Free Information Service

Reducing energy use should always be the first step. Energy conservation has been one of our main areas of work ever since CAT started back in the 1970s. Over time we moved to the use of natural and renewable materials, to reduce pollution and carbon emissions. We offer advice and publications on these low-impact eco-renovation options. You can visit CAT to attend an in-depth course, or see examples of renovation techniques.
