The Cry­stal

Architect: Wilkinson Eyre/Pringle Brandon Perkins + Will

"The Cry­stal" urban deve­lop­ment centre in London sets architectural and technical stan­dards – parti­cularly in terms of sus­tainability. By deve­lo­ping solu­tions for individual require­ments using stan­dard compon­ents, Gretsch­-Unitas played a part in tur­ning this bold sta­te­ment of modern building con­struc­tion into reality.

GU exper­tise for tailor-made facade design
Our exper­tise for deve­lop­ment of cust­omised solu­tions preci­sely tailored to cust­omer require­ments in parti­cular was called upon at the building pro­ject in the Bri­tish capital. One of the challenges was to imple­ment Par­allel-Pro­je­c­ting outward ope­ning win­dows in a variety of different forms – from tra­pezoids to par­allelograms to rectan­gles – arising as a result of the cry­stalline form of the building enve­lope. All win­dows can be steplessly opened and closed by motor-driven Quattro chain drives. Further require­ments included the equipping of win­dows on the ground floor with pinch point moni­to­ring via con­tact strips. The win­dows the­re­fore meet the require­ments for finger pro­tec­tion according to pro­tec­tion class 4.

The win­dows throug­hout the whole building are equipped with our concealed hard­ware and drives which play an important role, parti­cularly in rela­tion to the cli­mate control concept and fresh air supply to the "Cry­stal". Inside the building itself, sen­sors determine the situa­tion-depen­dent ven­ti­la­tion require­ments every 30 minutes – depending on the weather condi­tions and the number of people in a room. The ven­ti­la­tion sce­na­rios rely on the natural exchange of room air. The ope­ning widths of the window are the­re­fore as much as 355 mil­li­me­tres to gua­rantee optimum exchange of air.

Cust­omer-specific advice leads to success
We worked through the speci­fica­tions and require­ments of the invi­ta­tion to tender toge­ther with the aluminium-system supplier and the fabricator, and our solu­tion imple­ments as far as pos­sible the fabrica­tion require­ments of the metalworking firm.

Quality assurance with endurance testing
To gua­rantee a seam­lessly high quality stan­dard throug­hout the entire pro­cess, an endurance test was carried out on the chosen design at the Gretsch­-Unitas test centre in the lead up to pro­duc­tion and proof of its fit­ness for use was thus obtained. In addi­tion, a pro­totype ele­ment was built at the fabricator's premises before the start of series pro­duc­tion. The result was win­dows that, despite their extremely complex forms and high equip­ment and design expecta­tions, could be manu­factured extremely eco­no­mi­cally and effici­ently installed: during the installa­tion, only the elec­tro­nics needed to be connected to the junc­tion box speci­ally pro­vided in the hard­ware zone in order to inte­g­rate the compon­ents in the building tech­no­logy system.
