Energy performance sensitivity analysis on building's passive technologies effective parameters, in an NZEB EnergyPlus-simulated villa in Tehran's weather conditions with OFAT methods

As it is clear, today's important subject is energy and ways to decrease its consumption. This subject gets more critical in countries with difficulty providing energy for their building consumption, which is responsible for about 30% of annual energy consumption in the whole country. Iran, because of its geographical location, confronts these problems. Passive technologies are essential in NZEB buildings to reduce annual energy consumption. In this research effects of using three significant passive technologies: Roof Vegetation, smart blinders, and Thermochromic windows, are studied separately in EnergyPlus software. The result of this research is that using smart blinders and Thermochromic windows at their optimum condition can reduce the annual energy consumption of a building in the climatic circumstances of Tehran by about 56.51% and 37.94%, respectively.
