What are the best strategies for reducing embodied carbon in construction modeling?

The embodied carbon of a project can be considerably decreased by selecting low-carbon materials, such as salvaged or recycled materials. The integration of life cycle assessments (LCAs) into building modeling facilitates informed material selection, hence mitigating environmental impact.

Selecting low carbon materials in construction modeling is effective for reducing embodied carbon because these materials have a smaller environmental impact during extraction, production, and transportation. By prioritizing materials with lower carbon footprints, you contribute to a more sustainable construction process, ultimately helping mitigate climate change and promote eco-friendly practices in the built environment.

Sourcing the materials from the local manufacturer is the best way to reduce carbon footprint. Buildings must be designed based on the context and nearest available materials. There is no point in procuring recycled material from a different country if you are investing in a much larger quantity of fossil fuel.

Making the switch to materials with lower embodied carbon is an important strategy. Consider alternatives like recycled steel, low-carbon concrete, and repurposed wood. By using these choices, we can significantly lower the total emissions associated with construction projects.

In Malaysia, the my Hijau Mark programme aims to assist project stakeholders in making well-informed decisions regarding building items and materials that are more environmentally-friendly. This is intended to promote the low carbon and green buildings movement.

Optimizing structural design with low carbon materials involves selecting eco-friendly options based on life cycle assessments. Emphasize material efficiency, employ advanced analysis tools, and integrate innovative technologies for sustainable construction. Prioritize recyclable materials, source locally to reduce transportation emissions, and foster collaboration among stakeholders for a holistic approach. This ensures structurally efficient buildings with significantly reduced embodied carbon in the construction process.

Implementing circular economy in construction involves designing for disassembly, reusing materials, establishing recycling systems, adopting modular construction, leveraging digital technologies, and exploring product-as-a-service models. These strategies promote sustainability by minimizing waste, extending material life cycles, and fostering a responsible approach to building design and construction.

I agree. Based on my observation, Malaysia has made significant progress in implementing green procurement under the RMK12. The objective is to ensure that the project development process incorporates and adheres to the notion of sustainability throughout its entire life cycle, including each phase of the life cycle. This include the design of the building, the selection and utilisation of materials, as well as the methods employed in carrying out construction tasks.

To reduce embodied carbon in construction, implement circular economy principles. Design buildings for easy adaptation, reuse, or recycling, minimizing new material use. Concepts like modular design or prefabrication enable assembly with minimal impact. Use recyclable or biodegradable materials. One thing I've found helpful is integrating deconstruction plans into initial designs. Actually, I disagree with prioritizing solely on-site construction, as off-site methods can reduce waste. An example I've seen is a project using modular components that were easily disassembled and reused in future constructions.

Adopting a collaborative approach is the most efficient strategy to reduce embodied carbon in construction projects. The construction project is highly intricate, encompassing multiple phases, activities, and involving various parties with diverse backgrounds and abilities. The challenge is fostering collaboration and transforming into a learning company.

Once the low carbon concrete is dried it looks like any other, yet its existence in the structure adds to the asset value for all stakeholders that will, for the life of the asset, need to track the carbon footprint of their business operations. As-built measurement and verification of embodied carbon within construction, within a true full-lifecycle common data environment will be essential to satisfy the many stakeholders that will engage, and financially and environmentally value, the asset for it's full life..

Encourage cooperation between contractors, engineers, architects, and other relevant parties to make sure that embodied carbon reduction is a team effort. We can all work together to create change and push the limits of sustainable construction modeling by exchanging best practices and expertise.

To cut embodied carbon in construction, monitor and enhance building performance throughout its life cycle. Collect and analyze data on actual carbon emissions versus modeled estimates. Use sensors, meters, or dashboards to track and report carbon performance, pinpointing improvement areas. Employ feedback loops and benchmarks for continual learning and application to future projects. One helpful approach is incorporating real-time monitoring systems from project inception. Actually, I disagree with relying solely on modeled estimates; real-time data provides more accurate insights. An example I've seen is a project using IoT sensors to track energy consumption, leading to targeted efficiency improvements.

The design principles from sustainability based practice like Eco-Design bring a focus on finding the most practically efficient solutions to our common engineering principles. Even a simple review of a finished design to see if something can be done more efficiently or sustainably without sacrificing the design intent can make an enormous difference over the buildings lifetime.

Making sustainability as the core of the design is of paramount importance. Materiality assessment,financial modelling and disruptive business models become the fulcrum to ensure we are focussed on achieving sustainable buildings.

Quantification of materials in the existing site and the amount of work needed on the site needs to be considered. The ability to reuse the materials and reduction in site work can help in bringing down the embodied carbon.
