Passive Design

Strategies

Passive Cooling-natural ventilation

-apertures for cooling : open shapes, size,

type

Building Orientation

-good orientation minimize energy load

& maximize free energy from sun and

wind

Buiding Masses -building program

-angled roof-overhangs structure-aerodynamic curves

Passive Heating-direct solar gain-Trombe wall :

optimizes heat gain and minimizes heat

loss during cold times, and avoids excess heat gain in hot

times.
