Ali Idrisabadi, an expert on this research, said: “Today, the notion of zero-energy building has been recognized and expanded in the scientific community. The European Union has set long-term goals for 2050, and the construction sector needs to be rebuilt to reduce its GHG emissions from 1990 to 2050 by 80 to 95 percent.
He stated that so the desire to design and technology solutions to increase the energy output to zero has been increased, he said: The project explores several manufacturing technologies or energy production systems that also build energy storage buildings Which tries to achieve zero energy.
According to him, for this purpose, the building was originally designed in terms of architecture. At this stage, after reviewing the available options, the use of the LSF prefabricated wall was chosen as the building material as the optimum material.
Edrisabadi noted that the amount of solar energy in Tehran’s geographic region (Mehrabad) was determined; the energy needed to meet the interior needs of the building (lighting, heating and cooling), photovoltaic system in the network-connected situation for this design building The simulation showed that the amount of energy produced by the photovoltaic system was 2252 kilowatt-hours per year and the energy consumption of the building was 2019 kilowatt-hours per year.
He also said that by designing 12 photovoltaic modules on the roof of the zero energy building with a total effective surface of 05.18 square meters, the total radiation of 7.20621 kWh from the sun on the cell surface and, eventually, 1.2469 kWh Power was generated on the home network.
“The solar heating system was simulated with T * SOL software, from the design of the heating systems,” said the researcher, saying that the calculations in the simulation showed that using the photovoltaic system prevented the release of 1310kg CO2 per year. The double-glazed tank system with the highest efficiency of 5.15% was chosen as the optimal solar heating system.
He continued: The solar heating system consists of a vacuum tube collector with a double-glazed tank with 160 liters of water consumed daily at 50 ° C and 750 liters tank capacity. Replacing the system will prevent annual emissions of 1676 kg of CO2.
