Until now, planners have lacked suitable tools for assessing whether to replace windows when refurbishing buildings. The newly published BINE-Projektinfo brochure “Making well-informed decisions when refurbishing windows” (15/2013) presents the Uwin software program. Uwin determines possible savings when refurbishing windows and facades. The base data for the calculations is provided by a mobile measurement device that measures the thermal insulation value Ug for the glazing.
In just a few minutes, the Uglass device records the current heat transfer coefficient for the window glass. The process has been developed by scientists at ZAE Bayern and Stuttgart University of Applied Sciences. A measurement sensor with is fixed to the inner and outer panes with suction pumps. The sensor heats the glazing on the one side and measures the increase in temperature on the other side. The thermal insulation value is determined from the change in temperature across time. The measurement device can record U-values for all standard double-and triple-glazed systems. It is currently in the test phase.
The measured thermal insulation value is incorporated into the software calculations along with factors such as the materials, frame size and type of installation. Based on the results, the software assesses the window or the complete facade in terms of their energy efficiency. These values can be compared with those of the desired replacement window. Energy consultants and designers therefore now have a tool available to them that can be helpful both during day-to-day consulting and when making investment decisions.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
