PERFORMANCE OPPORTUNITY EVALUATION PROCESS

ESI's Performance Opportunity Evaluation process outlines the benefits of controlling operating costs, including energy, personnel, facility, maintenance, and business sustainability as well as improving peak performance of key stakeholders across the organization.

A paradox - in today's buildings there is a similarity of efficient equipment between the lowest and highest performing buildings which challenges a longstanding misconception that building efficiency can be defined by the presence of efficient equipment. Certainly energy-efficient equipment significantly contributes to whole-building performance, however, problems with energy efficient equipment is frequently a primary source of energy inefficiency.

Numerous studies support this assertion. In a 60 building study, Lawrence Berkeley National Labs found that 50% of the buildings had control problems, 40% had HVAC equipment problems, and 25% had EMS, economizers, and/or VSDs that were not functioning properly.

ESource documents a study which estimates failure rates of economizers of 50% and higher, with the resultant energy waste far exceeding the achievable energy savings from properly working equipment.

Other studies on oversizing, poor system integration, operator error, and poor commissioning and maintenance also illustrate the potential energy waste from energy efficient technologies. Just as incorrectly deployed efficient equipment is not the sole cause of a low performing building, efficient equipment alone is not an indicator of a high performance one.

Energy usage goes beyond the HVAC arena to lighting, communication, fire and security. All are the key contributors and therefore were included in this analysis.

By coupling this with the concept and benefits of engaging all stakeholders in the process, you'll increase employee ownership of corporate energy management. Finally, by leveraging technology and services in this way you can cut operating costs dramatically, but also improve your competitive position and drive top-line revenue.

The Methodology

ESI knows the value provided by a best practice use of facility automation and energy conservancy tools and processes. We live-and-thrive in the world of metrics.
ESI's Performance Opportunity Evaluation process is a proven and repeatable process that verifies how to optimize building performance creating efficiency, reducing costs and increasing revenue.
