48. Athena eco calculator
•Excel spreadsheet
•Simple geometric form
•Limited construction options
•Limited to US and Canadian cities
49.
50. Athena eco calculator
•Not take into account site
•Approximations
•60% of modified ICE result
•Covers more LC stages
•Influence of location unclear
53. Athena Impact estimator
•Specialist software
•Custom constructions
•US and Canadian cities
•Includes operational energy
•Can change lifespan of building
54.
55. Athena Impact estimator
•400mm limit on constructions
•Less categories than Eco calculator
•Operational energy calculation simple
•Operational energy annualised only
•900% less than ICE database
63. Basic freight modelling calculator
•On line calculator
•Enter weight of goods
•Enter distance travelled
•Framing timber taken for building from
Canada
64.
65. Basic freight modelling calculator
•Weight not only criteria volume, length
•Crow flies distances not applicable
•Not clear where materials come from
•Distribution centres and middle men
•30% higher than RICs data on materials
transport
68. Eco transit
•On line tool
•Source and destination entered
•Trade routes established
•Calculation on weight and container used
69.
70. Eco transit
•Similar results to Freight calculator
•Established trade routes not given
•Distance 50% higher than freight
calculator but 80% of result
•More significant than RICs figure
73. IES-VE SBEM sketch up plug in
•Sketch up
•Limited amount of information
•US based constructions
•Substitutions required for domestic use
74.
75. IES-VE SBEM sketch up plug in
•Single answer recalculated quickly
•Specialist model required
•650% of SAP figure
•Material selections and energy sources
78. WRAP net waste tool
•On line tool
•Minimal data
•All items constructed on site
79.
80. WRAP net waste tool
•Benchmarking tool
•Granularity not for a house
•Little advice given
•Data on wastage per material type would
be useful range of figures
83. Zero carbon waste Scotland
•Excel spreadsheet
•Quantities based without mistakes
•Categories are tight so assumptions made
84.
85. Zero carbon waste Scotland
•Great deal of number manipulation
required
•No evaluation of results
•Benchmarking difficult on small scale
•Wastage scenarios can be evaluated only
across different spreadsheets
