Ventilation
Queen's Building, de
Monfort University, Leicester, England (Short + Ford architects)
Addresses acoustic isolation
by ventilating separate acoustic zones with individual stacks
Cross-section of a hypothetical
educational facility with hybrid ventilation.
1. Natural ventilation through
open windows during mild weather.
2. South-oriented solar
collectors or airflow windows preheat outdoor air during winter months.
3. Warm air is delivered
mechanically to north-oriented rooms.
4. Air is extracted by stack
effect through a central atrium.
5. Exposed thermal mass.
6. Glazed buffer zone admits
natural light and allows heat recovery of vitiated air before it is
extracted
outside by stack and/or Venturi effects.
7. NBC 90, art. 3.3.2.5.c)
allows unlimited operable window area between classrooms and
corridors
if room/exit distance is calculated from any point in the building.
