Wales Institute for Sustainable Education

The Wales Institute for Sustainable Education (WISE) is an educational building located at the Centre for Alternative Technology near Machynlleth, Powys, Wales. It was designed as a case study for sustainable architecture and green building and has won several awards.

The building was designed by architects Pat Borer and David Lea and inaugurated in June 2010. It contains a 200 seat lecture theatre, offices, teaching rooms and 24 en-suite bedrooms. WISE was designed to demonstrate the use of ecological building principles such as passive solar building design and heat recovery ventilation and uses building materials which have a low embodied energy.

The main materials used in constructing the building were wood, hemp, lime and rammed earth. The external walls of the building are made from 500mm thick hempcrete, and the 7.2m high walls of the lecture consist of 320t of rammed earth.

A building management system is used to monitor a wide variety of parameters inside the building, providing data for research projects by CAT's sustainable architecture students.

The building is used for teaching a wide variety of short courses, and postgraduate university degrees through the Centre for Alternative Technology's Graduate School for the Environment, including Master's degree level courses in renewable energy and sustainable architecture.
