10. 1. Continuously benchmark facility energy use 2. Prioritize facilities  Heavy usage  High public visibility 3. Conduct energy assessments 4. Self-manage retrofits, quick payback first 5. Measure & verify utility savings (avoided cost) 6. Revolve energy savings and rebates  Comprehensively retrofit all facilities 10

11.  Develop in-house expertise  Train building operators; preventative maintenance  Install control systems your staff can operate  Exercise a robust compliance protocol  Quality control and field verification is essential 11

12.  Benchmark all buildings with significant energy use  Measure & Verify utility savings (in-house)  Large portfolio: whole building utility bill analysis, IPMVP Option C  Follow life-cycle for capital-intensive upgrades  Commission or functionally test every project  Simple Solutions: Set points, operating hours, equip. right-sizing 12

13. 13

14.  Budget is war: Know thy CFO, budget director, & budget analyst  Tell the full fiscal impact of your work:  Reduced energy costs  Accomplished deferred maintenance projects  Reduced operation and maintenance costs  Review bills monthly & know thy rate categories  Exercise fiscal temperance with savings  Incur no debt & always be cash-positive 14
