curvature of e.g. plasterwork to fill the space above the kitchen cabinets, at the corner of the ceiling and wall: coving (interior design) underside of office ceiling of tiles (often gypsum) suspended, fastened or bonded to a grid system attached to the walls and/or ceiling: false/suspended ceiling (tiles/grid) or dropped ceiling
Vertical section through a commercial building using HVAC plenum instead of airspace plenum. When both the supply and return ducts are constructed in this manner, it is possible to insulate the ducts and the dropped ceiling so that the upper airspace is not heated or cooled, increasing energy efficiency. This is a fully enclosed plenum.
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 .
Smart ventilation can time-shift ventilation to periods when a) indoor-outdoor temperature differences are smaller (and away from peak outdoor temperatures and humidity), b) when indoor-outdoor temperatures are appropriate for ventilative cooling, or c) when outdoor air quality is acceptable.
A register is a grille with moving parts, capable of being opened and closed and the air flow directed, which is part of a building's heating, ventilation, and air conditioning (HVAC) system. The placement and size of registers is critical to HVAC efficiency. Register dampers are also important, and can serve a safety function.
Cross ventilation (single spaces): Being unsophisticated and efficacious, this type of ventilation is a horizontal process that is driven by pressure differences between the windward and leeward sides of the occupied indoor environment. Ventilation here is generally provided using windows and vents at either side of a building where the ...
Roof shapes include flat (or shed), gabled, hipped, arched, domed, and a wide variety of other configurations detailed below. [1]Roof angles are an integral component of roof shape, and vary from almost flat to steeply pitched.
Ceiling-mounted: Mounted in the ceiling between the attic and living space. Ducted: Remotely mounted away from the ceiling, typically hung from the rafters; can exhaust heat from multiple locations; operation is usually quiet compared to traditional whole-house fans. Window-mounted: Mounted in a window frame. Can also take cool air in from outside.
