RTEM/Continuous Auditing
Monitoring a facility in real time over the course of 6-12 months to identify immediate AND ongoing opportunities for Energy Conservation Measures (ECM).
▪ Perform initial energy audit
▪ Install circuit-level Real Time Monitoring system
▪ Track component-level Energy consumption over time
o Trained energy experts will investigate trends in real time
o Flag energy waste
o Identify and quantify new ECMs
o Track ECMs over time (before/after implementation)

When is a problem “Wicked?”
When it is difficult or impossible to solve because of:
• incomplete, contradictory, and changing requirements that are often difficult to recognize
AND
• efforts to solve one aspect of a wicked problem may reveal or create other problem due to complex interdependencies

Discussion of a “Wicked” Problem:
“How to optimally provide cleaner, morereliable energy services at lower costs?”
1. Rapid changes in grid value through EE, RE, connected… uncertain foundations for cost and returns; roles of stakeholders (utilities, manufacturers, policies, rates, etc.)
2. Role for Govt, Researchers, Vendors, Utilities, Implementers
3. When to lean into market interventions, when to lean back? (unhealthy markets, deadweight losses, customer “bill of rights”)
4. Strategies for wicked solutions: → Agile/Design+Systems Thinking
