2. Heat and smoke vent - Wikipedia

   en.wikipedia.org/wiki/Heat_and_smoke_vent

   The majority of guidance available for design of heat and smoke building vents installed in buildings is restricted to nonsprinklered, single-story buildings. [4] This is partly a historical consequence of the installation of heat and smoke vents following the August 1953 General Motors, Livonia, MI major fire in a nonsprinklered manufacturing facility which effectively stopped the production ...

3. Ridge vent - Wikipedia

   en.wikipedia.org/wiki/Ridge_vent

   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 .

4. Building airtightness - Wikipedia

   en.wikipedia.org/wiki/Building_airtightness

   An airtight building has several positive impacts [3] when combined with an appropriate ventilation system (whether natural, mechanical, or hybrid): [4] Lower heating bills due to less heat loss, with potentially smaller requirements for heating and cooling equipment capacities; Better performing ventilation system

5. Attic - Wikipedia

   en.wikipedia.org/wiki/Attic

   One common code requirement is that the total area of attic vents be equal to or greater than 1/150 of the floor area of the attic, with 50 percent or more of the vent area located in the upper portion of the attic. Vents and louvers should face away from prevailing winds to keep out driven rain. Soffit vents under the eaves normally provide ...

6. Ventilation (architecture) - Wikipedia

   en.wikipedia.org/wiki/Ventilation_(architecture)

   An early method of ventilation was the use of a ventilating fire near an air vent which would forcibly cause the air in the building to circulate. English engineer John Theophilus Desaguliers provided an early example of this when he installed ventilating fires in the air tubes on the roof of the House of Commons.

7. Blower door - Wikipedia

   en.wikipedia.org/wiki/Blower_door

   Blower door tests are used by building researchers, weatherization crews, home performance contractors, home energy auditors, and others in efforts to assess the construction quality of the building envelope, locate air leakage pathways, assess how much ventilation is supplied by the air leakage, assess the energy losses resulting from that air ...

8. Stack effect - Wikipedia

   en.wikipedia.org/wiki/Stack_effect

   Some buildings are designed with strategically placed openings at different heights to induce the stack effect where cool air enters through low-level windows or vents, and warm air escapes through higher-level openings like skylights, roof vents, or clerestory windows.

9. Uniform Plumbing Code - Wikipedia

   en.wikipedia.org/wiki/Uniform_Plumbing_Code

   Designated as an American National Standard, the Uniform Plumbing Code (UPC) is a model code developed by the International Association of Plumbing and Mechanical Officials to govern the installation and inspection of plumbing systems as a means of promoting the public's health, safety and welfare.
