Why Building Energy Labeling?Why Building Energy Labeling?

As the nation looks to reduce its energy use, information is

the critical first step in making the necessary choices and

changes

Information for Consumers to Allow Educated Choices is Not New

Building Energy Labels. . .

Promote the value of energy efficiency in the marketplace

Differentiate buildings with good performance for potential tenants/buyers

Enhance building owner’s ability to identify energy efficiency measures to help improve operations

Current “Building Label” Efforts in the US:

– Energy Star– DOE– LEED Certifications– Green Globes– BOMA 360

All of these Programs are Voluntary

Mandatory labeling requirements:

Now is the time to introduce a label that could serve as a consistent model for all

mandatory programs in the U.S.

Why Should Professionals & Owners Care?

• Professionals– An additional service for consulting firms and others– Required certifications demonstrate competency

• Owners– Benchmarking– Recognition for participation can enhance a

company’s image and reputation– Economic benefit of improving design and operation– Potential for mandatory labeling and related

requirements in future

Types of Ratings

In Operation Rating (Operational)

• Actual measured energy use of a building

• Based on combination of structure and features of the building and how it is operated

• Applicable for existing buildings • Applicable for new buildings after 12-18

months of operation

How Does The Rating Scale Work?

Technical potential scales can rate performance that falls outside the current distribution, like net zero or net positive buildings
