Energy Exchange: Federal Sustainability for the Next Decade2
Comply with federal regulations– EISA Sec. 432 (audits and reporting)– EO 13693 (remote audits)
Comply with state and local requirementsImprove energy performance of buildingsUnderstand energy performanceDocument energy systems
Why do Energy Audits?
Energy Exchange: Federal Sustainability for the Next Decade3
ASHRAE Definitions• Preliminary Energy Use Analysis• Level 1 – Walk Through Survey• Level 2 – Energy Survey and Analysis• Level 3 – Detailed Analysis of Capital-Intensive Modifications
Virtual or Remote Audits

Energy Exchange: Federal Sustainability for the Next Decade6
Expensive
Inconsistent collection, analysis, and reporting
Reports are not actionable
Efficiency measures are repetitive or inconsistent
Difficult to compare and prioritize measures
Future audits require new data collection efforts
Challenges with Energy Audits
Energy Exchange: Federal Sustainability for the Next Decade7
Avoid repetitive data entries
Easier data transfer
Improve analysis capabilities
Streamline the processes
What’s the Solution?
BuildingSync supports these solutions
Energy Exchange: Federal Sustainability for the Next Decade8
What is BuildingSync?
Structured data system for commercial building energy and water audit data implemented as an XML schema (JSON converter)
Building Energy Data Exchange Specification (BEDES) use case
Facilitates consistent data exchange between audit tools, analysis applications, and databases
Energy Exchange: Federal Sustainability for the Next Decade9
Structured data system
BuildingSync XML Schema
Energy Exchange: Federal Sustainability for the Next Decade10
• BEDES use case• Building Energy Asset Score• Standard Energy Efficiency Data (SEED) Platform • EISA 432 Compliance Tracking System• ASHRAE audit standard• Commercial audit software packages (in progress)

BuildingSync facilitates automated data transfer between applications
Energy Exchange: Federal Sustainability for the Next Decade
Value Proposition: Building Owners
Reduce Long-Term Audit Costs– Reuse previous audit data
Increase Audit Quality– Standard terminology definitions– Consistent units– Input constraints
Expand Usefulness of Data– Compare results across a portfolio– Import data to other BEDES-compliant platforms (Asset
Score, Building Performance Database, eProject Builder, SEED)
Energy Exchange: Federal Sustainability for the Next Decade13
Finalize and test with Asset Score, SEED, and CTS
Release version 2.0 in early September 2015
Coordinate with ASHRAE audit standard
Link with OpenStudio energy simulation platform
Work with energy audit software providers to implement BuildingSync
What’s Next?
Energy Exchange: Federal Sustainability for the Next Decade14
Work with software/audit providers to implement BuildingSync through discussions or formal procurement requirements for– CTS reporting– Store audit data in SEED or other database for later use– Easier use of Asset Score– Expand analysis options
