Abstract
The Finnish Society of Indoor Air Quality and Climate (FiSIAQ) introduced a Classification of Indoor Climate, Construction Cleanliness, and Finishing Materials in 1995. The Classification of Indoor Climate has been revised to meet the new Decree on indoor air quality and ventilation, European standards and experience from users of the classification. The most significant change is that target values for concentration and the in/out ratio of fine particles have been added. Other adjustments have been made to ensure good indoor environment and energy efficiency, but with reasonable investments. The criteria for emissions from building material and furniture were also updated. The Building Information Foundation RTS sr has run the M1-labelling of building products since 1996. The voluntary approach has been proven to improve the IAQ in new buildings and to reduce emissions from building materials. The Classification of Indoor Environment 2018 is integrated part of the new RTS Environmental Classification system.
Highlights
Good indoor environment is one of the most important objectives of construction
The Classification of Indoor Environment 2018 has been updated based on user experience and latest research knowledge
S1 category: Individual indoor environment The indoor air quality of the space is very good and there are no detectable odours in the environment
Summary
Good indoor environment is one of the most important objectives of construction. Indoor climate quality is affected by heating, ventilation, and airconditioning equipment; construction engineering; the quality of the construction work; building materials; and the use and maintenance of the building. Good indoor environment requires taking all these elements into consideration in all stages of the design, construction, and use of the building. First part of The Classification of Indoor Environment (CIE) 2018 [1] include new Requirements for Technical Target Values. The classification is intended for the setting of indoor air targets concerning usual work and occupied spaces (including office and public buildings, schools, day-care centres, dwellings). The Classification of Indoor Environment 2018 has been updated based on user experience and latest research knowledge. It takes into account the requirements by the Ministry of Social Affairs and Health [2] and the Ministry of the Environment [3], as well as changes in European standards
