Abstract

Generally, buildings consume around one-third of the world's total energy. Most of the energy in buildings in Indonesia is used by air conditioning systems. One effort to minimize energy waste in the building's air conditioning system is by lowering OTTV (Overall Thermal Transfer Value) to reduce external heat entering the building sheath. The study aims to analyze geometry and WWR (Window to Wall Ratio)’s influence on OTTV and building energy consumption through manual calculation and simulation processes on Autodesk Ecotect Analysis software. This research uses experimental quantitative methods by taking the Bosowa Tower located in Makassar as the research object to serve as a control variable in making alternative building models. The results showed that geometric and WWR variations in buildings were sufficient to affect OTTV values and cooling energy consumption. The smaller the ratio between the length and width of the base and the smaller the percentage of WWR in the building, the smaller the OTTV value and cooling energy consumption of the building. From this study, the most effective combination of geometry and WWR applied to buildings is the combination of 1:1 and WWR 15%.

Abstract

Architecture firms in Makassar City are generally dominated by entities that do not yet have a physical office to reflect their professionalism and credibility. In the context of the city's rapid growth, the need for an office that demonstrates professionalism becomes increasingly crucial. Rental offices are one of the solutions for architectural firms that do not yet have a representative physical office. Still, currently, the rental offices available in Makassar City cannot meet this need, despite its importance. Meanwhile, there are no standardized criteria for the type and size of space requirements of architectural bureau start-ups' rental offices, so research is needed to identify the necessary number of space units and the most dominant space requirements for architectural bureau start-ups in Makassar City. This research aims to identify how many space units and what space needs are most dominantly needed by a beginner architectural bureau. A mixed research method through literature review and questionnaires was used to gain a holistic understanding. The results showed that the priority space required by a start-up architecture firm with a capacity of less than ten people and an area of approximately 34.25 m2 includes a director's room, administrative staff room, principal architect room, and studio room. At the same time, other needs are still considered in the rental office design as shared facilities.
