Evaluation of sustainable building design and its associated management tools in design offices : case of Iran
(2020-05-29) Rizi, Rana Abdollahi; Karahan, Ebru; Karahan, Ebru; Tekçe, Işılay Akkoyun; Yazıcı, S.; Department of Architecture; Rizi, Rana Abdollahi
As the importance of sustainable development gained momentum, the extent to which it should be implemented remained a matter of concern. Among all, buildings are among the remarkable results of human activities that have a substantial impact on the environment, from construction to demolition. On the other hand, sustainable buildings provide ways to reduce the harshness of buildings’ impacts on the environment and help to promote a sustainable way of living and to achieve sustainable development targets. The fact that in each region, “Sustainable Development” needs to follow regional conditions led this research to choose a case study (Iran) to evaluate Sustainable Building Design (SBD). The thesis aims to study the Iranian design firms who have showed their will to follow SBD guidelines and to analyze the drivers justifying their interests. Regarding the aim of the research, the following questions raised: i) To what extent have SBD and its associated management techniques and tools implemented in building design firms? ii) What are the barriers and success factors in implementing sustainable building design management and its associated tools? iii) What are the influencing factors for implementing SBD? iv) How much acceptance, readiness, and willingness exist among the firms regarding Sustainable Building Design Management (SBDM) and its associated tools? v) To what extent are the issues mentioned above implemented in the case of Iran? Understanding sustainable development would help to make decisions to improve the procedure for implementing sustainability in building design. It would also suggest a way to mitigate and eliminate problems and obstacles in adopting sustainable principles through management techniques. In the thesis, first, a literature review is conducted. Secondly, a survey was built on the inspiration of the literature review. Following the survey formation, interviews conducted at thirteen sustainable building design firms in Tehran, Iran’s capital. Finally, the results showed that there were insufficiencies in the education and regulation system regarding SBD in Iran. In addition, barriers and obstacles to implementing SBD, SBD Management (SBDM), and SBD Management Tools (SBDMT) were revealed from the perspective of participating firms. The training and acceptance of SBD, SBDM, and SBDMT were evaluated among firms. Finally, the recommendations were based on literature and survey results.

Occupants' migration in residential buildings towards comfort and energy efficiency (case of traditional residential architecture in Iran)
(Springer, 2021-03-17) Rizi, Rana Abdollahi; Rizi, Rana Abdollahi
Recently, the role of occupants' behaviors on building energy efficiency has been much more taken into account. Occupants' migration on a building scale is a phrase on which this article focuses as one of the best occupants' responses to the climate condition for comfort and energy efficiency in traditional architecture. This paper attempts to step towards recovering the role of traditional adaptive occupants in contemporary buildings for comfort and energy efficiency. To this end, this study aimed to achieve the following objectives: (1) to summarize the socio-environmental and psychological elements of traditional housing that help occupants migrate in a building for their needs, comfort, and energy efficiency. (2) to reveal the interrelated factors affecting occupants' migration in building scale for comfort and energy efficiency. (3) to present types of occupant migration in buildings for comfort and energy efficiency. In order to achieve the objectives of this study, first, a literature review was conducted on the socio-environmental and psychological elements of traditional housing that help occupants migrate in a building for their needs, comfort, and energy efficiency. Also, the interrelated factors affecting occupants' migration in buildings and the types of occupant migration in building for comfort and energy efficiency were considered via both content analysis of available literature, and field survey methodologies. Besides, a comparison is made between the traditional style of housing and migration and the new style. Finally, the results showed that psychological, environmental, and social factors not only motivated people to move around to survive; achieve more thermal, visual, and mental comfort; but also contributed to more environmentally friendly spaces, which ultimately provide people with health, well-being, and energy efficiency. These movements and their associated contributing architectural elements were interrelated and affected one another in mutual respect. People underwent these movements in vertical and horizontal directions for their needs and energy efficiency because the space potentials provided incentives for them to do so.

A user detective adaptive facade towards improving visual and thermal comfort
(Elsevier, 2021-01) Rizi, Rana Abdollahi; Eltaweel, A.; Rizi, Rana Abdollahi
Adaptive skins and, in particular, adaptive façade play a significant role in the future of environmentally friendly spaces. Meanwhile, occupants' involvement in the process of adaptive façade design and operation is essential to guarantee its usefulness. This study aimed to address two less-attended issues in current literature in the process of adaptive facade design. First, a few research attempted to include users during adaptive facade design processes. Second, less attention is given to the simultaneous optimization of both visual and thermal comfort during adaptive façade design. Given these, an innovative methodology is developed to involve occupant's/s' position inside space while considering comfort issues. Another novelty of this study is the geometry associated with double-sided material. Improvement in visual comfort quantity and heat gain are the objectives of this study for the position of occupant/s. Parametric simulation and Genetic algorithm optimization have been used to carry out this research. On average, there was a 76% improvement in visual comfort of the occupant throughout the year by the proposed system compared to the conventional shading state. Besides, there was in average 60% improvement for the heat gain improvement via the proposed adaptive facade compared to the conventional shading state when the objective function was set to increase the heat gain. Also, when the objective function is set to decrease heat gain, a 59% improvement has been achieved compared to no shading state. Finally, the proposed adaptive facade and the innovative method of design can be used to address the position of the user/s inside space to enhance visual and thermal comfort.
