A good way of understanding the purpose of the energy performance score is to consider a similar metric for cars. The MPG rating on a car helps you and I understand the fuel efficiency of a car. Right now, most energy consultants or engineers use kbtu/sf but it is not sufficient. Many building owners, managers, and facility professionals couldn’t answer this basic question about the performance of an office building. That’s why the EPA score was created.
August 2010 – 140,000 buildings rated
August 2010 – 11,600
In California, the recent Assembly Bill 1103 creates a program that begins by requiring utilities to make customer usage data available electronically on request for use in Portfolio Manager. As of 2011, the requirement becomes mandatory over a three-year phase-in for disclosure of energy performance data when a building is sold, leased, or financed. After the passage of AB 1103, the legislature passed AB 531 to give the CEC the authority to draft regulations for AB 1103 implementation. An important part of those regulations is the implementation schedule for AB 1103, currently in draft form, which treats owner-occupied and tenant occupied buildings differently. All owner-occupied buildings over 1,000 SF must begin disclosing benchmarking results in January 2011. Multi-tenant buildings over 50,000 SF must begin disclosing benchmarking results in January 2011 with the SF threshold dropping to 1,000 SF by July 2012. Washington State enacted a bill in 2009 that closely resembles the California law.
In New York City, a similar program is taking shape, affecting as many as 22,000 buildings. You’ll notice that these programs use 50,000 square feet as a minimum threshold for the benchmarking requirement, exempting smaller buildings. However, it is also worth noting that nationwide, about half of the commercial building stock consists of buildings under 50,000 square feet, so this threshold exempts about half the buildings in the market. The Washington, DC policy looks similar, which is not surprising in that these jurisdictions were generally aware of the others’ initiatives, and sought to both borrow successful formulas and to establish consistent requirements across different markets. This can help major real estate owners and operators manage their portfolios consistently in these major metro area markets.
Voluntary initiatives are proliferating to provide energy performance information to help public and private building owners measure, and better manage, their energy consumption. In some cases, incentives are linked to the benchmarking system, as in New Mexico where tax credits are available. In New Jersey, the Pay for Performance program offers cash incentives for measured savings using benchmarking tools. We’ll look a little deeper into some of these examples on the following slides.
In the LEED Existing Buildings program, almost 500 buildings have achieved recognition under the program, and over 2000 more are registered but not yet received certification. As this program continues to grow, utilities will see an increase in requests for energy data to complete the application process.
The federal government, which is the nation’s largest energy customer when all agencies including Defense facilities are included, is beginning to use the Portfolio Manager system as a performance tracking tool. Executive Order 13423, signed in 2007, gave rise to a collaborative effort between EPA, DOE, and GSA to create a checklist for Federal High Performance Sustainable Green Buildings. This checklist, while not binding, requires Portfolio Manager as the software system for tracking and reporting energy performance.
The American Recovery and Reinvestment Act, also known as “the stimulus bill”, included billions of dollars for energy efficiency and related clean energy investments. Two programs—the State Energy Program and the Energy Efficiency and Conservation Block Grant program, each are channeling about $3 billion to state and local government grantees. The largest single use of these funds is to improve existing state and local government buildings. As this slide shows, many of these grantees are using Portfolio Manager as a tracking and reporting tool, from Maine to Utah. The reporting will continue through most of 2012.
ComEd developed their Energy Usage Data System to respond to requests for whole building energy usage data for Portfolio Manager benchmarking. Since the launch of the tool in June of 2008, ComEd has provided whole building energy data for over 1,250 building for Portfolio Manager benchmarking. - Over 300 Building Managers Using Tool - Over 8,800 months of data requests from June 2008 to May of 2010
Drilling deeper still, this slide begins a more detailed look at one utility—PG&E in the San Francisco Bay area. PG&E has gone further with ABS than almost any other company, and thus merits a closer look. Through 2009 PG&E had provided ABS to almost 2400 buildings, and in that year engaged more than twice the number of buildings it worked with in 2007. And the program continues to grow.
There are a variety of options for getting data into Portfolio Manager. The tool supports online data entry for one building at a time. There are also Excel templates available for the bulk import of data. The focus of the rest of the presentation is the most advanced option – automated benchmarking. This approach automates the import of data into Portfolio Manager and significantly reduces the amount of manual data management
So what is ABS, exactly? The Automated Benchmarking System was developed by EPA to create a framework for exchanging energy data between the Portfolio Manager system and other parties over the Internet. ABS uses Web services and Extensible Markup Language (XML) to receive data authorizations from Portfolio Manager, transfer energy data and/or building data, and report benchmarking results. Utilities use ABS to set up a benchmarking service for their customers to assist customers with getting the twelve months of energy data required for benchmarking in Portfolio Manager. Utilities can set up a system that leverages ABS to receive customer requests for benchmarking from Portfolio Manager and send twelve months of energy data and ongoing monthly updates to facilitate benchmarking. ABS allows use of the Internet for fast, low-cost, flexible arrangements to get data where customers need it to go.
