Objective: 

To convert an energy intensive system of heating, cooling and ventilation, which was poorly maintained and controlled into a modern, green, sustainable development while adhering to stringent rail standards.

Actions: 

Network rail worked with a number of designers and regulatory bodies to create a station that would achieve a BREEAM rating of ‘Very Good’. The completed station includes, low energy LED lighting, efficient water spray taps to conserve water, combined heat and power, natural ventilation where possible and rainwater harvesting which provides 60% of toilet flushing demand.  Alternative materials such as carpet tiles with yarn made from recycled fishing nets were incorporated and waste was designed out and reused where possible.

Network rail also worked with ecologists, which led to the creation of a 325m² green wall using 25 different plant species along the Moor Street link to the station and a green roof on and the adjacent accommodation building.

The project also created its own project procurement policy to ensure legal and responsible sourcing of materials. The trains were used to carry material to the site to reduce the need for carbon intensive lorries.

NbS benefits 
  • Reduce load to sewer system
  • Reduce run-off
  • More energy efficient buildings
  • Reduction of energy in the production of new buildings and building materials
  • Increase Biodiversity
  • Changing image of the urban environment
  • Improve air quality

Transferability of the result: 

Can be used for other train stations in need of regeneration.

Lessons learned: 

The project was successful because sustainability was thought about before the designs were drawn up.

It is important to keep all stakeholders involved from start to finish and keep continuous communication throughout.

Financing: 

Funding came from the local council and Advantage West Midlands.
