From an energy perspective, windows have an opposite effect depending on the time of year: In winter, they allow solar heat into the interior and thus reduce heating demand. In summer, on the other hand, solar heat gain is often undesirable because it can lead to increased cooling demand. Blinds and other adjustable exterior solar shading systems serve to keep summer heat out of interior spaces. Weiterlesen

The extraction of gas molecules from a gas mixture and their adsorption onto a solid plays an important role in many industrial processes. In many cases, technical systems are used today for these adsorption processes that are oversized for their task. This consumes unnecessarily high amounts of adsorption materials, investment resources and energy. To avoid this, a team of researchers from the Lucerne University of Applied Sciences and Arts has developed a model and an associated guideline. They help process engineers to better design the appropriate dimensions of gas purification and gas recovery plants in proportion with requirements. The scientists estimate the potential energy savings at 25 to 30 percent.

People who fuel up with diesel or gasoline sometimes don’t even know that it contains biofuel. This is because small portions of biofuel do not have to be declared. Biogenic fuels account for almost 7% (diesel) and nearly 3% (gasoline) of the fuel sold in Switzerland. In the coming years, they could make a growing contribution to reducing greenhouse gas emissions in the mobility sector. This is thanks to their biogenic origin, but also to efficiency improvements in adapted engines. This is shown in a new study by a team of researchers from the Swiss Federal Institute of Technology Zurich (ETHZ) and the Swiss Federal Laboratories for Materials Testing and Research (Empa).

At first glance, one would hardly believe that a simple water tank could be enough to bring heat from summer into winter. But in fact, a storage tank with a volume of 12 cubic meters or more is enough to supply an apartment with heat and hot water from solar collectors for the entire winter. Because such storage solutions have been relatively expensive up to now, scientists from the universities in Rapperswil and Lucerne have been searching for ways to make the technology more economical in two research projects.

Geothermal energy is already used intensively in Switzerland, mainly by means of geothermal probes that collect heat from the ground to provide heat and hot water for buildings. However, the heat from deeper layers of the earth is hardly used: If one were to drill 1000 m and deeper, one would come across an enormous heat reservoir that can be used for heating purposes, industrial processes and electricity production.

Energy efficiency is at the core of the transition towards a more resilient and sustainable energy system. It takes innovative solutions to reduce industrial energy consumption to a level where the remaining demand can be supplied from renewable sources.

In response to this challenge, the SFOE research programme on Industrial Processes dedicates one million Swiss Francs to a competitive call for application-oriented research proposals in the area of industrial energy efficiency. Expecting that successful projects will deliver publicly assessable results with the potential to generate significant positive impacts. Weiterlesen

India provides unprecedented opportunities to scale solar and wind power, making it one of the forerunners of a world heading towards a sustainable future. However, there is one basic challenge that India must face: the intermittency of renewables. The article by Peter Freudenstein, an energy and climate change policy analyst and a Mercator Fellow, suggests methods that India can adopt to solve its problem. Weiterlesen
