Location: Riga, Latvia
Area: 30 000 sqm.
Architect: Helmut Jahn
This is one of the first and biggest 30-storey twin tower high-rise residential complex in Latvia and in Europe. The towers are close to one another and are joined by a podium in the base area.
The Z-Towers complex is a combination of two absolutely incompatible things. On the one hand, apartament’s owners can enjoy a view over historical center of Riga, but on another hand - comfort and quiet life in the countryside.
The design of the facades and the exterior design of the Z-Towers was done by world-famous architect Helmut Jahn.
The composition of glazing is sophisticated due to a 400mm step to one vertical side that was used to create a facetted façade. The stepped edge of one insulated glass unit overlaps with next pane close to it and creates an effect of scales. The connecting bridge has a glass floor IGU’s with anti-slip silk-printed pattern.
In order to recommend to the Client the optimal construction of insulated glass unit, GLASSBEL R&D Department made calculations taking into account wind loads and climate stresses using a special glass engineering software, MEPLA. Due to the complicated stepped shape of the glass, a bespoke mathematical model for calculations was developed specifically for this project.
