A lack of rigorous design methods and comprehensive performance data has slowed U.S. acceptance of natural ventilation technology, which proponents argue can increase energy efficiency in commercial buildings as well as improve indoor environmental conditions. The National Institute of Standards and Technology’s (NIST) new LoopDA 1.0 software program (for Loop Design and Analysis) helps fill this critical information gap.
The LoopDA simulation tool enables building designers and engineers to determine the size of natural ventilation openings needed to provide desired airflow rates. Previously, building designers have had to make decisions using trial and error or based on past experiences. Although LoopDA 1.0 provides “first-cut” estimates rather than final results, it is a great improvement over the former “more art than science” approach, according to NIST developer Stuart Dols.
As described at a recent technical conference in the Netherlands* LoopDA allows users of the computer program to sketch rooms and vertical sections of a building, the location of natural ventilation openings (e.g., windows, doors and ducts) and the paths the air should take through the building (i.e., pressure loops). The program then enables designers to determine the size of the natural ventilation openings needed to control indoor air quality and thermal comfort using an engineering-based design process.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
