Hello everyone, I am slowly learning how to use EnergyPlus through Revit. One error I can't seem to figure out is the fact that the total building area is different from the one I modeled when I get the EnergyPlus report. I am using only Revit (not downloading IDF to run in E+). I care that results are correct in Revit. I made an analytical spaces schedule, and it perfectly matches the total area of the building. Therefore, there is consistency, also because all spaces are conditioned. My building has hypothetically 100SF internal area. My analytical spaces schedule result in the same 100SF. But when I run the analysis in the report I can read as a total building area only 40SF. Despite the whole building being conditioned. Is itexplainable somehow? Now my question is, if this building does not exist how do I assess the correctness of the result? Is energy plus, through Revit, calculating the energy consumption on the 100SF of the analytical spaces or on the 40SF that I get in the results report?
Hello good time. I want to do energy analysis for one day per year in revit, how should I do it? Also, for this purpose, I want to enter the ambient temperature manually, in which part should I do it?
They are one in the same... Sort of, from autodesk: "Green Building Studio is the back end engine for Insight360. Insight360 provides a sensitivity analysis and combined factors for high performance building design. You can use insight360 to have real time interaction with the design parameters and compare the performance with benchmarks." I am sure Dan has an even better explanation.
I watched an older video (2017-2018 ish) and noticed that you could get heating and cooling loads in Insight too, however I haven't been able to find it, has that feature been removed in any recent update?
The Revit side of Insight is built-in... on the Analyze tab, in the Energy Optimization panel (these groups of commands prep a model to push out to Insight).
Great overview. My only comment towards the end is that using the term “steel framed building” when you mean “cold formed metal stud framed wall”…load bearing or not…may be confusing to some. For me “steel framed” means steel columns and beams.
I've been toying with this in RVT2023 and find the UI to be classic RVT (graphically and syntactically pretty bad). So here's my Stupid Question(s) 1) Is it correct that the "Use Conceptual Masses and Building Elements" setting recognizes element geometry but not element thermal characteristics until you go deeper and check "Detailed Elements". 2) At about 1hr, Dan talks about getting a more sophisticated measurement and does a Schematic Types override of an Exterior Wall. Then he talks about about RVT automatically derating the R-Values to account for thermal bridging. I noticed that the wall he picked was "R-13+3.8 metal frame wall" if you look to the right and divide 1 by the given U-Value, you get the R-Value of 9 that shows up in the Analytic Surface properties dialogue box. So is it correct that Dan's use of the term "derating" means "dig deeper and don't trust the naming of the wall types."? 3) When I check the "Detailed Elements" box, the R-Value of the Analytic Surfaces matches the R-Value that I see in the Edit Assembly dialogue box for the Wall Type. Is it safe to assume that The Factory has automatically derated the thermal properties of each wall layer? If not, how does one correct for that? I Thermal characteristics are often labelled as if they are a monolithic material but except for a mass timber building, one wouldn't have a solid pine wall.....in the case of a residential stud wall where one has wood studs and insulation co-existing, how would one label that layer and assign proper thermal values? What would one do in the case of an antique house with wood studs but no insulation?
I think the answers are Yes, Yes, and No. Dan give more detail on derating here. bimchapters.blogspot.com/2021/05/creating-custom-thermal-asset-for-revit.html
JEFF AND THE TEAM ARE THE BEST. I SPEAK FOR ALL OF CANADA. YES I HAVE THE ENTIRE COUNTRY BEHIND ME. CHEERS.
I love my neighbors to the north! Oh Canada!
The best explanation of energy analysis in Revit I have seen! Great demo and topic Jeff and Dan!
Thanks, Patrik... glad you liked it!
Glad you enjoyed! Thanks for tuning in!
JEFF, THANK YOU SO MUCH FOR WHAT YOU DO FOR ALL OF US. NOT SCREAMING JUST DRAFTING......HENCE CAPS.
Haha, I read all caps just like no caps these days... I get it. Cheers!
That Tip is actually awesome to use for everything!
Glad you think so!
love it! missed it live! great post, thanks for sharing!
Thanks, Thesla! Glad you liked it:)
Thanks for tuning in Thesla!
Great stuff. Thank you Jeff and Dan!
Cheers! Glad you enjoyed! Thanks for tuning in!
thank you so much..finally i understood a bit about energy analysis
Cheers! Glad you learned from it!
that was an amazing BBB tip from Beth - boss move Beth. That's huge
Yes it was! This audience is full of awesome tips! I love it!
Late to the party, but this has been super insightful and helpful! Thanks Jeff and Dan.

Excellent walkthrough. Thanks Dan! Any thoughts on comparison to cove tool?

Thanks Jeff and Dan. I have a question: what is the role of Green Building Studio (GBS) in energy analysis. How GBS interacts with Insight.
They are one in the same... Sort of, from autodesk: "Green Building Studio is the back end engine for Insight360. Insight360 provides a sensitivity analysis and combined factors for high performance building design. You can use insight360 to have real time interaction with the design parameters and compare the performance with benchmarks." I am sure Dan has an even better explanation.
@@TheRevitKid Thanks Jeff
@@TheRevitKid Right... you can even open GBS and see all of your Insight runs. But we almost never need to do that.
I watched an older video (2017-2018 ish) and noticed that you could get heating and cooling loads in Insight too, however I haven't been able to find it, has that feature been removed in any recent update?
thank you !!
Cheers !!
Is Insight another Revit plugin? Analyze tab only shows Lighting and Solar on my Revit

Sick tip
For real! Thanks for tuning in and thanks to Beth for sharing the tip!
If anyone may help me with Green Building Studio carbon emissions, as it is not showing any carbon emissions for any building type in any location.
Great overview.

Fair enough....

Great talk. The audio isn't balanced between the two of you which is a bit frustrating
What's up with that music man lol.
Its groovy. :)
