    An Approach for Developing Sensitive Design Parameter Guidelines To Reduce the Energy Requirements of Low-Rise Apartment Buildings
    (Elsevier Ltd., 2012) Yıldız, Yusuf; Korkmaz, Koray; Göksal Özbalta, Türkan; Durmuş Arsan, Zeynep
    High levels of energy consumption in residential buildings and global warming are important issues. Thus the energy performance of buildings should be improved in the early stages of design. This article describes an approach for developing guidelines on sensitive and robust design parameters for the present, the 2020s, the 2050s and the 2080s. Such guidelines can help architects to design low-rise apartment buildings that require less energy for various purposes, such as heating or cooling. The article consists of a general literature review, interviews with architects, the generation of case-specific information and a mock-up presentation and a meeting with professionals. An example guideline that aims to reduce annual cooling energy loads under global warming in low-rise apartment buildings located in hot-humid climates is presented to demonstrate how the proposed approach can be applied. For this guideline, case-specific information was generated, and a global sensitivity analysis based on Monte Carlo Analysis and the Latin Hypercube Sampling technique was performed. The results show that the suggested approach is feasible and could be used to provide helpful information to architects during the design of low-rise apartment buildings with high energy performance. The most sensitive design parameters that affect annual cooling energy loads in low-rise apartment buildings were natural ventilation, window area, and the solar heat-gain coefficient (SHGC) of the glazing. The results are relevant for the present, the 2020s, the 2050s and the 2080s.

    Identification of the Building Parameters That Influence Heating and Cooling Energy Loads for Apartment Buildings in Hot-Humid Climates
    (Elsevier Ltd., 2011) Yıldız, Yusuf; Durmuş Arsan, Zeynep
    Identifying the building parameters that significantly impact energy performance is an important step for enabling the reduction of the heating and cooling energy loads of apartment buildings in the design stage. Implementing passive design techniques for these buildings is not a simple task in most dense cities; their energy performance usually depends on uncertainties in the local climate and many building parameters, such as window size, zone height, and features of materials. For this paper, a sensitivity analysis was performed to determine the most significant parameters for buildings in hot-humid climates by considering the design of an existing apartment building in Izmir, Turkey. The Monte Carlo method is selected for sensitivity and uncertainty analyses with the Latin hypercube sampling (LHC) technique. The results show that the sensitivity of parameters in apartment buildings varies based on the purpose of the energy loads and locations in the building, such as the ground, intermediate, and top floors. In addition, the total window area, the heat transfer coefficient (U) and the solar heat gain coefficient (SHGC) of the glazing based on the orientation have the most considerable influence on the energy performance of apartment buildings in hot-humid climates.

    Research Into Practice: Malatya Solar Housing
    (Emerald Group Publishing Ltd., 2010) Okutucu, Fikret; Koçhan, Ahmet; Yıldız, Yusuf; Öymen Gür, Şengül
    Purpose: The purpose of this research is to discover the underlying reasons for the failure of solar energy architecture in Turkey in order to be able suggest methods of improving it in Turkey and worldwide. Design/methodology/approach: The methodology employed in this research is on-site observations of Turkish solar houses built with respect to the details of their application, and depiction of heat gains provided with applied solar measures, and to compare them with an ideal gauge to determine the deficiencies involved in applications. Findings: The investigations discovered that various buildings under consideration share several errors. In order of importance, these items are: faulty applications, erroneous choice of methods and lack of precautions in the summer. Practical implications: The practical implications of the study are that measures must be taken to prevent heat loss during winter nights; outer walls with a resistance to heat transmission of u=1 W/m2K would have been preferred rather than ordinary old-fashioned Trombe walls; in order to prevent overheating the surfaces of the sunspaces, Trombe walls and air collectors contacting the outer environment need to be made movable or pliable to avoid sinking of heated air into the sunspace. Social implications: The social implication of the study is that only continued exploration into solar energy use via exemplary practice may encourage adoption of these systems by society itself. Originality/value: The value of the research resides in translating knowledge gained from previous solar projects into design aspects which are expected to avoid these errors and deficiencies, demonstrated herein through Malatya solar housing, from which everyone involved in passive solar house design may benefit. © Emerald Group Publishing Limited.
