LBC Financial Feasibility
borrowed with permission from Cascadia GBC
Radically affects the payback period.Incentives are critical.
Institutional clients build high quality, long life buildings. Initial budget for base building higher, increment to Living Building is lower.
Cost of Energy + Water
Client
Extremes in temperature.Amount and regularity of rainfall.
Climate
User actions + interface will be critical.Willingness to adapt / change behavior.Client / Occupant buy-in and advocacy.
Area’s building culture affects willingness to pursue bleeding edge green.Designer’s past experience.Contractor’s past experience.
Occupants
Team Familiarity
First costs are much higher for small and very small buildings.Floor area to roof area ratios radically affect PV and water collection.
Size Does Matter
The Big QuestionsPragmatist vs. Idealist
The regionalization of building economies
Support of USGBC
Regionalizing Economies
Diversified manufacturing
A flourishing of regionally appropriate design solutions.
Would regions develop carrying capacities?
