Abstract

Energy (EERE) under the Building Technologies Office under Award Number EE0007570.The work presented in this EERE Building America report does not represent performance of any product relative to regulated minimum efficiency requirements.The laboratory and/or field sites used for this work are not certified rating test facilities. The conditions and methods under which products were characterized for this work differ from standard rating conditions, as described.Because the methods and conditions differ, the reported results are not comparable to rated product performance and should only be used to estimate performance under the measured conditions.
