  • Contribution of material manufacturing stage has exceeded 80% for global warming, ecotoxicity (terrestrial) and urban air pollution.
  • Contribution of the assembly stage was about 60%, or a majority, for exhaustion of waste displosal sites and water resource consumption.
  • No clear influence was noticed for depletion of the ozone layer in the computation conditions this time.
  • Influence of transportation stage and disposal stage was small in all environmental domain of influence.

Comparison with previous product (Global warming)

  • Environmental influence reduction rate for new products was 7.4%.
  • Decreasing the weight of trusses and beams was the main contribution to the reduction of environmental influence.
