implementation of a zero-energy building scheme for a hot and dry climate region in iran (a case study, yazd)

In this research work, a plan to implement a zero-energy building (zeb) scheme for a hot and dry climate region in iran, i.e. yazd, is introduced and a comparison with a typical house of that climate is performed. based on the climate conditions, several active or passive methods are available in order to create a balance between the energy supply and the demand, namely improving wall insulations, by using efficient heating/cooling devices, using solar energy, utilizing energy storage devices, etc. here, the sketchup software is employed to present the plot of the selected building. in addition, one of the interfaces of the energy plus software called beopt is used for performing the energy and economic analyses on the fast-constructed and pre-fabricated schemes. considering the equipment’s world price, the results obtained demonstrate that the zeb scheme in selected climate conditions is applicable, and the payback period is estimated to be about 5.5 years. in addition, replacing the typical buildings with a zeb will decrease carbon dioxide emissions by about 27.4 metric tons/yr.
