Detecting Energy Losses from the Air

Siemens has developed a new technology that can detect energy losses in large buildings and even entire city districts.

The technology uses an image processing system that works with aerial photographs taken by a camera drone. The system software uses the data from the cameras to create a three-dimensional model that visibly depicts thermal radiation, liquid and gas losses, areas with poor insulation, and spots with heavy moisture. The technology is already being used in the construction project for the new Aspern Urban Lakeside district in Vienna, Austria.

Searches for sources of geothermal losses (hotspots) were previously conducted on the ground, as were monitoring operations to measure progress at major construction sites. Stationary webcams or laser scanners were used here, but both have drawbacks because their viewing angle is often limited and the imaging devices can also get dirty from dust and rain. Recording equipment in a camera drone doesn't need to be cleaned and can also be used to create three-dimensional images.

The Aspern drone was built by Ascending Technologies. Depending on what it's used for, the drone can be equipped with either a conventional camera or a thermal imaging camera.

Aerial thermal inspections with the latter take less time and are also more reliable than inspections on the ground. Experts from Siemens Corporate Technology can collect all the required data during a flyover and then analyze it on a computer. This makes it possible to easily monitor objects that are normally difficult to access, and whose examination using conventional technologies would in some cases require inspectors to climb buildings.

The drone equipped with Siemens technology has been documenting the progress of construction in Aspern in test operations for a year. The new district in the eastern part of Vienna is itself a type of test lab for future urban design. The data the drone collects from above the giant construction site will help optimize planning operations in relation to logistics, energy consumption, and financing throughout the construction period. Use of the system is not limited to construction projects, as it can also assist with the efficient maintenance and servicing of finished buildings.

Im Focus: Climate study finds evidence of global shift in the 1980s

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.

Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

The Fraunhofer Institute for Solar Energy Systems ISE has installed 70 photovoltaic modules on the outer façade of one of its lab buildings. The modules were...

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...

Im Focus: Laser process simulation available as app for first time

In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.

Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
