S14 From Start to Finish Electrical How - To for Revit MEP Projects-Joe Kerfoot

ID: 125 From Start to Finish: Electrical How-to for Revit MEP Projects 1:00PM-2:00PM

MEP – Intermediate

Short Description: Session Description: Do you feel like you are just scratching the surface with Revit MEP for Electrical projects? If so this course is for you. This course is designed to show you how to use Revit MEP from start to finish on a project for Electrical design. Revit MEP is a very powerful production and design tool but a lot of that functionality is underused because of the lack of out of the box families, parameters and schedules. I will show you how to make better models, streamline documentation, and produce better schedules on your Electrical Revit project with lots of how-tos and live demonstrations. Some of the features we will focus on will be: • Design Phase Considerations • General Electrical Considerations

o Settings o Equipment / Fixtures / Devices o Parameters • Device Schedule Usage & M/P Coordination • Circuiting / Panel Schedules / Load Analysis • Calculations o Photometric o Power Density • Tips / Tricks / and Problems This class is based around Revit MEP users who are looking to leverage the full capabilities of the software or gain understanding of tools they have no yet worked with.

General Electrical: Tutorials YouTube Training: There are a lot of individual training videos on YouTube at the kink below. http://www.youtube.com/watch?v=MdKDH5ZHBZY Just make sure that you search Revit MEP when on YouTube. Autodesk Tutorials: http://docs.autodesk.com/RVTMPJ/2011/ENU/landing.html

How to Learn

1.1

General Electrical: General Calculations Panel board Load Analysis: Refer to Panel Schedules section. Panel board Phase Balancing: Refer to Panel Schedule section. Wire Sizes per voltage drop: This is done automatically. Revit will find the longest distance between devices and source based on the Max voltage drop set in the electrical settings. Refer to Electrical Settings documents. Lighting Fixture Quantities: This will need some development. Using the space schedule, you can create an imbedded schedule to schedule the light fixtures in the space. Then you can define a parameter for each of the spaces that is associated with the ComCheck space classifications. You can group the spaces and automatically count the fixtures in each type of space for quickly entering into ComCheck. The thing to confirm is that the fixtures are actually mounted inside of the space. You may need to adjust the space height as the default is 8’. Electrical Equipment Starter Sizes: This would require some development, but the starter selection can be automatically calculated similar to the standard excel schedule for mechanical equipment. Electrical Equipment Fuse and Disconnect Sizes: This would require some development, but the fuse and switch selection can be automatically calculated similar to the standard excel schedule for mechanical equipment. Point to point Short Circuit: This is a rudimentary Point-To-Point calculation family that is in the template file. This family does not take into account transformer let-thru or large motor contributions. This is only used for simple system calculations. bimproductivity.com

1.3

General Electrical: General View Templates The view templates are instrumental in maintaining consistency of views. There are a few electrical default view templates set up in the template file. Ensure that you set the view templates the way that you want. If there are temporary modification that are needed, use “VG”, but then go back and “Apply Default Template to Current View” when you are finished. These view templates are used to control the project browser organization and the typical visibility in the views. When adding new views to the project, ensure that you map these view to the appropriate view template.

How to Learn

1.4

General Electrical: Items Needing Development There is one thing that is currently not functioning in the current panel schedule load analysis. The connected and calculated panel totals will not exclude the smaller of Heating or Cooling loads. This can be developed, but has not been at present. You would need to modify the panel schedule template and add below the Total Est. Demand. Add “Non-Coincident Heating/Cooling:” Then, use calculated value Name: HeatingCoolingNC; Discipline: Electrical; Type: Current Formula “if(heating estimated demand current > cooling estimated demand current, cooling estimated demand current, heating estimated demand current) Then add new total “Total Est. Demand – NC” New folrmula is “total estimated demand current – previous formula

Device Layout: Placing Devices

Before hosting and placing the devices, check the Properties window to insure that you are placing the correct device that you want to. Once the devices has been placed, check the “Constraints” section of the properties window. This is were you would indicate the TAG, mounting height, of the branch that the device is placed on.

How to Learn

2.1

Device Layout: Electrical Fixtures _e_tag PWR DEV – Circuit This is used if you want to have the circuit number placed adjacent to the receptacle. _e_tag PWR DEV – Description This is used for a general description of the fixture (misc. open for whatever). _e_tag PWR DEV – EM Branch This is controlled by the checkbox of the fixture properties (Critical = C, Life Safety = LS). _e_tag PWR DEV – Equipment This is a Mechanical formatted tag that is used when associating with Mechanical/Plumbing Equipment. _e_tag PWR DEV – Mounting This is a tag to indicate the Mounting Height. It is controlled in the properties of the device. This tag does not reflect the true mounting height in the model, just a tag. _e_tag PWR DEV – Special Equipment This is used for tagging special equipment (Copier, Fax, Ref., or Medical Equipment) anything that has a special load.

DO NOT USE TEXT!!!! How to Learn

2.2

Device Layout: Electrical Equipment Disconnects/Starters are used for powering the associated Mechanical / Plumbing Equipment. Panel boards or Transformers, you must define the “Primary” Distribution System as indicated below before you can start circuiting. For Transformers only, you will also need to select the Secondary Distribution System from the properties window. The default tag for this equipment is the Panel name. When placing these, the only additional information that you need to provide would be the branch from the checkboxes in the properties window (Critical, Life Safety, and Equipment).

Schedules: General Schedules The parameters in the schedules should be set and mapped for all of the families. Refer to family editing and parameters documents for more information. There are view templates for working schedule and sheet schedules. Refer to View Template documents. Working Schedules: The working schedules are intended to show all appropriate information and sort by the tag. They are intended to itemize every instance and used as the primary input schedule. Sheet Schedules: The sheet schedules are scheduling the same information as the working schedules. They do not itemize every instance and have some parameters hidden. Note: The primary think to consider is the “Electrical Data” parameter. This information must be correct for proper circuiting and can only be adjusted by changing other parameters (e_S_VOLTS, e_S_POLES, e_S_ACTUAL WATTS). Note: The Load Analysis will only function is the correct “e_S_LOAD CLASS” parameter has been correctly defined.

How to Learn

3.1

Schedules: Electrical Device Schedules

The Electrical Devices are scheduled in the “…SPECIAL EQUIPMENT SCHEDULE…” Fill out the appropriate information for each device. If it is not tagged then it will be considered General Use. You should be able to edit all the parameter information until the device has been circuited. Some parameters will have a window for selection like “e_S_LOAD CLASS”. Confirm that the schedule is properly filled out prior to circuiting and use this schedule while circuiting.

How to Learn

3.2

Schedules: Electrical Equipment Schedules

The Electrical Equipment (Disconnects and Starters) are scheduled in the “…MECHANICAL EQUIPMENT SCHEDULE…” and filtered per the “e_S_SCHEDULE KEY” parameter that has the default value of “”DISC/START”. Fill out the appropriate information for each device. You should be able to edit all the parameter information until the device has been circuited. Some parameters will have a window for selection like “e_S_LOAD CLASS”. Confirm that the schedule is properly filled out prior to circuiting and use this schedule while circuiting.

How to Learn

3.3

Schedules: Lighting Fixture Schedules

The Lighting Fixtures are scheduled in the “…LIGHTING FIXTURE SCHEDULE…” Fill out the appropriate information for each fixture. You should be able to edit all the parameter information until the fixture has been circuited. Some parameters will have a window for selection like “e_S_LOAD CLASS”. Confirm that the schedule is properly filled out prior to circuiting and use this schedule while circuiting.

How to Learn

3.4

Schedules: Lighting Devices Schedules

The Lighting Devices are scheduled in the “…LIGHTING DEVICE SCHEDULE…” This schedule is primarily only used for trouble shooting the “e_S_LOAD CLASS” parameter when the Load Analysis on the Panel Schedule has additional classifications that you are not expecting. You should be able to edit all the parameter information until the device has been circuited. Some parameters will have a window for selection like “e_S_LOAD CLASS”.

Families: Special Family Settings Specific Families will require special settings to function. e_S_BRANCH = if(CRITICAL, "C", if(LIFE_SAFETY, "LS", if(EQUIPMENT, "EQ", "N"))) This parameter is used to change the color and filter of the families during the DD phase and then used as a quality control check when circuiting in the CD phase. e_S_SCHEDULE KEY This parameter is used by the schedules to sort and filter the appropriate equipment into different schedules. Disconnect and Starter Families = DISC/START Transformer Families= XFMR Panelboard = PNL e_S_PANEL BRANCH Applies to Electrical Equipment (Panelboards, Transfromers, and Transfer Switches) e_S_PANEL BRANCH = if(CRITICAL, "CRITICAL", if(LIFE_SAFETY, "LIFE SAFETY", if(EQUIPMENT, "EQUIPMENT", "NORMAL"))) Fire Alarm Devices: This family has a visibility parameter to control the viewing of the area of coverage for the candela value. Lighting Devices: Occupancy Sensors This family has a visibility parameter to control the viewing of the area of coverage of the specific sensor.
