BIM is promoted and marketed by all factions of the design and construction industry as being THE critical component to successful project delivery with promises of streamlined cost and schedule metrics and efficiencies galore. More projects and owners require BIM now than ever before. This session brings together three industry experts to provide ASHRAE members with practical guidance on strategies to successfully implement BIM-based workflow for MEP design and building energy modeling.

This session addresses the challenges of high ambient countries in finding alternatives for the widely used HCFC-22 in residential air-conditioning applications. A project was launched to test locally built prototypes running with different low-GWP alternatives. The session discusses the outcome of these tests and a comparison of the results, which by no means endorse any of the tested refrigerants, but shed light on possibly workable refrigerant alternatives for high ambient operation. Other aspects of the project dealing with economics, technology transfer and the challenges of implementation are introduced, including recommendations of further required investigation.
