In general, the NZEB potential is 47% to replace electricity supply from Grid/PLN. 1. Introduction At the current condition when the issue of energy security and environmental sustainability become a concern of many countries [1,2,3,4], buildings sector are important as they could create significant impacts on its. In Indonesia building sector consume of the primary energy almost 20% [5] This study aims to make designs for commercial buildings especially existing high-rise buildings to be as efficient as possible in energy use by retrofitting to reduce energy consumption and employing Renewable Energy Sources (RES) by utilizing the potential building heights and cooling water systems to be utilized as micro hydro plant and the application of Building Integrated Photovoltaic (BIPV) on roofs and building facades. This research uses the concept of the Net Zero Energy Building (NZEB) which has several definitions for example according European Union through Energy performance of buildings directive (EPBD) states that "nearly net zero energy buildings mean buildings with very high energy performance (very efficient) [3], the amount of energy required from the Grid is almost zero or very low than needed and can significantly generate energy from renewable energy sources (RES). The definition of NZEB can be found in various literatures [6,7,8,9]. The basic elements in definition of NZEB and their relationship are shown in figure.1. The basic elements are building system, energy grid and weighting system. In order to make a clear balance calculation for the net zero goal, a boundary need to be clarified for the building system with on-site renewable. Inside this boundary, building system consumes delivered energy, such as electricity, natural gas, from on-site renewable and energy grids, and output energy back to the grid when the REP (renewable energy power) system generates excess
