DOE’S Energy Modeling Ecosystem
OpenStudio bridges the
gap between capable but
complex engines and the
easy-to-use applications
that drive energy savings.
• Open Source
• Cross Platform
• Collaborative
The Technology
Performance Exchange
(TPEx) and Building
Component Library (BCL)
provide the raw data that
powers the ecosystem.

Ways to Address
1. Lower administrative costs
– Automate tracking and approvals
– Streamline communications
– Streamline reporting to regulators
2. Make energy analysis cheaper
– Analyze faster = more savings per hr worked
– Consultants paid per kWh/kW/Dth saved
3. Find deeper savings
– Will soon require advanced technologies
– Technologies can’t be modeled in current tools

Xcel Energy’s Solution
1. EDAPT web service - Lower administrative costs
– Tracks project status and next steps
– Manages data and communications in one place
– Reports program-wide outcomes
2. OpenStudio & EnergyPlus - Make analysis cheaper
– Free, publicly available tools
– Quickly model many EEMs
– Automate QAQC
– Analysis results directly into EDAPT
– Automated report generation
3. OpenStudio & EnergyPlus - Find deeper savings
– Expanding library of EEMs to model advanced tech quickly
– DOE continues to support and add new technologies

OpenStudio - EDAPT Integration
• EDAPT leverages open source
tools and data sources
– EnergyPlus: DOE’s flagship building energy
simulation engine
– Radiance: DOE’s daylighting analysis engine
– OpenStudio: Enables rapid development of
tools for auditor and design practitioners
– Building Component Library: Extensible online
repository of modeling inputs and measures
Drag-and-drop EEMs from the Building
Component Library make design alternative
modeling rapid and repeatable
13. 13
OpenStudio – EDAPT Integration
• OpenStudio packages results
for upload
– Required simulation results for all
design alternatives
– Automated model quality checks
– Automated EDA protocol checks
28. 28
Energy Consultants (ECs):
• Automate ECMs, and reuse them across many projects
• Junior modelers can assess more ECMs, more quickly
EDA Program Managers:
• Automate common ECMs, and share with all ECs
• Automate QA/QC to catch common errors and protocol
violations

DOE’s Goal – National Impact
Working with:
Austin Energy
CPS (San Antonio)
Duke Energy
National Grid
Others
DOE is making
EDAPT available to all
utilities nationwide
