Expanding on the concept that most buildings can achieve 10-15% annual energy savings through behavioral and operational improvements. Public Service Company of Oklahoma (PSO)’s Energy Coaching Program assisted customers to find a variety of ECMs resulting in high energy savings with low effort/cost measures using 15-minute interval data from AMI meters. The program fully leveraged AMI data an underutilized utility and customer resource to show how “big data” can simplify energy management conversations with customers and ultimately reduce energy intensity of buildings. PSO partnered with Trane and deployed their Energy Optics tool to create new insights on building performance by creating reports, consulting with customers, and providing ECM recommendations based on the customers’ business needs and budgets. The tool provided customers with 3D load profiles that contained 35,000 data points per year giving building owners a quick “MRI” snapshot of their operations. These profiles helped customers find excessive energy usage during occupied and non-occupied hours, identify high demand times, and benchmark daily energy usage to find best performing days. The program helped customers discover and implement a variety of ECMs which included: schedule optimization, OAT reset, duct pressure optimization, and equipment optimization. The program provided 57 customers with Energy Coaching reports that resulted in four GWh savings. These savings were also measured and verified using the Energy Optics tool once the ECM was implemented. The presentation will highlight three different case studies (church facility, K-12 school, and office building) and provide an overview of the lessons learned.
