How does BIM help in building ?Green Buildings?Posted by Brian Smith on December 26th, 2017 The concept of creating sustainable designs and building & operating structures that are more eco-friendly are gaining ground as the impact of construction on the environment has seen adverse ecological impact. Although green buildings remain an admirable goal, there are a lot of challenges that need to be addressed. Achieving a balance between long term gains and short term costs impact the choice of building techniques and strategies selected. The concept of BIM (Building Information Modelling) is the “big-bang” for creating a green building. BIM modelling is the process of digitally creating a 3D representation of a building which is layered with additional project information. Architects and designers prefer using BIM modelling as it helps them save time and labor during the design phase while giving them more room for simulation and studying the cause effect relationship. It even benefits the contractors as it helps them minimize material cost, labor cost and cost of rework. Designing and operating sustainable green buildings require meticulous resource planning so as to ensure maximum efficiency with minimum impact on the environment. BIM modelling allows architects and engineers to digitally model the different elements of the building such as the shape, structure, heating-cooling, cost, material, time, etc. in real time. The simulation and analysis helps us understand the impact of changes in design on other variables like loads, structure, energy efficiency and the cost. BIM allows architects and engineers to access tools to integrate and analyze parameters like heat gain, ventilation, solar and energy efficiencies in the design. The key elements in designing a green building are the solar strategies, water strategies, and air flow & ventilation as these has maximum impact on the environment. BIM helps in developing these strategies so as to minimize its ecological effect. 1. Solar Strategies 2. Building structure, material, performance strategies 3. Energy Efficiency Streamlined exchange of building information and analytical data has been possible by integrating BIM as a key tool in the design process. BIM provides unparalleled measure of design precision that is beneficial the environment as well as the building industry. The role of BIM modeling in green buildings stands to transform the entire building industry that is poised for change. Like it? Share it! |
