Arup Associates with Mace Sustainable Project CN Awards 2016
Arup Associates with Mace – Believe in Better Building
Arup and Mace’s Believe in Better Building used timber for its speed and sustainability. The lightweight timber superstructure reduced foundation loads by 13 per cent, with the substructure concrete using 40 per cent PFA cement replacement and 100 per cent stent secondary aggregate to cut its embodied carbon by 37 per cent.
The building uses passive design and efficient systems to achieve 40 per cent less emissions than Part L 2010. In total, the combined renewables and embodied carbon efficiencies in the timber are expected to produce a carbon saving of 67 per cent over the building’s life.
Bam Nuttall Sustainable Project CN Awards 2016
Bam Nuttall – Wallasea Wild Coast project phase one
The Wallasea Wild Coast Project is a landmark conservation and energy scheme on a scale never attempted before in the UK. Bam Nuttall, in partnership with ABPmer, Aecom, Capita, Crossrail, the Environment Agency and the RSPB, has created a new wildlife reserve on the South-east coast using three million tonnes of spoil from sources including Crossrail.
Stage one formally opened in September 2015 after three-and-a-half years on site, with water transport of material saving the equivalent of 150,000 lorry journeys, with the new tidal saltmarsh estimated to have the potential to sequester more than 500 tonnes of carbon per year.
CNIM Clugston Leeds RERF Sustainable Project CN Awards 2016
CNIM Clugston (Leeds) – Leeds Recycling and Energy Recovery Facility
Constructed by CNIM Clugston for Veolia Environmental Services, the Leeds RERF will divert more than 200,000 tonnes of waste from landfill each year, extracting recyclable material from waste before using what remains to generate electricity that is fed back into the National Grid.
The building’s striking feature is its arched glue-laminated FSC-sourced timber frame superstructure – said to be the largest timber-frame building in the UK and the largest of its type in Europe, which stands 42 m high and 123 m in length.
Leeds RERF also has a 1,800 sq m living green wall on its southern elevation fed off a single irrigation system, which the team also believes to be the largest of its kind in Europe.
John Sisk and Son Sustainable Project CN Awards 2016
John Sisk & Son – 7 Air Street
The redevelopment of 7 Air Street in central London saw John Sisk unify and extend two Grade II-listed buildings to provide new office space and a restaurant shell, above occupied retail stores.
The project required heavy structural alterations to create a single core and extended floor plates on two levels, all while ensuring the building achieved a BREEAM Outstanding rating.
It is connected to a central energy centre, which significantly reduces its CO2 emissions and achieved a final BREEAM score of 94.1 per cent, exceeding the 90.65 per cent achieved at design stage.
Lendlease Sustainable Project CN Awards 2016
Lendlease – Cobalt Place
Located in Battersea, London, Cobalt Place is described as the world’s largest cross-laminated timber residential development to be delivered to date, comprising 102 apartments and two townhouses.
It uses a CHP plant, which powers it and an adjacent 1,050-pupil school, St John Bosco College, built as part of the scheme.
Lendlease achieved development CO2 emissions 25 per cent lower than homes built to current Building Regulations standards and household water consumption of 30 per cent less than the average household at approximately 105 litres per day.
Morgan Sindall Sustainable Project CN Awards 2016
Morgan Sindall – The Enterprise Centre, University of East Anglia
Morgan Sindall’s Enterprise Centre at the University of East Anglia used a new low-carbon concrete for its foundations, as well as 25-year-old oak from a local timber yard for external finishes.
A highlight was the team’s use of thatch. Sourced locally from Norfolk and Suffolk, the straw was used to fill offsite-manufactured timber cassettes, which systematically wrap the building.
The building beat Passivhaus air tightness standards (hitting 0.21 air changes per hour), diverted 99.41 per cent of waste from landfill, and will generate 43.58 MWH annually through its solar panels, and harvests rainwater from its roof.
South Tyneside Council Sustainable Project CN Awards 2016
South Tyneside Council, Northumbrian Water, MWH and Esh Construction – Fellgate surface water management
Fellgate estate in Jarrow, North-east England, has had a history of flooding and suffered extensive damage in 2012 following heavy rainfall, affecting 175 properties.
The project team came together to devise a sustainable approach to surface water management, identifying where sustainable urban drainage systems could be used over conventional drainage.
MWH combined SUDS with conventional sewer network enhancements to manage water, including swales, bunds and detention basins that blend in with the environment, with construction carried out by Esh.
Willmott Dixon Sustainable Project CN Awards 2016
Willmott Dixon Interiors – The University of Brighton, Cockcroft Building
This fit-out project saw Willmott Dixon Interiors refurbish an 11-storey, 15,000 sq m 1960s teaching block. The two-and-a-half-year programme took place over four phases, with the team working on two floors at a time while the rest remained operational.
The team’s modernisations will reduce the building’s energy demand by 57 per cent, saving the client approximately £82,000 per year, while the 230 sq m of solar PV panels will reduce CO2 emissions by 18 tonnes per annum.
WDI also installed an aquifer thermal energy system, using two holes bored into the chalk landscape below.
WRW Construction Sustainable Project CN Awards 2016
WRW Construction – Burry Port Community Primary School
This project saw Burry Port Infant and Junior Schools merged into one Community Primary School, providing accommodation for 210 pupils alongside a 30-space nursery class and crèche.
WRW remodelled the existing infant’s building and added two new extensions, as well as building a new two-storey junior building.
The school is the first primary school in Wales to achieve the Passivhaus standard, helping to reduce the school’s energy bills by up to 90 per cent.
