A new angle-selective see through building integrated photovoltaic facade is presented here. The facade combines four important tasks in one element: solar control, glare protection, visual contact and electricity generation. Mathematical analysis and simulations with radiance are performed to optimize the geometry and to assess the visual transmission of the new window. In order to simulate the new facade in building energy simulation programme a new method for modelling the total solar energy transmittance is presented. The new black-box-model (BBM) is implemented into ESP-r software and is validated. The BBM is used to assess the impact of modelling accurately the g-value of complex facade within building simulation.
