    ORNL-Developed Building Efficiency Software Now Available

    • Credit: ORNL

      Automated calibration software for building efficiency studies, developed by Oak Ridge National Laboratory researchers Jibonananda Sanyal (left) and Joshua New, is now available as an open source code.

    OAK RIDGE, Tenn, Sept. 2, 2015 -- A set of automated calibration techniques for tuning residential and commercial building energy efficiency software models to match measured data is now available as an open source code. The Autotune code, developed at the Department of Energy's Oak Ridge National Laboratory, is available on GitHub.

    ORNL principal investigator Joshua New, in collaboration with a team of researchers, developed the automated calibration software, which reduces the amount of time and expertise needed to optimize building parameters for cost and energy savings.

    By cheaply producing calibrated building energy models, Autotune allows “no-touch” audits, optimal retrofits and other simulation-informed applications to be cost-effectively realized for buildings traditionally too small (below 50,000 ft2) to be serviced by industry.

    “The methodology uses multi-parameter optimization techniques, in combination with big data mining-informed artificial intelligence agents, to automatically modify software inputs so simulation output matches measured data,” New, a researcher in ORNL's Building Technologies Research and Integration Center, said.

    “Instead of having a human change the knobs, so to speak, the Autotune methodology does that for you,” BTRIC researcher Jibonananda Sanyal said.

    To develop their software, the team used DOE supercomputing and computational resources -- including ORNL’s Titan supercomputer and the National Institute for Computational Sciences’ Nautilus system -- to perform millions of EnergyPlus simulations for a range of standard building types with generated data totaling hundreds of terabytes. Titan resides in the ORNL Leadership Computing Facility, a DOE Office of Science User Facility.

    By mining this data and trying many different calibration algorithms, the researchers were able to identify techniques and evolutionary computations that can quickly evolve a building to match measured data. On Titan, the team has been able to run annual energy simulations for more than half a million buildings and write 45 terabytes of simulation output to disk in less than one hour using over a third of Titan’s nearly 300,000 CPU cores in parallel.

    The code made available contains: (1) a backend that performs the evolutionary calibration, (2) a web service that allows scripting for calibrating large numbers of buildings and (3) a front end website which allows users to interact with the software.

    Autotune is available via Github, https://github.com/ORNL-BTRIC/Autotune. For more information, contact Joshua New, (865) 241-8783, newjr@ornl.gov.

    The study was supported by DOE's Office of Energy Efficiency and Renewable Energy – Building Technologies Office, and the DOE Office of Science.

    UT-Battelle manages ORNL for the Department of Energy’s Office of Science. The Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time.

    Capturing the behavior of single-atom catalysts on the move

    Capturing the behavior of single-atom catalysts on the move

    Scientists are excited by the prospect of stripping catalysts down to single atoms. Attached by the millions to a supporting surface, they could offer the ultimate in speed and specificity. Now researchers have taken an important step toward understanding single-atom catalysts by deliberately tweaking how they're attached to the surfaces that support them - in this case the surfaces of nanoparticles.

    Watching Molecules Split in Real Time

    Watching Molecules Split in Real Time

    Using a new X-ray technique, a team of researchers was able to watch in real time as a molecule split apart into two new molecules. The method could be used to look at chemical reactions that other techniques can't catch, for instance in catalysis, photovoltaics, peptide and combustion research. The team, led by researchers from Brown University in collaboration with the Department of Energy's SLAC National Accelerator Laboratory, published their results in March in Angewandte Chemie.

    Catalyst Renders Nerve Agents Harmless

    A team of scientists including researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has studied a catalyst that decomposes nerve agents, eliminating their harmful and lethal effects. The research was published Friday, April 19, in the Journal of Physical Chemistry Letters. "Our work is part of an ongoing, multiagency effort to protect soldiers and civilians from chemical warfare agents (CWAs)," said Anatoly Frenkel, a physicist with a joint appointment at Brookhaven Lab and Stony Brook University and the lead author on the paper.
