I’m taking my first stab at trying Revit’s Heating and Cooling loads calculations.

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.

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. I’ve also transferred project information from their model to mine.

When I click a space it gives me information such as specified airflow l/s.

Then I also have Dimensions information: Area, Perimeter, Volume, Unbounded Height and Computation Height.

Anyway 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. I click calculate and get a report.

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. This report give useful information for them such as the Area and the Number of people per room.

Finally the calculations in the report are reliant on U values (I think)

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.

Thanks

**Where has this information came from?**Then I also have Dimensions information: Area, Perimeter, Volume, Unbounded Height and Computation Height.

**What is the difference of Unbounded Height & Computation Height?**Anyway 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. I click calculate and get a report.

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. This report give useful information for them such as the Area and the Number of people per room.

**But 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 4**Does 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.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?**

Aside from my questions am I missing anything or am I doing it correctly so far?
