Reflected Ceiling Plans

This electrical floor plan sample shows the lighting layout on the classroom reflected ceiling plan.
"Architectural lighting design is a field within architecture and architectural engineering that concerns itself primarily with the illumination of buildings. The objective of architectural lighting design is to obtain sufficient light for the purposes of the building, balancing factors of initial and operating cost, appearance, and energy efficiency. Lighting designers are often specialists who must understand the physics of light production and distribution, and the physiology and psychology of light perception by humans. Architectural lighting design is generally concerned with the permanent illumination of a structure. Concert and theatrical lighting have different purposes and practitioners."

The electrical floor plan example "Classroom lighting - Reflected ceiling plan" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Electric and Telecom Plans solution from the Building plans area of ConceptDraw Solution Park.

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 PRO diagramming and vector drawing software extended with the Reflected Ceiling Plans solution from the Building Plans area of ConceptDraw Solution Park.

The vector stencils library Registers, drills and diffusers contains 47 symbols of rectangular, circular, linear and troffer air handling inlet/ outlet components.
Use the design elements library Registers, drills and diffusers to draw reflected ceiling plans (RCP) and HVAC layout floor plans using the ConceptDraw PRO diagramming and vector drawing software.
"A ceiling is an overhead interior surface that covers the upper limit of a room. It is not generally considered a structural element, but a finished surface concealing the underside of the floor or roof structure above.
Ceilings are classified according to their appearance or construction. A cathedral ceiling is any tall ceiling area similar to those in a church. A dropped ceiling is one in which the finished surface is constructed anywhere from a few inches to several feet below the structure above it. This may be done for aesthetic purposes, such as achieving a desirable ceiling height; or practical purposes such as providing a space for HVAC or piping. An inverse of this would be a raised floor. A concave or barrel shaped ceiling is curved or rounded, usually for visual or acoustical value, while a coffered ceiling is divided into a grid of recessed square or octagonal panels, also called a "lacunar ceiling". A cove ceiling uses a curved plaster transition between wall and ceiling; it is named for cove molding, a molding with a concave curve." [Ceiling. Wikipedia]
