Green Plus Project Objectives
  • Develop and implement an energy management methodology that can be applied to all significant projects to help reduce the organisation’s GHG emissions, improve its energy performance while raising energy conservation awareness across its workforce.
Key Challenges
  • Projects that Roadbridge undertake can vary greatly in size, complexity, timescale and location (e.g. remote areas with limited communication coverage). The specific requirements of Roadbridge Clients and other key stakeholders can also impact the implementation of the methodology.
Key Changes
  • The scope of this project was broadened to encompass the entire company, which impacted the energy review and the established energy baselines.
  • Knowledge transferred and skills developed to allow Roadbridge to apply the Energy Management Methodology to all significant projects. Methodology applied adheres to international best practice and is subject to assessment by third parties.
    • Over the course of this programme, Roadbridge have introduced six fully electric vehicles into their fleet, removing an equivalent number of diesel cars from the roads;
    • Electric vehicle charging points are now being incorporated into the site mobilisation set up of new projects, and five have been installed to date;
    • Roadbridge have recently purchased two Hybrid Excavators to begin the process of moving from a reliance on fossil fuels;
    • A retrofit of all lighting at Head Office took place, with a payback period of two years.
