Changing Opening Size - Dynamo

 The purpose is to study a façade design that is sustainable and helps to make the earth greener.

The goal is to study the façade design which changes depending on the time of the day.

The objective is to create a façade that has windows whose size changes reflecting the Sun orientation. To be specific, the height and width of the windows in the façade change reflecting the passage of time. At midnight and noon, the size of the window is the smallest to prevent energy loss from heating or cooling.

This study will use a façade that has 5 openings in total: 2 180 X 180 openings in the top row and 3 108 X108 openings in the bottom row.

The openings vary in their opening sizes according to the Sun altitudes.

Dynamo programming

Dimensions of openings are created as parameters, and these are designed to change according to the sun's altitude.

For the value in the ElementSetParameterByName node, SunSettings.Current node and SetSettings.Altitude node are used.

Here are the design outcomes

Opening sizes change; during the time when Sun's altitude is low (daylight is small delivering less energy), the opening size is larger than when Sun's altitude is high (daylight is large delivering more energy).
