• The BPD statistically analyzes trends in the energy performance and physical & operational characteristics of real commercial and residential buildings.
The Buildings Performance Database
3
Design Principles
• The BPD contains actual data on existing buildings - not modeled data or anecdotal evidence.
• The BPD enables statistical analysis without revealing information about individual buildings.
• The BPD cleanses and validates data from many sources and translates it into a standard format.
• In addition to the BPD’s analysis tools, third parties will be able to create applications using the database. Inputs: The BPD • Large dataset of real buildings Outputs: Activities • Assess opportunities • Forecast project performance • Quantify performance risk Outcomes • More energy efficiency projects undertaken • More data on EE project performance
BPD unlocks the power of building energy
performance data.

BPD is seeking datasets that include:
• Required Fields
Basic Building Characteristics
City, State, Zip Code
Usage type (office, retail, home) Building floor area
Year completed
Electricity/fuel use for at least one year
• Optional Fields
Detailed Building Characteristics
Operational information (Portfolio Manager data),
such as:
Types of activities and associated floor area Operating hours
Number of occupants
Equipment & Asset information, such as:
Lighting type and controls
Air distribution configuration, controls, etc Heating and cooling equipment types &
efficiencies
Hot water equipment type & efficiency Wall, roof and window characteristics

BPD Data Privacy and Security
• The BPD has clear use restrictions, and stringent privacy and
security policies:
o Data can only be analyzed in aggregate through the BPD interface. The BPD analyses will never allow identification of specific buildings.
o All the records contained in the Database are anonymous. All personally identifiable information, such as name, street address, etc. of buildings or individuals are removed from the records prior to entry.
o Individual building records will not be released publicly. Any data that is properly marked as “proprietary data” is protected by law from release under the Freedom of Information Act.
o The Database’s security policies align with DOE policies and Information Security best-practices. The BPD employs Secure Sockets Layer (SSL) certificates with 2048-bit RSA encryption.
o DOE can provide a standard confidentiality statement to attach when providing your data for the BPD.

DOE’s Vision for Performance-Based Approaches
By making building energy performance clearly traceable:
• Owners, operators, and product and service providers can understand the
drivers of variations in building performance, identify efficiency investment opportunities, and project the likely savings from investments.
• Public sector actors can tailor the design and implementation of energy
efficiency programs and policies to be most effective given local market conditions and trends.

ENERGY STAR Portfolio Manager
Tracks building energy and water consumption, and provides a weather normalized EUI and a whole building score, based on actual energy performance.
16
Commercial Asset Score & Home Energy Score
Provides a whole-building score and identifies inefficient systems and potential capital upgrades, based on as-built physical characteristics (independent of operations).

To manage benchmarking programs, Cities combine data
about many buildings from a range of tools and sources
City A’s SEED
City B’s SEED Tax Assessor Database Tax Assessor Database Audit findings or Asset Score results
Enables cities to manage and analyze data in a private,
secure repository.

Standard Energy Efficiency Data (SEED) platform
• V1 designed to help cities manage data resulting from building performance reporting
programs for private and/or public buildings.
