Write about the changes in designs of building

Healthy building materials, using renewable resources where possible, while keeping non-renewable resources in high-quality material cycles. Instead of using building products that emit harmful indoor or outdoor emissions, only healthy and environmentally sound materials should be used within a given building context. This will require some assistance in selecting materials during the building and product design. Furthermore, as the existing building industry still uses a lot of primary and fossil resources, more efforts are needed to increase the use of secondary resources coming from high-quality recycling within the design of building components in order to reduce the need for primary resource extraction.

  The future role of building and product designers needs to be redefined. If buildings are more and more conceived as adaptable configurations (of standard building components) made of building kits such as Lego® and Meccano®, designing and constructing buildings can become accessible to more stakeholders, not only architects. This can be compared with the Do It Yourself (DIY) furniture concept, in which consumers can design and make their own tailored wardrobes/kitchens without the help of a specialised Similar observations can be made in product design: with the uptake of 3D printing, the manufacturing of customised user products has become accessible and will gain importance in the coming years.

  Standardisation of connections and dimensions of components will require a long and difficult harmonisation process within the building industry, because some producers will need to change their design and production processes.

  Reversible Building Design and Circularity is not rewarded today, as designer fees are calculated based on current building costs, not taking into account future costs/savings when the building needs to be adapted or refurbished. Unless solutions supporting adaptability, multi-use, reuse and disassembly are put forward by the building client, e.g. through a design brief, there is hardly any (financial) incentive for building designers to incorporate these principles into the design. Even more, the enlarged responsibility of the designer to take into account the entire life cycle of the building and building products, can be perceived as an extra burden within the design stage, and not as an opportunity.
