    1. 1. Practical SustainabilityApproach, examples and results of implementing carbon targets and“Sustainability in Design” early in AMP5 to reduce carbonBusiness Council for Sustainable Development Nov 2012Peter CaldwellLead Sustainability Champion@one Alliance (working with Anglian Water)

    4. 4. @one Alliance Board Commitment to Sustainability (Nov 2009) Environmental impacts • Focus on reducing energy, carbon and waste. • Drive innovative, sustainable solutions. Social impacts • Deliver with the local community • Develop training that enhances the skills of our workforce. Economic impacts • Work with the local supply chain. • Develop and implement a policy on sustainable procurement.4
    5. 5. @one Alliance Carbon Targets AMP5 Area Targets 2010 to 2015 Baseline is best practice in AMP4 / Ofwat submission. Embodied carbon reduction 50% Operational carbon reduction 20% Capital Expenditure reduction 20% rising to 30%5

Practical approach to Sustainability in Design Sustainability champions Sustainability examples SUSTA INA BILITY IN DESIG N EXAMPLE Ide a Re-design existing product to reduce embodied carbon by 50% Area WWNI Pro je ct Title Wastewater chemical dosing Ca teg ory Sta n d a rd Pro d u ct & G o od Pra ctice SEW/ WA T/ Pro duct Cod e Product 134b No . 3 Da te 31.08.11 (issue 3) Peter Caldwell – Ro ot ca use a n d d riv e rs An interdisciplinary team was set up to determine if a generic dosing product package could be developed Solu tion 29 schemes over AMP5 are due to be installed from 5m3 to 30m3 storage size of ferric, with the same Wastewater Non-Infrastructure for ortho or ferric or other materials dosing :- Root cause :- Carbon was not directly considered for basic control philosophies applied. This product is an update of the AMP4 product, but the original product. Can embodied carbon reduction with design reduced to the minimum required to be achieved? achieve the plant requirements.

Product reduced from 2 tanks and large kiosk to single self bunded tank and small kiosk. Smaller base and ancillaries for installation required. Still full assembly of units off site and simple installation Detail of any other particularly sustainability activity undertaken on the project.

    9. 9. Sustainability in Design Methodology Designers use a four stage hierarchy at the start of the project Build nothing Build less, Build clever Build with lower carbon materials Build more efficiently9
    10. 10. Build Nothing 1010
    11. 11. Build Less/ Build Clever • 30,000 population growth • Target cost £17m • Forecast below £15m • Embodied carbon - 65% • Operating carbon -120% • Effective OPEX saving over £230k/yr 1111
    12. 12. Build Clever/ Build with Lower Carbon Materials Conventional in-situ reinforced concrete Structured plastic with conventional bedding 34% cost saving 39% reduction in embodied carbon Precast concrete 28% cost saving 19% reduction in embodied carbon (50% reduction with cement replacement) Structured plastic in curved trench 38% cost saving 50% reduction in embodied carbon (55% reduction with SMR)12
    13. 13. Standard Products and Build off-site • Already off-site build in AMP4 • New single tank with reduced footprint • 40% reduction in embodied carbon • CAPEX savings forecast greater than 20% affordability • 29 projects will use this Standard Product13
    14. 14. Results for Carbon Driving Solutions Carbon modeller Carbon part of option selection and gateway governance Carbon performance tracked by team14
    15. 15. Conclusions Carbon targets used to change design and project behaviours. Practical examples generated. A step change has been made. Embodied carbon reduced significantly. Operating carbon reduced significantly. CAPEX, OPEX and whole life cost reduced beyond target15
