Promoting a circular economy through a targeted choice of materials

MATERIALS

We promote the circular economy through forward-looking planning and the clever use of construction materials.

Wood is highly relevant for Zug Estates as a building material, not only because it has a low grey energy rating but also because it binds carbon for its entire useful life.

20 percent of rentable space is in wooden structures.

Our objectives

Deconstruction

We minimise the number of existing buildings to be deconstructed. Deconstructed material will be re-used on site whenever possible or recycled.

Choice of materials

Both recyclability and grey energy will be taken into consideration in the choice of materials. If recycled materials are available, they will be prioritised.

Planning

Digital planning, lean management practices including prefabrication and the use of smart connection techniques establish the conditions needed for these materials to be deconstructed and re-used or recycled in the future.

Reduction in interest, earlier rental income

Cost and scheduling certainty

High degree of detail possible during planning

Higher quality

Prefabrication in a protected facility

Weight reduction

Lower foundation costs if the subsoil is bad

Low level of building moisture

Better indoor climate and reduced construction time

More floor space

More floor space thanks to slimmer construction

BIM

Suitable for building information modelling

Conserve resources

Wood is a naturally renewable resource
