In December 2013, a new regulation regarding thermal insulation, aiming to improve building energy efficiency, came into force. It dictates which types of material must used in building insulation regarding roofing, walls, windows and floorboards. The construction sector is one of the country’s most significant energy consumers. As a result, the new regulation is considered an important first step in reducing its levels of consumption. Builders will have a transition period of one year to comply with the new rules and their failure to do so will result in construction permits being refused.
