The Energy Use and Living Behavior in Urban Retrofit Vernacular Architecture

Joglo House, which is an iconic symbol of Javanese architecture has been traded and inherited by modern people, who have made modifications to suit their lifestyle. This paper examines the changes made to the Joglo house, which was modernized and adapted to the needs of its users. This research also analyzes the changes in energy use resulting from these modifications. This research involved measurements and documentation of the Joglo house to record the changes made by its users. Direct interviews with the users were also conducted to gather information on their habits and activities, as well as the atmospheric conditions on the site. The collected data was analysed to determine the building's condition and energy usage. This research documented the modifications made to the Joglo house, which included the installation of modern appliances and the addition of new rooms. These modifications increased energy usage, with the house's energy consumption higher than before. Joglo houses in the pre-modern period only uses firewood as a source of energy for daily living, making no direct energy usage such as electricity and gas. The rise of electrical energy usage till this day has reached a high number of 4.4 Kilowatt per month. The research also revealed the habits and activities of the users, which were found to have a significant impact on energy consumption. This paper is expected to be a valuable resources for future research in architecture and lifestyle. The result of this research shows the differences in area of activity and thermal comfort.
