High-Performance Integrated Window and FaƧade Solutions for California
The researchers developed a new generation of high-performance faƧade systems and supporting design and management tools to support industry in meeting Californiaās greenhouse gas reduction targets, reduce energy consumption, and enable an adaptable response to minimize real-time demands on the electricity grid. The project resulted in five outcomes: (1) The research team developed an R-5, 1-inch thick, triplepane, insulating glass unit with a novel low-conductance aluminum frame. This technology can help significantly reduce residential cooling and heating loads, particularly during the evening. (2) The team developed a prototype of a windowintegrated local ventilation and energy recovery device that provides clean, dry fresh air through the faƧade with minimal energy requirements. (3) A daylight-redirecting louver system was prototyped to redirect sunlight 15ā40 feet from the window. Simulations estimated that lighting energy use could be reduced by 35ā54 percent without glare. (4) A control system incorporating physics-based equations and a mathematical solver was prototyped and field tested to demonstrate feasibility. Simulations estimated that total electricity costs could be reduced by 9-28 percent on sunny summer days through adaptive control of operable shading and daylighting components and the thermostat compared to state-of-the-art automatic faƧade controls in commercial building perimeter zones. (5) Supporting models and tools needed by industry for technology R&D and market transformation activities were validated. Attaining Californiaās clean energy goals require making a fundamental shift from todayās ad-hoc assemblages of static components to turnkey, intelligent, responsive, integrated building faƧade systems. These systems offered significant reductions in energy use, peak demand, and operating cost in California
