In Indonesia, the building sector is responsible for 50% of the total energy consumption from all sectors and more than 70% of overall electricity consumption. The highest energy loads of the office sector is around 57% of the building and 50% of the energy loads on the building belongs to the air conditioning. This study attempted to optimize planning and design, especially through controlling the external energy loads (heating) that enter the building envelope (wall and vents). Case study was conducted in Makassar at Residential and Building Development Information Center (PIP2B Building). The method utilized OTTV (Overall Thermal Transfer Value) consisting of planning and building design analysis especially accounting for heat energy entering the building through windows and vents of the building. According to the Ministry Public works regarding OTTV, the standard for building the energy conservation was 45 W/m 2 but the standar was increased to 30-35 W/m 2 . From the results of OTTV calculations, an external energy load entered into the building through the building envelope (walls and windows). The result of OTTV calculation shows that some sides of building have an increased amount of energy that went through the wider windows. Through optimizing and planning the windows area, thedecreasing external energy (heat energy) that entered from the outside is encouraged.
