Temple is delighted to again be sponsoring the Sustainability category for this year’s Constructing Excellence in the South East (SECBE) Awards. These prestigious awards honour exemplary construction projects, recognising excellence by companies and teams that have strived to deliver higher levels of all-round performance.

The 17 award categories cover everything from collaborative working to innovation to SME of the year. Further information on this year’s finalists is available here.

The shortlist of projects and organisations for the Sustainability category for the 2018 awards is as follows:

  • 25 Wilton, London – Kier Construction
  • London Bridge Station Redevelopment Project – Network Rail
  • Oxford Westgate – Laing O’Rourke
  • Principal Place, London Residential Team – Multiplex Construction Europe
  • Heathrow Q6 Delivery Programme – Mace Group
  • Wilmcote House, Portsmouth – ECD Architects

Further details on each of the above are provided below.

Jenny Stafford, Associate Director at Temple and Temple’s judge for the SECBE Awards, attended the judging day in April as part of a panel which judged the finalist for the coveted sustainability category. The category was strongly contested with the above projects demonstrating excellent and inspiring examples of embedding sustainability in construction.

Temple is again attending the awards dinner later this month where we will be presenting this year’s sustainability award to the winner. We look forward to celebrating with all finalists and winners on 28th June.

The shortlist of entries for the SECBE 2018 Sustainability category

25 Wilton, London – Kier Construction

25 Wilton Road is a refurbishment of structurally sound existing building a on a highly constrained site. The refurbishment performs both commercially and functionally in the same way as a new build and delivers strong sustainability performance including:

  • efficient design of building form, passive solar design, optimisation of façade and building envelope thermal properties;
  • high efficiency LED lighting which reacts to external light levels, high efficiency chillers, heat recovery mechanical ventilation;
  • CHP and provision for future connection to district heating;
  • BREEAM Excellent – final score 77.5%; and
  • smartwaste management on site, smaller deliveries, local materials suppliers, strong corporate responsibility action plan.

London Bridge Station Redevelopment Project – Network Rail

London Bridge Station Redevelopment Project is the lynchpin of the Thameslink Programme. It saw a sustainability agenda supported at the top of both the client and principal contractor organisations. Key sustainability achievements included:

  • a naturally ventilated concourse that does not require heating or air conditioning and creates as much natural lighting as possible generating significant energy savings;
  • intelligent control escalators that allow reduced energy use during station off-peak hours with annual savings of 36.46 tCO2e and over £9,000 in operational costs;
  • use of reinforcement steel with 98% recycled content that has delivered a 8,353 tCO2e saving;
  • transporting 200,000 tonnes of waste soil by barge resulting in 60% carbon emissions reduction compared to road transport;
  • development of an Operational Waste Management Plan which increased station recycling rate from 43% to 70-75%; and
  • CEEQUAL score of 94.2% on the station approach and estimated 95% on the main station; and
  • over 150 community engagements including 29 educational events.

Oxford Westgate – Laing O’Rourke

The ambition for Oxford Westgate was to deliver the most sustainable retail-led scheme in the UK, whilst ensuring the project remained viable.  A pioneering approach to whole life carbon saw the first 30 years+ of regulated, operational carbon emissions offset, something which had not previously been achieved before in the UK. Overall achievements included:

  • 28,700tCO2e  saved through design changes and lean, clean and green measures, equivalent to £7m of solar PV panels;
  • 98% recycled content for steel, cement replacement (GGBS), local sourcing for concrete (8km) and aggregates (23km), 100% recycled content in steel sheet piling;
  • over 98% of waste diverted from landfill;
  • centralised air source heating delivered heating and cooling to shops and restaurants avoiding use of natural gas;
  • digitally managed waste, digitally rehearsed construction. Laing O’Rourke and John Lewis challenged sub-contractors to reduce waste by estimating quantities and identifying minimisation measures;
  • supply chain sustainability workshop with Supply Chain Sustainability School and OxLEP; and
  • of the 65 targets, 45 were in the Sustainability Implementation Plan and 20 in the Employment and Skills Plan.

Principal Place, London Residential Team – Multiplex Construction Europe

Principal Place comprises a 50 storey residential tower, two further housing blocks and a landscaping scheme on the edge of the City of London. Multiplex, its consultants and subcontractors worked to achieve the following:

  • water and energy efficiency design in homes including fabric energy efficiency, rainwater butts, drying lines in bathrooms to reduce energy use associated with tumble dryers;
  • over 98% of all waste to date diverted from landfill, 100% of timber, concrete and steel to date responsibly sourced and 100% of water used during the fit-out works re-used;
  • subcontractor environmental workshops e.g. to support trade-specific sustainability initiatives and deliver waste minimisation effectiveness;
  • delivery of local employment, training, procurement and volunteering including 5% local workforce, 6 apprentices and redesign and refurbishment of the Gascoyne Estate Community Hub; and
  • construction and sustainability education initiatives with schools and colleges including resource efficiency in construction workshops and 490 hours’ worth of work experience placements.

Q6 Delivery Programme – Infrastructure and Aviation Business Unit – Mace Group

Mace is one of the four delivery partners for Heathrow Airport Ltd delivering Q6 projects, a five-year framework agreement which involves upgrading baggage system, passenger experience improvement and asset replacement work in Terminals 3 and 5. Key achievements included:

  • development of a prefabricated volumetric solution (Design for Manufacture and Assembly solution) for the temporary flight connections centre, maximising construction efficiency off-site with an optioneering exercise to explore re-use of the building modules;
  • prefabrication procurement which encouraged suppliers to manufacture and assemble most components off site;
  • continuous driving down of carbon, energy, waste and water consumption;
  • use of an electric-powered screed pump with zero operational carbon emissions on site;
  • the Huckerby Meadows restoration project undertaken with the London Wildlife Trust, Mace, Mace supply chain partners and Heathrow Airport Ltd which won Heathrow’s “Doing the right thing” award. This 13 hectare site near Heathrow’s first runway saw 1,700 volunteering hours. £30,000 was spent on repairing bridges, clearing seven skips of fly-tipped rubbish and eliminating invasive plants; and
  • Mace’s corporate commitment to RE100. Mace is one of the few construction company signatories to RE100 with the company committed to be “100% renewable” globally by 2022.

Wilmcote House, Portsmouth – ECD Architects

Wilmcote House is an 11-storey residential development in Portsmouth built in 1968. The structure comprised of large, poorly insulated concrete panels with pre-cast concrete elements that bridged the thermal envelope leading to high heat losses, internal condensation risk, mould growth and low internal comfort standards. ECD Architects designed and delivered a regeneration scheme with residents in occupation. Key achievements included:

  • sustainable low energy refurbishment built to meet the stringent EnerPHit standard, the refurbishment equivalent of Passivhaus.
  • the business case for the project demonstrated that over 30 years a deep, low energy refurbishment scheme was cheaper than decanting, demolishing and rebuilding the existing residential development. Payback and positive net present value was demonstrated after 19 years;
  • longevity of the existing community could be achieved given that the residents were not required to move out;
  • super insulation and fabric improvements mean space heating demand has been reduced from an average of 178 to 13 KWh/m2/year, representing actual savings of approximately 90% and in excess of £1,000 per dwelling per year over previous heating bills;
  • initial survey results from the last two winters show that the mechanical ventilation with heat recovery is providing a level of warmth which means heating is typically not required.
