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).

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.
