Comparison of Architectural Design Parameters in Traditional Buildings in Terms of Energy Performance for Future Housing Design
(Izmir Institute of Technology, 2020) Çoşkun Öner, Özden; Kazanasmaz, Zehra Tuğçe
Architectural studies re-orient through traditional architecture because of the energy crisis. The purpose of this study is to examine the architectural design parameters of traditional dwellings in terms of energy efficiency for future housing design in a hot humid climate. The case of this study is the 19th Century İzmir Houses. Two base case buildings with two and single-story were determined. Onsite measurements were taken from these buildings to identify the building material properties and to understand their thermal behavior. They were modeled and simulated with the DesignBuilder energy simulation program. The calibration and validation processes were conducted on these models. Two and single-story 114 types of İzmir Houses were modeled using the base drawings of the actual examples of these types and the validated material properties of the base case buildings in two different settlements where they are most frequently seen. The energy consumptions of these models were simulated. The statistical analyses were applied to examine the relationship between the source energy consumption per square meter and the design parameters of İzmir Houses. The design parameters such as the location of the hall, plan type, the existence of the basement, window to wall ratio, wall to floor ratio, window to floor ratio, total building area, wall to volume ratio, settlement pattern were found effective on the building energy performance. The least energy-consuming two-story İzmir houses type has a basement and side hall plan while the single-story house has a basement and central hall plan.
Categorization of Manual Lighting Control Behavior Patterns Based on Interior Layout in Offices
(İzmir Institute of Technology, 2016) Cılasun Kunduracı, Arzu; Kazanasmaz, Zehra Tuğçe
To reduce energy consumption due to lighting, variety of methods such as energy efficient products, daylight and lighting control systems, simulation softwares are being used. However, these methods may fall short of their potential if the end user, occupants, are not taken into consideration. Energy consumption due to lighting can be reduced further by understanding building occupants’ needs and behaviors. In this study, to understand user behavior for lighting, manual lighting control of occupants were examined. This examination compromises physical, temporal and architectural factors which affect manual lighting control behavior. Especially the focus was on interior layout to observe the relation between the architectural parameters and manual lighting control behavior. The goal of the research and experiments of this dissertation was to obtain realistic manual lighting control data in offices. First of all, various parameters including physical, visual, occupancy and architectural were observed and statistically analyzed by the conducted questionnaire, to find the most triggering/inhibiting factors for manual lighting control. Secondly three private offices were equipped to monitor the change in manual lighting control behavior with regards to occupancy, daylight penetration and interior layout. Results used to generate from the fuzzy model which offers more detailed classifications on manual lighting control probabilities. Gathered results showed that interior layout has a significant contribution to manual lighting control. As a result, if architects/lighting designers/researchers utilize the provided classifications of the tested parameters on the future studies, they can reduce energy consumption while increasing user satisfaction.
A Proposal for a Retrofitting Model for Educational Buildings in Terms of Energey Efficient Lighting Criteria
(Izmir Institute of Technology, 2015) Bayram, Göze; Kazanasmaz, Zehra Tuğçe
It has been crucial to benefit from daylighting and artificial lighting together as an integrated system in educational buildings to use energy efficiently during the day, since a well-designed lighting increases learning and working performance. The aim was to find the optimum values for daylighting to achieve visual comfort conditions and artificial lighting design parameters for minimum energy consumption for an educational building. For this purpose, six rooms having different orientations, sizes, function and façade configuration were selected from case building, Department of Mechanical Engineering in İzmir Institute of Technology, to evaluate and propose energy efficient lighting design by retrofitting scenarios. The main concern was that none of the rooms had its own proper solution for façade design according to the recommendations for daylighting and energy efficient usage. Input paramaters such as fenestration, light shelves, shading devices, surface colours, lighting fixture types and layouts were studied in scenarios by using daylighting simulation tool, DIALux. In real life application, it is possible to benefit from daylighting effectively and to minimize energy consumption by using intelligent sensors connected to the shading automation systems. This would be the best solution for visual comfort and energy efficiency in buildings. Thus, this study focused on optimum values of the input parameters which would provide such foreknowledge for such systems. In order to obtain energy efficient lighting performance in an educational building, it is important to evaluate the results for retrofitting that will be a guide for designers, architects and researchers.
