Urban green spaces not only have a relaxing effect in the short term, but also reduce the physical and mental stress of the urban population in the long term. A decisive factor for the future of healthy

Swissbau Lab opens up new horizons for the industry. From 6 May 2025, the program design for Swissbau 2026 will start, with a focus on innovation, cooperation and sustainable

The canton of Lucerne plans to increase the contribution of photovoltaics as an energy source. To this end, areas of road infrastructure are to be utilised as solar power plants. The photovoltaic potential is now being tested on the noise protection gallery in Knutwil and at the Rontal bridge near

Zurich Airport is starting the construction of a second test well in an ice age channel under the site. It is to be used as a heat and cold reservoir to cover the heating and cooling requirements of the airport building. A first test well has delivered positive

Researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) have found a way to reduce the energy loss of perovskite solar cells and increase their efficiency. The integration of rubidium using lattice voltage produces a more stable electronic

Researchers from the Swiss Federal Laboratories for Materials Science and Technology (Empa) are participating in the construction of a water wheel in Steffisburg. The aim of the water wheel is to continue to supply the Mühlebach stream with water and protect the ecosystem from drying

The Bergacker housing estate in Zurich-Affoltern will be completely renovated in the coming years. Swiss Life and the Habitat 8000 housing cooperative are focusing on a new replacement building that creates modern living space, preserves the character of the garden city and fulfils the highest

Hydrogen production by electrolysis is considered a key technology for the energy transition. However, its efficiency has so far been inadequate. Researchers at Northwestern University have now identified a previously overlooked energy loss and found concrete approaches to

Rain as a source of energy? What has long sounded like a dream of the future is becoming tangible. Researchers around the world are developing new processes to generate electricity from falling drops. Be it through a plug-like flow of water or through nanotechnology in solar systems. The energy

A research team from Empa and ETH Zurich is developing an innovative method for producing wood-based panels inspired by traditional shingle production. By using split wood and artificial intelligence, even low-grade hardwood becomes a sustainable building material with future

The Dutch infrastructure authority Rijkswaterstaat is using the Asphalt Recycling Train (ART) to recycle asphalt on site. The machine, which is currently in the test phase, removes worn asphalt, heats it, mixes it and rebuilds it on the

The Federal Office for Buildings and Logistics is planning an exploratory borehole for a geothermal site at the National Sports Center in Magglingen. The borehole is due to be drilled at the end of 2027. The aim is to gain insights into deep water resources for geothermal heat

A new study by Lucerne University of Applied Sciences and Arts shows that Minergie-certified buildings offer not only ecological but also economic added value. Investors and landlords benefit from higher initial rents, while tenants benefit from lower ancillary costs and greater living

Libattion has opened a new upcycling plant for batteries in Biberist. According to Libattion, this is the largest facility of its kind in Europe. The Opfikon-based company manufactures modular stationary energy storage systems from used batteries from electric

For the first time, the German Institute for Building Technology has issued a general type approval for load-bearing clay block masonry using the thin-bed method. The GIMA vertically perforated clay brick may therefore be used for load-bearing walls up to building class 4. In combination with the

The Basel-based electricity producer aventron has inaugurated a solar installation on the Lintharena in Näfels. It will generate 124 megawatt hours per year over an area of 660 square meters. Aventron aims to achieve a solar output of 100 megawatts by
