Title of thesis Thermal comfort and energy studies in multi-storey office buildings in Jakarta, Indonesia
(Ph D thesis, University of Sheffield, UK)
Abstract One of the objectives of designing a building is to provide thermal comfort conditions for the building's occupants while at the same time minimising building energy consumption. A field study of thermal comfort and a study of building energy consumption have been carried out in the capital city of Jakarta, Indonesia. A number of office workers, working in seven different multi-storey office buildings participated in the comfort study. While at the same time, records of electricity (energy) consumption of the seven buildings have been taken.
This comfort study aims to establish the neutral temperature and comfort range of workers engaging light office work in multi-storey office buildings in Jakarta. This study also attemps to assess some variables, such as, age, gender, fatness, etc., which may affect the state of people's comfort. Results from this study are being compared to the results of other previous studies. By using results of this study, assessments have been made to those of Universal (Static) Model of Fanger and the Adaptive Model of Humphreys, Nicol and Auliciems, towards their applicability to be used in Indonesia, Jakarta in particular.
The building energy's study aims to see how much the difference of the energy consumption between naturally ventilated, hybrid and air conditioned buildings is. Some analyses have been made into the possible effect of glazing walls and orientation on building's energy consumption.
By using the result of workers' comfort temperature and data of building energy consumption, strategies to minimise building energy consumption without sacrificing thermal comfort are proposed for Indonesia, particularly the regions which have similar climate to Jakarta.
