Digital Twins Can Reduce Construction Carbon Emissions by Integrating Life Cycle Sustainability

Why It Matters

The construction sector is a major contributor to global carbon emissions. By leveraging digital twins, designers and engineers can gain unprecedented insights into the environmental impact of their decisions from conception through demolition, enabling proactive mitigation of greenhouse gas emissions.

Key Finding

While digital twins are increasingly used in construction, their potential for reducing carbon emissions and improving overall sustainability across a building's entire life cycle is largely underexplored and requires a dedicated strategic approach.

Key Findings

• Existing digital twin applications in construction primarily focus on productivity, safety, and management, with limited emphasis on sustainability and carbon emission reduction.
• Digital twins have the potential to enhance sustainability across all phases of a building's life cycle: design, construction, operation, maintenance, renovation, and demolition.
• A conceptual framework is proposed to guide the integrated implementation of digital twins for sustainability in the construction sector.

Student Guide (IB Design Technology)

Simple Explanation: Digital twins are like a virtual copy of a building that can help us see how it affects the environment throughout its whole life, from building it to tearing it down, so we can make it more eco-friendly and reduce pollution.

Why This Matters: Understanding how digital twins can be used for sustainability is important because the construction industry has a huge impact on the environment, and new technologies like digital twins offer solutions to make it greener.

Critical Thinking: To what extent can the current limitations in data availability and interoperability hinder the effective application of digital twins for comprehensive sustainability assessment in construction?

IA-Ready Paragraph: This research highlights the significant potential of digital twin technology to address the pressing challenge of carbon emissions within the construction industry. By extending the application of digital twins beyond mere productivity gains to encompass the entire building lifecycle – from initial design through to demolition – a more holistic approach to sustainability can be achieved, enabling proactive identification and mitigation of environmental impacts.
