Abstract
Energy efficient building design is becoming increasingly important as energy costs continue to escalate. In addition, energy efficiency is one of the primary building blocks for sustainable and green building design. This paper will summarize research programs that have been sponsored by SPRI and conducted at Oak Ridge National Lab. These programs covered: 1) the use of reflective single-ply membranes and their value in energy-efficient roof design. This research discusses the long-term impact of using hight reflective roof membranes and the importance of both reflectivity and emissivity. It also discusses geographic locations where the benefits of these membranes are maximized. 2) the energy-efficient benefits of ballasted single-ply roof systems. In this study, the long-term savings benefits of both stone-ballasted and paver-ballasted single-ply roofing systems are summarized. 3) the energy savings benefits of these systems are comparted with each other, and the benefit of using thermal insulation in conjunction with these systems is provided.
