IntellAdjust ™ Systems A Revolution in Comfort Control

Temperature matters substantially more towards an occupant’s overall rating of comfort than any other single environmental variable, and that conditions that are either too hot, cold, or humid have the greatest negative effect on occupant productivity Occupant Comfort, Productivity, and Personal Control in Twenty Air Conditioned Office Buildings Jared Langevin, Jin Wen, Sean Hsieh, Davor Novosel, and Michael S. Waring 06/2011; In proceeding of: Indoor Air 2011 Research on Occupant Comfort………..

Thermal Comfort — A Key to Occupant Satisfaction and Productivity Mike Opitz PE, LEED AP, Certification Manager, LEED for Existing Buildings, U.S. Green Building Council If there's one thing facility managers agree on across the board, it's probably that occupant comfort complaints are their biggest routine operational headache. Keeping your occupants more comfortable will have the obvious benefit of reducing trouble calls, and therefore O&M costs. More subtle are the other benefits that can accrue: higher workforce productivity, better health, and in some cases lower HVAC energy costs. Real Life Experience……...

5 2. Central forced air systems use more energy than required. The Problem: Single thermostat systems are ineffective and inefficient They do not account for where or when energy is required  Energy is wasted on unoccupied rooms  The rooms in this representative building are empty 54% of the day  Over cooling occurs because of imperfect system design and balancing
