What does changing the life cycle years do?
Changing the life cycle years changes the number of years over which costs and benefits for the site are calculated. Each infrastructure component is assigned a lifespan, so for example, a 100 year life cycle analysis may include the construction cost of the concrete sidewalk and driveway (30 year lifespan) four times. Different life cycle analysis periods are useful for different reasons, for example the 100 year analysis is useful for comparing green infrastructure options to traditional stormwater infrastructure, while the 30 year analysis is useful for considering green infrastructure investments in terms of the average mortgage length.
