Bio-based and low-carbon materials

Besides energy transition, “materials transition” is the next relevant theme in our route to zero impact building. Where we can, we want to circulate materials with as little effort as possible. New materials, which we certainly still need are selected on the lowest possible environmental impact. Why not let ABT advise you on the right material choices and building physics concerns when applying bio-based and low CO2 materials.

Biobased materiaal in The Natural Pavilion

CO2 emissions from new materials in a project are about 75% of the emissions during the total life cycle. It is therefore critical to be the first to reduce this embodied CO2. This can be done by reusing parts of existing buildings as much as possible and prioritizing materials that belong to biological cycles.

Absorption of CO2

Bio-based materials are natural materials such as wood, stone and plant products that can retain CO2 over time. They reduce the overall ecological footprint of the building and contribute to a sustainable environment. Combined with a biophilic design approach, using more natural environments in buildings to create more connection with nature, we support the health and well-being of the occupants or users.

Prevention of decay

Because there are also some critical concerns when using bio-based materials, a building physicist will be involved in the design of a safe structure.

Bio-based materials are usually biodegradable. This makes them susceptible to moisture, mould, insects and erosion. This can affect the life of the material and the health of the users. The material is often light. To achieve good sound insulation, we can advise on proper construction and details. When using wood, fire safety is an important aspect to consider.

We have designed several projects with CLT construction, including calculations on whether the application of bio-based materials can be used safely without decaying or rotting.

To make a strong statement and show that Paris-proof building is possible in 2022, we used bio-based materials in the pavilion at Floriade expo 2022. All construction materials are derived from biological processes and 100% removable and reusable.
