Paul Ehrlich, P.E. has been pushing the edges of the controls industry for two decades. In the last couple of years, he has founded Building Intelligence Group (www.buildingintelligencegroup.com), received a Buildy Vision Award for his ongoing work, and joined the ES advisory board. Ehrlich is also the co-chair of the oBIX committee and is a past chairman of the ASHRAE Guideline 13 committee on how to specify DDC controls. Consulting engineers and owners interested in the benefits of intelligent buildings can attend a seminar on the Building Intelligence Tour (www.buildingintelligencetour.com) in various cities in the coming months.
