The central task of an appraiser who approaches a green and high-performance building is to assess its value, and, conversely, to identify any obsolescence factor (sometimes referred to as the "brown discount") of outmoded buildings.
The first sub-page of this section provides a repository of individual-building studies that have sought to quantify these sources of value.
The second sub-page of this section gathers reports of statistical studies on large populations of green and high-performance buildings, and provides a brief summary of findings for each.
The third sub-page provides illustrations of how green building rating tools can be been applied to actual buildings
The fourth sub-page provides documentation aids for the working appraiser.
