The engineering team at The Charles Hotel utilizes environmentally-friendly HVAC practices on a daily basis.  Recently the hotel installed variable speed drives (VFD’s) on air handling units to control static pressure, and on cooling towers to slow down the control fan motors which cool the water that is used at the hotel.  These VFD’s help to slow the drive motors by reducing electricity going to the motor, and therefore reduce the amount of consumed kilowatts. 

Four energy efficient motors were recently installed on the hotel’s chilled water and condenser water loops, which have helped to save 2,000 kwh per year.  The Director of Engineering made a strong effort to expand The Charles Hotel’s energy management system by incorporating additional equipment, utilizing compact-energy efficient light bulbs in all public spaces and adding additional employees to overnight shifts in order to shut down the equipment during off hours.

The engineering and housekeeping departments of The Charles have also implemented a green room program to conserve water and reduce phosphors from detergents being released back into the water system.  This program allows guests to choose whether their bed linens are laundered daily or every other day, therefore saving water and electricity, and eliminating pollutants as well.  And every single employee in every department of The Charles Hotel is able to do their own part for the environment by recycling paper, glass, newspaper and cardboard.
