A ridge vent is a type of vent installed at the peak of a sloped roof which allows warm, humid air to escape a building's attic. Ridge vents are most common on shingled residential buildings. Ridge vents are also used in industrial warehouses to help release the hot air and help circulate comfortable air inside the building .
Historically, roof pitch was designated in two other ways: A ratio of the ridge height to the width of the building (span) [6] and as a ratio of the rafter length to the width of the building. [7] Commonly used roof pitches were given names such as: Greek: the ridge height is 1 ⁄ 9 to 1 ⁄ 7 the span (an angle of 12.5° to 16°);
Monitor roof: A roof with a monitor; 'a raised structure running part or all of the way along the ridge of a double-pitched roof, with its own roof running parallel with the main roof.' Butterfly roof (V-roof, [8] London roof [9]): A V-shaped roof resembling an open book. A kink separates the roof into two parts running towards each other at an ...
This is why UK Building Regulations require roofs to be ventilated, either by the use of soffit vents, ridge vents, or replacement ventilation slates or tiles. [7] A common method of ventilating a roof is to make openings in the soffit and ridge to allow natural air flow. This example also has ventilated exterior walls called rainscreen ...
The stack effect or chimney effect is the movement of air into and out of buildings through unsealed openings, chimneys, flue-gas stacks, or other purposefully designed openings or containers, resulting from air buoyancy.

On Dec. 6, the family received a phone call from immigration authorities and they were told to report to an office in Greenspoint, Texas, four days later to discuss Salazar-Hinojosa's case ...
In comparison to classic displacement ventilation (DV) systems [9] that deliver air at low velocities, typical UFAD systems deliver air through floor diffusers with higher supply air velocities. In addition to increasing the amount of mixing (and therefore potentially diminishing the ventilation performance compared to DV systems), these more ...
