Study Reveals Importance of Dynamic Solar Shading for Window Design

A team of researchers have created a tool that reduces heat loss from windows on nZEBs. The tool is easily accessible to architects and was developed whilst the researchers were examining the different effects of static and dynamic solar shading on nZEBs

In the study, dynamic solar shadings (which, in contrast to static shadings, can be operated automatically as required) turned out to be more efficient.

We developed a calculation method for determining the portions of the façades of buildings that receive the required direct solar access in an urban environment. This allows you to determine which portion of the facade needs shading and which does not. In addition, this method can be used to determine whether to select vertical or horizontal shading.”

With regards to window models in nZEBs, the authors concluded that comprehensive window models should be chosen over simplified models.

Our study clearly illustrates the importance of different variables, such as accuracy of window models, construction costs, energy prices, interest rate and inflation. The lowest energy use was achieved with large quadruple windows and automated Venetian blinds with an advanced control algorithm."

The research project based scientists' recommendations to favor dynamic solar shadings to static ones, detailed window models to standard windows, and to engineer buildings based on the daylight factor and not the solar radiation criteria are taken into consideration in the EU construction requirements for nZEBs, which will come into effect at the end of 2020.
