Cool Roofs and Walls for Low-Cost Energy Code Compliance

Cool roofs and cool walls are a low-cost alternative to insulation for energy savings, thermal comfort and energy code compliance in Hawaii. This presentation covers energy code pathways and options for roof and wall materials that offer high solar reflectance, for lower cooling loads, improved thermal comfort and other benefits. The focus is low-rise residential and small commercial buildings. LEARNING OBJECTIVES 1. Identify a variety cool roof and cool wall material options and colors 2. Identify the energy savings potential of cool surfaces 3. Determine relevant energy code compliance options 4. Describe other benefits of cool surfaces such as thermal comfort and reduced AC load
