  2. Air gap (plumbing) - Wikipedia

    en.wikipedia.org/wiki/Air_gap_(plumbing)

    Water cannot flow from the sink to the tap in normal circumstances, even if the water supply loses pressure. An air gap, as related to the plumbing trade, is the unobstructed vertical space between the water outlet and the flood level of a fixture. [1]

  4. Grease trap - Wikipedia

    en.wikipedia.org/wiki/Grease_trap

    Interceptors require a retention time of 30 minutes to allow the fats, oils, grease, and food solids to settle in the tank. As more wastewater enters the tank, the grease-free water is pushed out of the tank. The rotting brown grease inside a grease trap or grease interceptor must be pumped out on a scheduled basis.

  5. Autodesk Revit - Wikipedia

    en.wikipedia.org/wiki/Autodesk_Revit

    Autodesk Revit is a building information modeling software for architects, structural engineers, mechanical, electrical, and plumbing (MEP) engineers, and contractors. The original software was developed by Charles River Software, founded in 1997, renamed Revit Technology Corporation in 2000 and acquired by Autodesk in 2002.

  6. Building information modeling - Wikipedia

    en.wikipedia.org/wiki/Building_information_modeling

    Building information model of a mechanical room developed from lidar data. Building information modeling (BIM) is an approach involving the generation and management of digital representations of the physical and functional characteristics of buildings or other physical assets and facilities. BIM is supported by various tools, processes ...

  7. Trap (plumbing) - Wikipedia

    en.wikipedia.org/wiki/Trap_(plumbing)

    Water enters at right, fills the trap, and continues left. Inverted siphoning occurs below the line "A". Examples of traps [further explanation needed] In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass ...

  8. Hydraulic shock - Wikipedia

    en.wikipedia.org/wiki/Water_hammer

    Reduce the pressure of the water supply to the building by fitting a regulator. Lower fluid velocities. To keep water hammer low, pipe-sizing charts for some applications recommend flow velocity at or below 1.5 m/s (4.9 ft/s). Fit slowly closing valves. Toilet fill valves are available in a quiet fill type that closes quietly.

  9. Building performance simulation - Wikipedia

    en.wikipedia.org/wiki/Building_performance...

    Building performance simulation has various sub-domains; most prominent are thermal simulation, lighting simulation, acoustical simulation and air flow simulation. Most building performance simulation is based on the use of bespoke simulation software. Building performance simulation itself is a field within the wider realm of scientific computing.
