Building Green with BIM : Existing Conditions

I wondered ho much of the green movement would get sidelined due to the tanking economy, and how much acceleration LEED certified projects will continue to get.   Regardless of LEED though going green is proving to be cost effective, so effect on the bottom line are always going to get noticed.  BIM allows option analysis from an energy perspective.   You can perform solar analysis, heat gain/loss, options to replace glass with low-e, double paned, or triple paned, and run your ROI on a project by project basis.  What is the payback by re insulating  or  upgrading the power plant is much easier calculated with a BIM.  A recent article by Karl Heitman in the REournal goes on to say that you need to take into account the “embodied energy” in a building and that it would take 75 years of LEED Platinum Certified Building to repay the loss of tearing it down.  So need to refit and reuse, create great projects with your existing conditions.

How you can capture existing conditions in a BIM format?  So far, not so easy.
