High-Performance Integrated Window and Facade Solutions for California Buildings
High-Performance, Integrated Window and Façade Solutions for California Buildings
Project completed in March 2019. This project advanced knowledge and technologies in five areas: highly insulating windows; energy recovery-based façade ventilation systems (low-energy air flow through the façade); daylight redirecting systems (sunlight from windows reflected deep into the building); daylighting and shading optimization methods (daylight and solar heat gain models for simulating light-scattering shading and daylighting technologies); and integrated window and facades through advanced controls. Since these technologies are early prototypes, the team is continuing to pursue commercial development partners. The California Partnership for Advanced Windows was also formed to identify and overcome market barriers to facilitate market transformation toward highly insulating windows.
This project develops, validates and quantifies energy impacts of a new generation of high performance building envelope systems such as highly insulating windows, novel window-integrated local ventilation, and dynamic daylight-redirection. It will provide design and management toolkits that will enable the building industry to meet challenging energy performance goals leading to zero net energy buildings. This project considers cost-effective integrated system approaches to reduce energy use associated with HVAC and lighting while improving occupant comfort.
These technologies are estimated to be capable of reducing statewide energy use by 6,118 gigawatt-hours, peak electricity demand by 2,250 megawatts, and statewide electricity costs by $867 million/year assuming 75 percent market penetration in new and existing commercial buildings.
