By passive cooling we mean the reduction of the overheating of a space through thermal control with natural cooling techniques.
Construction of buildings that incorporate passive cooling techniques into the construction.
These techniques are based on thermal control or on the reduction of excess heat before accumulation.
Building thermal control techniques are based on:
Solar control
- site shading
- surfaces with low emissivity
- insulation and thermal inertia
- screens on the windows
Convective control
- use of thermal inertia
- reduction of hot air infiltrations
Internal earnings control
- use of high-efficiency electrical equipment, energy class of level A, A + (refrigerator, washing machine, dishwasher, etc.)
Thermal control:
reject the heat coming from outside before it reaches the space to be air conditioned or reduce the amount of heat produced inside a building.
Dissipative or natural cooling:
dissipate excess heat through the use of natural thermal sinks
