Passive Cooling Floor Vents

Use this green technique to reduce kitchen humidity and warm the spare room.

Passive cooling floor vents.

Insulation is critical to passive cooling particularly to the roof and floor. Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems it refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces. Windows are often left open to take advantage of natural cooling and walls are easily shaded. This helps to provide cooling as well as removing moisture and airborne pollutants.

Roofs however are difficult to shade and floors are a source of constant heat gain through conduction and convection with only limited cooling contribution to offset it. Passive ventilation uses doors windows opening skylights and clerestory windows vents louvres and other openings to let fresh air into and through your home. There are two types of natural ventilation occurring in buildings. A passive vent is placed in a wall or a floor enhancing air flow without burdening fuel powered ventilation systems.

By using key natural ventilation strategies to ventilate during the day or night night cooling mixed mode ventilation reduces the use of mechanical systems and possibly the size of the system. Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. This approach works either by preventing heat from entering the interior heat gain prevention or by removing heat from the building natural cooling.
