Master Thesis Comparatic-Ve Energy Performance Assesment of Hemp-Clay as Building Block Material(01. Izmir Institute of Technology, 2022) Akkurt, Sedat; Durmuş Arsan, Zeynep; Durmuş Arsan, Zeynep; Akkurt, Sedat; 03.09. Department of Materials Science and Engineering; 02.02. Department of Architecture; 03. Faculty of Engineering; 01. Izmir Institute of Technology; 02. Faculty of ArchitectureBio-based and earthen building materials have recently started to be used again in seeking sustainable materials to combat climate change. Hemp-based building materials stand out as energy-efficient materials due to their favorable thermal properties, although they still have unstandardized features that vary by location. This study aims to investigate the thermal properties and energy performance of hemp-clay building blocks which are produced with local hemp and clay in the western Aegean region of Turkey for today and the future, leading up the research on hemp-based building materials in the Mediterranean region. The methodology of the research consists of laboratory experiments on material and building energy simulations via DesignBuilder software. Building block samples were produced with 27 different hemp-clay mixtures and tested using a quick thermal conductivity meter. Subsequently, the thermal performance of selected hemp-clay block was compared with conventional wall infill materials such as hollow clay brick, autoclaved aerated concrete, and lightweight pumice block via simulations of the annual energy consumption of an existing residential building in Izmir. Simulation scenarios were generated keeping wall thickness and U-value as constant for the climate of 2020, 2050, and 2080. Hemp-clay building blocks reduced the heating and cooling demands of the case building by 21% and 14%, respectively in 2020. Their energy performance outperformed the other materials' performances even if the scenario walls have the same U-value as hemp-clay walls in today's and the future's climate conditions. Consequently, the hemp-clay building blocks are apparent as a promising material to be improved in Turkey.Master Thesis Global Diffusion of Green Building Certification Systems (gbcs): a Lead and Lag Markets Model(01. Izmir Institute of Technology, 2021) Kale, Serdar; Kale, Serdar; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyGlobal crises in our planet's sustainability emerged in recent history. Hence, the construction industry, which has the largest share in this situation, have witnessed the accelerated proliferation in the number of Green Building Certification (GBC) systems (such as LEED, BREEAM and Green Star) in the last two decades. GBC systems have received massive attentiveness from academics from numerous disciplines as a reasonable response to its accelerated proliferation. The general concepts described in preceding research endeavours on GBC systems comprise (1) evaluation benchmarks used in rating and weighting, (2) incentives and handicaps for acquiring a GBC system, (3) efficacy of a GBC system, (4) comparison of numerous GBC systems, and (5) systematic reviews of the research and studies. The research presented herein pays particular attention to a relatively disregarded research area on GBC systems: global diffusion behaviours. It conceptualises a GBC system as a product rating service provided in certain nations and employs the Mixed Influence Model to investigate this certification service's cross-national diffusion behaviours. Initially, this model was used to investigate population growth. Thereafter, its application has been widened to explore the diffusion of industrial systems such as goods, services, and innovations. The Mixed Influence model was constructed incorporating data from one of the oldest GBC systems, LEED. The results of the Mixed Influence model reveal the cross-national diffusion behaviours of the GBC systems.
