BIM for Sustainable Construction

 Sustainable construction aims to take the most energy-efficient and environment-friendly route for your construction project needs. It involves devising vernacular strategies and deploying renewable methods to develop a building project to leave the least amount of impact on the environment. 

The most misplaced notion about sustainability is that the goal is to get one final output or to use certain design aspects. However, sustainability is more of a process. A process that has to be thought of at every interval of the project. The more a project is being intervened with a sustainable approach, the better it gets in terms of all kinds of values associated with it.   

 With the arrival of BIM (Building Information Modeling), 3D models are now more information-rich. Apart from more physical data, BIM models can be embedded with non-physical aspects also that could give leverage to your design approach. The other important aspect of BIM in comparison with linear 3D modeling is the real-time shareability across the stakeholders. BIM projects deployed on the cloud could be editable among all the stakeholders. This information richness and shareability factors associated with BIM make it a better prospect than regular CAD modeling in terms of sustainable development.  

This is exactly where a BIM approach, especially 7D BIM, can help you in elevating your design outputs on sustainable parameters. Here are some of the ways in which Building Information Modeling (BIM) felicitates sustainable building design:  

Utilizing BIM Tools for Energy Efficiency  

The examination of environmental elements during the design phase is made possible by BIM's 7D modeling capabilities. Designers might be prompted to create a design using certain BIM systems depending on variables analysis on energy usage. Further, the analysis of energy usage can be segregated into probes on metrics like the thermal efficiency of the output or the lighting requirements of the facility. This is intended for evaluating a project's energy usage, carbon footprint, and, therefore, overall environmental effect.   

Virtual Environment – Tool for Energy Simulation And Monitoring   

The Virtual Environment (VE) is a BIM software for energy simulation, providing integrated analytical tools for building design and retrofit, enabling cross-team cooperation, and integrating energy and performance studies throughout the design process. Acting as a digital twin cloud command center, it helps you to dive deep into various sustainability metrics. The wide variety of products it offers are:

• iSCAN: Any time-series data from various building and energy management systems, utility portals, IoT sensors, and historical files may be centralized in one platform using iSCAN.   

• iCD: Implement sustainable master planning from the beginning, integrating analysis across sustainable criteria and utilizing the iCD SketchUp plug-in for accurate energy analysis.  

• iVN: With the integration of power, heat, cooling, water networks, electric vehicle charging, renewable production, and district heating, the iVN suite evaluates local energy decarbonization possibilities for growth.  

Achieving Operational Efficiency and Reducing Environmental Impact  

BIM's ability to provide transparent and comprehensive information allows project stakeholders to plan construction and future operations more effectively, avoiding project overruns and delays. This reduction in errors and waste minimizes the project's environmental impact and promotes sustainable practices. Sustainability is not just the allocation of renewable resources at your disposal but also a smart design approach to avoiding overwork.   

This could be easily channelized through software specifically developed for   

• 4D BIM scheduling & simulation 
• 5D (Cost estimation)  

• 6D (Facility management)  
• 7D (Sustainability)  
• Now even 8D use cases of BIM technology that focuses on health and safety.

Prefabrication With BIM  

BIM provides a more thoughtful route to prefabrication operations. Prefabrication entails creating construction components off-site and putting them together afterward, improving the efficiency of activities on-site. Just coupling this BIM generates a more collaborative and documented prefabrication approach. This ultimately results in a decrease in on-site waste, labor needs, and consequent environmental consequences even more.   

Vertex – BIM for Prefab and Modular Design  

Vertex BD is a BIM software for prefab and modular projects, utilizing digital automation to automatically generate and save various project data across disciplines. Asset management does play a big-time role in imposing sustainability metrics on pre-fabrication methodologies. It is about the lifecycle of each individual product constituting a space. With asset management, we could analyze individual elements based on their embodied energy.

Spacewell – BIM for Smart Asset Management   

The Spacewell BIM software for facility management repurposes your BIM model for digital twin monitoring. Then, in follow up to that, it helps you track assets and manage inventory levels for facility maintenance.   

BIM Data for Sustainable Post-Construction Processes  

BIM models and drawings created during the design and construction phases contain valuable data that can be leveraged for building operation and maintenance. By using BIM as a reference for post-construction processes, sustainable building design extends beyond the initial stages to ensure long-term efficiency and maintenance. Further, this can be doubled on the integration of BIM and IoT altogether. We always refer building industry to be causing 40% of global carbon emission, but the major portion is how these buildings function.

 These could be totally improved through smart monitoring of properties by integrating the best of BIM, IoT, and digital twin practices on one interface.   

UsBIM – Integrated IoT-BIM Tool 

usBIM.IoT can be used for integrating the BIM modeling interface with constant real-time IoT data. Using usBIM.IoT, you can easily integrate IoT device monitoring and remote control into your BIM model, creating a dynamic system that responds to IoT device outputs and events in real time, bettering your design decision. In the write-up above, BIM software has been discussed with respect to their specification. However, to achieve a greater goal of sustainable development, one should opt for one holistic software suite. On this line, SelfCAD software suite could be the solution for your sustainable design expectations. This 3D modeling software consists of all the artistic and technical tools for designing your designs from scratch.

You can also import your 2D drawings, trace around using freehand drawing and sketching tools and thereafter convert those profiles to 3D models. If you would like to 3D print your designs after designing, you can use the in-built online slicer of SelfCAD to do so. The slicer is easy to use and it’s compatible with most of the common FDM 3D printers.

The Future of BIM as a Smart, Sustainable Approach   

The BIM software segment specifically allotted to sustainability would definitely expand with more and more solutions from tech companies. Although traditional options like Revit and Navisworks are surely exploring integration options, there will still be new solutions tuned to stringent green certifications. Also, from the recent development in AI, the future of the BIM market would be to narrow down the solutions to achieve more sustainable parameters precisely at the backend of your design operations.
