Embodied energy of lumber - 8.5MJ/kg.
Note that diesel has 36 MJ/kg. Thus - each kg of lumber contains about 250 grams of diesel used in its production!
Each wall panel of the Seed Eco-Home weighs roughly 110 lb = 4*13lb for studs - and a sheet of ply 60 lb - 3/4 total or about 1/2+3/8. Thus we have 110 or so lb. This is about 12 kg of diesel! Entire house walls (48 modules) thus have 576 gallons of diesel! About 20GJ.
Compare to CEBs - 1 gallon per hour - or 6*60=360 block per hour + another gallon for tractor for soil handling. Each 1' thick 4x8 foot wall section has 192 block or 1 gallon of diesel. 48 sections for SEH 1000 sf model thus have 48 gallons of fuel. Under 2 GJ.
