Research project promotes circular economy in the construction industry
A group of students at the Swiss Federal Institute of Technology in Zurich (ETH) is using digital technology to recycle building materials. For their research, they visit construction sites, dismantle buildings and analyse the existing materials to develop new construction processes for external

Choice of materials to combat the urban heat
The material catalog "Building materials for cities in a changing climate" is now available in an expanded new edition. It shows how the right choice of materials can specifically influence heat stress, urban climate and quality of stay in densely built-up areas and provides planners with a


Concrete as CO₂ storage
The "Mining the Atmosphere" research initiative shows that excess CO₂ from the atmosphere can be permanently stored in building materials such as concrete. With a storage capacity of up to ten billion tonnes of carbon per year, this approach could help to reduce CO₂ levels to a climate-friendly

Buildings as carbon sinks
The construction industry is on the brink of a revolution. In future, buildings could not only be CO2-neutral, but even CO2-negative. The Empa initiative "Mining the Atmosphere" is pursuing precisely this goal. The NEST unit "Beyond Zero" is testing innovative materials that can permanently bind

Future Perfect launches project for circular construction
The Future Perfect association, together with various professional associations and an educational publisher, is launching a project to integrate circular building into vocational training. The goal is to teach skills for the reuse and recycling of building

Green Building nimmt die graue Energie ins Visier: Eine branchenweite Analyse
In view of the increasing environmental impact of construction activities, the issue of grey energy - the energy that is hidden in the production and disposal of building materials - is increasingly becoming the focus of the construction and real estate industry. The industry faces the challenge of

New school toilets to transform Sri Lanka’s construction industry
With the construction of toilet facilities at a school in Sri Lanka, the Laboratory of Construction and Architecture at the Swiss Federal Institute of Technology Lausanne (EPFL) is demonstrating how the industrial restructuring of construction in the country can succeed. The prototype is based on

Recycling construction waste instead of landfilling it
The Department of Construction wants to orient the guidelines for handling construction waste even more strongly towards the circular economy. If as much construction waste as possible is reprocessed into building materials, this conserves natural resources as well as the scarce landfill capacities


Availability of wood has stabilized
Der Holzbau boomt. Aber, weil der Nachschub aus dem Ausland im letzten Jahr bei vielen Baumaterialien stockte, wurden wichtige Holzprodukte rar und die Preise stiegen. Inzwischen zeichnet sich eine nachhaltige Beruhigung ab: Die Verfügbarkeit und die Preise von Holz haben sich in den letzten
