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).

The Energy – Economy – Society (EES/EWG) research program promotes application-oriented research in the field of energy policy. To this end, the EES focuses on economic, social, psychological and political issues throughout the energy sector supply chain. EES elaborates calls to fund innovative socio-economic research projects that address relevant energy-policy questions for Switzerland. Weiterlesen

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.

Der erste SOUR (SWEET OUtside-the-Box Rethinking) Call endete am 31. März 2021. Das Format stiess auf hohe Resonanz, insgesamt wurden 77 Projektvorschläge eingereicht. Es waren Projekte gefragt, die ungewöhnliche und alternative Vorschläge bieten, um unser Energiesystem nachhaltig und klimaneutral zu gestalten. Der SOUR Call ergänzt den SWEET Call aus dem Jahr 2020. Dessen Leitthema ist die «Integration erneuerbarer Energien in ein nachhaltiges und resilientes Schweizer Energiesystem». Weiterlesen

Era il 23 febbraio 2016, quasi 5 anni fa, quando Martin Hertach annunciava su questo stesso blog l’attivazione della pagina web sonnendach.ch.

In maniera semplice e intuitiva (grazie alla collaborazione tra l’OFEN, swisstopo e meteosvizzera), veniva messo gratuitamente a disposizione della popolazione uno strumento in grado di dare indicazioni importanti sul potenziale solare di 4.2 milioni di tetti in Svizzera (circa il 50% del totale).

L’offerta si è ampliata sempre più e nel febbraio 2017 al potenziale dei tetti si è anche aggiunto quello delle facciate delle case, che può essere calcolato sul sito sonnenfassade.ch. Weiterlesen
