INDOOR CLIMATE
Thermal indoor climate Air temperature, air velocity and air humidity
Atmospheric indoor climate:
= Air quality: pollutions as dust, air humidity, gasses and smell The psychical environment

INDOOR CLIMATE
Physical and chemical demands for the indoor climate
1. Suitable temperature 2. Suitable air humidity 3. Suitable air replacement 4. Suitable lighting conditions 5. Suitable sound conditions 6. Absence of negative indoor climate elements

Indoor climate and ventilation
Negative indoor climate elements
1. Dust, breathable or non- breathable 2. Fibres, e.g. from textiles, mineral wool and asbestos 3. Biological material, e.g. fungus spores, alga, pollen, bacteria etc. 4. Smoke, e.g. from tobacco 5. Degassing, e.g. from building materials, inventory and cleaning materials 6. Obnoxious smells, e.g. from external environment 7. Entrances from the underground structure, e.g. radon or leaking out from chemical depots 8. Static electricity, e.g. because of floor coverings 9. Vibrations and heavy noise, e.g. from big machines or traffic

Indoor climate and ventilation
Principles for heating and ventilation systems
The above mentioned terms are what we use in connection with ventilation systems. Heating- and ventilation in connection with industrial buildings is different compared with, what we have been dealing with in the earlier semesters. It has been domestic buildings, where the demands for heating and ventilation normally can be found in the Building Regulations. When it is about other buildings than domestic buildings, we are referred to, that it should be approved by the local authorities in consideration of the size of the room and its use. Furthermore is referred to DS 447: Code of
