Very interesting test with the Solar Radiation Technology Preview plug-in for Revit 2011: “There’s been a Solar Radiation “Technology Preview” plug-in for Revit available up on Autodesk Labs for a while now. I’ve been curious about it, but haven’t had an idea to apply to it till now. So I mixed up a little form study of Foster and Partners’ London City Hall to give it a test spin. Foster’s design is a nice test case as the building form is directly driven by some relatively simple principles about passive solar design. In a temperate zone, maximize winter solar gain and minimize peak summer sun exposure. Through some clever geometric arrangements, the south face shades itself in the summer, and is basically fully exposed in the winter.”

Recently made available on Autodesk Labs, the Solar Radiation Technology Preview for Revit 2011 delivers an integrated and visual analysis experience.
This updated preview takes full advantage of some new functionality in Revit 2011, for example use of the new Analysis Visualization Framework API is shown off here for the first time (The Analysis Visualization Framework is a mechanism for an analysis application to easily display computation results as transient 3D data in the Revit model).
The Solar Radiation Technology Preview for Revit 2011 allows you to understand and quantify solar radiation on various surfaces of your building information model.
There is even a new discussion forum specifically for the Solar Radiation Technology Preview for Revit.
Based on the concepts known from Ecotect Autodesk Revit Architecture 2011 enables you to simulate the sun path, in order to better understand the impact of the sun in relation to your project and its surrounding context. The sun path is a visual representation of the sun’s range of movement across the sky at the geographic location you specify for a project. The sun path displays in the context of your project and includes on-screen controls for positioning the sun at any point within its range of movement.
Along with this you can set the sun settings where changes have been made to how you select your project location. Included in the location dialog is a Google Map interface where you can search for your exact location.
Please check the website below for information on a two day seminar on BIM and Sustainability to be held on the Illinois Institute of Technology (IIT) Chicago Campus, College of Architecture Computer Laboratory from Thursday March 11 to Friday March 12.
This is an exciting though expected development that the technology behind Ecotect will eventually be integrated right into Autdesk’s core BIM application Revit. Let’s hope this is the first of many integrated building performance tools.
Use this Solar Radiation Technology Preview to analyze the effects of solar radiation on various surfaces of your conceptual building model. The add-in uses conceptual massing elements from Revit models and the Autodesk Ecotect insolation analysis engine to calculate the amount of solar radiation hitting the surfaces of the massing shapes. This add-in works with Revit Architecture 2010 Update Release 1 and Revit MEP 2010 Update Release 1.
Go to Autodesk Labs to download the add-in. The archive includes a PDF “getting started” guide.
See this video for an overview.
SunTools, a new Plugin for SketchUp is available now.
- SunPATH: visualization (month and year)
- SunPOS: Sun Position for a date and time
- SunVIEW: Axonometric views from the Sun
- SunPENETRATION: Analyze Sun Penetration/Access in any specific analysis point.
Several features are work in progress or yet to be implemented. I think this is a very promising visulisation tool that helps understand local climate conditions (and is also a similar way Ecotect presents this info)
The plug-in can be downloaded after registration from: http://tx.technion.ac.il/~arrguedi/SunTools/download.html
Ted Ngai has posted many interesting RhinoScript and Grasshopper examples on his blog atelier nGai. Especially worth mentioning are two tutorials that experiment with a generative approach using Ecotect solar simulation data to drive the creation of geometry in Rhino. In this instance solar access data was used to determine the size of skylights in a roof based on their orientation.
The most appropriate workflow for early analysis is to begin designing within the BIM application. At this stage you can utilize the geometry for massing and orientation analysis, while also setting up thermal zones to began the process of energy modeling. But perhaps most crucial to this process is the guarantee that your model always contains the latest information, so that any change to the design can instantly be evaluated …
Autodesk Ecotect Solar Analysis data can be imported into ParaCloud Modeler and converted as solar numeric matrix. The matrix data can be used as a population matrix or as driving parameters values.
On the ParaCloud Community Blog you can find a tutorial that covers the following subjects:
- Importing surface from ParaCloud into Ecotect
- Exporting Ecotect solar calculation data as text file
- Using Excel indexing equation to match the ParaCloud format
- Rescaling solar matrix in ParaCloud as Cellular component matrix
Once you have drawn a projected solar array on top of the satellite imagery from Google Maps you get a rough estimate on performance and payback of your system based on the drawn area of the array, slope of the roof, location and weather information from the National Renewable Energy Labs.
To complete the full financial analysis your project should be in California as for now utility rate information is only available there (other states will be added soon).
