EDGE Cost Model

Supplementing the EDGE Methodology Report, the EDGE Cost Model outlines the general overall methodology followed by EDGE to create the cost database used in incremental cost calculations. The document discusses some features that will only be available in Version 3.0.0 of EDGE. Incremental cost calculations are intended to provide a sense of comparative costs rather than definitive cost estimates. The calculations integrate the impact of all options. For example, an upgrade to lighting or windows might be offset by savings from a smaller HVAC system, which can at times even produce a negative (-) incremental cost.
