This study examines the design of the ITB Cirebon dormitory building aimed at achieving Net Zero status through the harmonization of passive design and green technologies, in accordance with the ITB Cirebon masterplan and various applicable regulations and design standards. The building design is engineered to be easily constructed using precast methods and meets fire safety criteria (Ministry of Public Works Regulation No. 26 of 2008), disability accessibility (SNI 03-1733-2004), as well as health, comfort, and convenience standards (UU No. 28 of 2002 and PP No. 16 of 2021).Passive design is implemented using the Fanger theory approach, resulting in a Predicted Mean Vote (PMV) of +0.41, which exceeds the BCA Greenmark standard (PMV +0.6). Radiation and wind are controlled through proper building mass orientation and the use of radiation shading fins and cross-ventilation systems. The building achieves Super Low Energy (SLE) and Positive Energy (PE) status according to BCA Greenmark, as well as Triple Net Zero status according to LEED Zero USGBC. Passive design strategies, proper orientation, and building shading fins reduce operational energy use by 65.4%, meeting the SLE BCA Greenmark requirements. Energy from solar panels generates 285,125 – 368,985 kWh per year, sufficient to meet the operational needs of 265,156 kWh per year, achieving Net-Zero Energy (NZE) and Positive Energy (PE). The carbon emissions from the design, initially at 175,564 MJ, are reduced to 85,325 MJ through the substitution of reinforced concrete columns and beams with Glued Laminated Timber (GLT), and floor plates with Cross-Laminated Timber (CLT), resulting in a 54% reduction in structural carbon emissions. Over a 50-year period, carbon emissions totaling 49,007,247 MJ are offset by clean energy, avoiding emissions of 51,322,442 – 66,417,278 MJ, achieving Net-Zero Carbon (NZC) status. A rainwater storage volume of 1,510 m³ sourced from rainwater meets the water needs throughout the year, achieving Net-Zero Water (NZW) status. Waste management reduces potential waste by 94.5% through recycling, Black Soldier Fly (BSF) utilization, and composting, providing opportunities for Net Zero Waste. The urgency of climate change and the Paris Agreement make the implementation of Net Zero concepts on campus a crucial first step towards larger-scale sustainability. The investment in this building provides a financial return of 1,176% with affordable rental costs and low operational expenses, as well as social benefits through education, scientific research, and environmental awareness enhancement.
