1 The Finnish Classification of Indoor Environment and Material Emissions Jorma Säteri Finnish Society of Indoor Air Quality and Climate, FiSIAQ

2 Finnish Classification of Indoor Environment 2008 An update of the classification first published in 1995 and revised in A voluntary system for setting target values for indoor environment in new construction

3 Finnish Classification of Indoor Environment Target values for indoor air quality and climate, acoustics and lighting (S) Instructions for design and construction (P) Requirements for building products (M) Building and constructions HVAC systems Classification of emissions from building materials Classification of clenliness of ventilation components

4 Target values (S) Three categories S1 individual ~ cat I of EN15251 S2 comfortable ~ cat II S3 satisfactory building code level Specified from client s and engineer s viewpoints

5 Technical target values Operative temperature (EN applied in Finnish climate) Air velocity (based on EN ISO 7730) Carbon dioxide (based on EN 15251) Outdoor air flow rates (EN 15251, very low emitting buildings) Radon Lighting (based on SFS-EN :2003) Acoustics (based on SFS 5907)

6 Target values for operative temperature

7 Target values for operative temperature

8 Target values for operative temperature

12 Some target values have been replaced with prescriptive criteria VOC, ammonia, formaldehyde à use low emitting building materials Fine particles à use F9/F8 class filtration of supply air (EN 13779) Dust and dirt à criteria for cleanliness of surfaces of the new building Microbes à ensure good control of moisture in design and construction ETS à ban smoking indoors

13 Space usage profiles and internal heat loads

14 Design values for HVAC systems

15 Dimensioning of outdoor air flows According to EN-15251:2007 Design values for very low emitting buildings can be used when the guidance of the classification is followed Cat S1: 0,5 l/s,floor-m l/s, person Cat S2: 0,5 l/s,floor-m l/s, person Control of room temperature or allowance for flexibility may require greater air flows Rremoval of contaminants from specific sources must be handled separately Air flows should be easily adjustable when the use of the space changes A basic ventilation of 0,1 0,2 l/s,m 2 must be in operation also outside normal working hours

16 Space Cat S1 Cat S2 Cat S3 Floor surface dm 3 /s per dm 3 /s per dm 3 /s per dm 3 /s per dm 3 /s per dm 3 /s per (m 2 /person) person m 2 person m 2 person m 2 Office space, normal space efficiency Office space, high space- efficiency Conference room Break room, canteen Hotel room Corridor and staircase Lift shaft Classroom Lecture room Corridor, school lobby Lobby Day- care centre Wet entrance at day- care centre (exhaust) Canteen and cafeteria Heating and distribution kitchen 1) Preparation kitchen Dishwashing room 1) Business space 1) Exhibition space Library

17 Building and constructions Instructions for construction client Instructions for design and selection of materials Classification of construction cleanliness Classification of cleanliness of ventilation systems includes requirement for supply air filtration Requirement for a moisture control plan

18 Instructions for structural design The following aspects shall be taken into consideration in structural design material emissions moisture characteristics easiness of cleaning durability performance requirements set by sandwich structures

19 Instructions for selection of materials The building materials should be as low emitting as possible. The building materials of a space designed according to indoor climate categories S1 and S2 should predominantly be selected from emission class M1. M2 classified building materials should not cover more than 20% of the interior surfaces of a room and never more than 1 m² per m² floor. Uncoated brick, stone, ceramic tile, glass and metal surfaces as well as untreated board and log surfaces (excluding hardwood) may be used freely.

20 Requirements for emission class M1 No changes are proposed to the M1 criteria of building materials TVOC < 0,2 mg/m 2 h Formaldehyde < 0,05 mg/m 2 h Ammonia < 0,03 mg/m 2 h Carcinogenic compounds Dissatisfaction with odour < 15 % 0.1 acceptability vote 1.0 Plasters and tiling products, levelling agents, putty, mastics, fillers, screeds and renders shall not contain casein. < 0,005 mg/m 2 h

21 M1 labelled products Today there are over 2100 labelled products by over 110 producers. The largest product groups: Plaster, rendering, putties, fillers, flooring, paints and varnishes, building boards and mineral wool. See for complete listing

22 Review of M1 criteria M1-labelling will be harmonised with other European labels Harmonisation of test methods with CEN/TS 16516:2013 Model room 30 m 3 Testing age 28 d Revised criteria for VOCs LCI values will be taken into use Sensory evaluation according to ISO , acceptability

23 Summary Following the instructions of the classification leads to better indoor environment The voluntary classification is widely accepted by the industry There are over 2100 M1-labelled products The system is developed based on EN and ISO standards, applied to Finland An update of the classification is due 2014
