When twelve of the biggest construction companies in Switzerland commit to the circular economy, it has an impact. Today, too many raw materials are still irretrievably lost in construction. If fewer non-renewable raw materials and energies are used, the construction industry will become much more

Repower, together with the municipality of Klosters and Klosters-Madrisa Bergbahnen AG, is planning to build an alpine solar plant at the Madrisa mountain railway. With an installed capacity of 12 MW, the plant in the "Züg" area could fully supply both the mountain railway and a large number of

87 percent of the Swiss want to further expand renewable energies such as wind, solar and hydropower. To achieve this, the majority (52 percent) are also prepared to dig deeper into their pockets. These are the results of the Energy Trend Monitor 2023, which was commissioned by STIEBEL ELTRON and

The increasing use of photovoltaic and wind energy in the future, which depends on the time of day and weather conditions, poses risks for the Swiss electricity grid. One solution is the use of hydrogen as an energy storage medium, which can be used for environmentally friendly electricity and heat

Building façades hold great potential for producing and saving energy. Today, however, this potential is still too little used. As part of the NEST HiLo unit, researchers from the Architecture and Building Systems Group at ETH Zurich have developed an innovative adaptive solar façade that

In autumn 2022, 33 students at the ZHAW in Winterthur experimented with the architectural potential of reusing building components - and achieved some surprising

Empa researchers want to develop a new type of insulating material from plant-based raw materials from waste, WHICH permanently binds the CO2 it contains by means of a special heat treatment - and thus acts as a CO2 sink. After the buildings have been deconstructed, this "plant carbon" together

Together with partners from politics, science and industry, ETH Zurich and EPFL want to advance solutions for the storage and transport of renewable energy sources. The goal: a climate-neutral and flexible energy system for Switzerland. Around 20 partners and industrial companies have already

In order to achieve the net zero target, the city of Zurich will connect around 60 per cent of the settlement area with district heating by 2040. At the same time, the city council wants to increase supply security and exploit synergies in the heat supply. It has therefore decided to reorganise the

It is to become easier to erect photovoltaic systems on condominium buildings. The National Council wants the Federal Council to amend the Condominium Ownership Act for this purpose.

The property sector is responsible for around a third of global greenhouse gas emissions and faces the urgent challenge of reducing them. Wincasa proactively supports its customers on the path to net zero. They are supported by the ESG data management platform developed jointly by Wincasa and the

Climate change also affects urban development: Asphalted city centres quickly overheat. The city of Winterthur is using a smart city project based on Lokstadt to show how this problem can be

The site of the ‘Pra Roman’ development in Lausanne has been awarded CHF 100,000 as an outstanding project for biodiversity in urban areas. Together with the developer, the Codha cooperative, the residents have created a green oasis for people and nature. Thanks to the early involvement of all

The Energy Commission of the Council of States proposes that the residual water provisions continue to apply without restriction. In return, it is in favour of areas where the use of solar and wind energy has priority over other interests. It rejects new obligations on solar installations on

With the new type of processing plant, the Recycling Centre Ostschweiz (RCO) is becoming even more innovative. The wet-mechanical plant makes it possible to recycle an even wider range of residues from the construction industry and thus return them to the material cycle. In this way, the RCO is

A research team involving the Paul Scherrer Institute (PSI) and the University of Grenoble Alpes is on the trail of a disadvantage of low-carbon cements: the slow hydration kinetics in the first three days. The aim is to achieve a faster strength of green

Global warming is one of the greatest challenges of our time. Swiss Heritage actively and fully supports the national energy strategy and is committed to the goal of a climate-neutral Switzerland by

The Swiss Association of Master Builders (SBC) is in favour of the adoption of the partial revision of the Environmental Protection Act, which will be dealt with by the National Council in the special session on 3 May 2023. The chosen regulatory approach consisting of a mixture of incentives,

If Switzerland wants to achieve its target of zero net greenhouse gas emissions by 2050, it will have to rely on the use of negative emission technologies (NET), i.e. processes that remove CO2 from the atmosphere and store it in the long term. Although NETs can in principle help to achieve the

Implenia is an industry leader in sustainability, as demonstrated by its new sustainability report, which complies with the requirements of the Global Reporting Initiative (GRI). All twelve of Implenia's ambitious sustainability targets for 2025 are well on

Glass blocks have long been popular in architecture to bring more light into buildings. Until now, however, they have not been suitable for load-bearing walls and have not insulated well. An Empa team has now developed a translucent glass block with good insulation properties thanks to aerogel,

The ideas of the circular economy pose new challenges for architecture: How can a stringent design be realised if as many building parts of a deconstruction as possible are reused for this purpose? Students of Bachelor Architecture at the Bern University of Applied Sciences are investigating this

The Ukraine war and its consequences have brought the dependence on fossil fuels home to us. An essential component of a future-oriented energy policy is sustainability in

If desired, the brand shower channel conceals an additional feature that can noticeably reduce the energy required for the shower. The channel in the one from Kaldewei has a heat exchanger that is completely integrated into the drainage channel, invisible to the user. This saves energy and produces

Flumroc AG is renewing its production plant. The centrepiece of the conversion is an electric melting furnace whose energy requirements are covered entirely by Swiss hydropower. This will reduce the company's CO2 emissions by 80 percent. The new plant is expected to be commissioned in summer

At its meeting on 17 March 2023, the Federal Council adopted amendments to the Energy Ordinance, the Energy Promotion Ordinance and the Electricity Supply Ordinance. These amendments will enter into force on 1 April 2023. They enable the implementation of the amendments to the Energy Act passed by

In an Innosuisse project, researchers from the Institute of Materials and Wood Technology IWH at the Bern University of Applied Sciences BFH are developing a new mineral binder for the production of wood-based materials. This should make them more sustainable.

The Global Real Estate Run mobilises tenants, owners and real estate professionals to get moving for a more generation-friendly real estate and construction

Transparency is an effective means of preventing greenwashing. The trend in the real estate sector is therefore towards the disclosure of important environmental indicators. REIDA, a non-profit association supported by the industry, supports this trend and has developed a standard for calculating

Sphärische Kugeln werden auf der Expo 2025 den Schweizer Pavillon «LA SUISSE ENCHANTÉE» bilden und ein Beispiel nachhaltiger Architektur darstellen. Mit viel Expo-Erfahrung und innovativen Ideen realisiert NÜSSLI mit Manuel Herz Architekten und BELLPRAT PARTNER den geplant leichtesten Pavillon
