The Stride Treglown Retail team worked closely with Sainsbury's to benchmark, create objectives, design and achieve results which made Sainsbury's Dartmouth a flagship low carbon store.

The team's was asked to achieve a 30% reduction in Operational Energy and a 25% reduction in Operational carbon, whilst measuring the embodied carbon footprint of a standard 20k store and to reduce it by 20%. They were also tasked to produce at least 20% of energy used on site using renewable sources and to achieve a 40% reduction in overall mains water consumption.

The team successfully achieved a 40% reduction in Operational Energy, a 35% reduction in embodied carbon, a 30% reduction in lifecycle carbon and the store scored a BREEAM 'excellent' rating of 71%. There was also a 60% reduction in water consumption and site waste recycling at 91%.

Stride Treglown's expert Retail team utilised local materials where available and BRE Green Guide (A and B rated) and to maximise the use of recycled materials during construction, diverting at least 90% of construction waste from landfill.

The team also eradicated as far as practical, all environmental pollution caused by the store in terms of surface water, greenhouse gases, noise and light whilst maximising landscape opportunities to make a contribution to the local urban environment. The store is further supported by a green travel plan which minimise the environmental impact of transportation to and from the store.

Key successes include:

  • 82 x sunpipe rooflights 76 tCO2e saved per annum with night blinds to reduce night pollution
  • 21% uplift in cost v steel from a timber frame structure [107 tCO2e savings v steel] using traditional lime render, heated treated FSC timber
  • Broag wood pellet boiler 164 tCO2e saved per annum
  • 2 x 21 Quiet Revolution wind turbines [8 tCO2e saved per annum] with 6m/s wind speed generated = 14,400 kWh per year
  • Rainwater harvesting, waterless urinals, 4.5 litre cisterns to w.c's

A dedicated drop off lay-by is proposed, together with a new bus bay within the site. The site layout sets out secure routes, with sheltered external waiting areas, within easy reach of the drop off points for parents seeing their children into either the main playground or the quieter Early Years play space.

The scheme minimises its impact on the site whilst maximising the possibilities for creative outdoor play and stimulating teaching areas.
