3 Concrete Blocks Topics to cover  Supply  Thermal Bridging – CBA Details  Sustainability …then lunch

4 The Market Govt. Initiatives Response

5 Capacity Quicker response ? Post recession Output of the industry How can manufacturers respond? Re-open moth balled plants Extended Working Hours Speed-up curing regimes Build winter stock levels

6 The Market Its not rocket science!! It’s a concrete block

7 The Market

8 New Output

9 Concrete Blocks Topics to cover  Supply  Thermal Bridging – CBA Details  Sustainability

10 Concrete Blocks Are greener than you may think Cements Content only 9% * 1 19% of above are ‘alternative’cement’s Aggregates are often ‘surplus’ dust from quarries Blocks can be 100% recycled aggregate * 1 WRAP Resource Efficiency Action Plan

11 Concrete Blocks Embodied Energy 6Kg CO 2 /t blocks * 2  That is 7 times less than softwood  That is 30 times less than steel  That is 40 times less than plastic * 2 Uni. Bath Inventory of Embodied Energy 2008 (Excludes Calorific Value of wood) Are greener than you may think

12 Concrete Blocks Manufacturing waste is re-used (WRAP) Energy used in manufacture only 21kW.hrs/t Less than 2% wastage on site Delivery average 60 miles from 100 plants across the UK Are greener than you may think CO 2 Footprint does not need to measured from the Port of entry

13 Localism Local Supply Local Plant Local Materials Local Labour

14 So why Concrete Blocks? Off the shelf Ease of use BRE Green Guide A / A+ Recyclable on site to granular Traditional Known Practice Building Reg Compliant Competitive build cost Made locally
