Costs and Benefits

Energy Loans
The State of Oregon Office of Energy provided the project a $318,000 loan in support of its energy efficiency measures. Gray Purcell simply demonstrated in their application that the measures taken in the building would pay for themselves. Mike Purcell notes, "they (Office of Energy) turned the loan around in days…it was incredible."

The owners also received a Business Energy Tax Credit from the State of approximately $50,000 due to their anticipated LEED Silver rating.

LEED consultant Ralph DiNola points out that daylighting the basement was the most critical design move made in the project. "That building sat unoccupied for so long because nobody could make up a proforma that worked with the basement covered". Strategic interior design enables T·H·A to enjoy the well-known benefits of daylight such as reduced absenteeism, reduced energy consumption, and a comfortable indoor environment on both floors of the building.

LEED: Approximately 8% of the construction costs are attributable to LEED. This was considered about 3% higher than normal and was attributed to working with the existing shell.
