Overview
The California Energy Commission Disclosure Summary Sheet
					 accompanies and describes three disclosure documents generated by the EPA's
					 ENERGY STAR® measurement and verification tool, Portfolio Manager: the
					 Statement of Energy Performance, the Data Checklist, and the Facility Summary.
					 The disclosures, required by Public Resources Code, Section 25402.10, are
					 standardized documents designed to provide insight into the energy use of a
					 building, under the space utilization and operational characteristics of the
					 building during the past 12 months. The disclosures include metrics for overall
					 building energy use, as well as a detailed description of the conditions the
					 building owner inputs to Portfolio Manager to generate the metrics.
Overall Building Metrics
Two metrics are used to report overall building energy use,
					 the ENERGY STAR® Energy Performance Score and the Energy Use
					 Intensity.
The ENERGY STAR Energy Performance Score compares a
					 building to a statistically representative national sample of similar
					 buildings. A score of 75 indicates that the building's energy consumption is
					 less than the energy use consumption of 75 percent of similar buildings
					 nationwide. ENERGY STAR cannot score all buildings, and not all buildings in
					 California will receive a score. Energy Use Intensity is a unit of measurement
					 that describes a building's energy use. It represents the energy consumed by a
					 building relative to its size.
Statement of Energy Performance
The Statement of Energy Performance is a standard report
					 generated by Portfolio Manager that describes a building's energy performance
					 in a format that is both understandable and easy to use in business
					 transactions. The Statement includes the name and location of the building; the
					 age, size, and rating, if any, of the building; and summaries of energy use and
					 greenhouse gas emissions. The Statement has a space for a licensed architect or
					 engineer to certify the accuracy of the data used to benchmark. Energy
					 Commission regulations do not require this certification for
					 disclosures.
Data Checklist
The Data Checklist is a standard report generated by
					 Portfolio Manager that summarizes a property's physical and operating
					 characteristics. The Checklist allows review of the way the space is being used
					 (for example, open office), as well as the hours of occupancy. The Checklist
					 verifies that the rating, if any, shown in the Statement of Energy Performance
					 is applicable to the real-world operation of the building. The Checklist also
					 summarizes the conventional and renewable energy being used within the building
					 by fuel type. There is a space for a licensed professional to certify the data.
					 Energy Commission regulations do not require this certification for
					 disclosures.
Facility Summary
The Facility Summary summarizes the data presented in the
					 Statement of Energy Performance and the Data Checklist. It also compares the
					 energy use of the building as it is currently operated against previous
					 performance (if available), along with the score required for the optional
					 ENERGY STAR label, and the average national energy use for a building with
					 similar characteristics. There is also a brief section devoted to cost and
					 greenhouse gas emissions associated with these energy uses.
Unscored Buildings
Many conditions may cause a building to not receive a
					 score. This does not mean that the building has better or worse energy
					 efficiency than comparable buildings.
Evaluating Unscored Buildings
Evaluating the Energy Use Intensity metric for an unscored
					 building against the median for the building's space type is another way to
					 gauge relative energy use. The following table gives median Energy Use
					 Intensity values for space types in California. Energy Use Intensity is
					 expressed in units of thousands of source British thermal units (BTUs) per
					 square foot that are consumed in a year. A detailed discussion of source and
					 site energy use can be found on the Portfolio Manager website.
The table below compares energy use of an unscored building
					 to the median energy use of a California building for that set of space types.
					 The table does not account for variations affecting building energy use such as
					 occupancy, worker density, computer equipment, or climate. The space types
					 significantly impacted by climate are indicated with an asterisk below.

Other Rating Systems and Standards
National and regional organizations provide checklists and
					 standards for energy use disclosure that provide a high level of detailed
					 information on building operations. Examples include, but are not limited to,
					 the ASTM Standard E2797-11, American Society of Heating, Refrigerating and Air
					 Conditioning Engineers (ASHRAE) Standard 100, ASHRAE Building Energy Quotient
					 (beQ), and the California Commissioning Collaborative (CCC) Existing Building
					 Commissioning Toolkit.
