ShutterstockAnyone planning to renovate the energy efficiency of their private property must consider many things, but can ultimately make a quick decision about implementation. The decision-making processes are much more difficult for condominium owners: If they want to renovate the parts of their property owned in common, they often have to appease a wide range of interests. A study conducted by the Lucerne University of Applied Sciences and Arts together with partners from the field looked at the financial side of such renovation projects and searched for innovative financing models.

Reducing energy consumption, through new ways of living and working, efficient mobility behavior or a changed environmental awareness – this is the goal of the SWEET call “Living&Working”. To this end, the two selected consortia SWICE and LANTERN are developing, implementing and testing new approaches, methods and technologies in so-called „Living Labs“. Joëlle Mastelic, professor at the University of Applied Sciences and Arts of Western Switzerland and coordinator of LANTERN, and Marilyne Andersen, professor at EPFL and coordinator of SWICE, tell us where the focus of their research lies and what is distinctive about research in Living Labs.

How much energy do buildings consume per canton, per municipality? How big is the heating demand? How much electricity did Switzerland consume yesterday? How many Smart Meters are installed per municipality? In terms of data freely available on the energy sector – so called Open Energy Data -, Switzerland has a lot of catching up to do compared to other countries. Why is that? What are the obstacles?

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.

The Swiss Environment and Energy Innovation Monitor carried out an online survey amongst 129 Swiss startups from the Energy and Environment sectors following a similar survey in 2020 focusing on COVID-19 effects, their work organisation, financing challenges and internationalization plans.
