Model Description

Model Form

• This model produces the lifecycle global warming potential of a building at a fine level of detail.
• Extraction and manufacturing phase
$$GW{P_{EM}} = q\sum {{i_{gp}} + {i_{gt}}d} $$
• On-site construction phase
$$GW{P_{OC}} = {E_{OC}}{i_{gc}}$$
• Operation phase
$$GW{P_{OP}} = {E_{OP}}{i_{go}}$$
• End-of-life phase
$$GW{P_{EoL}} = {E_{eoL}}{i_{geol}}$$

DDM sensitivities

• No
