Fonseca et al. (2018) achieved nearly zero-energy building goals in the renovation of theuniversity campus building by adopting an integrated approach such as the rightcombination of different strategies, including energy-efficient technologies and renewableenergy. However, further investigations based on software analysis seem to be necessary forenergy efficiency and the construction of efficient buildings with near-zero energyconsumption. Amani and Reza Soroush (2020) investigated the simultaneous effect ofparameters affecting energy consumption in the building. These parameters includedBuilding orientation, window-to-wall ratio (WWR), Window shades, Window glass, Walland Roof construction, Infiltration, Lighting efficiency, Daylighting and occupancy controls,Plug load efficiency, HVAC system, Operating schedule and photovoltaic system. Theirfindings showed that the simultaneous investigation of parameters affecting energyconsumption in the case study building could save energy costs up to 58.23%. Hence, it canbe concluded that each of the building components has a significant role in evaluating theenergy performance of the building, which should be considered in the energy analysis.The use of a photovoltaic (PV) system for zero-energy buildings is crucial to balance energyconsumption. The potential of using PV systems for residential buildings in different climaticzones of China was investigated by Liu et al. (2019), taking into account parameters such as tiltangle, orientation, plot ratio, PV conversion efficiency and location. The results indicate thatsouthwest China is the best place to develop zero energy buildings. Low-rise residential buildingscan realize zero energy in China when the PV conversion efficiency is higher than 20%. Thepotential of using nearly zero-energy buildings (nZEB) was investigated by Al-Saeed et al. (2020)to improve the performance of residential buildings in the hot and dry climate of Iraq. Theirfindings showed that both significant annual energy reductions and nZEB standards have beenachieved, which could range from 41% to 87% for current climatic conditions. Walter Costa et al.(2020) conducted a study on pure energy office buildings in the hot climate of Brasilia. Theirstudies showed that the nZEB goal could be achieved in office buildings up to four floors in theBrazilian climate zone by following the nearly zero-energy building improvement guidelines.These guidelines included measurement of available building shell for collecting solar irradiation,the reduction of the WWR, using glasses with a Solar Heat Gain Coefficient of 43% or lower, theaddition of solar shading devices, the reduction of the installed power density of the lightingsystem by 25% and the use of natural ventilation. The potential impacts of energy-efficientmeasures for retrofitting existing UK hotels to reach the nearly zero-energy building (nZEB)standard were investigated by Salem et al. (2019). The findings show that it is possible to achievethe nZEB standard for older UK hotel buildings. Thus, attention must first be paid to improvingthe building fabric or building envelope elements, then if necessary, to achieve the nZEB goalin the historical buildings can be used the renewable energy systems. Al-Saadi and Shaaban(2019) conducted a study based on the design of sustainable architectural and engineeringsystems for a zero-energy building (ZEB) in the hot climate of Oman. Sustainable passive andactive energy systems have been successfully integrated into this building typology. Passivestrategies have resulted in a small equipment capacity of air conditioning systems. However, aPV system was installed on the rooftop providing electrical energy for immediate house demand.A solar water heater was also installed to provide free hot water. The results showed that whengrid interaction was considered, 40% of the building load was supplied by site generation, whichmeets zero energy targets. Albadry et al. (2017) proposed increasing insulation surfaces to reduceenergy consumption and design a photovoltaic system for renewable energy to reach the nZEBtargets for a 5-story residential building in Egypt. Charisi (2017) stated that the appropriatecombination of the building shell and increasing the insulation layer thickness in achieving thenearly zero-energy building of a residential building in Greece could save up to 30% in energyconsumption.
