The architect should be inputting U-values into their model, but I wouldn't count on it. "Finally the calculations in the report are reliant on U values (I think ) so does the architect input this info into his model and my report picks up on this?" If there is no ceiling in the room, the space will continue until it finds another room-bounding object, usually the floor above or the roof. The ceilings in the linked model should be set to room-bounding. The space will stop at a room-bounding object. "Does the area information stop at ceiling level or is this from floor to slab? " If you look at the properties of the space and click on "People", you'll see that you can leave it at default or you can change it to a specified value. The number of people per room/space is determined by your space type settings, or it can be specified per room. "But where has the number of people information came from?" You shouldn't have to worry about this unless you have a sloped wall in your room. Computation height is used to compute the perimeter and area of a room. The actual height of the space will be determined by a room-bounding element like a ceiling though. It's supposed to display the "largest potential height of the room based on room height parameters". Unbounded height is kind of a strange one. What is the difference of Unbounded Height & Computation Height?" "Then I also have Dimensions information: Area, Perimeter, Volume, Unbounded Height and Computation Height. Actual airflow comes directly from the air terminals placed in the space. Specified airflow is just a number you can type in. "When I click a space it gives me information such as specified airflow l/s. We've had marginally better success exporting the gbxml info from Revit into Trane Trace, but the space information can still be inaccurate. We have not been able to get accurate heating and cooling loads directly from Revit no matter what we try. I appreciate there is a lot of questions here and I don't expect someone to know the lot but hopefully anyone with a bit of experience using this part of Revit can answer what they know and I can go from there. This report give useful information for them such as the Area and the Number of people per room.īut where has the number of people information came from? This is confusing me because the Architect’s called his room Changing Room - 15 Person but the info on my report says Number of people 4ĭoes the area information stop at ceiling level or is this from floor to slab? Our engineers only require the area between the floor and ceiling for their calculations so I need to clarify this.įinally the calculations in the report are reliant on U values (I think ) so does the architect input this info into his model and my report picks up on this?Īside from my questions am I missing anything or am I doing it correctly so far? The report gives me a ton of information which I don’t know if it’s correct or not, but I can now pass this report to our Design Engineers. What is the difference of Unbounded Height & Computation Height?Īnyway this is what I have so far and I want to run a Heating & Cooling Calculation so once I’ve hit the button I get window With Building Type, Location, etc. Then I also have Dimensions information: Area, Perimeter, Volume, Unbounded Height and Computation Height. When I click a space it gives me information such as specified airflow l/s. I’ve also transferred project information from their model to mine. What I have so far is a linked Architects model and I’ve added my spaces and used the space naming utility add in to name them according to their room names. We actually have a book in the office that includes this briefly but someone has taken it home so i’m trying to get by the best I can for the minute. I’m taking my first stab at trying Revit’s Heating and Cooling loads calculations.
