On 11 October 2017, the Parliament’s Industry committee will adopt its report on the revision of the Energy Performance of Buildings Directive. With one in six Europeans living in unhealthy buildings, 2 million healthy years are lost in the EU every year due to poor indoor air quality. This review is a once-in-a-decade opportunity to drive much needed changes and improvements in the existing building stock and to promote systems and solutions that result in higher Indoor Environment Quality (i.e. indoor air quality, thermal comfort, lighting and acoustic environment), lower energy consumption and increase consumer empowerment.
