Implementation

• Used initiative to focus morale and efforts during February 2009 when P&L and other economic indicators were unfavorable. Facilities could put forth extra effort to improve financial performance. We pledged a $1Million reduction in annual energy costs.

Team Dynamics• Used Production Agreements• Manage team performance by managing Glomixes• Munchized efforts to make progress every week.• Created measurement to validate success• Team included:

– AVP (Facilitator)– Directors– Engineers– Supervisors– Technicians

• All personnel had equal say. O&M could veto actions until they gained comfort with outcomes and risks.

Implemented Changes using Plan Do Check Act

• Brainstormed lists and used criteria to establish implementation order.

• Planned all implementations. Looked at both positives and negatives so contingency plans could be part of the implementation.

• Retested and modified as necessary to achieve desired outcomes.

• Created measurements for all changes.• Checked all results to meet expectations including any tenant

feedback.• Established low risk areas for all tests. Consistently used that

area for all new efforts.• Typically, there were three ideas in process at any time.• Did a lot of myth busting on many aspects of improvement.

These included turning off reheat in the cold duct of the dual duct air handlers.
