Ceilings & Lighting

This section will introduce you to working with ceilings and the placement of lighting.

Lights and other ceiling mounted objects are hosted by ceilings. You may have inserted a second floor which has a ceiling finish at the bottom, but Revit requires that you insert a separate ceiling component to serve as a host for your ceiling mounted objects. 

CL.1. Inserting the Ceilings

CL.1.1. Before inserting a new ceiling you need to check the thickness and assembly characteristics of your floor assembly. In the image below the floor assembly on Level 2 was selected while in a section view. To determine the thickness of the assembly, the Edit Type button was selected. Then the Edit button next to Structure was selected.

CL.1.2. In the image below we can see that the total thickness of the floor is 1'-0 3/4". Also, we can see that there is no finish material assigned as a finish below the structure layer.  So we can add a ceiling layer that would be installed below the structure. Keep in mind that you will need to check the thickness for the roof assembly when you begin adding ceilings and lights to the upper level. The roof thickness will likely be different than the floor assemblies.

CL.1.3. Insert a layer of gypsum wall board for your ceilings. Note that the ceiling finish varies for different types of projects. The Compound Ceiling GWB on Mtl. Stud, for example, is typically used for a hung ceiling that is separated from the floor structure above. This is common for commercial and institutional ceilings. The hung ceiling type would not be included in the floor assembly, but would be inserted as a separate assembly.

As shown below the new thickness for the assembly is 1'-1 3/8".

CL.1.4. Go to the Ceiling View for a level that will have ceilings and lighting. The Level 1 ceiling will be the ceiling below the second level floor as shown in the images above.

CL.1.5. Go to the Ceiling tool located on the Architecture ribbon.

CL.1.6. Create a duplicate ceiling type using the Basic Ceiling Generic as a template.

CL.1.7. Give a name to your ceiling. In the image below the new ceiling has been named Paint Coating.

CL.1.8. Click on the button in the Material row and below Value to change the material type from the default to Paint. In the image below paint has been assigned to the ceiling.

CL.1.9. The Material Browser should appear. If you search for paint, you should see that the only item currently loaded is Parking Stripe. Click on AEC Materials and search for Paint. Change the appearance as you would like.

CL.1.10. Begin placing ceilings in the various spaces.

Keep in mind that the ceiling must be below the floor assembly. In this example, the floor assembly is 1'-1  3/8" thick. The ceiling component will be a layer of paint and will bet set 1/8" below the floor assembly. If the floor to floor height is 9'-0" and the ceiling is 1'-1  3/8" thick, then by ceiling height will be 7'-10 1/2". This will place it just below the floor assembly above. You can change the height of a ceiling by selecting it and changing its height in the Properties window.

Be careful not to insert a ceiling on top of another ceiling.  You will receive a warning if this occurs. You can delete the duplicate ceiling. 

In the image below a ceiling has been drawn. The height has been set so it is below the floor assembly.

CL.2. Ceiling Mounted Lighting

CL.2.1. Inserting lights is similar to inserting other types of components. Ceiling mounted lights are inserted in the Ceiling views and must have a ceiling host.

CL.2.2. Choose your lights from the Architectural folder. The fixtures in the MEP folder are intended for Revit MEP instead of Revit Architecture that we are using.

CL.2.3. The External folder contains lighting for building exteriors (you may have these too). The Internal folder contains lighting for interiors.

CL.2.4. Choose a fixture family from the list. The Downlight- Recessed Can fixture selected below is a recessed incandescent light. 

CL.2.5. The process for placing a light is similar to inserting other components.

CL.2.6. Insert lights in the rooms of your project. You may find that the grid intersections are useful to position your lights. If your ceiling is below the floor assembly, the lights should appear in your ceiling plan.

Note that if you render the room, the lights may not appear. This is because they are blocked by the floor assembly. You can hide the floor element and render the view. The lights should render in that case.

CL.3. Floor and Wall-mounted Lighting

CL.3.1. Some fixtures do not require a ceiling to serve as host. Wall sconces are hosted by wall components. Floor lamps can be placed on floors in the floor plan views.
