ASHRAE Issues Grant for Interoperability: #BIM

ASHRAE, the American Society for Heating, Refrigeration and Air Conditioning Engineers just issued a grant to Texas A&M for “ensuring that a common language of ‘energy efficiency’ is spoken by the both building information modeling software used by architects and energy analysis and simulation software”.  I have not played around with Ecotect or IES enough, but I know it had required separate 3D modeling outside of  standard BIM authoring software, getting to a point of seamless data exchange you would think would be a starting point not the end point, but glad we are moving that way.

This is the title of a recent article in the Boston Business Journal.  “Once the money starts to flow, architects will be busiest retrofitting existing buildings to meet current environmental building codes and industry standards for energy efficieny, as cost effective alternatives to building from scartch,” said Nancy Jenner director of the Boston Society of Architects.

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.
