What is the stack effect?

The tank effect is a trend to move the warm air up in the building, driving circulation and creating pressure differences. The differences in air density are driven and must be taken into account when designing and maintaining structures. For very large buildings, such as skyscrapers, this can be a significant problem. For example, the tank effect can add to heating and cooling costs, for example by causing heat losses at the top of the building, especially in the cold winter months. This process can be accelerated by ventilation, including the opening of doors and windows, as well as lowering fans. In very high structures it can be particularly acute and to some extent inevitable. For upper stories, air can escape. This creates a positive pressure, because pushing air from the outside cannot get into the building due to the pressure of the escape air.LDing, the negative pressure environment is created. The air that pulls towards the roof creates an opening for colder air, which can move from the outside. This can cause lower stories to beu much cooler. In a poorly designed building, people can close windows and discover heat to solve it, which can speed up the effect of the stack by the heating air and force it at the top to escape, draw more cold air.

A certain air circulation is required. The movement of air inside the building can maintain fresher and make it a more pleasant working environment, especially when fresh oxygenated air cycles from the outside. Designers can control this by adding insulation to reduce air loss, install shielding on the windows to minimize heat transfer and advise passengers of climate control. For example, the lobby insulation to reduce cold air explosions, when people open the door, can help.

For homes and small structures, the effect of the magazine should not play an important role, unless the structure is well built or maintained. Some leaks are inevitable but the biggest problems,As leakage around window frames and skylights can be solved by measures such as better flicker. It can also help to design records and doors to discourage air flow into the house during the winter months. Due to the effect of the magazine, the design allows architects to create houses that remain ventilated but do not lose excessive heat.
