  • Most of the time the “diverse group” outperforms the “group of the best” by a substantial margin.Lu Hong and Scott Page in Proceedings of the National Academy of Sciences (2002)

Carbon Life Cycle – Data structure Design Materials or Product Manufacture Distribution Assembly on site In use Refurbish/ demolish Embodied carbon – •Resource extraction •Transportation, manufacturing and fabrication of a product (typically ‘cradle-to-factory gate’). •Can include energy used during the design and end-of- life stages Operational carbon – Emissions from energy consumed once the building is occupied; • lighting, •Heating, •cooling, •ICT. Construction carbon – •Construction site machinery •Site huts •Transport Accuracy levels + /- 20-30% + /- 5% + /- 15%-70% 1-2%Total Emissions 15-30% 3-4% 5-6% 50-70% 2-4% Source: IGT/F+G 10
    11. 11. a “Carbon Footprint or Carbon Profile equals the overall amount of carbon dioxide (CO2) and other greenhouse gas (GHG) emissions (e.g. methane, NOx, etc.) associated with a product along its supply-chain, including use and end-of-life recovery and disposal….. “ 11
    12. 12. Definitionused in UK constructionindustry 12 • Embodied carbon – the sum of fuel related carbon emissions (i.e. embodied energy which is combusted – but not feedstock energyretained within building material) and process related carbon emissions (i.e. non-fuel related emissions which may arise, for example, from chemical reactions).” The Inventory of Carbon and Energy (ICE V2.0) as published by University of Bath, January 2011
    13. 13. Carbon counting To use this data you need to measure the weight of the different materials in a building. There are two options for using the data: 1. Transform it into values for products in the units in which they are procured and use existing estimating measurement rules. 2. Produce a database to estimate weights of materials which may need a whole new set of rules of measurement and procedures 13

    19. 19. In Praise of Experts? Theorem: If an expert can integrate every variable considered by any one of the novices, the expert predicts better than the crowd of novices. Else, the crowd of novices will prevail.
