Rapid Energy Modeling Workflow Demonstration
Objectives of the Demonstration
To make consistent and well-informed decisions regarding energy reduction and sustainable facility management, the Department of Defense (DoD) needs a consistent, inexpensive, and easily deployable way to evaluate the existing energy consumption of individual facilities and to compare and identify which facilities are in greatest need of improvement. Current energy assessment methods, such as energy audits, are labor intensive and expensive, and energy database information cannot be guaranteed to be consistent and dependable across the Department.
The objective of this project is to validate the accuracy of Rapid Energy Modeling (REM), a protocol for rapidly calculating the energy consumption of an existing building. The project will also validate that satellite or aerial photography is a suitable substitute for the on-site photographic method used as part of producing a building model. If this is validated, the time required to capture the data needed to create a building model will be significantly reduced, allowing DoD to inexpensively perform REM on thousands of facilities each year.
This project will identify 32 DoD facilities of various types in different locations. These buildings will be surveyed and each building's energy manager will complete an energy questionnaire. Autodesk researchers will develop an energy model and analyze it with Autodesk Green Building Studio (GBS) software. GBS uses DOE-2.2 (eQuest) software to run the analyses. The results of these analyses are represented as annual energy use and cost, monthly energy use and energy demand, and energy use intensity (EUI) in kBtu/ft²/yr. The energy consumption predictions of GBS will be compared to historic utility bills. Less than a 10% variance between predicted and actual consumption is anticipated. If the variance is greater than this, researchers will revisit the site to determine why.
REM will provide a lightweight, easily deployable methodology for estimating energy consumption across the DoD enterprise and for identifying buildings that are the best choices for remediation. It will help DoD prioritize energy efficiency retrofit projects, track reductions in energy use, and manage facilities in new and cost-effective ways. The models can also be used to derive information about carbon footprint, identify the potential for integration of renewable energy technologies, and help achieve other sustainability management goals.
