Prescription for Energy Savings Written for Large, National Drug Store

ATLANTA, GA - May 30, 2007 - Prenova announced today that it signed an energy management contract with a national pharmacy retail chain for Asset Optimization. Prenova begin its Asset Optimization solution to all retailers stores equipped with energy management systems (EMS).

With the pharmacy chain’s goal of reducing energy-related costs by 25%, the first step in doing so will include Prenova’s Parameter Standardization Program (PSP) and a one time VirtualAuditSM to over 400 stores. The PSP is a diagnostics program that analyzes and reports on those assets at each site that are operating out of the range prescribed by the pharmacy retail chain’s business operating standards. This program operates through a remote connection to the retailer’s EMS. With their approval, Prenova will implement automated resetting of compliance parameters at all sites in the program to maintain business operations and optimize energy consumption.

Prenova will then apply its VirtualAudit tool, which creates a baseline of asset performance by identifying and prioritizing relevant factors driving any suboptimal asset performance. The process also includes a methodology for estimating excess energy consumption due to identified suboptimal performance by identifying early asset degradation patterns and root causes for that degradation. The VirtualAudit tool incorporates Prenova’s capability to remotely correct identified issues when possible, and to work with on-site technicians when required to ensure service maintenance quality assurance.
