thermic conditions

• nature of heat transmission, i.e. heat radiation
• temperature of air/wall, less than 2°C difference
• humidity, at least 40 %, ideal is 60 % humidity at 20° C
• air current < 0,1 m/s

quality of the air

• through heat radiation no raising of dust
• ionisation leads to deep breathing, relaxation
• no smouldering on hot surfaces

sound, noise

• elemental experience of fire, giving warmth and light

room design
