Hello!
Is it possible to run an energy analysis in Revit without considering the Air Conditioning System for the cooling load? I think it is possible, because there are a lot of places where It is ridiculous to install Air conditioning System in the summer.
Are the results Site Energy or Source Energy?
Revit Energy Analysis using Insight includes several possible scenarios of heating and cooling systems. For the baseline energy model creation, you can specify a generic HVAC system, even if you plan to use no cooling system. In order to model a building with no cooling system, you may want to consider setting the zone set point temperatures such that no cooling energy is used. It is possible to evaluate the impact of HVAC system using the Insight factor widget.
Revit/Insight energy analysis results are presented using site energy.
Could you explain me how can I no using the cooling system please?
I thought Revit/Insight results are presented using source energy, where can I found this issue?
As Krishnan pointed out in his earlier post, the Revit/Insight energy results are for site energy, not source energy. Unfortunately, we do not have this information documented.
The simulation engine used by Insight (DOE2) requires at least one HVAC system per zone, which means there will need to be an HVAC system in your model or the energy simulation will fail. However, as Krishnan mentioned, you can emulate a project without an HVAC system by setting the zone set point temperatures (very high temperature for Cooling and very low temperature for Heating). The temperature set points are in the Revit HVAC Zone properties. By doing so the HVAC system will never be activated and therefore the energy simulation will have no heating or cooling energy. It doesn’t matter what type of HVAC system you choose for the analysis, as long as you edit the temperature set points. For the custom set points to be used by Insight, in the Insight Energy Settings>Advanced Energy Settings>Room/Space Data choose the Export Category "Spaces."
Let us know if you have more questions on this topic, otherwise please accept as a solution so that others can benefit from this information.

Thanks @mstein7484 for the your answer,
but I did the following steps:
1- Create a space in each room
2- Define HVAC zone
3- Properties - Energy Analysis - Condition Type - Heated( picture is attached).
4- Run Energy Simulation
The results with only heated condition type are higher in terms of energy use intensity than with Heated and Cooling one condition type. In theory it's impossible!
But if I click in Heating and Cooling Loads (Analyze - Reports & Schedules) appear 0 cooling load as is obvious that it is!
Have you a solution for my issue?
Thanks in advanced
Hi, I have problem with my Energy analysis. Has anyone problem like this?

Hi @Anonymous
Could you export the files from Insight for the "Heated" as well as the "Heated and Cooled" Insights & send them to me in a private message: (see the screenshots)
1. Open the Insight where the models are
2. Expand the menu for the models and select "Export"
3. From the file options, export all of the files
4. Make sure to label the exported files clearly
Regards,

I am facing the same problem here. I don´t want any cooling system. I have defined the zones as heated too but what´s the correct way to solve this problem? Should I keep the temperature set point very high temperature for Cooling and very low temperature for Heating?
I only have eletrical radiators in my building.
