Hi i was just wondering if revit MEP 2013 has got a lighting calculation and heating and cooling calculation system.
we are currently using Dialux for our lighting calculations and camel for our heating and cooling calcutions and autocad for our drafting.
I am trying to seal the deal so to say with my management to change over to revit mep as we are slowly getting pushed towards the product but the quicker we change the more experience we will have in it when we need it and telling them that we dont need to use dialux or camel for our calculations would help seal the deal.
would anyone know my answer.
1. does revit mep have a lighting calculator
2. does revit mep have a heating and cooling caculator
is so please share either the location of some useful information or anythign you know of would be helpful
Yes and yes. However...
Revit only does average estimated illumination levels, not point-by-point calculations. There is an add-on by Elum Tools that can do point by point but we haven't tested it much.
The heating and cooling analysis tool is quite finicky too. Your architectural model and your MEP spaces have to be created accurately in order for revit to perform calculations correctly. We have run side-by-side calculations from Revit and Elite HVAC calc software, and we can't get Revit to match the results. I'm sure with more testing we can get Revit to behave. Maybe.
so your saying that yes it does but the area tags have to be set up properly to calculate the average lumins in the area.
this addon your talking about do i have to either subscribe or pay for it or is it freeware for anyone that has revit mep
The average estimated illumination parameter for the space comes from the lighting fixture families that are placed in the space. (See attachment)
Elum tools is not free, it's about $550 for the software, and a $350 annual license. You can download a free 30 day trial here:
so the picture you attached is of elumtools or standard revit?
this can be useful for rough calculations im guessing?
would you be able to put in a parameter that would calculate the nominal illumination value of the area so you would be able to compare and would this point out dark spots so the illuminance doesnt just cover one small area and leave a large dark spot on the drawing?
Picture is of standard Revit. I don't think there's any way to force Revit to see any dark spots in a room because it's taking an average - that's what Elum tools attempts to do.
so in short revit doesnt have the capabilities as dialux as in the dark spots (illuminance levels) but with elum tools it will do this.
have you compared dialux with elum tools and what are your thoughts on each?
what are the pros and cons of them both
