Energy Exchange: Federal Sustainability for the Next Decade
Why Energy Modeling?
• Standardized calculation methods• Assumptions documented• Captures interactions between ECMs• All parts of building (lights, HVAC, envelope, etc.)• All in one place
A custom calculator for your building!
Energy Exchange: Federal Sustainability for the Next Decade
Uses for an Energy Model
• Evaluate ECMs• Verify/challenge vendor claims• ESPC due diligence• Analysis for appropriated funds
• Standardized nature makes review easier• Compare against bills – find issues
Remember: it is a tool to help you!

Where to get an Energy Model
• If LEED, one should exist already• Investment grade energy audit• Make one! – many free software tools

DOE Energy Modeling Ecosystem
OpenStudio is an open source platform that bridges the gap between capable but complex engines and the easy-to-use applications that drive energy savings.
Simulation Engines
“Operating System”
Applications

Data for the Ecosystem
The Technology Performance Exchange (TPEx) and Building Component Library (BCL) provide the raw data that powers the ecosystem.
Utility Pilots
Manufacturer Data
Energy Exchange: Federal Sustainability for the Next Decade7
The Technology Performance Exchange
• Web-based repository of product-specific performance data• Engineering analysis → minimum parameters for robust analysis• Data provenance tracked: Who, How, and When• Automatically creates and stores OpenStudio components in the
Building Component Library
Energy Exchange: Federal Sustainability for the Next Decade
The Building Component Library
• An Internet-connected source of building energy modeling data:• Enables drag-and-drop modeling for quick technology evaluation• Provides consistent, detailed inputs to drive decision-making• Searchable readily available within applications• The BCL is key to OpenStudio’s extensibility
Energy Exchange: Federal Sustainability for the Next Decade
The BCL: A Source for Reusable Input Data
Components:•Assembled to form complete energy models
• Include constructions, lights, schedules, weather data, PV components, and more
Energy Exchange: Federal Sustainability for the Next Decade
The BCL: Fast and Reliable Measure Application
Measures:•Contain logic needed to
transform an energy model easily and consistently
•Can be applied singly or as part of a parametric analysis
Energy Exchange: Federal Sustainability for the Next Decade
Knowledge is passed one-to-one: Inconsistent, not scalable, not transparent
Watch closely.

Vision – Energy Model as FM Tool
• Design• Include efficiency in building requirements• Use model to “prove out” design• Lastly - submit for LEED
• Continuous Commissioning• Compare model to actual – find issues
• Compliance• Quickly evaluate ECMs ID’d during Audits
• Living asset• Update as building changes
