Why is limiting indoor negative pressure important?

Limiting indoor negative pressure is important because it enhances comfort and energy efficiency in a building. When a space has negative pressure, it means that the air pressure inside is lower than outside, which can lead to uncontrolled air leakage. This can cause drafts, discomfort, and increased energy consumption as the heating and cooling systems work harder to maintain the desired indoor temperature.

By maintaining a balanced or slightly positive pressure, buildings can minimize drafts and reduce the amount of conditioned air that escapes. This not only leads to improved occupant comfort but also results in better energy efficiency, as it helps to keep heating and cooling costs lower by reducing the workload on HVAC systems.

In essence, a well-managed indoor pressure environment ensures that air moves appropriately through the space, promoting both comfort for the occupants and efficiency in energy use.
