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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
