Disaster as an opportunity: Passive house design for sustainable architecture in Syria post-war
ABSTRACT Catastrophe in Syria has been an prospect to plan a new reality and offer better living conditions. In other words, post-war rebuilding may present a chance for Syria to display unique originality and quality in upcoming construction and conservation. In this reconstruction the problems such as climate change and its social, environmental, economic, and ethical ramifications, which are widely acknowledged as the most severe collection of interlinked issues confronting human society, should be taken into consideration. These issues do not play a crucial role in current Syria reconstruction. Because of this, this study aims to reveal improvement potential for energy efficiency in Syria. Following this aim, the passive house concept has been introduced as a strategy for energy performance of the Syrian reconstruction. Passive houses are defined as buildings which provides thermal comfort with adequate indoor air quality by preheating or pre-cooling fresh air without the need for additional air circulation. In the study, a case study has been selected to reveal the energy performance and payback period on model testing. Evaluation by selecting a representative passive house. This representative case study has been evaluated with different scenarios which report the differences between initial investment and lifetime expenses, focusing on the payback period. In addition to the existing evaluation, two more scenarios, low-energy and passive housing, have been evaluated and compared in each other. The heating, cooling, and primary energy consumption results have been computed and discussed in a comparison for each scenario. Results showed that low energy, and passive housing technologies are applicable in Syria regarding the improvement needed in professional trade workers and materials. Consequently, it has been revealed that, converting to low-energy or passive house design can save up to 205 kWh/m2 annually, reducing CGC -no less than- 88 kgs CO2/m2. The overall benefits would be a reduction of 74-83.9% on cooling energy and a decrease of 45-55% on primary energy demand. Since energy savings represent one for the most Passive House advantages, the energy prices have a large influence on economic viability of Passive House. Overall, the simple payback, based on a rough cost estimate for all measures combined, would be equal to 7.3 years for the passive house and 5.5 years for low-energy, since it really provides a crucial energy efficiency and reduction in Carbon emissions.

The impact of morphology on neighbourhood phenomenon: A comparative analysis of a traditional neighborhood and a gated community
The human is an entity attempting to find a place for himself in the city space based on what is perceived. No matter where people live, they build relationships by interacting with their environment. These relationships are defined by neighborhood bonds inside the physical boundaries of the area, and neighborhood consciousness evolves through time. However today it is apparent that these relationships have been broken in most settlements. When the disintegration have been analyzed, it is noticeable that it advances in parallel with the change in the physical texture of the neighborhood morphology. This raises the question, "What are the components that make a neighborhood a neighborhood?" From past to present, there have been changes in the urban space which also been examined with urban morphology studies. Today, it is feasible to state that there are communities that attempt to preserve their original texture, as well as neighborhoods that may be characterized as gated settlements which were designed with the intention of excluding others. These have a detrimental impact on the morphology of the city with the islands they produce and causes a man-made disaster in the city which damages social relations by human hand. At the same time, it causes a question of the phenomenon of "neighborhood" and "neighborliness". The physical and social differences between the gated community model and the traditional neighborhood have been examined in this study with the analytical framework developed after determining the major criterias which have been defined as safety, sense of belonging and walkability for neighborhood formation and the distinctions between two models have been revealed. Afyon-Bucak Neighborhood has been chosen as a case study for a traditional neighborhood, whereas Ankara-Serhat Neighborhood has been chosen as an example of a contemporary gated community. Keywords: Neighborhood, Gated community, Safety, Sense of belonging, Walkability

Based on this framework, with the help of survey observation and mapping techniques, the main result is to understand the importance of the urban identity and urban regeneration process in the historical city center. In conclusion, the problems and the potential solutions have been recommended for a successful transformation process to protect urban identity/authenticity regarding sustainability, while responding to the requirements of users in terms of attractivity and livability.
Out-of-plane behaviour of masonry wall strengthened with carbon fiber reinforced polymer (CFRP)
The masonry walls are widely used in all over the world, especially in historical buildings. Strengthening of the masonry walls is one of the important issues to investigate for the researchers. There are some methods to improve the masonry walls' in-plane or out-of-plane resistance capacities against static or dynamic loading. Fiber Reinforced Polymers (FRP) application is one of these methods used to increase the bearing capacity of masonry walls. The aim of this study was to examine the effectiveness of Carbon Fiber Reinforced Polymer (CFRP) for strengthening the masonry walls. In the study, the out-of-plane failure mechanism of masonry walls, which is frequently encountered during earthquakes, was discussed. Ten 100 mm x 410 mm x 1200 mm masonry walls were fabricated for experimental study. Solid brick that has the dimensions of 50 mm x 100 mm x 200 mm was used in the production of the masonry walls. For mortar, repair mortar was used for ease of production. Nine of the test specimens were strengthened with carbon fiber reinforced polymer (CFRP). Application form of the CFRP (as strip or full layer) and number of layers were adopted as test parameters. Masonry wall specimens were tested under the effect of bending, applying three-point loading. During the experiments the measurements of load and displacement were taken. The behavior of the masonry walls were assessed in terms of ultimate load, the displacement corresponding to the ultimate load, stiffness, and energy dissipation capacity. According to the results obtained, it is concluded that the strengthened masonry walls with CFRP are quite successful against the out-of-plane collapse mechanism. It is thought that the findings of this study can serve as a guide for engineers and architects that have an interest in strengthening masonry walls.

Design for play: Child-friendly neighborhoods following the culture context and play patterens
Over the past few decades, there has been increasing recognition that the everyday environments of neighborhoods affect a child's brain structure and profoundly impact their health and well-being. However, childhood experiences within the neighborhood have witnessed a substantial transformation increasingly leading to children disappearing from the urban scene and a reduced frequency of children engaging in outdoor activities. This thesis aims to evaluate the child-friendliness of two modern neighborhoods in the city of Homs. In addition, this study examines the perceptions of 6-12-year-old children and their parents to grasp the physical and social-spatial factors of the neighborhood affecting children's usage of their neighborhood. To complete the analysis, this research involved a review of the literature about the child-friendly neighborhood concept and the physical and social-spatial factors influencing children's outdoor activity. It also included semi-structured interviews with parents, field observation, mapping, and an analysis of neighborhood land use in the study area. The morphology analysis reveals that neighborhood morphology has an influence on children's outdoor activities and parents' perceptions of neighborhood. The findings refer that the traditional neighborhood morphology retains essential features for creating a child-friendly environment, contrasting in contemporary neighborhoods. In addition, streets, in old and modern neighborhoods, remain significant spaces for children's recreational activities, emphasizing the need to reimagine streets as play environments. In light of the findings, this study proposes several suggestions for city planners and officials that aim to create neighborhood-scale environments conducive to the health and well-being of future generations of children.
Disaster risk reduction management towards resilient communities in north-west Syria
This study, conducted in Atmeh camp, Syria, addresses the critical need for effective Disaster Risk Reduction Management in the context of North-west Syria, marked by complex and protracted humanitarian crises and heightened vulnerability to natural and man-made disasters. The research aimed to investigate disaster resilience and adaptation among various groups within Atmeh camp community that was established as a result of multiple displacement waves from different war-affected regions across Syria since 2012. In addition, qualitative and quantitative research methods were used in this 2022 field study of a community. The sample included 350 diverse participants who shared experiences with natural catastrophes. This sample's quantitative portion of the research consisted of 38 participants. The study sample was drawn from community members, including Key Informant Interviews: Camp Managers, Mukthars, School Administrations, Community Leaders and members of disaster management committees. The qualitative and quantitative research revealed a lack of proactive disaster preparedness in the community, relying heavily on external assistance during crises. Existing committees and teams, though funded, proved ineffective in fostering community empowerment and resilience. The absence of disaster regulations compounded the challenges. The study suggests enhancing community-led disaster risk reduction efforts, utilizing skilled individuals, experienced leaders, and learning from similar communities. Advocacy, awareness sessions, and inclusive training for vulnerable groups are recommended to build disaster-resilient communities. Addressing poverty and related issues is crucial for fostering community self-efficacy. The study emphasizes the need for improved preparation and recovery strategies in Atmeh camp and the broader district.
Moving from emergency (short-term intervention) to sustainability (long- term intervention) in response to disasters
Rapid and effective interventions are crucial from governments and organizations at different levels, especially within the humanitarian field, in the response to both natural disasters and armed conflicts. In other words, disaster response largely depends on the nature or type of disaster, then duration. The suffering of Syrian IDPs in their tents has continued for many years, despite the presence of many bodies and organizations working on the ground. But it seems that the problem is not the presence of anyone responding to the disaster as much as it relates to the type of this response and the preparation for it before it occurs. Initially conceived as emergency structures, these camps have evolved into semi-permanent settlements, prompting questions about their sustainability. The research problem focuses on the need for an effective response to the protracted humanitarian crisis within internally displaced persons (IDP) camps in Syria. Specifically, the focus is on camps in Dana, Harim, Jarablus, Azaz, and Al Bab. The research strives to explain the reasons behind the apparent lapse in applying disaster risk reduction (DRR) techniques in long-term IDP scenarios. This necessitates a recalibration of humanitarian strategies to address the multifaceted challenges of the protracted conflict and the resiliency of these camps in the face of natural disasters. A structured survey instrument comprising 22 questions was meticulously designed to capture nuanced insights from a representative sample of 350 IDPs residing in Syrian camps. However, only 305 participants in the five camps gave responses to them. The data underwent thorough analysis using SPSS software, employing descriptive and inferential statistical techniques. The findings underscore the paramount importance of the transparent structure of the organizations working on the ground, effective communication channels, meaningful refugee involvement in decision-making processes, establishing capacity-building initiatives, classifying the camps on the ground, and advocacy towards depends on private funds/donations. These factors are essential to cultivating a secure environment for Syrian refugees, facilitating the transition from emergency (short-term intervention) to sustainability (long-term intervention). Keywords: Camps, emergency, long-term, protracted, short-term, tents, vulnerable.
Diyarbakır geleneksel evlerinin kültürel kimliğini mimari oranlar ve mekansal ilişkiler yoluyla keşfetmek
Diyarbakir traditional houses are characterized by ecological design principles that adapt to the local terrain, holding significant cultural, historical, and architectural importance. The literature suggests that these houses symbolize similarity in architectural proportions and spatial relationships with other Turkish traditional houses. However, in Diyarbakir, traditional houses, like those in Syria or Iraq, often lack comprehensive documentation. Therefore, during reconstruction efforts, it becomes necessary to have a clear understanding of the spatial relationships between different components, in addition to determining the architectural proportions. While it may not always be possible to replicate historic homes exactly as they were in historic centers, ensuring the correct spatial relationships and proportions can effectively guide the reconstruction process. This study focuses on exploring the relationship between the cultural and architectural identity of Diyarbakir traditional houses through a two-pronged investigation: proportional analysis and spatial analysis. Proportional analysis unveils a comprehensive design language reflecting the cultural identity of Diyarbakir. Spatial analysis identifies the central courtyard and iwan as shared elements embodying deep social values and adaptability to diverse family needs. In conclusion, the study underscores the profound link between cultural and architectural identity, offering insights for preserving and reconstructing traditional houses. It may also contribute to integrating traditional architectural proportions and spatial relationships into contemporary architecture. This scholarly resource enhances understanding of Diyarbakir's cultural heritage and serves as a reference for extending this approach to studying other traditional buildings in Diyarbakir or other regions. Despite potential variations in results due to construction methods in different regions, the relationship between architecture and cultural identity remains a constant factor.

Applying build back better (BBB) in northern Syria
This study aims to highlight the advantages of applying Build-Back-Better (BBB) process in the northern regions of Syria and specifying the major aspects, which can play a significant role in the positive transformation of Syria and Syrian community. In addition to the destruction and damage caused by the conflict, many buildings have been built without considering safety technical standards. Moreover, the infrastructure of these areas is either missing or very poor. Therefore, defining and assessing these damaged and under-standard buildings are essential, as urgent initial steps for reducing the disaster risks. Refugee camps in that area repeatedly suffer from natural disasters including floods and freezing weather in winter. One of the three applications considered in this study is transforming the big camps in northern Syria into appropriately planned cities. Both the Syrian code of urban planning and AFAD standards for container cities are compared in this study. A modified Syrian code for urban planning is used to re-plan one of the biggest camps, Atmeh Camp, as an example of the first application of the camps into cities. The second application is about improving the urban planning of key cities and towns in northern Syria like Al-Bab and Azaz. The requirements of this application are discussed, and the achievements of the Association of Al-Bab Engineers are listed to illustrate some of the efforts that can facilitate this application. The third application is based on a survey concerning the Syrian refugees in Turkey in specific as it hosts about four million Syrian refugees. The survey investigates the privileges that Syrians enjoy in Turkey and wish to see if they return to Syria. A possible BBB framework is proposed for northern Syria enlightened by the Syrian refugees' experience in Turkey. This application tackles how BBB could encourage the return of Syrian refugees and specifically those in Turkey. The three suggested applications of the BBB principles are aimed as the attempts to rebuild and revive Syria or at least a part of it for now.
