Under the framework of Building Information Modeling (BIM), services such as Computational Fluid Dynamics and Carbon Monoxide (CFD-CO) analysis, hydraulic calculations, energy modeling, and green building consultancy have become integral components of sustainable design and construction practices. Utilizing BIM technology, experts can simulate fluid dynamics and air quality to optimize ventilation systems and ensure indoor environmental quality. Hydraulic calculations aid in designing efficient plumbing systems, while energy modeling allows for the evaluation of energy consumption and the implementation of renewable energy strategies. Green building consultancy services under BIM offer comprehensive sustainability assessments and recommendations, guiding projects towards achieving green building certifications and minimizing environmental impact, all while maximizing energy efficiency and occupant comfort.
