Performance of bioclimatic design strategies at residential College Buildings in University of Malaya / Adi Ainurzaman Bin Jamaludin
2020Co-Authors: Adi Ainurzaman JamaludinAbstract:Preliminary studies of twelve residential Colleges located in the University of Malaya campus, Kuala Lumpur were conducted to evaluate the effectiveness of their current implementation of bioclimatic design strategies, as well as their performance in terms of electricity usage. It was found that residential College Buildings designed with an internal courtyard and balconies for each room achieve the most efficient electricity use, within a range of between 24 to 33 kWh/m2/year, while other residential College Buildings recorded annual electricity use of between 40 to 125 kWh/m2/year. One of them, 5th residential College (5th RC) was selected for the case study due to its best implementation of bioclimatic design strategies that encourage efficient energy use. Furthermore, its uniform building layout minimises uncontrolled variables in further field investigation and evaluations. The satisfaction and perception surveys show that a majority of respondents at 5th RC are at a comfortable level. This is based on findings from all performance indicators of functional elements, thermal comfort and indoor air quality, as well as, visual comfort and landscape elements. The 5th RC is capable to provide a comfortable living space with indoor temperatures ranging from 28°C to 30°C with 70% to 78% relative humidity. Different locations have different effects on room conditions and higher temperatures were recorded at rooms on the top level of the building compared to rooms at the lower levels. There were no significant differences detected owing to different orientation of rooms which are largely due to the effects of the green landscape. Higher values of daylight intensity were recorded in the corridor compared to the daylight intensity in the rooms which even varies in amount at different areas within the same room. Further analysis show that night ventilation provides better thermal comfort for residents compared to other ventilation options like full-day and daytime ventilation or no ventilation at all. The living behaviour assessment reveals that residents of 5th RC have adapted well to maintain the comfort level in their rooms. Only light activities were conducted in the rooms which reduces the metabolic heat production. Ceiling fans were fully utilized at the maximum speed of five for maintaining air circulation in the rooms where the operable windows are closed most of the time due to the safety issues. Light clothing was worn at most times, especially on sunny days. In fulfilling the need for privacy, curtains have been overused and leading to the use of artificial lighting. The study concludes, residential College Buildings that implement the appropriate bioclimatic design strategies, particularly to address natural ventilation and daylighting issues tend to achieve a desired comfort level and efficient electricity usage. With a well-planned design improvement, better results can be achieved without sacrificing the needs and comfort level of the residents.

performance of electricity usage at residential College Buildings in the university of malaya campus
Energy for Sustainable Development, 2017Co-Authors: Adi Ainurzaman Jamaludin, Noor Zalina Mahmood, Zul IlhamAbstract:Abstract A critical analysis of characteristic and building design was done through scaled drawing and observation from a site visit of twelve residential College Buildings in the University of Malaya campus. The elements of passive mode were implemented as matrixes or criteria for the recent practice of bioclimatic design strategies. The performance of electricity usage was audited based on the Energy Efficiency Index (EEI) in kWh/m 2 /year unit of each residential College building for the duration of nine years. As a result, the average electricity usage varied from 24 to 120 kWh/m 2 /year. The residential Colleges that have appropriate practices of passive mode particularly internal courtyard and balconies that encourage daylighting and natural ventilation were found to achieve a desired efficient use of electricity, in the range of 24 to 34 kWh/m 2 /year.

Energy performance: A comparison of four different multi-residential building designs and forms in the equatorial region
2011 IEEE Conference on Clean Energy and Technology (CET), 2011Co-Authors: Adi Ainurzaman Jamaludin, Ati Rosemary Mohd Ariffin, Nila Inangda, Hazreena HusseinAbstract:Building sector has been identified as a major energy consumer with nearly half of the world's energy used is associated with providing environmental conditioning in Buildings. Approximately, two third of this is for heating, cooling and mechanical ventilation. Therefore, there is a need for optimizing the building design which collaborates with surrounding environment in enhances the energy conservation programme. Energy consumption evaluation and audits for Buildings is the most important step that can contribute to energy conservation. As preliminary studies to this research, four low-rise residential College Buildings with specific layout were selected in finding the relationship between green/passive building strategies and energy performance. The study initial approach was to critically analyse the design of the selected Buildings through scaled drawings and site visits. Comparison of the two were carefully made to obtain current and post renovation conditions and surroundings as most of the drawings were drawn 30 to 40 years back. The elements of bioclimatic design were implemented as matrixes or criteria, particularly on natural ventilation and day lighting. Then, the energy performance was crucially audited to find out Building Energy Performance (BEP) acknowledged as energy use per unit floor area, and Energy Efficiency Index (EEI) to elaborate the kWh/m2/year of each residential College for five years duration. As initial findings, the implementations of appropriate green building strategies is able to provide positive impacts to the overall energy performance of the residential Colleges.

energy performance of three residential College Buildings in university of malaya campus kuala lumpur
Journal of Design and the Built Environment, 2011Co-Authors: Adi Ainurzaman Jamaludin, Nila Inangda, Ati Rosemary Mohdariffin, Hazreena HusseinAbstract:Three residential Collegeslocated in Kuala Lumpur, Malaysia, were selected for energy performance analysis in regards to its implementation of bioclimatic design strategies. Specifically, passive design strategies on daylighting and natural ventilation were examined. In Malaysia, the residential College or hostel is a multi-residential building providing accommodation to university students. The three residential Colleges in this study, namely C1, C2 and C3, were built in different years with different designs and forms, particularly with regards to enclosure and facade design, solar control devices, passive daylight concepts, and natural ventilation strategies. The building designswere carefully studied and an electric consumption analysis was carried out in each residential College. This study revealed that the wide-scale implementation of bioclimatic design strategies in College C2 help reduced the annual energy consumption. The building bioclimatic design features that are accountable to reduce energy consumption are the internal courtyard and balconies on each unit of floor area, as shown in C3.Results from this study highly recommend internal courtyard and balcony building combinationfor multi residential building design, especially in tropical urban regions.

architecture academe College Buildings in new england before 1860
Planning for higher education, 2012Co-Authors: David A ThurmanAbstract:Architecture & Academe: College Buildings in New England before 1860 by Bryant F. Tolles, Jr. University Press of New England 2011 217 pages ISBN: 978-1-58465-891-7 [ILLUSTRATION OMITTED] The trustworthy Mr. Tolles lets history, rather than his own speculations, speak for these beautiful campuses, each College basking in its own unique glow. His effort stacks up as dependably and timelessly as the Old Brick Row. The task of building and sustaining America's first higher education institutions could be a serious and difficult job. The lack of trained architects, limited funding, an ongoing threat of fire, and (at times) unruly students all posed challenges. In this book, Bryant F. Tolles, emeritus professor at the University of Delaware, applies a lifetime of experience to the task of documenting the early architecture and campus development of New England's higher education institutions. The result is a well-written history of pre-civil war campus Buildings that draws heavily on the records of individual Colleges and other archival sources. Mr. Tolles' passion is borne of a career focused on the architecture of New England that includes teaching, authoring books on regional architecture, serving in professional and leadership roles for historical societies and museums, and a desire to further develop his doctoral dissertation on a similar topic. Accordingly, he works in a deliberate way, going campus by campus through New England, capably gathering the many facts and exhibits describing each building project and assessing its role in campus development. The book's first section on the Colonial period begins with chapters on Harvard and Yale, then Brown and Dartmouth, pairing campuses in logical groups. This is followed by a second section on the period between the Revolution and the Civil War, in which he continues the method of grouping campuses, this time by state, including Williams and Bowdoin (Massachusetts); the University of Vermont, Middlebury, and Norwich (Vermont); Amherst, Holy Cross, and Tufts (Massachusetts, again); Trinity and Wesleyan (Connecticut); and Colby and Bates (Maine). The benefit of this approach is that it identifies key precedents during the Colonial period that provide a starting point for later campus discussions. The facts surrounding each building's history and role in campus development make up the heart of each chapter. For instance, University Hall (1815-15) at Harvard is a typically well-organized example. The author first characterizes the building in a general way as "one of Harvard's most famous and architecturally meritorious structures" (p. 18) and documents Charles Bulfinch's planning and design intentions (including Bulfinch's early campus layout diagram). There is a detailed description of the building's striking architectural features (a three-unit composition, Federal-style character, Ionic capitals, fully articulated entablature); the building's multipurpose functions (president's office, six classrooms, chapel, dining hall); its materials (Chelmsford granite); and its cost at the time ($65,000). The expert use of building terminology supports a well-reasoned architectural critique, a method the author applies to other campus Buildings and one that yields a complete portrait of the early campus. The persistent use of this approach in other campus profiles helps the author identify shared interests and information exchanges, a primary focus of the book. As the author notes in a key introduction, "Throughout the entire region, Colleges and universities participated in active cultural transfer, sharing evolving concepts of living and learning within continually changing physical environments" (p. 9). A featured example of this exchange is Yale's admirable Old Brick Row, which the author champions time and again as an inspiration to campuses in the region. He traces the spread of its influence to a surprising number of the campuses in the book. …
