Smaragden is an impressing fully glazed space serving as a meeting point in the courtyard of Brännaren 18. This project is part of the renovation plan for the industrial area of the Sorgenfri neighborhood in Malmö. The idea is to create a mixed-use area with focus on residential buildings.

Our contribution to the project was to inform the fully glazed facade design (skylights and vertical façades) of Smaragden in order to provide an all-year-round inviting space for the visitors.

Natural ventilation

Part of our contribution was to effectively introduce natural ventilation and ensure indoor air and operative temperatures lower than the set targets. Openable dampers in the vertical facade and the skylights were required. Our scope was to advise on the position and size of the openings.

As the effect of natural ventilation is highly dependent on the outdoor air temperatures, it is inevitable that occasionally the space might overheat (warm, sunny days). Our goal was to provide an indoor environment that is always welcoming; cooler than outdoors in summer and warmer than outdoors in winter.

Design solution

By applying frit in selected areas of the vertical façades and the skylight, we provided a facade solution which is in line with the architectural intent and provides adequate solar protection.

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 frit for each glazing unit.
