Description

The manufacture of concrete is responsible for around 6% of global CO2 emissions. This workshop explores the use of low carbon alternatives to concrete and other commonly used building materials. It makes full use of CAT’s unique collection of sustainable buildings and also covers the basic material properties commonly required in building design.

The tour covers the history of the site and of CAT and introduces the key sustainability themes used on site from renewable energy through to a wide variety of examples of environmentally responsible buildings. The tour also takes in CAT’s beautiful organic gardens with an option to include the Quarry Trail walk which surrounds the site and provides stunning views of the site and the Dyfi Biosphere in which it lies.
