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

• 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
