This website provides a portal to Lawrence Berkeley National Laboratory (LBNL) research and development in energy benchmarking for homes, commercial buildings and industrial applications. Benchmarking is useful for property owners, facilities operators, and designers. It facilitates energy accounting, comparing a facility's energy use to similar facilities in order to assess opportunities for improvement, and quantifying/verifying energy savings. LBNL's work includes research on benchmarking techniques, services, and databases as well as the development and evaluation of specific benchmarking tools.

METHODS, DATABASES, & SERVICES FOR TOOL DEVELOPERS
- > LBNL Action-Oriented Benchmarking System: A web service consisting of a set of non-residential benchmarking and visualization methods that draw upon a database containing sets buildings that can be combined in various ways to obtain "peer groups" against which individual buildings can be compared. The AOB System is used to author a new generation of "action-oriented" tools in which the benchmarking process leads directly to guidance and recommendations on how to improve energy efficiency. The first such tool is EnergyIQ (described below) [more info: Evan Mills and Paul Mathew]

SPECIALIZED FACILITY & PROCESS TOOLS
- > BEST: Benchmarking and Energy Savings Tool for Industries
- Excel-based spreadsheet tools for use by industries to benchmark a plant's energy intensity to "best practice" and to identify energy-efficiency options that can be implemented. Data on annual energy use by fuel and characteristics of major production process at the facility is used by the spreadsheet tool to compare the plant to global best practice. "Best practice" is defined as the plant with the most energy-, and, for certain industries, water-efficient, commercially-available technologies for each step of the manufacturing process, taking into account the variables entered by the user (such as product and feedstock mix or location of the plant).

RELATED PROCESSES & TOOLS
- > Cost-Effectiveness of Commercial-buildings Commissioning and Retrocommissioning: Ongoing database and meta-analysis of commercial buildings (retro)commissioning efforts. Current database contains results for 224 buildings in 22 states. [more info: Evan Mills]
- > Monitoring-based Commissioning: The project uses predictive benchmarking to prioritize candidate commissioning projects within and across multiple campuses. The University of California (UC), California State University (CSU), and California Investor-Owned Energy Utilities are collaborating in an innovative new program to retro-commission campus facilities with the assistance of permanently installed energy monitoring equipment and trending capability. This monitoring-based commissioning (MBCx) effort spans twenty-five campuses, with nine projects for plant systems and 37 projects for buildings. Half of the buildings include laboratory or other energy-intensive space. [more info: Karl Brown]
- > Continuous Performance-Monitoring Systems for Commercial Buildings: A research and development project on performance monitoring in large commercial buildings. The goal of this project was to promote continuous performance monitoring systems in large commercial buildings in order to provide building operators with ready access to improved information to operate buildings more efficiently and reduce other operating costs.
