Nearest Metro: Foggy Bottom (Orange, Blue, and Silver lines)


Presentation Topics include:

  1. The Shockingly Short Payback of Energy Modeling – Speaker Anica Landreneau, director of global sustainability consulting at HOK.

Presentation Description:  In case you missed the presentation at the Better Buildings Summit held at the US Department of Energy in May, Anica Landreneau of HOK will be giving an updated version of the presentation that led to the article “The Shockingly Short Payback of Energy Modeling” ( Modeling is critical to HOK’s mission and a key tool in maintaining the firm’s global standing as a high-performance leader. HOK sees modeling as a mechanism for shifting investment from a building’s active, mechanical systems to its passive, architectural elements, benefiting not only energy-efficiency, but also durability and aesthetics. Building energy modeling (BEM) is not a traditional ECM as it doesn’t directly save energy. However, by guiding selection and combination of direct ECMs, BEM is actually one of the most cost-effective ECMs. This presentation highlights the ROI of BEM, testimonials from project managers who use BEM to great effect and review options and resources for engaging with BEM early and often, and case studies of BEM application on local Washington DC projects.


  1. RAPMOD – Automated building of energy models for existing buildings – Speaker Annie Marston, head of building performance at Baumann Consulting.

Presentation Description:  RAPMOD in its current form has been in development over the last 3 years. However, the concept and technology have been worked on by University of California Berkeley for the last decade. RAPMOD is a wearable technology that allows the user while walking through a building to create a comprehensive 3D virtual environment of the building, as well as automatically creating an idf energy model including all geometry, windows, lighting levels, equipment levels and occupancy estimates. The technology allows the rapid creation of an energy model with minimal input (HVAC) from the modeler, freeing up time for analysis and experimentation.

 2.  Occupant Impact on Building Energy Consumption and Improvement of Building Energy Simulation with Occupant Information

Speaker: Yang-Seon Kim

Research from a dozen case studies in commercial buildings suggests that 10 – 40% of energy can be saved if the occupancy (presence/absence) is factored into the building operation. Occupant information is important to reduce the gap between actual building energy consumption and estimated energy consumption. This study quantified the impact of occupancy rates for actual commercial building energy consumption with measured data. Additionally, it found occupancy rates have a higher correlation with plug-load consumption than with total electricity consumption. This study shows a simplified methodology to use the plug-load consumption as an indicator for occupancy rates in building energy models.

Arup DC Projects – Nick Blanton ARUP

Nick Blanton will give a presentation about the design and simulation work completed for several local Arup projects. Specific modeling challenges will be discussed, as well as useful information for up-and-coming simulation consultants, based on experience gained from these projects.

Building Performance Benchmarking beyond Energy Star Portfolio Manager – Hyojin Kim Catholic University

Hyojin Kim will will introduce new protocols on building performance measurement and benchmarking developed by ASHRAE, CIBSE, and USGBC: Performance Measurement Protocols (PMP) for Commercial Building. As the first integrated protocols on energy, water, and indoor environmental quality, the PMP is expected to be used as a tool to verify green building practice and to identify building performance-related problems, which will help diminish the observed discrepancy between predicted and actual performance of buildings. An application of the PMP will be demonstrated using a case-study building.

OpenStudio Classroom Training

March 25-26

Washington, DC

Courtyard by Marriott Capitol Hill/Navy Yard


This 2-day hands-on course will teach building professionals, architects, and  engineers how to leverage the free NREL OpenStudio modeling ecosystem to quickly and efficiently generate flexible models for energy analysis. Students will learn effective modeling workflows for using the OpenStudio Sketchup Plugin to construct building form and fabric and assigning space attributes. HVAC and service hot water systems will be configured using the OpenStudio Application. The OpenStudio Application integrates with NREL’s Building Component Library (BCL), providing libraries of pre-defined configurable energy conservation measures for easily modifying energy models. PAT (Parametric Analysis Tool) will be used to demonstrate how model variants can be configured to run in cloud computing environments (Amazon EC2). Students will also be exposed to OpenStudio’s capabilities for extension through Ruby Scripting, both for creating custom energy conservation measures and for generating useful summary and detailed output.

Eligible for 12 AIA LUs.
