Energy Efficient Building Technology: Multi-Function Facade Systems and a New Approach to Using Photovoltaics

RPI ID: 2003-022-201

Innovation Summary:
This invention introduces a hybrid solar collection and daylighting system that integrates into glazed building envelopes—such as windows, curtain walls, or skylights. The system uses non-imaging optical elements to concentrate and redirect sunlight for two simultaneous purposes: generating solar power and delivering natural daylight into interior spaces. A key feature is its ability to dynamically track the sun and separate visible light from infrared, optimizing both energy harvesting and indoor lighting quality. The design is modular and scalable, making it suitable for both new construction and retrofitting of existing buildings.

Challenges / Opportunities:
Traditional solar panels and daylighting systems often compete for the same building surface area and lack integration. This invention addresses that limitation by combining both functions into a single architectural element. It opens opportunities in sustainable building design, where maximizing energy efficiency and occupant comfort are top priorities. The system also supports net-zero energy goals and LEED certification efforts.

Key Benefits / Advantages:
✔ Dual-function system for solar energy generation and daylighting
✔ Integrates seamlessly into building façades and glazing systems
✔ Enhances indoor lighting quality while reducing HVAC loads
✔ Supports sustainable architecture and energy-efficient design

Applications:
• Green building and sustainable architecture
• Commercial and institutional building retrofits
• Net-zero energy construction
• Smart façade and daylighting systems
