Continuous Optimization Program Overview
Description
• The Continuous Optimization program targets operational savings in the commercial sector
• The program consists of two primary components– Retro-commissioning– Energy Management Information System
Description (Continued)
• Positioned as a commercial sector “Monitoring Targeting & Reporting” program.
• Program offer:– Fully funded retro-commissioning study– Fully funded EMIS– Customer implements bundle of measures
up to 2 year simple payback
Energy Management Information System
• Most important aspects of an EMIS:– Measurement & verification– Exception reporting
• Customer response to date to program offer

Pulse Energy’s Role
• Most buildings are in need of commissioning
• Energy consulting and retrofits are important, but usually slow and expensive
• Focus on energy information & analysis enables quick action with measurable results
Lessons Learned from BC Hydro Continuous Optimization Program
• Energy managers are key program leaders – often facilities managers are focused on other priorities
• Customers appreciate a turnkey solution that provides advanced energy use information
• Utility programs must have resources in place to walk customers through the initial gap analysis and program implementation
• Starting quickly with small simple steps is important
Lessons Learned from BC Hydro Continuous Optimization Program (Cont’d)
• General lack of sufficient measurements of green retrofits
−Building owners who don’t have systems in place to effectively measure performance will lag the market and incur additional costs
• Lack of trained energy efficiency engineers is a constraint to the pace of commissioning programs

Challenges and Opportunities in M&V Today
Sources: Green Building Retrofit & Renovation, McGraw Hill Construction; Pulse Energy research
• Manual calculations make it difficult to do an “apples to apples” comparison of baseline and performance periods
• Off-the-shelf software technologies offer big improvements in operational efficiency for a minimal investment
