EL Releases Next Generation Coupled Building Energy and Airflow Simulation Tool
High performance buildings must meet demanding energy and IAQ requirements through the use innovative building designs and technologies for ventilation and IAQ control, such as natural ventilation and demand controlled ventilation. The design and analysis of these buildings and systems requires advanced building modeling capabilities. NIST is undertaking a project to develop new engineering tools that integrate multizone airflow and IAQ modeling, building thermal simulation, and CFD analysis, which will also be used to support energy, ventilation and IAQ standards and green building programs.
NIST and TESS, Inc. previously collaborated to create a combined multizone thermal and airflow building simulation by coupling limited aspects of the airflow portion of the NIST CONTAM model with the TRNSYS energy simulation program. CONTAM is a multizone airflow and contaminant dispersal program with a graphical interface for data input and display. TRNSYS is a transient system simulation program with a modular structure that was designed to solve complex energy system problems by breaking the problem down into a series of smaller components.
While the initial coupled TRNSYS/CONTAM tool has been used successfully, it did not include a full integration of the capabilities of the two tools. The recently released, second generation coupled simulation tool greatly expands the functionality by adding multizone contaminant simulation and access to all of CONTAM’s airflow modeling components, including the ability to simulate air handling systems and ducted airflow networks.
The new simulation capability is enabled in the latest version 3.1 of CONTAM, which is available for download from NIST at http://www.bfrl.nist.gov/IAQanalysis/software/ .

EL Drives International Standard for System Operation Requirements to Adoption
OMG has been an international, open membership, not-for-profit computer industry consortium since 1989. The OMG Task Forces develop enterprise integration standards for a wide range of technologies, including: Real-time, Embedded and Specialized Systems, Analysis & Design, Architecture-Driven Modernization and Middleware and an even wider range of industries, including: Business Modeling and Integration, C4I, Finance, Government, Healthcare, Legal Compliance, Life Sciences Research, Manufacturing Technology, Robotics, Software-Based Communications and Space. OMG’s modeling standards, including the Unified Modeling Language™ (UML®) and Model Driven Architecture® (MDA®), enable visual design, execution, and maintenance of software and other processes, including IT Systems Modeling and Business Process Management. OMG’s middleware standards and profiles are based on the Common Object Request Broker Architecture (CORBA®) and support a wide variety of industries.

Engineering Laboratory Leadership Culminates in International Standard for Core Manufacturing Simulation Data
Leadership for the standardization effort were provided by the Engineering Laboratory members Swee Leong (Chair), Frank Riddick (Vice Chair), and Tina Lee (Secretary). Their efforts included proposing the standard concept, leading the standardization development group, collaborating with industry partners for standard validation testing, and performing the balloting process. Riddick and Lee also served as Co-Editors of the SISO-STD-008-01-2012 and SISO-STD-08-2010 standards’ documents.

NIST Workshop on Dexterous Manipulation for Manufacturing Applications
The ability of humans to manipulate a wide range of objects with great dexterity and precision enables them to operate productively in the world. People can build things, take them apart, and determine many part properties simply by touch. This is currently beyond the capabilities of even the most sophisticated robots, and is a major obstacle to implementing robots in small and medium-size enterprises. This obstacle also places limitations on large manufacturers interested in using robotics for small-batch production. Typically, manufacturers cannot justify the cost associated with conventional practices, such as fixed tooling and purpose-built manipulation systems, for smaller production runs.
The workshop consisted of three technical sessions each followed by industry panel discussions to address desired application scenarios that require more dexterous manipulation, high priority advances needed to enable industry’s use of more dexterous robots, and performance metrics to support the advancement of dexterous robots. Workshop results and recommendations will be documented in a report to be released in March.

Impact of NIST Research and Services
New England Robotics Center Replicates NIST-DHS-ASTM Standard Test Methods
EL researcher Ann Virts worked with NERVE Center Director Holly Yanco and NERVE Center Manager Adam Norton for the past several months to finalize the design of the center. In January, Ann spent four days at the NERVE Center to help UMass students and staff to fabricate and calibrate the ASTM test method artifacts. Standard test methods were fabricated for a variety of terrains, obstacles, and tasks for evaluating robot system performance, including ramps, stairs, sand, and underbody inspection. In addition, Ann taught the UMass test administrators the proper methods to conduct the tests, measure data, and record results. The grand opening of the NERVE Center was February 12, 2013. More information, including photographs, can be found at the center web site, http://nerve.uml.edu/.
