FYI.............

Based upon chilled water load demand experienced thus far this summer cooling season, the predicted heat and humidity levels will make control of tight climate control spaces for temperature and humidity across campus very challenging. Cooling demand control conservation measures will be necessary. Beginning late this morning chilled water load curtailment steps will start to be implemented. Staff will be monitoring cooling load demand closely and only implement steps as necessary to balance cooling demand to our limited cooling capacity. We anticipate cooling conservation measures to be in place all week if the weather holds as predicted. In order to reduce the demand placed on the chillers, please take additional steps such as: shutting off lights in unoccupied areas, turning off unnecessary/unused equipment and appliances (computers, coffee pots, etc.), lowering window shades on the sunny side of the building, etc. (Use of portable fans is appropriate to augment comfort where needed.) We appreciate your cooperation and patience.
