The 1989 ASHRAE standard (Standard 62–89) states that appropriate ventilation guidelines are 20 CFM (9.2 L/s) per person in an office building, and 15 CFM (7.1 L/s) per person for schools, while 2004 Standard 62.1-2004 has lower recommendations again (see tables below).
Displacement ventilation systems supply air directly to the occupied zone.The air is supplied at low velocities to cause minimal induction and mixing. This system is used for ventilation and cooling of large high spaces, such as auditorium and atria, where energy may be saved if only the occupied zone is treated rather than trying to control the conditions in the entire space.
A wooden window grill in Plaza del Conde del Real, Valencia ().The structure was probably used as a stable. Grille, and control for an air duct.

The Biden administration will announce new building ventilation standards for schools and businesses on Thursday -- a welcome step for experts who feel the U.S. has long been behind the curve on ...
Usually, a register is placed near a window or door, which is where the greatest heat/cooling loss occurs. [4] [5] In contrast, returns (grilled ducts which suck air back into the HVAC system for heating or cooling) are usually placed in the wall or ceiling nearest the center of the building. Generally, in rooms where it is critical to maintain ...
The White House released new ventilation and air quality guidelines for schools, colleges and other building owners and operators, in an effort to reduce the risk of Covid-19 spreading indoors.
An airtight building has several positive impacts [3] when combined with an appropriate ventilation system (whether natural, mechanical, or hybrid): [4] Lower heating bills due to less heat loss, with potentially smaller requirements for heating and cooling equipment capacities; Better performing ventilation system
ASHRAE Standard 62.2 was adopted in 2004; it clarifies the ventilation air requirements for low-rise residences. The Standard specifies that forced ventilation is required in houses with infiltration less than 0.35 ACH. [2] This is typically accomplished with heat recovery ventilation or exhaust fans running constantly or periodically.
