The thermal performance of replacement windows has made considerable progress in a short time frame. Few studies have been carried out with regard to application of new and retrofit windows to pre-retrofit windows. The goal for this energy retrofit is occupant comfort, as 80% of a buildings energy use goes toward maintaining this standard.Any effort to make this load more efficient is worth investing and warrant post occupancy evaluation to make more informed decisions about future investments. This study gives great insight into the potentials, positives and negatives for utilization and employment of data loggers with thermal couples, infrared thermography, and tools to spot measure temperature. The paper highlighting the potentials of these non-invasive tools attentive to areas of required information the tools cannot produce in order to have comprehensive results. While these programs are not perfect, they offer valuable information with regard to life cycle costing and potential unforeseen problems.
