Periodic refurbishment and reductions in national costs to sustain dwelling services

摘要

This paper uses a simulation model to make exploratory estimates of current and potential reductions in national costs to sustain dwelling services due to refurbishment. Data and parameters are based on a typical New Zealand dwelling of lightweight timber framed construction. Dwelling service years provided by a Dwelling over one year adjusted for depreciation serve as a proxy for benefits. The costs to construct one Dwelling and fractions thereof serve as a proxy for the costs of maintenance, refurbishment, replacement, And new construction.
