This RCP sample was drawn on the base of the prototype bathroom plan from the website of the Oregon Department of Human Services (DHS), USA.

"A bathroom is a room for personal hygiene, generally containing a bathtub or a shower, and possibly also a bidet. In North America and some other regions, it characteristically contains a toilet and a sink; hence in North American English the word "bathroom" is commonly used to mean any room containing a toilet, even a public toilet (although in the United States this is more commonly called a restroom). In other countries, including the UK, Australia, France and Japan, homes may have a separate toilet. In Iran almost all homes have two distinct rooms for bathroom and toilet room." [Bathroom.

The reflected ceiling plan example "RCP - Prototype bathroom design" was created using the ConceptDraw DIAGRAM diagramming and vector drawing software extended with the Reflected Ceiling Plans solution from the Building Plans area of ConceptDraw Solution Park.

This HVAC floor plan sample shows the ventilation duct system layout.
"Ducts are used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, supply air, return air, and exhaust air. Ducts commonly also deliver ventilation air as part of the supply air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort.
A duct system is also called ductwork. Planning (laying out), sizing, optimizing, detailing, and finding the pressure losses through a duct system is called duct design." [Duct (flow). Wikipedia]
