Smaragden

The pavilion is intended to be used as a social space throughout the whole year and create a comfortable environment that would allow the users to be connected with the courtyard, while being protected from any undesired environmental conditions outdoors.

Our Clients involved us in an early stage to advise them on proper solar control mechanisms that will allow for a fully glazed envelope with minimum overheating risk, daylight of high quality, good views out and a feasible, low-maintenance design.

 

As the fully glazed pavilion will not be evenly exposed to solar radiation throughout the year, we took the initiative to investigate the option of applying "tailored" solar control at the skylight, prioritizing the solar control intensity in the areas based on their use. The selected solar control mechanism (frit) is angle-independent, unevenly distributed, and constantly performing, applied to specific areas of the skylight and vertical façade.

Frit as a solar control mechanism

​

Frit was examined as a solar control option. The assessment of the required frit on each glazing unit was based on a spatial analysis of the (Corrected) Operative Temperature.

To properly distribute the frit in the glazing units, we predicted the overheating hours for several occupant positions accounting for the effect of Direct Solar Component; then, for each overheating hour, we ray-traced the sun positions and marked the intersection points on the building’s envelope. By further processing the output data, we calculated the required percentage and placement of the frit for each glazing unit.
