Visual comfort is important for the building occupants’ wellbeing. Visual comfort can be filled with natural lighting (daylighting) and artificial lighting. Efforts to optimize natural lighting can be achieved through façade design, and percentage area of window. However, the problem of the visual comfort is high light intensity and glare at some places. Light shelf is a passive strategy to minimize glare, expanding the area of daylighting and increase the time that meet the visual comfort. This paper discusses the light shelf design that can fulfill the optimal visual comfort and lighting energy savings for an office space with the case studies Prasetiya Mulya office. The methodology of research used is quantitative research with simulation modeling (DIALUX 4.13, 2016). Through following steps; (1) Making a model of office space based on case studies: Prasetiya Mulya office, Jakarta; (2). Making three models with different light shelf dimension; (3) Simulating and analyzing the light intensity value for each model that meet office visual comfort standard: 350 Lux (Indonesia National Standard, 2010), glare value and optimal energy saving. The result show that light shelf design can meet optimal visual comfort and save energy for artificial lighting. With right design of light shelves, we can expand daylighting area that meet visual comfort, minimize glare and increasing energy saving in the office.
