Supports technology demonstration and deployment, e.g. HPS to LED lighting upgrade
DOE Commercial Buildings Integration

Supports tool development, e.g. the standardized BuildingSync data format for tracking energy audit data & streamlined reporting to CTS
BuildingSync
Energy Audit Building Database
Develops technical guidance e.g. purchasing specifications for advanced control retrofits to rooftop HVAC units

Project Goal
Converge on an industry-accepted national DOE definition for ZE that will support program and policy goals and encourage commercial new construction and major renovation projects to design, construct, and operate buildings that achieve a high level of energy efficiency.

Project Background
• Buildings identified as (Net) Zero Energy (Ready) are becoming more prevalent
• There is a growing number of local, regional, and other definitions
• This can lead to confusion and uncertainty in claims, which might hamper growth of ZEBs and rigor of voluntary and mandatory programs
• There is a federal role in initiating the development of a common, clear national definition

Why a commonly accepted Zero Energy Definition?
For the building industry
• Focus on delivering great buildings (not definitional issues)
• Facilitate consistency and market branding
• Increase industry confidence
For states
• Alleviate market confusion
• Provides clarity leading to consumer confidence
• Consistent basis for incentive programs
• Align programs
• Consistency across state boundaries

Zero Energy Building (ZEB) Definition
An energy-efficient building*, where on a source energy basis, the actual annual delivered energy is less than or equal to the on-site renewable exported energy.
*or campus, community, or portfolio

Measurement and Implementation Guidelines
• Site boundary
• End-uses included
• On site renewables included
• Source energy calculations
• Export of renewable energy

• Efficiency first: – “ZEBs use all cost-effective measures to reduce energy usage through
energy efficiency and include renewable energy systems that produce enough energy to meet remaining energy needs.”
• RECS – separately addressed buildings that base some part of their claim on RECS
• Vehicles – a building can export power to vehicles (may be helpful for economics of ZEB)

Using “Zero Energy Building” Term
• Only buildings that have demonstrated through actual annual measurements that the on-site renewable exported energy is greater than or equal to delivered energy.
• Buildings designed to be zero energy, but have not yet had a full year of operation are encouraged to identify their intent to be a Zero Energy Building.

Encourage Market Growth of ZEB:
• Develop design & operation guidance
• Highlight case studies
• Grow use of energy targets in design-build contracts
• Catalog successful business processes for delivering ZEB
• Develop a recognition program
