Realistic Energy Efficient Tunnel Solutions (REETS)
The Realistic Energy Efficient Tunnel Solutions (REETS) project aimed to enhance the energy efficiency of road tunnel operation, through the assessment, promotion and implementation of appropriate technologies. REETS is being led by TRL with a consortium of partners comprising of AIT, Mouchel and Designs for Lighting.
In terms of both construction and operation, tunnels are the most energy demanding of road infrastructure assets. The construction of a road tunnel is energy intensive due to the volume of excavation required and the energy embodied in the materials that form the structure of the tunnel. In operating a tunnel, energy is consumed to provide adequate lighting, ventilation for drivers and to maintain drainage systems. A significant amount of equipment is also installed to deal with emergency situations. With a tunnel’s operational lifetime typically in excess of 100 years, energy usage through operation can soon outweigh that due to construction and therefore the former provided the focus for this project.
