Company Summary

The Green Book Value (GBV) tool is the Kelley Blue Book (KBB) for energy efficient homes. Similar to the KBB, the GBV allows homeowners to input information about their home’s efficiency, such as increased attic insulation levels or a premium-quality furnace, which can be passed to their Realtor and ultimately an appraiser at time of sale to provide a higher valuation based on the higher efficiency levels of the home.
