buildings’ energy demand and occupant comfort. These conditions are estimated to become more challenging for educational facilities due to their high occupant density and the students’ sensitivity to heat. This study aims to present an approach for a comparative analysis for multi-objective optimization results that are projected under different climate change conditions. Two separate optimization processes w...
