I recently returned from the ASHRAE Annual Convention in Dallas (#ASHRAE, #Dallas2013). For me, ASHRAE conventions make it easy to keep up with new developments and new ideas in heating, cooling, ventilation, filtration, Standards and more. Since HVAC can amount to more than 70% of a building’s energy use, and I am an energy efficiency consultant, I need to stay on top of new ideas, codes, Standards and best practices.
