INCENTIVES<br />
The site received two incentives for a total incentive amount of $117,189.<br />
Customized Retrofit Incentive: The CRI program savings amounts are listed in the table<br />
below. The CRI program incentive was $26,971.<br />

Oakland Shines: The savings amounts from the Oakland Shines program are shown in the<br />
table below. The savings amounts were based on spreadsheet calculations. The Oakland<br />
Shines program incentive was $90,218.<br />

COMMENTS AND OBSERVATIONS FROM SITE STAFF<br />
The owners are happy with the system. They expect to see savings in reduced<br />
energy bills.<br />
Tenants have found the temperature more consistent. The building management<br />
staff has already noticed receiving less complaint calls, and is able to check<br />
temperatures and operation centrally before going to the problem zone.<br />
The installation process (units on the wall) took longer than they had thought, more<br />
than 2 days per floor.<br />
The installation process generated a punch-list of 40 boxes to check in the building.<br />
This was seen as a benefit to the installation allowing problems to be identified<br />
(although maybe not for the building engineer who has to do the repairs).<br />
Unit installation was estimated at 3 to 4 weeks out of a total project length of 6<br />
weeks to 2 months.<br />
At the time we discussed it with them, the building staff had not addressed having a<br />
controls contractor on a maintenance contract. However, they suspected that they<br />
would use the WPT installation contractor for any future controls work.<br />
They would like to pursue LEED® certification next year.<br />

This site selected single setpoint thermostats, and it would be cost prohibitive to replace<br />
these with deadband models at any point in the near future. This site could potentially<br />
modify the SAT reset to be based on actual zone temperatures, rather than on average<br />
building temperature.<br />
