An approach of a Nearly Zero-Energy Building (nZEB) to build an official zone with Micro-grid

Nowadays, “nearly Zero-Energy” Building (nZEB) is one of the most important facts in the whole of Europe. At first in this research, a design had selected for one office building using DesignBuilder software. This office building design will same for 20 other buildings for an official zone. The official zone site had selected in Sevilla, Andalusia, Spain. Afterward, a design had chosen for micro-grid which will be built in this official zone for not only fulfill the nZEB requirement by the European Union but also reduce the energy demand through the main grid. Moreover, design a Solar PV power plant on the rooftop of every office building to fulfill the required energy demand. Moreover, feasibility analysis (for Solar Irradiance) had done for 12 months of 2019 for Ronda Urbana, Norte, Sevilla Andalusia, Spain. Finally, one simulation had run without on-site power generation through renewable energy and another simulation had completed with on-site power generation. In on-site power generation had used large-size wind turbines to power generation through DesignBuilder simulation software which will fulfill almost 4 office buildings of the official zone. This work aims to create an nZEB official zone by using Solar PV generation and Wind Turbine generation system with microgrid by which the generation of Renewable Energy will be improved and make an economic impact for the development of a country.
