  • Built For Green Build Stroma Me And you….expectations
  • In the morning is introduction to concepts and posing of questions and ideas. In the afternoon we will translate these complex and competing ideas into practical, understandable and deliverable processes and solutions!
  • Sustainability isn’t new…in 1962 the publication of Rachel Carson Silent Spring bought it into the mainstream, but we still did litte…. Late 18 th century concerns were raised of agricultural productivity and population growth Mid 19 th Century George Perkins Marsh (1864) concluded that all past civilisations had collapsed because of natural resource demands exceeding the land’s ability to supply Over 200 definitions! Weaknesses in the definition are acknowledged “ Brundtland was a political fudge […] based on an ambiguity of meaning […] in order to gain widespread acceptance.” Definitions of sustainable development abound. There is some truth in the criticism that it has come to mean whatever suits the particular advocacy of the individual concerned. This is not surprising. It is difficult to be against “sustainable development”.
  • In order to have a healthy economy, we need a healthy society, which in turn relies on a healthy environment. That’s not what economists have been following for the last 100 years! Many other models Resource productivity: Factor Four (Lovins, Lovins and von Weizsacker, 1997): advocates a switch in focus from labour productivity to resource productivity if resource productivity could be increased four fold we could live twice as well with half as much The Natural Step In a sustainable society nature is not subject to systematically increasing: concentrations of substances extracted from the earth’s crust; concentrations of substances produced by society; degradation by physical means and in that society human needs are met worldwide” The Five Capitals Five capitals: Natural Human Social Manufactured Financial “ sustainability depends on maintaining and, where possible, increasing stocks of certain kinds of capital so that we learn to live off the flows (the ‘income’) without depleting the stock of capital itself; if consumption is at the expense of investment, or results in net capital depletion so that the capital stock declines, then such consumption so not sustainable and will be reduced in the future.” Sustainability in these terms is about Conservation of resources The protection of capitals for people’s use The consideration of future generations Fairness in the access to goods and services Engaging in a process of consultation and inclusion
  • Energy gap created by UK power station closures as predicted by EDF….shows the predicted capacity of UK power stations in kwh per day per person. This is why the government was pushing ahead with their massive nuclear plans. Changing planning policy to make it easier to build the power stations. And then Japan happened….so what now? Since 1993 we have been an energy importer and our energy comes from some of the most politically challenging states. Gas from Russia…oil from the middle east Rate of oil extraction has exceeded rate of new finds in decades Gulf of Mexico disaster – what were we doing ther in the first place? Biggest environmental catastrophe…social impacts are ongoing
  • Specific, Measurable, Agreed Upon, Realistic and Time-based
  • Later developed into more smart targets. For example biodiversity became delivery of 45ha of biodiverse habitat.
  • The T-shaped professional – for innovation and change An alternative in your profession might look like this….it is ultimately what the structure and subsequent engagement was trying to create – a structure where everyone understands their contribution to sustainability and is able to commit to that through developing their own skills and job function.
  • 3million includes 1millionm3 follow on contractor arisings 600,000 m3 transported off site to landfill, half of which was too contaminated – soil wash waste and japanese knotweed, remaining 300,000m3 not clean enough for reuse as capping landfill. No time to reprocess, missed opportunity with 300,000m3. However still gives 80% reuse compared to industry average of 30-50% reuse
  • Additional 100,000tonnes for engineered fill (soil remediation provided an additional 500,000m3 of engineered material) Only 10,000tonnes of material recycled offsite. Concrete, mixed masonary, asphalt, timber all recycled and reprocessed on site
  • Engineers taught to specify ‘Type 1 materials’. Expensive and often require import. With a little outside the box thinking innovative solutions can lead to massive sustainability wins and cost savings Galvanised steel straps and baskets Drainage layer replaced with plastic straps temporary structures straps ‘beefed up’ Upper phi angles for deflections compressible board 600,000m3 of material in all used for engineered fills in one form or another
  • Reclamation and demolition process promoted highest value use of materials…
  • What can be used to substitute primary components of concrete? Recycled content vs embodied energy? On site batching plant supplied over 315,000m3 of concrete to date cement has 820kg/tonne embodied CO2 GGBS 89kg/tonne and PFA is and 30kg/tonne however replacements are up to 70% and 40% respectively Stent slightly higher embodied energy due to distance travelled. Challenge to get contractors to feel comfortable in using it. 76%secondary aggregate, 40% GGBS… Over 3,000 tonnes of excess gas pipelines used for Stadium and Velodrome compression trusses (equivalent to the steel in the Aquatics roof!) 1 year Park operation 12,000tonnes (50% energy reduction gives 6,000tonnes)
  • Foammix Initiative too late gain acceptance to construct permanent roads
  • Malcolm story re hoarding paint Watsons… You don’t talk VOCs, you tell site operatives if you’re using something that smells bad ask your supervisor if there isn’t an alternative Watsons story
  • Commercial team is important!!! Asking the right questions of the supply chain at the right time yields great results! Importance of Commercial team involvement Communication of requirements prior to (sub) contract award
  • Holorib used for upper floor construction minimises depth; reduced amount of concrete (56% less concrete), resulting in 330 tonnes of waste being avoided. Off site construction of toilets (all cut-to-size). Typical waste savings through MMC toilet pods is 70 -90% compared to standard practice. Reuse vs recycle… Although new steel sections are made with 60% recycled content they still have 25 times the environmental impact of reclaimed and reused steel sections. Use of reclaimed timber is estimated by BRE as having a 79% lower environmental impact compared to new.
  • Velopark is currently achieving over 35% better than Part L, mechanical cooling has been eliminated (cooling is still required to keep the track at the correct temperature for optimum speed!) Increased specifications on insulation and U-values
  • 73% water reduction in MPC, high spec offices with non-potable water for toilet flushing and waterless urinals Not the prettiest of buildings – suffered from the downturn in the market, private investment fell through, had to be met from Project contigency.
  • Olympic Park have a rail head (this will operate in Legacy) and more recently a wharf to handle 350tonnes barges. Required significant investment in a new lock and protection of bridges Bulk quantities only. Cost vs storage. Protection of units during transport Other opportunities foammix plant at Bow East Logistics Centre 900,000tonnes of aggregate, 90,000tonnes of components. Over 8,000tonnes of CO2 (that would power the demand reduced Legacy Park and Venues for over a year) and 50,000 road movements eliminated
  • Importance of knowing my KPIs so I can evaluated performance against them. Not all benefits are easy to quanitfy BUT I need all the inofrmation to make my decision…

    20. 22. Group Discussion It’s too late to try I’m too small to make a difference I’m too busy to bother with this We need to take this one step at a time If we can get this right, there’s a massive opportunity out there
    21. 23. Setting out on the Sustainable Path Reframing the problem What needs are being addressed? What are the benefits, and who stands to gain? What are the costs, and who stands to lose? To what spatial and temporal extent should we consider the impacts and benefits?

    26. 28. Setting out on the Sustainable Path Why does it not work better? <ul><li>By externalising the internalities in a system, the consequences can be exported to others </li></ul><ul><li>By setting narrow boundaries to a system the true impacts of a proposed project are masked, or ignored </li></ul><ul><li>By failing to incorporate the time dependent consequences of a proposed project, the long term impacts are omitted </li></ul><ul><li>By limiting the responsibility of the individuals in a process the defence of “it wasn’t my job to consider that” can be invoked </li></ul>
    27. 29. Group Exercise The drawing of tight boundaries around systems or projects gives a false impression of impacts and compromises sustainability <ul><li>Select a project: Three Gorges Dam in China, Hydropower from the Severn Estuary, burning of waste tyres as a fuel in cement works , or…. </li></ul><ul><li>Consider: </li></ul><ul><ul><li>System / Project boundaries </li></ul></ul><ul><ul><li>How can needs be defined? </li></ul></ul><ul><ul><li>How do we allow for future generations? </li></ul></ul><ul><ul><li>How much should we leave for them? </li></ul></ul><ul><ul><li>Who should be involved in decision making? </li></ul></ul><ul><ul><li>How should natural environment be protected? </li></ul></ul><ul><ul><li>How do we decide how to share resources now? </li></ul></ul><ul><ul><li>Should people accept a reduced standard of living? </li></ul></ul>
