Movable window insulation as an instantiation of the adaptive building envelope: An investigation of its cost-effectiveness in the U.S

Improving the performance of building envelope is essential to energy conservation and emission reduction. Adaptive (ABE) has potential effectively reduce consumption at a lower cost. Movable window insulation an instantiation ABE with great application in buildings, but it not been systematically studied. Trying fill this gap, paper proposes automatic control system manual rule for movable insulation. The double-glazed windows, triple-glazed automatic/manual control, electrochromic windows compared different scenarios using simulation (BES). In some scenarios, optimal solar heat gain coefficient (SHGC) higher than that required by code. Triple-glazed are only effective reducing heating energy, while cooling energy. Infiltration impact on net preset value (NPV) analysis shows Minneapolis, Atlanta, Phoenix, viable cases Minneapolis. Electrochromic profitable investment their current prices.
