Abstract
Today, garden roofs are in the industry press frequently as they exemplify sustainable roofing construction. There has been research performed in Canada that suggest that garden roofs, although exhibiting certain desirable features, do not really save energy in cold climates. The US has a wide variety of climates, ranging from subtropical to arctic. It would be valuable to know if this roofing technology has any energy savings potential in other climate zones. SPRI, in conjunction with Oak Ridge National Laboratory, has designed an experiment to evaluate the energy performance of garden roofs in the mixed climate of east Tennessee and to use this experimental data to develop and validate a computer simulation tool so that estimates of energy efficiency for this roof technology could be developed for other climate zones. This paper presents a progress report on this project.
