Readiness check

Is your building tuned or just drifting?

Retro-commissioning is the highest-return energy work because it tunes what is already there, mostly with no-cost and low-cost fixes, instead of replacing equipment. But buildings drift, so the savings only last if you test the drift, fix it, and keep monitoring. Answer for how your building is actually managed. This is general guidance; confirm with ASHRAE and a commissioning authority. The score stays on your device; enter an email only if you want the retro-commissioning checklist sent over.

1. Has the building ever been commissioned, or is it running on never-tuned controls?Yes, commissioned and re-checked sinceCommissioned once at construction, never sinceNever commissioned

2. Do you suspect or see drift (overridden setpoints, bypassed schedules, controls in manual)?No, controls are clean and verifiedProbably some drift we have not checkedLots of overrides and manual controls

3. Do you use BAS trend data to find where the building wastes energy?Yes, trends surface the driftWe have a BAS but rarely trendNo trend analysis

4. Do you functionally test systems (economizer, resets, staging), not just trust the BAS screen?Yes, we test what the systems actually doWe trust the BAS graphicsNo functional testing

5. Are the common wasters checked (economizer, simultaneous heating and cooling, schedules)?Yes, the usual culprits are checkedSome of themNot checked

6. Do you fix the no-cost and low-cost operational items first, before capital?Yes, operational fixes firstWe mix it with capitalWe jump to replacing equipment

7. Do you verify the savings with M&V after the fixes?Yes, M&V proves the savingsWe assume it workedNo verification

8. Is there ongoing monitoring so the building does not drift back?Yes, monitoring-based commissioning keeps it tunedWe fix it and walk awayNo monitoring
