Safeguards Technology Development Program 3rd Quarter FY 2018 Report June 30, 2018 GPS-Free Navigation in Buildings

This is an evaluation of candidate navigation solutions for GPS free inspection tools that can be used in tours of large building interiors. In principle, COTS portable inertial motion unit (IMU) sensors with satisfactory accuracy, SWAP (size, weight, power), low error, and bias drift can provide sufficiently accurate dead reckoning navigation in a large building in the absence of GPS. To explore this assumption, the capabilities of representative IMU navigation sensors to meet these requirements will be evaluated and field tested, starting with a market survey. To test the candidate COTS IMUs drawn from the market survey, we will design and fabricate a person-portable backpack for testing. We will provide a mobile power supply and data collection port. Then, we will test the IMUs on interior building tours at LLNL, finally carrying out an analysis of these sensors’ performance using LLNL’s navigation codes.

Achieving Regional Energy Efficiency Potential in the Midwest

The Midwest Energy Efficiency Alliance report on actions to accelerate adoption of energy efficiency in the Midwest through regional collaborations with state and local governments, utilities, industry, environmental and consumer groups and other stakeholders in a 13 state region (IA, IL, IN, KS, KY, MI, MN, MO, NE, ND, OH, SD and WI). MEEA collaborated with multiple Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EE) programs, including the Buildings Technologies Program (BTP), Office of Strategic Programs (OSP), Weatherization and Intergovernmental Programs (WIP), and Advanced Manufacturing Office (AMO) to further energy efficiency efforts in the Midwest. In addition, MEEA collaborated with other Regional Energy Efficiency Organizations (REEOs) such as the Northwest, Northeast, Southwest and Southeast REEOs. Such alignment among all REEOs and with DOE sought to build increased workforce capacities nationwide to design, plan, deliver and verify energy efficiency solutions and make individual REEOs more successful in reaching their objectives. The proposed work accelerated deployment of DOE initiatives in local and regional markets, as well as coordinated the activities of each REEO for the dissemination of best practices.

Materials 2018 Annual Progress Report

The Materials Technology Program supports the Vehicles Technologies Office’s mission to help consumers and businesses reduce their transportation energy costs while meeting or exceeding vehicle performance expectations. The propulsion materials research portfolio seeks to develop higher performance materials that can withstand increasingly extreme environments and address the future properties needs of a variety of high-efficiency powertrain types, sizes, fueling concepts, and combustion modes. Advanced lightweight materials enable improvements in fuel economy by providing properties that are equal to or better than traditional materials at a lower weight. Because it takes less energy to accelerate a lighter object, replacing cast-iron and traditional steel components with lightweight materials such as high-strength steel, magnesium (Mg), aluminum (Al), and polymer composites can directly reduce a vehicle’s fuel consumption. Materials technology activities focus on the following cost and performance targets: (1) enable a 25% weight reduction for light-duty (LD) vehicles including body, chassis, and interior as compared to a model year 2012 baseline at no more than a $\$$5/lb-saved increase in cost; and (2) validate a 25% improvement in high-temperature (300°C) development of engine exhaust catalyst materials strength relative to components made with 2010 baseline cast Al alloys (A319 or A356) for improved efficiency LD engines.

Molecular characterization of Mycoplasma capricolum subsp. capripneumoniae Pakistan strain for the establishment of effective diagnostics and vaccines. Pakistan-U.S. Science and Technology Cooperation Program Annual Technical Report

The primary goal of this project is to gather and analyze data supporting development of diagnostic tests and vaccines to mitigate contagious caprine pleuropneumonia in Pakistan. This disease of primarily goats and sheep is a substantial burden to agricultural productivity and survival of farmers and families in Pakistan. During this phase of the project, we have collected and analyzed (genome sequencing) clinical samples from a broad affected region in Pakistan. Preliminary results show that there are at least two distinct clades (variants) of the organism prevalent in different regions of the country. This information, combined with our planned efforts in the coming year, will help identify better methods to diagnose and vaccinate herds against this pathogen. Our vision is that this work will improve critical livestock health in Pakistan, and consequently economic and social stability.

2018 Technology Innovation Program Heartbeat

Heartbeat responds to this problem by focusing instead on the physical behavior of the device being protected, under the hypothesis that malware infection will produce a measurable change in the power consumption state of a device that can be picked up by an outside detector. All code execution uses power, so the execution of malware—especially polymorphic variants—will leave a trace on a power consumption record. The Heartbeat system collects power trace measurements directly from the hardware and so is invisible to malware and resilient to internet service interruption. By collecting power measurement data only during the periodic invocation of a single or of several system functions, Heartbeat will address several challenges that plague current anomaly-based intrusion detection systems and is operational-context agnostic.

Pathway to Zero Energy Windows: Advancing Technologies and Market Adoption

As of 2021, buildings account for 39.1% of total U.S. primary energy use and 75% of total U.S. electricity use. Much of this energy is used to maintain a comfortable indoor environment. The building envelope consists of transparent and opaque elements that serve as a controllable barrier to help maintain the indoor environment regardless of external conditions. The envelope also allows the exchange of light and air, as well as other transfers with the external environment when it is beneficial for the building occupants. By leveraging desirable external environmental conditions (e.g., fresh air and natural light) and mitigating the influence of undesirable conditions (e.g., moisture, hot or cold temperatures, wind), the building envelope can reduce the need for space conditioning and electric light, and thus reduce energy use associated with lighting and heating, cooling, and ventilation equipment. In turn, high-performance building envelopes can reduce the substantial CO 2 emissions associated with energy use to satisfy heating, cooling, and lighting needs in buildings. The U.S. Department of Energy (DOE) Building Technologies Office's (BTO's) Emerging Technologies program supports R&D for technologies, systems, and software tools that can contribute to reductions in building energy use. Emerging Technologies funding is distributed competitively through solicitations (e.g., Funding Opportunity Announcements and National Lab Calls, which in general are open to applications from industry, academia, national laboratories, and other entities) and other mechanisms. This document focuses on R&D for windows and window system technologies and will provide guidance for BTO's investments in developing the next generation of high-performance, affordable, cost competitive windows, as well as integrated daylighting and shading technologies in partnership with industry and researchers. This document also addresses areas where DOE invests in software and design tools that translate sophisticated and complex physics into easy-to-use energy performance and optimization methods used by industry and other stakeholders for implementation.
