Model Description

Model Form

• This model produces the lifecycle water usage in a building at a coarse level of detail.
• Entire lifecycle
$${W_{LC}} = {n_s}{A_f}({w_{pud}} + {t_d}{w_d})$$

DDM sensitivities

• No

Properties

Object Name

• Name of the object in Rt
• Allowable characters are upper-case and lower-case letters, numbers, and underscore (“_”).
• The name is unique and case-sensitive.

Display Output

• Determines whether the model is allowed to print messages to the Output Pane.

Pre Use W Intensity

• \({w_{pud}}\) = The water intensity of the materials used (pre-use) for a corresponding building function in L/m²

Number Storeys

• \({n_s}\) = The number of storeys in a building

Footprint Area

• \({A_f}\) = The building footprint area of building in m²

Annual W Intensity

• \({w_d}\) = The annual water intensity for a given building operation type in L/m²/year

Design Life

• \({t_d}\) = The design life of the building in years

Output

• \({W}\) = The lifecycle water usage in a building in L
• The output is an automatically generated generic response object, which takes the object name of the model plus “Response”.
