The Leeds RERF (Recycling and Energy Recovery facility) is the flagship development at the heart of Leeds Integrated Waste Strategy over the next 25 years. The facility will process over 200,000 tonnes of household waste per annum, generating 13MW of electricity to power up to 22,000 homes a year. The scheme harbours further ambitions by providing on-site pre-treatment technology which will sort up to 20% of all waste brought to site ready for recycling – waste which would otherwise have been sent to landfill. 

TSP Projects were Lead Designers on the detailed design, coordination and delivery of this ambitious project delivering Architecture, Civil and Structural Engineering, Highway & Drainage, M&E, Environmental consultancy, Landscape Architecture, Geo-Technical and Fire Engineering design alongside overall responsibility for design co-ordination with the French process Engineers CNIM as well as numerous sub-contractor design packages as part of our co-ordinated approach to multi-disciplinary delivery.

TSP Projects also played an instrumental role in supporting the two formal environmental assessments undertaken on the building and associated infrastructure. TSP Projects not only produced sustainable designs to support the BREEAM Bespoke and CEEQUAL infrastructure assessments, we also provided the qualified and licensed assessors to independently audit and verify the evidence on behalf of BRE.

TSP Projects specified sustainable materials for use in the building fabric and insulation, achieving high ratings under the BRE’s Green Guide to Specification. The design also included sustainable drainage techniques such as permeable paving, rainwater harvesting to minimise demand on potable water and attenuation ponds and swales which reduced peak flow rates for surface water run-off by 43.8% post-development.

The project achieved a BREEAM Excellent rating at final certification with a score of 73.5% and a CEEQUAL Excellent Rating (Whole Team Award) with a final score of 80.5%. The building itself has an iconic glulam timber frame structure – the largest timber frame building in the UK and the largest of its type in Europe. At 42m high and 123m in length the main timber arches create an uninterrupted 34m span over the complex process machinery within. Integration of the specialist timber frame superstructure has meant the use of the latest BIM software has played a significant role in the design process.

Amidst the timber frame, on the buildings southern elevation is a green ‘living’ wall creating a visually stunning feature in stark contrast to the buildings industrial use. The wall is set to enter the Guinness Book of Records as the world’s largest living wall fed off a single irrigation system. The feature will soften the buildings visual impact and provides vital biodiversity benefits to the site and surrounding industrial area.
