In the aftermath of natural disasters, providing temporary housing to displaced people is essential to alleviate human suffering. However, in some cases, the chosen post-disaster temporary housing strategy may not be suitable for the local conditions, which can worsen the negative impacts, particularly when decision-makers need to change their original plan due to the uncertainty of post-disaster conditions. As most temporary housing design strategies have their weaknesses, the best approach is the one that matches the specific circumstances of each scenario. This thesis proposes design strategies, including prefabricated and modular units, foldable units, upgradable units, grid and linear expansion, and passive energy units, to determine the most appropriate policy to minimize conflicts between local requirements and temporary housing characteristics while maximizing the comfort and sustainability of temporary housing design. The strategies were analyzed based on their strength and weaknesses by following the previous research, and their implementation possibilities on recently occurred natural disasters, e.g., Turkey's earthquake in 2023, were also evaluated. It was found that all strategies except for grid and linear expansion might be suitable for the studied natural disaster.

This research addresses the challenge of integrating ecodesign tools into the digital media industry to reduce the environmental footprint of digital products. Despite increasing awareness of sustainability, many digital media experts struggle to adopt these tools practically. This study investigates experts’ perception of the usefulness and ease of use of ecodesign tools and explores influences on their user experience. The research included two phases: a survey and a user study. The survey involved N=93 digital media experts in Europe and evaluated the perceived ease of use and usefulness of ecodesign tools utilizing the Technology Acceptance Model. It revealed the IBM Checklist for Sustainability and the Sustainable Web Design Guidelines as the most useful and easy to use ecodesign tools. These tools were then examined in a one-week user study, involving N=12 digital media experts. This phase included a diary study and user experience questionnaire. Results indicate that practical guidance, clear understanding, efficiency, trustworthiness, motivation, and innovation influence user experience. While sustainability awareness is rising, integrating ecodesign tools into daily workflows remains challenging for some experts. Comprehensive training and guided integration are needed to address these challenges. Ecodesign tools should fit diverse user needs, enhancing relevance and usability across various roles. Incorporating customizable features, clear guidance, interactive learning resources, and alignment with industry standards better support digital media experts and enhance their user experience. This research highlights the importance of ongoing development and refinement of ecodesign tools within the digital media industry.
