3d Plumbing Visualization

I found this extraordinary video at plumbingengineer.com a great resource. The video is a visualization of an innovative hot water recirculating system by Viega. They term it an "Internal Recirculation System" and definitely encompasses sustainability from the waste, energy and cost savings viewpoint. Check out this great 3d vid and see what I mean. It just reminded me of how important the visualization aspect of BIM is for being able to really illustrate points like these. I know that the "I" for Information in BIM is definitely the most important, but you can never deny the power of a great presentation.
