MECHANICAL & ELECTRICAL PLAN VIGNETTE
General Tips for Taking Mechanical & Electrical Plan DirectionsComplete the partially completed reflected ceiling plan on thework screen by (1) providing a grid for acoustical tile, (2) locat-ing lighting fixtures to achieve specified light intensity, and (3)developing a schematic HVAC plan complete with fire dampersand air diffusers, ductwork, and return-air grilles to meetspecified air distribution requirements. It is recommended thatthe ceiling layout be completed before ducts are added. Yoursolution must be contained within the perimeter walls of theoverall space.
The completed plan should reflect effective coordination andintegration of structural, mechanical, and electrical units withinthe ceiling grid and should provide for maximum flexibility forfurniture layouts at the most economical cost.
Before beginning your solution, you should review theprogram information and lighting diagrams that can beaccessed through the Vignette Index screen and familiarizeyourself with the partially completed plan on the work screen.
ProgramA reflected ceiling plan for an architect’s office is to beprepared. The space is in a multistory building and isenclosed by leaseable office space on one side, a corridoron another, and two exterior walls. The client wants flexibilityfor furniture placement, efficient lighting levels, and acomfortable environment.

Comply with the following requirements to develop thereflected ceiling plan:
Suspended Ceiling System1. Provide a 2 ft X 4 ft grid with lay-in acoustical tiles
in all spaces.2. All ceiling heights are 9 ft above the finished floor.3. Typical walls terminate 6 inches above the finished ceiling;
bearing walls and fire-rated walls extend to the bottom ofthe floor deck above.
Lighting SystemLighting layouts should be efficient and should minimizeoverlighting and underlighting.1. For all spaces, use only recessed fluorescent fixtures to
provide uniform light distribution with a light level ofapproximately 50 footcandles measured at desk level(3 ft above the finished floor).
2. In addition to the fluorescent fixtures required above,provide recessed accent light fixtures.� Locate the accent light fixtures along the west wallof the Architect’s Office so that the direct light levelon the wall at a height of 5 ft above the floor is 80footcandles.
� Space the accent light fixtures so that the lightlevel between the fixtures at 5 ft above the floor is80 footcandles.
� The accent light fixtures should not be considered indetermining the uniform light distribution levels.
� The recessed fluorescent fixtures should not beconsidered in determining the accent light levels.
HVAC SystemThe space is served by the supply andreturn risers within the shaft indicated onthe floor plan. The HVAC system shouldprovide for uniform air distribution withan economical duct layout conforming tothe following restrictions:1. Provide a minimum of one supply
diffuser and one return-air grille ineach space. An acceptable airdistribution pattern includes onesupply diffuser and one return-airgrille for every 144 ft2 of floor area(or portion thereof ) in each space.
2. Connect each supply diffuser tothe rigid supply duct system withflexible duct.� Do not exceed 10 ft forflexible duct lengths.
3. Return-air grilles are open to theceiling space, which serves as areturn-air plenum.� Connect the plenum to thereturn riser with rigid duct.
4. Protect duct openings in fire-ratedwalls with fire dampers.
5. Flexible ducts fit through joist webs.6. Rigid ducts fit under beams, in
spaces between joists, and in azone that extends 2 ft on eitherside of beams and bearing wallsin plan view.� Rigid ducts do not fit through joists orbetween the bottom of joists and the ceiling.

MECHANICAL & ELECTRICAL PLAN VIGNETTE - Sample Passing Solution
The best way to solve this vignette is to start with the ceilinggrid, keeping the possible light spacing in mind. This solutionhas the correct number of supply diffusers and return-air grillesin each room and the lighting is spaced correctly throughout.All supply diffusers are connected to the rigid supply duct withflexible duct. All flexible duct runs are shorter than the 10-footmaximum allowed and serve a single diffuser. While the rigid
ducts may run anywhere parallel (and between) the joists, theymay not run perpendicular to the joists except within two feetof bearing walls or beams. This solution resolves that correctly.Fire dampers provided at the chase penetrations are orientedcorrectly, and the return duct properly extends into theplenum area.

Rigid return ductonly needs to pene-trate wall as shown.
Recessed accentlighting is usedwhere requiredby program.
Correct separation ofsupply diffusers andreturn-air grillesshown throughout.
Correct use of firedampers in ratedwall.
Rigid ducts thatrun perpendicu-lar to joists mustbe within 2'-0" ofbeam or bearingwall.
Procedural Tips� Familiarize yourself with thecontents of each layer by turningthe layers on and off.
� There are three ways to realign aceiling grid.� Use themove,adjust tool andclick anywhere within thegrid to shift the cells withinthe perimeter of the gridrectangle.
� Use themove,adjust tool andclick on an edge of the gridrectangle to increase ordecrease the length or widthof the entire grid rectangle.
� Use themove group tool andclick on any part of the grid tomove the entire grid rectangleelsewhere.
� The rotate tool in this vignetteworks without the wand. To rotatean element:� Click on the rotate icon.� Click on the element you wantto rotate. If it is rotatable, it willrotate 90 degrees every timeyou click on it.
� The rotate tool will change theorientation of the ceiling grid.
� When elements overlap, you mayhave trouble selecting a particularelement. If this happens, keepclicking (without moving themouse) until the desired elementhighlights.

MECHANICAL & ELECTRICAL PLAN VIGNETTE - Sample Failing Solution
The rigid duct runs perpendicular to the joists farther than twofeet from the beam along the north wall. The ConferenceRoom only has one supply diffuser and one return-air grillewhen two of each are required by the area calculation givenin the program. The one supply diffuser provided in theReception/Secretary area sits directly under the rigid duct but
is not connected by flex duct as required. In the DraftingStudio, the flex duct is also used to connect two supplydiffusers in a series which is prohibited by the program. Thelights are spaced too far apart in some locations to achievethe required lighting levels.
