Enabling Efficient, Responsive, and Resilient Buildings: Collaboration Between the United States and India

The United States and India have among the largest economies in the world, and they continue to work together to address current and future challenges in reliable electricity supply. The acceleration to efficient, grid-responsive, resilient buildings represents a key energy security objective for federal and state agencies in both countries. The weaknesses in the Indian grid system were manifest in 2012, in the country’s worst blackout, which jeopardized the lives of half of India’s 1.2 billion people. While both countries are investing significantly in power sector reform, India, by virtue of its colossal growth rate in commercial energy intensity and commercial floor space, is better placed than the United States to integrate and test state-of-art Smart Grid technologies in its future grid-responsive commercial buildings. This paper presents a roadmap of technical collaboration between the research organizations, and public-private stakeholders in both countries to accelerate the building-to-grid integration through pilot studies in India.

BioenergyKDF: Enabling Spatiotemporal Data Synthesis and Research Collaboration

The Bioenergy Knowledge Discovery Framework (BioenergyKDF) is a scalable, web-based collaborative environment for scientists working on bioenergy related research in which the connections between data, literature, and models can be explored and more clearly understood. The fully-operational and deployed system, built on multiple open source libraries and architectures, stores contributions from the community of practice and makes them easy to find, but that is just its base functionality. The BioenergyKDF provides a national spatiotemporal decision support capability that enables data sharing, analysis, modeling, and visualization as well as fosters the development and management of the U.S. bioenergy infrastructure, which is an essential component of the national energy infrastructure. The BioenergyKDF is built on a flexible, customizable platform that can be extended to support the requirements of any user community especially those that work with spatiotemporal data. While there are several community data-sharing software platforms available, some developed and distributed by national governments, none of them have the full suite of capabilities available in BioenergyKDF. For example, this component-based platform and database independent architecture allows it to be quickly deployed to existing infrastructure and to connect to existing data repositories (spatial or otherwise). As new data, analysis, and features are added; the BioenergyKDF will help lead research and support decisions concerning bioenergy into the future, but will also enable the development and growth of additional communities of practice both inside and outside of the Department of Energy. These communities will be able to leverage the substantial investment the agency has made in the KDF platform to quickly stand up systems that are customized to their data and research needs.

Nuclear Forensics International Technical Working Group (ITWG): a collaboration of scientists, law enforcement officials, and regulators working to combat nuclear terrorism and proliferation

Founded in 1996 upon the initiative of the “Group of 8” governments (G8), the Nuclear Forensics International Technical Working Group (ITWG) is an ad hoc organization of official Nuclear Forensics practitioners (scientists, law enforcement, and regulators) that can be called upon to provide technical assistance to the global community in the event of a seizure of nuclear or radiological materials. The ITWG is supported by and is affiliated with nearly 40 countries and international partner organizations including the International Atomic Energy Agency (IAEA), EURATOM, INTERPOL, EUROPOL, and the United Nations Interregional Crime and Justice Research Institute (UNICRI) (Figure 1). Besides providing a network of nuclear forensics laboratories that are able to assist the global community during a nuclear smuggling event, the ITWG is also committed to the advancement of the science of nuclear forensic analysis, largely through participation in periodic table top and Collaborative Materials Exercises (CMXs). Exercise scenarios use “real world” samples with realistic forensics investigation time constraints and reporting requirements. These exercises are designed to promote best practices in the field and test, evaluate, and improve new technical capabilities, methods and techniques in order to advance the science of nuclear forensics. Past efforts to advance nuclear forensic science have also included scenarios that asked laboratories to adapt conventional forensics methods (e.g. DNA, fingerprints, tool marks, and document comparisons) for collecting and preserving evidence comingled with radioactive materials.

Status of Dual-readout R&D for a Linear Collider in T1015 Collaboration

The hadronic energy resolution required for an hadronic operating at lepton collider is at the limits or even exceeds that obtained with traditional techniques. Furthermore, it is a well established fact that the presence of an electromagnetic section in front of an hadron calorimeter, as occurs in the layouts of the majority of detectors operating at a collider, would deteriorate the hadronic energy resolution of the device. The novel $ADRIANO$ technology (\textit{A Dual-readout Integrally Active Non-segmented Option}), currently under development at Fermilab, overcomes the above limitations by complementing an integrally active calorimeter with the dual-readout technique. Detailed Monte Carlo studies indicate that the energy resolution is in the $25\%/\sqrt{E}$ - $38\%/\sqrt{E}$ interval with a linear response of the detector up to an energy of 200 GeV. A baseline configuration is chosen with an estimated energy resolution of $\sigma(E)/E\approx30\%/\sqrt{E}$. Several prototypes have been built by \textit{T1015} Collaboration at Fermilab, to explore the effect of modifications of the layout from the baseline configuration. Preliminary results from several test beams at the \textit{Fermilab Test Beam Facility} (FTBF) of $\sim1\lambda_{I}$ prototypes are presented. Future prospects with ultra-heavy glass are, also, summarized.

Easy and Enticing: How a Collaborative Approach to Emerging Technology Adoption in the Commercial Building Sector Has Made Its Mark

In 2012, the U.S. Department of Energy (DOE), in collaboration with interested partners (e.g., applicable trade groups), initiated a novel market transformation approach, technology adoption campaigns, to speed the adoption of new technologies that save energy and money in buildings—first with lighting and later with other building technologies. This approach couples technical performance evaluation, guidance, data tracking and technical assistance with recognition for exemplary performance and best practices. Campaigns can be designed around emerging technologies that have significant, cost-effective national energy savings potential and where there is strong public- and private-sector interest in sharing performance criteria and outcomes. Participants in the campaigns share project data with the national laboratories and DOE, benefit from technical support and assistance from objective experts, and highly value recognition for their accomplishments. DOE and its campaign partners benefit from accelerated adoption of new energy-saving technologies and engagement with manufacturers and end users that allows for data collection and insights into technology research needs. This paper documents the success, challenges, lessons learned, and energy and cost savings of lighting campaigns, and in many cases compares these findings with other campaign efforts. This paper also presents recommendations for how other programs of various sizes can employ this model.

Twenty Years of Collaborative Materials Exercises by the Nuclear Forensics International Technical Working Group

The Collaborative Materials Exercise (CMX) series are a critical mechanism used to advance the ITWG's mission of identifying, developing and promoting the best practices of nuclear forensics. These exercises are not designed to test laboratory performance, but as learning experiences that provide opportunities for participants to test and demonstrate state-of-the-practice to the global scientific and law enforcement communities. They are run as mock nuclear forensic investigations under realistic scenarios, with timelines and conditions designed to mimic actual operations. These situations provide the relatively unique opportunity for the appropriate governmental agencies to exercise their collective response to a nuclear security incident. Utilizing well-characterized materials of a known history and origin that are taken from specific process locations within the nuclear fuel cycle, these 'real world' materials are used to fully consider the potential significance of process-derived heterogeneities and characteristics that might be used by investigators to derive useful information such as intended use, point of loss of control, process history or origin. While individual laboratory results are kept confidential, a summary of the major outcomes of each exercise is published in the open literature. The ITWG has carried out six CMXs since 1999. The sixth (CMX-6) and largest (21 participants) was completed in June 2019. Each CMX has contributed demonstrably to advancements in the state of practice and the emergence of novel techniques in nuclear forensic science.
