•  Resource Efficient Design is increasingly needed to: –  minimize the 109m tonnes of waste the UK

construction industry generates each year, –  avoid shortages in the future (it is reducing) –  enable reuse of all materials at the end of life.

•  Brian Murphy will introduce a set of adoptable design principles and illustrate them with examples of their implementation and introduce sources of information.

Resource Depletion

•  Depletion of our Finite Resources •  Our natural resources such as:

–  energy, water, food and raw materials –  are becoming increasingly scarce and

expensive –  due to the effects of

•  population growth •  increasing expectations of wealth seekers •  Resource intense production and distribution •  Finite resources •  climate change •  restrictions imposed by resource-exporting nations •  greed for market share and turn over by retailers •  wasteful methods of production, sales and use

•  In the news •  50% of food production is wasted •  Halal meat contaminated by pork

–  Destroyed but could have been fed to non-halal eating population

•  Beef contaminated with horse: destroyed –  Better than connective tissue, fat, salt, sugar? –  We eat baby sheep, chickens, fish why not

horse? •  Vet drugs contaminated meat in food chain •  Toxins in the oceans contaminate marine

food chain, •  highest contamination in whales 14/02/16 6

Resource Security Action Plan

•  UK Government produced one •  but is it doing enough to promote it? •  Are businesses independently developing

initiatives to address resource efficiency and life cycle management?

•  Are we moving towards waste being valued as a resource?

•  What measures should be taken to provide energy, water and food security?

•  http://services.lawsociety.org.uk/events/node/54729 14/02/16 8

Design generates waste

•  Waste reduction is not a site issue –  It is a Design Issue

•  It becomes a site issue –  if is was not seen as a Design issue

•  Join in now or – D&B takes another % of UK procurement – And probably waste some more resources

•  7 billion and counting passengers •  All want to live a European lifestyle •  Europeans live a 3 planet life style •  We only have one planet •  We need to adopt a one planet lifestyle •  We all want cars, fridges, mobile phones,

computers, entertainment centres, •  instantaneous responses and no

responsibilities •  Finite resources: running out fast •  Or adoption of renewable resources 14/02/16

•  Peak Oil –  Fuel Poverty (heat first: coolth & power next)

•  Peak Fish –  Food Poverty

•  Peak Pollinators? –  Bee populations (cause? not sure yet) –  Peak Crops

•  Peak materials –  Peak finite materials, fossil based

•  Renewable materials: during our life •  Rapidly renewable

–  seasonal, yearly, short crop rotation, •  Competition for land and sea 14/02/16 19

Resource Autonomy

•  Fuel Security & Materials Security –  Reliance upon the rest of the world to share

•  Money can buy anything –  if it remains affordable

•  Force can get a lot –  but it already bites back

•  Abundance prevails –  The sun is sharing its wealth freely –  We could have some of that

•  Autonomy is probably possible –  But we can make strides –  The will is not there yet –  EU is pushing but UK are still resisting –  And now we consider getting out of the EU 14/02/16 27

‘Commercial Green’

•  Promotes the idea that some technologies are not affordable now and may not be appropriate for some decades

•  We should rationalise the technologies and prioritise those to be used now, in 10, 20, 50 and 100 years

•  (assuming we are still here after 2050)

Mind Maps

•  Gifford have a number of mind maps •  The following is the first •  Inspired by early Archigram work •  They have more, but despite NGS

attempts they do not want them in the public domain via NGS

•  One day we hope they will bring them to the market themselves

Renewable Everything

•  Grow it yourself •  Grow building materials •  Grow them quickly •  Sequestrate carbon in the process •  Store carbon •  Then reuse it after its been a building •  As another building? •  ASBP promote renewable materials

Resource Management

•  Site activity is not our concern •  But you designed the building chose the

methods of construction and chose the materials

•  If that combination is wasteful then we should concern ourselves about it

REAP Resource Efficiency Action Plan

•  WRAP and BRE responsible for setting up and driving REAP in all the sectors

•  Flooring, Ceilings, Linings, etc. •  FSP Flooring Sustainability Partnership

– Runs the Flooring REAP – CFA Contract Flooring Association et al – Training of buyers and installers to focus

on RE and give voice to talk up supply chain – Calculators for waste – Attempts to get CSkills funding: faltered – Going after WRAP funding now

Resource efficient v Resource effective

•  Cradle to Cradle •  Trying to get the best out of what we

already do •  Or •  Radical rethinking of what we do •  To get better results from the outset

Design to Reduce Waste

•  33% of 100m tonnes/per annum wasted is offcuts (UK Construction Industry)

•  Offcuts because we don’t design with the manufactured sizes in mind

•  Or we don t care how much we waste •  We think waste reduction is a site issue
