China has become one of the world’s economic engines. One major driving force is the rapid urbanization. Such fast development results in resource and energy depletion, pollution and environmental deterioration. The government has recently endorsed green buildings and urged ministries to work out a national action plan. It is predicted that green building will be the next big thing in China. But before importing any foreign green technology and green designs, is there something to be learned from the Chinese ancestors? In the long history of China, the Chinese have always employed a system of construction with the influences of geography, climate, culture, philosophy, economy and politics deeply rooted in China, making the Chinese traditional architecture distinct. Embedded in the formation of the city, siheyuan 四合院, the courtyard house in Beijing was one exceptional dwelling example that inherited the quintessence of the thousand years of building experiences and knowledge of the ancestors. This traditional urban type not only celebrated the rich and unique cultural heritage of China, it also played an important role in maximizing the natural forces to create a pleasant and comfortable environment for living. Population growth, political and economic reforms over time however have drastically changed the fate of this historical heritage. Especially under the pressure of the fast development and economic boom after the introduction of the Open Door Policy in 1978, the traditional courtyards were the first to be demolished due to the lack of modern facilities and the inability to accommodate the growing population. They were often replaced by apartment blocks and high-rise towers – imported types based on planning regulations developed in the West, outside the cultural and environmental milieu of Beijing. As a result, the city is now filled with many energy intensive buildings that eat away both the “city’s essence” and the valuable natural resources. With the current policy and ambition of China, the teardown courtyard sites within the old city wall that are still waiting for development offer the potential to address the remediation and reinterpretation of the traditional typology in a contemporary city. The thesis investigates the essences of the traditional courtyard house and explores the way to apply such qualities to the design of a new courtyard typology in contemporary Beijing. The proposal anticipates a holistic approach on both environmental, social, cultural and economic level, so as to carry out preservation that manifests in experience rather than physical restoration, and to create a project that is truly sustainable.

Historical area is the unique place to a certain context because it contains the most valuable culture on the site and also keeps recording its history. While the increasing pressure from developing tourism and booming population seriously impacts the old site resulting in culture lost. This thesis investigates a typical historical area in Xi’an in a logical process. The process starts with analysis from local fabric as urban scale to living unit as family scale to make a clear view on local culture lost. According to the context, set up appropriate criteria to select typical site to make sure the solution can be well integrated into similar scenario. Then, based on the analysis, generate possible conceptual responses. Finally, design from a modular unit, to courtyard space and to the final block prospect, and make sure the final solution in every step could not only solve the problems, but also accommodate the local life style. The whole design process appropriately integrates the concept of shared space in dealing with the overload urban and living density. The application of the phasing study makes the whole research and design process more sustainable and feasible.

Dans les dernières décennies, les changements morphologiques des maisons iraniennes, l’arrivage de l'éclairage artificiel et le manque de connaissance suffisante de la valeur de la lumière du jour pour le bien-être des occupants ont résulté une diminution de l'utilisation de la lumière du jour dans les habitations iraniennes contemporaines. En conséquence, le niveau du bien-être des occupants a décru ce qui peut être corrélée avec la diminution de l'utilisation de la lumière du jour. Considérant l'architecture traditionnelle iranienne et l'importance de la lumière du jour dans les habitations traditionnelles, cette recherche étudie l’utilisation de la lumière du jour dans les habitations traditionnelles et explore comment extrapoler ces techniques dans les maisons contemporaines pourrait augmenter l'utilisation de la lumière du jour et par conséquence améliorer le bien-être des occupants. Une revue de littérature, une enquête des experts iraniens et une étude de cas des maisons à cour traditionnelles à la ville de Kashan ont permis de recueillir les données nécessaires pour cette recherche. De par le contexte de recherche, la ville de Kashan a été choisie particulièrement grâce à sa texture historique intacte. L’analyse de la lumière du jour a été faite par un logiciel de simulation pour trois maisons à cour de la ville de Kashan ayant les mêmes caractéristiques de salon d’hiver. Cette étude se concentre sur l’analyse de la lumière du jour dans les salons d'hiver du fait de la priorité obtenue de l'enquête des experts et de la revue de littérature. Les résultats de cette recherche montrent que l’extrapolation des techniques traditionnelles de l'utilisation de lumière du jour dans les habitations modernes peut être considéré comme une option de conception alternative. Cette dernière peut optimiser l'utilisation de lumière du jour et par conséquence améliorer le bien-être des occupants. L'approche utilisée dans cette recherche a fourni une occasion d’étudier l'architecture du passé et d’évaluer plus précisément son importance. Cette recherche contribue ainsi à définir un modèle en tirant les leçons du passé pour résoudre les problèmes actuels. / In the past several decades, the morphological changes of Iranian houses, the advent of artificial lighting and the lack of knowledge about the value of daylight on occupants’ well-being have caused a decrease in the use of daylight in contemporary Iranian dwellings. As a consequence, there was a reduction in occupants' well-being that may be correlated with the reduced use of daylight. Considering Iranian traditional architecture and the significance of daylight in traditional dwellings, this research has studied using daylight in traditional dwellings and has explored how extrapolating these techniques into contemporary houses might increase the use of daylight and consequently to enhance occupants’ well-being. The required data for this research were collected through literature review, the survey of Iranian experts and the case study of traditional courtyard houses in Kashan city. Kashan city was selected as the context of this research mainly because of its pure historic texture. Amongst the traditional courtyards of Kashan city, three traditional courtyard houses were chosen according to the same features of their winter living rooms and analyzed by daylight simulation software in the worst-case design scenario. The winter living rooms were selected as the focus area based on the extracted results of the survey of Iranian experts and literature review. According to the results that were extracted from this research, it was clarified that extrapolating the traditional techniques of using daylight into modern dwellings can be considered as a design option to optimize the use of daylight and as a result to enhance occupants’ well-being. The approach utilized in this research has provided an opportunity for studying the past architecture more precisely and evaluating its significance. Thus, this research contributes to define a pattern by learning from the past in order to solve the current problems.
