Item type:Publication, The manipulation of architectural elements to achieve interior thermal comfort: A case of residential buildings in Bangkok(2013-01-01); Sahachaisaeree, NopadonThe application of combined remedial methods that enhances energy efficiency for cooling of buildings depends on efficient interactive effects to provide occupants with optimal living comfort. This paper aims to utilize small-detached houses in Bangkok to examine the best manipulation of architectural elements that can supply appropriate thermal environment in a Thai residential context, and proposes guidelines for passive design. Environmental factors such as temperature and air movement in a tropical climate were tested using computer modelling. Study results potentially propose the guideline for the architectural design process as well as recommend an interior environmental management model for post-occupancy indoor thermal improvement. The findings indicate that the proportion of a sub-division of internal space and open utility spaces are crucial ventilation factors to reduce thermal inertia for building cooling. Additionally, the results point to two critical wind speeds and the best type of voids that respond to wind direction. © Common Ground, Nuchnapang Keonil, Nopadol Sahachaisaeree, All Rights Reserved. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Energy-efficient management modeling towards interior thermal comfort: An architectural element manipulating case study on small detached houses in Bangkok(2010-01-01); Sahachaisaeree, NopadonThis paper investigates the thermal perceptual aspect from daily activities. The research uses the cases of small detached houses in Bangkok to examine the best manipulation of architectural elements to optimally provide thermal comfort in the Thai living context applying a multi-facet research methodology. Two aspects of design manipulation - the spatial arrangements and buildings feature - are examined towards the optimization modeling. The level of perceived comfort obtained from data analysis is used as input in the modeling program to be tested to obtain the model of comfort optimization strategy and to set the guideline of passive design for tropical climate. © 2010 Elsevier Ltd.

Item type:Publication, Generative Design Process for Alternative Creation of Architectural Design: Application of Willis Tower Shading Analysis Case Study(2023-01-01); ; Generative design is a type of popular computational design providing a simple alternative design that is important instance to architectural design. This study aimed to examine generative design process to better understanding, and building an instruction set by repeat experiment methodology through case study. Willis Tower Shading Analysis was applied using variables that cause differences design options of nine sorted tubes alternate automation tower of 30-, 60- and 90-meters height. Forty-five design options were generated from generative design process, selected variables used in design options including building area, shadow area, neighbor building overshadowing and park overshadowing. It was found that generative design was a quick, modest and practical process that was easy for appropriate analysis. Additionally, input data and instruction for generating multiple output design options could be set for selecting of an option and the process could be reversed for designers required options. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A Systematic Review of Applications of Generative Design Methods for Energy Efficiency in BuildingsEnergy efficiency is a principle of architectural design that reduces environmental impact. Generative design can offer alternative options to improve energy efficiency in buildings, but significant gaps exist in the application due to accessing complex knowledge. This study aimed to explore publications on generative design and energy efficiency in buildings and identify generative methods for energy efficiency topics. This study conducted a systematic review using the PRISMA methodology in December 2023 by searching publications from databases including Scopus, Google Scholar, and Thai Journals Online. Descriptive analysis examined 34 articles, showing the publication year, source, and citations. Comparative qualitative and descriptive analysis identified generative methods. Publications are increasing over time, and further growth is expected related to the accessibility of computational design and practical applications. Tools and frameworks demonstrated reduced energy usage compared to prototypes or traditional design approaches. The most studied is thermal performance, which was reduced by 28%. Energy performance achieved up to a 23.30% reduction, followed by others and daylighting. In addition to single-topic studies, there are also studies with multiple topics. Evolutionary algorithms are standard. Parametric search strategies have increased. Exploration reveals rule-based and mixed methods. Machine learning and AI garner attention. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Energy-efficient management modelling towards interior thermal comfort: A case of composite dwelling features manipulation in Bangkok(2011-12-01); Sahachaisaeree, NopadonApplicability of combined remedial methods for passive cooling depends much upon the most efficient interaction effect among them to provide occupants an optimal living thermal comfort. This research thus aims to utilize the small detached house in Bangkok as a case study to examine the best manipulation of architectural elements to provide an optimal thermal comfort in the Thai living context, and to propose a guideline for thermal comfort design. Information regarding microclimate of Bangkok Metropolis is retrieved from the meteorology office to be utilized as ambient input in the computer modelling. Several design factors - temperature, humidity, and air movement - are then tested to obtain the final model of comfort optimization strategy. Test result indicates that the best type of voids responding to the 90° wind direction is large openings with relatively smaller intake, which configuration is able to increase the interior wind speed up to 1.05 m/s. The optimal type of opening for diagonal wind direction, however, has been the medium size opening with zigzag interior void, which could obtain the interior wind velocity up to 1.5 m/s. The effective range of summer day-time temperature for passive cooling in Bangkok is limited to only 30 - 33°C.
