Implementation of Green Building at Bandung City are regulated by Bandung Mayor Regulation No. 1023 of 2016 about Green Building. The new building that still on the design phase are required to follows the regulation and must be assessed by the regulation, so that the simulation must be performed to predict the building performance. However, the said regulation still lacking of energy and daylight performance criteria at the moment and it can lead to obstruction at the assessment phase. Proposed criteria for the said regulation using the metric of Energy Usage Intensity (EUI), SDA300/50%, and ASE1000,250. These metrics already used as performance indicator in Green Building standard reference in this research, that are GREENSHIP, Jakarta Governor Regulation No. 38 of 2012 about Green Building, and LEED v4. The purpose of this research is to generate EUI, sDA300/50%, and ASE1000,250 value so it can be used as reference for new energy and daylight performance criteria in Bandung Mayor Regulation No. 1023 of 2016. To achieve a purpose of this research, modeling and simulation of building are performed using the Autodesk Revit and Autodesk Insight respectively. Building model of educational and office are created, then its passive design, that are building orientation, Windows-Wall Ratio (WWR), glass material, and wall material, are varied until it has ninety design combination for each building. The interval value of average with 95% confidence level shows EUI and SDA300/50% can fulfill the criteria of standard reference, but not with ASE1000,250. Sensitivity analysis performed in this research to determine most significant passive design parameter that impact the energy and daylight performance. WWR is the most significant passive design parameter that impact the energy and daylight performance of building. The results of sensitivity analysis are used to propose new criteria building design. The proposed energy dan daylight performance criteria in this research are based on value at 1st quartile, 2nd quartile, 3rd quartile, and criteria at standard reference. Proposed energy and daylight performance criteria for Bandung Mayor Regulation No. 1023 of 2016 based on simulation results of this research are: • For educational building, One Star if EUI 230-259 kWh/m2/year, Two Star if EUI 209-230 kWh/m2/year, and Three Star if EUI < 209 kWh/m2/year and for office building, One Star if EUI 169-181 kWh/m2/year, Two Star if EUI < 163-169 kWh/m2/year, dan Three Star if EUI < 163 kWh/m2/year. • One Star if SDA300/50% > 30%, Two Star if SDA300/50% > 49%, dan Three Star if SDA300/50% > 75% with threshold ASE1000,250 < 10 %. The additional requirement about building envelope optimization also added for the building with longest wall facing East-West side and WWR > 30%.
