## Energy Analysis with Insight
With a **FormIt Pro** subscription through the [AEC Collection](https://www.autodesk.com/collections/architecture-engineering-construction/overview), you have access to Energy Analysis with **Insight:**
* Analyze early-stage design models with Green Building Studio's analysis engine
* Connect to a dashboard view of the analysis results to compare options for your design
* Adjust the Energy Analysis factor widgets, such as Window to Wall Ratio, Building Orientation, and others
* Summarize your building's energy impact with a single number calculated as a bottom-line cost per area
* Save your Energy Analysis results for future review with clients and other stakeholders
## What's New With FormIt + Insight
### **Improvements to Insight Reliability**
* [FormIt 2021](https://formit.autodesk.com/blog/post/introducing-formit-2021) now checks your model for common model issues before launching Insight runs, and fixes common Insight failures for a more reliable experience.
* FormIt 2021 also generally improves reliability of the FormIt + Insight connection, addressing many known failures and improving run success rates.
## Getting Started
### **How It Works**
* Insight Energy Analysis uploads your FormIt model data, and runs several hundred analyses in the cloud to determine various energy scores
* Energy Analysis uses Revit to analyze your model, so just like when sending FormIt data to Revit, you'll need to [ensure your FormIt model is watertight and manifold](https://formit.autodesk.com/blog/post/repairing-solid-models)
### **Preparing Your FormIt Model**
* Insight will use any visible geometry in your FormIt sketch
* Ensure the building shell you want to analyze is the only visible geometry
* Put supporting geometry like entourage, furniture, and site elements on a separate [Layer](/tool-library/layers.md), and turn the Layer off
* Insight works best with a simple, solid building model
* Ensure your building mass is [solid and watertight](https://formit.autodesk.com/blog/post/repairing-solid-models)
* If your building design already has openings for windows and doors, it's best to create a new mass with no openings specifically for Energy Analysis, and hide the more detailed version using Layers
* The simple building mass needs to have [Levels](/tool-library/levels-and-area.md) applied
* The FormIt model needs to have a [Location](/tool-library/setting-location.md) set
### **Starting Energy Analysis**
* Look for the Energy Analysis button in the toolbar
* Click "Generate Insight" to start the process
* This will upload the visible model data, and will run several hundred simulations in the cloud
* When complete, a message will appear at the top of the screen, and the menu will update to indicate a new Insight is ready to view
* Click "View Insight" to view the analysis in your web browser
* You can also find all your Insights at [Autodesk Insight](https://gbs.autodesk.com/OneEnergy/Insight).
## Troubleshooting
### **Common Errors**
* "Insight project could not be created. Please try again later."
* Log in to the [Green Building Studio dashboard](https://gbs.autodesk.com/GBS/Project), then restart FormIt
* If you're not able to log in, or if you see an "access denied" page, you may need to [purchase a subscription to Green Building Studio](https://knowledge.autodesk.com/search-result/caas/CloudHelp/cloudhelp/ENU/BPA-Help/files/GUID-7FCFF904-F943-4020-BF7F-53AA7148673D-htm.html)
* Check that your model is [solid and watertight](https://formit.autodesk.com/blog/post/repairing-solid-models)
* Check for any issues with FormIt services on the [Autodesk Health Dashboard](https://health.autodesk.com/)
* To see if Green Building Studio successfully executed Energy Analysis runs for this project, take a look at the [Green Building Studio dashboard](https://gbs.autodesk.com/GBS/Project)
* Your latest project should appear at the top of the list, and should display 248 runs
* If it displays 0 runs, [let us know on the FormIt forums](https://forums.autodesk.com/t5/formit-forum/bd-p/142), and we can help troubleshoot further
### **Detailed Logs**
* FormIt Web provides additional details when Energy Analysis fails:
* Go to [FormIt Web](https://formit.autodesk.com/app)
* Open the model that's having issues with Energy Analysis
* Run Energy Analysis
* Open Developer Tools (hit F12 in either Google Chrome or Firefox)
* Look at the Console tab
* Copy or screenshot any errors, and [report them on the FormIt forums](https://forums.autodesk.com/t5/formit-forum/bd-p/142)
## Solar Analysis
With a **FormIt Pro** subscription through the [AEC Collection](https://www.autodesk.com/collections/architecture-engineering-construction/overview), you can visualize the sun's impact on your building:
* Specify relevant faces to be analyzed for solar impact
* Visualize results in seconds within the app canvas
* Hover your mouse over an input point to see specific calculated values of solar impact
* Choose to view results as a monthly glazing study, or as a yearly solar panel feasibility study
