Revised Finnish classification of indoor climate 2018

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. , 0 (201 Web of Conferences

Indoor Air Quality: A Focus on the European Legislation and State-of-the-Art Research in Italy

“…Among the Nordic countries, in Finland, for example, the working group (coordinated by the Ministry of Social Affairs and Health (MSAH)), developed guide values for five pollutants: ammonia, carbon monoxide, carbon dioxide, hydrogen sulfide, and PM 10 . They were proposed in the decrees of the Ministry of the Environment Housing and Building Department D2 National Building Code of Finland-Indoor Climate and Ventilation of Buildings Regulations and Guidelines [27], which entered into force 1 October 2003. For the other pollutants, it is possible to derive guide values using 1/10 of the limits for industrial work environments (Occupational Exposure Limit, OEL).…”

“…The guide values for confined spaces apply to buildings that are occupied for at least six months and where the ventilation system is kept constantly on. Alongside these references are those developed by the Finnish Society of Indoor Air Quality and Climate Classification [27]. It is an initiative desired and financed by the Ministry of the Environment, in collaboration with the experts of the manufacturers and stakeholders of the materials sector, which led to the identification of the target values defined as S1 (individual indoor environment), S2 (good indoor environment), and S3 (satisfactory indoor environment) categories [27].…”

Performance of Modern Passive Stack Ventilation in a Retrofitted Nordic Apartment Building

“…In Finland, the building stock ventilation construction and design requirements are provided by the Ministry of Environment [3,6,7]. The documents consider new and retrofitted buildings separately as buildings of different ages present the stock [8].…”

Carbon dioxide effects on daytime sleepiness and EEG signal: A combinational approach using classical frequentist and Bayesian analyses

“…Several standards were proposed as the optimal indoor space CO 2 concentration. More specifically, ≤1000 ppm by the Ministry of Health Labor and Welfare (MHLW, Japan) 7 ; ≤0.10% (2000 mg/m 3 ) by Administration of Quality Supervision Inspection and Quarantine (AQSIQ, China Standard CS GB/T17094‐1997) 8 ; ≤800 ppm (excellent class/non‐residential) by the Hong Kong Special Administrative Region (HKSAR, China) 9 ; ≤1000 ppm by Department of Occupational Safety and Health (DOSH, Malaysia) 10 ; ≤1000 ppm by Guideline development for evaluation and management of office air quality (II) by Korea Occupational Safety and Health Agency (KOSHA) 11 ; ≤1000 ppm by Singapore Institute of Environmental Epidemiology (SAIQG) 12 ; and <550 ppm (good indoor air quality) by The Finnish Society of Indoor Air Quality and Climate (FiSIAQ) 13 …”
