Lyeffion Elemetary School’s classroom #12 received an application of ThermaCote ceramic coating, and an adjacent classroom #11 was left uncoated. Meter readings were recorded on three separate occasions in both classrooms. Power usage in the last period of approx 22.5 hours revealed a 40% KWH usage reduction in the coated room.
Latest readings show the ThermaCote classroom at 129 KWH, and the uncoated classroom at 202 KWH. This calculates into a 36.1% reduction in electricity usage for the air conditioner in the coated room as opposed to the usage in the control room. It bears noting that this facility already had a light colored roof coating. Application of this material to dark roofs or the underside of roof decking with dark shingles would produce even more dramatic results. In addition, ThermaCote has a .83 solar reflectivity as established by the Cool Roof Rating Counsel. This high radiant reflectance can result in reduction in the number of fluorescent tubes needed to deliver an appropriate amount of light to the desktops, which could conceivably increase savings on the lighting portion of the power bill.
