Commercial and residential buildings consume vast amounts of energy, water, and material resources. In fact, U.S. buildings account for more than 40 percent of total U.S. energy consumption, including 72 percent of electricity use. If current trends continue, buildings worldwide will be the largest consumer of global energy by 2025. By 2050, buildings are likely to use as much energy as the transportation and industrial sectors combined.
Submetering is the use of metering devices to measure actual energy or water consumption at points downstream from the primary utility meter on a campus or building. Submetering allows building owners to monitor energy or water usage for individual tenants, departments, pieces of equipment or other loads to account for their specific usage. Submetering technologies enable building owners to optimize design and retrofit strategies to energy and water management procedures more efficient and effective.
While the return on investment (ROI) for submeters depends on specific energy-efficiency strategies that may vary by climate, building type, and other factors, "numerous case studies provide evidence that the ROI can be significant," concludes the report,Submetering of Building Energy and Water Usage: Analysis and Recommendations of the Subcommittee on Buildings Technology Research and Development. Installing submetering technology also makes possible the use of more advanced conservation technologies in the future, the report notes.
The report is a product of the Buildings Technology Research and Development Subcommittee of the National Science and Technology Council (NSTC), a cabinet-level council that is the principal means within the executive branch to coordinate science and technology policy across the diverse entities that make up the federal research and development enterprise.
The NSTC report provides an overview of the key elements of submetering and associated energy management systems to foster understanding of associated benefits and complexities. It documents the current state of submetering and provides relevant case studies and preliminary findings relating to submetering system costs and ROI. The report also addresses gaps, challenges and barriers to widespread acceptance along with descriptive candidate areas where additional development or progress is required. It also surveys policy options for changing current buildings-sector practices.The 74-page report can be downloaded from: www.bfrl.nist.gov/buildingtechnology/documents/

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
