    Impact of Thermal Mass for Future Energy Consumption: Case Study in Adobe House
    (Inderscience Enterprises, 2019) Durmuş Arsan, Zeynep; Durmuş Arsan, Zeynep; Yöney, Ekin Gamze; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    This paper examines thermal mass quality of building envelope as passive preventive phenomena for future energy consumption. It questions how much and what type of thermal mass is required for decreasing energy consumption according to future climate change. Summer energy performance of adobe house in Konya, Turkey is studied in terms of thermal mass characteristic by using dynamic simulation software. Measured and predicted microclimate data for 2017 and 2050s are used to compare passive impact of wall material choices, i.e. adobe, limestone, vertical hollow brick and volume of wall without night-time ventilation. In conclusion, the study reveals that thermal mass with lower density and thinner materials show higher energy performance for summers. Energy consumption is minimum with vertical hollow brick wall in 50 cm for 2017 and 30 cm for 2050s. It is deduced that thermal conductivity will still have higher impact than thermal mass on energy consumption.

    An Evaluation Methodology Proposal for Building Envelopes Containing Phase Change Materials: the Case of a Flat Roof in Turkey’s Climate Zones
    (Taylor and Francis Ltd., 2017) Tokuç, Ayça; Başaran, Tahsin; Başaran, Tahsin; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    Phase change materials (PCMs) can be used to enhance the thermal energy storage capacity of a building element to improve indoor thermal comfort conditions and decrease energy usage, yet these effects need to be carefully analysed to achieve the desired benefits. This paper proposes an evaluation methodology for building envelopes: first, a numerical computational fluid dynamics model is validated by experimental work; then, time-dependent simulations are used to analyse monthly energy requirements and heat flux. A sample flat roof is evaluated in terms of required cooling load with and without PCM in Turkey’s climate zones. Graphical phase change representations and heat flux results were used to evaluate the cooling load reduction in addition to the effects of PCM type and PCM amount and the necessity for night cooling. In conclusion, the methodology is flexible and can be utilized to evaluate the building element for various parameters.
