A BIPV Case Study of the Environmental Effects with the PV Energy Performance

The operation of BIPV case study aimed to the environmental effects of the architectural design on landscape, which estimated the usability between human behavior and renewable energy on the design management. The BIPV project was the landmark of the local city hall, when it was built in Tainan Country in 2005, and it was the first BIPV research model in Taiwan. The multifunction covered three aspects: renewable energy usage, green site planning and underground parking lot. The BIPV working system was a hybrid system, which used 219 pieces PV modules by glass-to-glass type, and had total PV capacity of 24.09kWp. In the PV renewable energy, the DMY data was from 1.42 to 1.82 (kWh/day/kWp) and the PR value was form 36.6%-49.2%. For consideration of each evaluated factors, the architectural esthetics and energy design of the BIPV research case was not perfectly balance in the project. The citizens could accept this modern urban park as a friendly design for usage. But the PV power efficiency, the excessive design and inexact distribution decreased its power performance too much. Ultimately, the research presented an intensely interesting data for Taiwan BIPV development between the PV industry and architectural design.
