4. The user is able to override the thermostat setpoint on a temporary basis; the<br />
temperature reverts to the programmed setpoints after a few hours. The<br />
deadband remains the same as the setpoints are adjusted.<br />
5. The DSP reset installed was based on OAT, without putting WPT zone information<br />
to use to optimize the reset. Thus, this measure was not enabled by the WPT<br />
installation..<br />
6. Global temperature adjustment for demand response was not implemented due<br />
to a non-WPT related integration issue.<br />
7. Automated demand response (ADR) was implemented at the site concurrently<br />
with this project. ADR measures include a DSP reset, economizer reset, and CD<br />
SAT reset.<br />
8. The site had intended to go forward with adjusting optimum start programming,<br />
which would have contributed to scheduling measure savings, but they were met<br />
with resistance from building operators. We cannot speculate as to if the planned<br />
optimum start measure would have incorporated information from the WPTs. Our<br />
monitoring data showed that no scheduling changes occurred.<br />
MEASUREMENT AND VERIFICATION (M&V)<br />
MONITORING PERIODS<br />
Pre-WPT retrofit: 11/10/2011 to 12/5/2011<br />
Post-WPT retrofit: 6/5/2012 to 6/28/2012<br />
EEM-1: CD SAT RES<strong>ET</strong><br />
Visual Inspection:<br />
We verified the implementation of the CD SAT reset through BMS screen shots.<br />
