Concept: BIPV as design catalyst for a high-rise building. Optimization: Balancing BIPV and Human comfort. Integration: Incorporating BIPV into a custom curtain wall design.
Concept: BIPV as design catalyst for a high-rise building. - Site Constrains: Building Orientation and the contextual relationship to the predominantly orthogonal architecture of the Yeoido district of Seoul . - Power generation requirements: The cities requirement that all new large scale commercial buildings generated a minimum of 5% of its energy on site. - Incentives: FIT provided by local electric utility company (KEPCO)

New/Renewable Energy Generation Requirements Select systems that are certified as New/Renewable Energy by National accreditation organizations and apply those that are most practical and realistic for the building in terms of cost, constructability, and maintenance. systems that may apply:
Geothermal, Solar, Wind, Fuel-cell, Hydro. - New/Renewable Energy should follow the chart below for allotment, and should have capacity to meet all items (construction cost, peak level, and total energy use).

Optimization: Balancing BIPV and Human comfort. - Multitasking: Glare Reduction, Shading and Power Generation. - Balance between the performance of the BIPV and Human comfort. - Architectural Expression.
The search for balance between the performance of the BIPV and Human comfort became a function of the relationship between the angle of the vision glass and the spandrel panel.
