The study was conducted to create a link between the outdoor environment and occupant without compromising the occupant comfort. The aim to create the net-zero energy building, using passive strategies, and promoting comfort. The means of passive design studies such as climatic analysis, daylight studies, and thermal comfort studies for natural ventilation. The second stage of design consists of optimization of modeling business as usual case, the elimination parametric simulation followed by sensitivity analysis, and HVAC optimization. There was a reduction of 40% after the envelope optimization and a further 22% reduction after HVAC optimization. The design case is compared with BAU and ECBC Case. The Third Stage consists of energy generation. The total energy generated was 75,000 kWh. For the net-zero energy building to be designed the EUI should be less than 55 kWh/ sqm. The design case-building EUI is 44.78 kWh/sqm. Thus, the building is net positive in energy with ROI of 28% and payback 3.1.
