Canal locks, offices, universities and motorways are among the exceptional projects shortlisted for their environmental achievements.
Amco Engineering – Iden Lock improvements
Iden Lock lies at the junction of the River Rother and the Royal Military Canal near Rye in East Sussex.
Dating back to 1808, the lock and canal are Scheduled Ancient Monuments, constructed as a line of defence during the Napoleonic War, and the lock is also Grade II-listed.
The improvement project saw Amco Engineering replace the existing tilting weir, lifting mechanism and pumping system to improve energy efficiency, provide better control of canal water levels and reduce health and safety risks around operation and maintenance.
Originally one of the five most carbon-hungry Environment Agency sites in the South-east, Iden Lock is no longer in the top 10 and has had a huge positive impact on the local community.
Eric Wright Construction / Muse Developments – Number One Bickerstaffe Square
Number One Bickerstaffe Square is the central element of Muse Development’s Talbot Gateway Central Business District in Blackpool.
The project has been designed to offer sustainable socio-economic benefits for Blackpool by becoming the centrepiece of a high-calibre commercial district that will attract inward investment and generate jobs.
As well as economic sustainability, the office building has achieved a BREEAM Excellent and an EPC A rating and includes PV panels, rainwater harvesting and LED lighting.
Kier Construction – Five Pancras Square, King’s Cross
Five Pancras Square is a new community hub for Camden Council that reduces the council’s carbon footprint by an estimated 64 per cent compared with the buildings being disposed of, consolidating council premises into a single, more efficient site.
This sustainable building will save the council £500,000 a year in energy costs alone and in 2008 achieved a BREEAM Outstanding score of 93.05 per cent, the highest that year.
A post-construction rating of 97.12 per cent is anticipated, making it the first Outstanding council headquarters with a swimming pool.
Sir Robert McAlpine – Birley Building, Birley Campus, Manchester Metropolitan University
Mirroring its wider environmental objectives of achieving zero energy, zero water and zero waste, as well as maximising biodiversity, Manchester Metropolitan University’s vision for the Birley Building was for sustainability to be integrated into every aspect of its design.
The building has a CHP energy centre to meet its heating and hot water requirements (and those of the rest of Birley Campus), ground-source heat pump boreholes to provide a free cooling source, rainwater recycling, LED lighting, a sensory garden and numerous other sustainability features.
Skanska Balfour Beatty joint venture – M25 LUS, Managed Motorway All Lanes Running (Section 5)
As the first Managed Motorway All Lanes Running project to be completed in the UK, the Skanska-Balfour Beatty JV was able to reassess how a motorway could be constructed, encompassing the three pillars of sustainability alongside an exemplary safety record.
By viewing the existing asset as a usable resource, the design saw 100 per cent of all excavated hard fill processed into aggregates and recycled back into the scheme, accounting for an unprecedented 94 per cent of all unbound aggregates used.
In addition, 99.9 per cent of waste was diverted from landfill and the project’s carbon footprint was 60 per cent lower than traditional widening schemes.
Skanska UK – Bentley Works redevelopment
The redevelopment of the home of Cementation Skanska for over 100 years is the first Skanska development project to achieve zero carbon, BREEAM Outstanding and meet Skanska’s criteria for Deep Green in the UK.
BIM lead design and offsite fabrication reduced site waste to 1.8 tonnes per 100 sq m and 100 per cent of waste was diverted from landfill, while the office will be carbon-positive in operation at 102 per cent better than Building Regulations.
The project was finished to time and budget and secures Skanska’s long-term future in Doncaster.
Speller Metcalfe – Western Power Distribution, Spilsby
Western Power Distribution’s 650 sq m depot in Lincolnshire achieved a 101.9 per cent BREEAM Outstanding rating, the highest-rated BREEAM project in the world as of August 2014.
Renewable technologies account for 95 per cent of the building’s energy use, with experience of previous BREEAM Excellent schemes enabling Speller Metcalfe to create an accurate, high-quality Level 2 BIM model.
Sustainability was integrated into the project lifecycle, from the choice of location to design stage, construction and post-occupancy for the client.
