Light colored roofs, known as cool roofs, have gained popularity as a strategy to reduce cooling energy use for both residential and commercial buildings. While static cool roofs (SCRs) with constant optical properties are effective in reducing cooling thermal loads, they can increase energy use due to heating. A solution to avoiding significant heating energy penalties is the adoption of dynamic cool roofs (DCRs) with variable reflective coatings. This chapter explores the potential energy savings of DCRs with seasonally variable reflective surfaces for various building prototypes when compared a static cool roofs. The analysis demonstrates that any additional energy savings...
