Problem Addressed

Determining the environmental impact of a construction project can be difficult especially with numerous sectors and supply chains to calculate and report. Choosing where opportunities for decarbonisation exist requires not only a detailed understanding of the project but also guidance for making the right decisions. eTool addresses the challenge of environmental sustainability in construction by providing detailed insights into the carbon footprint and other environmental impacts of projects. By identifying areas with the highest environmental impact, it assists in making informed decisions to improve sustainability.

Solution Overview

The flagship software by Cerclos, eTool, is a collaborative solution for organisations to effectively measure, improve, and report on the whole-life carbon emissions of their building and infrastructure projects. The tool helps architects, engineers, and project managers aiming to minimise carbon emissions and adhere to sustainability standards. It allows users to analyse various aspects of a project’s design and operation, identify the most significant sources of emissions, and explore alternative, more sustainable options. This helps in making informed decisions to reduce the overall environmental impact.

While eTool can function as a standalone solution for life cycle assessment, it can be used in connection with other solutions such as AutoCAD and BiM models, but its effectiveness as a standalone solution provides a more comprehensive approach to sustainable construction. Compared to spreadsheet-based approaches, eTool is more accurate and reliable while also allowing users to quickly compare various scenarios through its Scenario Optioneering to find the best improvement strategies at the lowest cost.

eTool also has a growing library of thousands of templates for construction components, energy & water use, benchmarks, and more. LCA studies can be third-party verified via eTool’s certification system to ensure a project complies with a variety of international rating schemes and standards. Cerclos is also committed to ensuring eTool’s full alignment with the latest RICS Version 2.0.

The effectiveness of eTool can be measured by comparing the projected environmental impacts of a construction project before and after implementing changes based on eTool insights. This could include quantifiable metrics like percentage reductions in carbon emissions, energy use, or resource depletion. Additionally, achieving higher ratings in green building certifications due to improvements guided by eTool can also serve as a testament to its effectiveness.

The expected returns for using eTool can be substantial when considering long-term savings, enhanced project value, and alignment with sustainability goals. The actual cost-benefit ratio will vary depending on the specific use case and scale of projects.

Case Study

eTool facilitated HS2’s Carbon Management Plan, supporting the project’s goal of minimsing carbon emissions around design, construction, and operational phases. Through its life cycle assessment approach, eTool aided in setting baselines for design options, enabling HS2 and its subcontractors to identify opportunities for improving life cycle performance. This approach was integral to setting ambitious carbon reduction targets for the project’s supply chain.

The software’s effectiveness was further validated through a PAS2080 audit by Lloyd’s Register Quality Assurance (LRQA) on HS2’s greenhouse gas reporting processes, demonstrating eTool’s transparency and reliability.

Key benefits realised by HS2 using eTool include:

  • Consistency in data input and reporting
  • Efficiency in quantification and automated reporting processes
  • Transparency for efficient assurance and deliverable acceptance
  • Utility of Data to inform future project stages and asset management
  • Integrated Design on a single platform for whole project life cycle carbon management
  • Compliance with regulatory standards like PAS2080 & BREEAM Infrastructure
  • Agile Development for customised feature enhancement

This case study underscores eTool’s ability to support major infrastructure projects in achieving sustainability and carbon reduction objectives, establishing it as a valuable tool in environmental impact assessment and collaborative project management.
