Hyperion solar adaptive shading

Example: Solar variance typical of median latitudes (Example: New York City, U.S.A.). Locations at higher latitudes such as Montreal, Canada exhibit an even greater distance between winter and summer solstices. Lower latitude locations such as Houston, Texas, have a smaller differential between winter and summer.

Seasonal solar variation

The position of the earth relative to the sun changes throughout the year. Consequently, the sun will be in a different position at noon on June 21st than it is at noon on December 21st.

HyperionTM effectively manages daylight entering the space by incrementally changing the shade adjustment schedule of each façade on a daily basis, maximizing comfort and productivity.

Advanced daylight management:

The sun’s movement is predictable. Open loop solar tracking builds a model that maps the sun’s position through each moment of the day, throughout the changing seasons.

Open loop solar tracking does not search for the sun, but instead, knowledge of the sun’s position is obtained using a set of astronomical equations.

By calculating the sun’s exact position, a schedule can effectively manage shade positions on each façade throughout the day, every day of the year. This prevents heat and glare from entering a workspace while maximizing effective daylight.
