01 Bio architecture
What is bio architecture?
index
sources of indoor pollutants
How does ventilation in an apartment work?
key
fresh indoor air inlet
openings enable for air flow
(i.e. doors undercuts, grilles in walls)
exhaust air outlet
the amount of outdoor air that is provided into the space, and the quality of the outdoor air
ventilation rate
the overall airflow direction in a building, which should be from clean zones (living rooms, dining rooms, bedrooms, to dirty zones (kitchen, bathrooms)
airflow direction
how fresh indoor air is distributed through the space
air distribution or airflow pattern
How to make air flow?

ventilation
depth<2.5 times height
design that favours ventilation
< 10 m
depth<5 times height
distance between rooflights<5 times height
1. Wind direction and velocity;
2. Building opening locations and size;
3. Temperature differentials (internal and external).
Have in mind
natural ventilation strategies
Wind towers: still used in some areas of Middle East and Egypt
Canadian wells or Provençal wells: takes advantange
of geothermal energy
Trombe wall: free heating with solar energy
