Considering the vital role of mechanical installations in ensuring the comfort and health of building occupants, this unit relies on the latest standards and handbooks to provide consultation and design of the most suitable installation systems. These designs are tailored to the local climate conditions and comply with national building regulations, with the goal of optimizing equipment and material costs during project execution as well as energy consumption. In this regard, before the physical construction begins, a 3D simulation of the building is carried out in Revit, taking into account architectural, structural, and mechanical considerations. Additionally, using analytical software such as Design Builder, energy consumption and environmental impacts of the building are modeled
