1. Natural air drawn into horizontal slots in cladding, with pressure differentials generated by aerodynamic form of building drive natural ventilation. Architects selected glass for thermal performance, safety and security reasons.

2. Productssliding hardware systems for - glass/metal construction - wood construction - furniture SwissRe’s new headquarters in London will have a double cladding. The inner façade is being realised with HAWA- hardware systems. Heavy glass panels, which appear as a flush front when closed, may be slid away. Thus enabling servicing staff access to the space between the two façades. Switzerland

3. Dupont Lmainated glass. External glass envelope acts as ecoustic buffer to outside and provides natuarl ventilation, daylight, and views. An assymetrical laminated inner panel in a sealed double glazed unit where a selective coating applied to thinner inner layer reflects reradiated heat, intercepted by blinds, away from internal ofice. Inner layer to have thermal potential.

4. 2nd highest in part of town 40 story height First tall since 1970’s due to heirage consciousness Façade opens to provide freshh air, reduce a/c Decentrallised mechanical vents

5. 1 basement parking level with bicylce spaces, showers, but no car spaces. 360 degree vies from conic shape roof top. Relatively small footprint led to unique shape. Climatroffice with enclosed glass skin and microclimate. Doubled curved geometry not sied for 1970s. Parametric modeling

6. Façade has structural grid wch frees floor plates of cross bracing. Central core is load bearing, no lat support Lightwells-light, venthilation, aptial quality Tined glass for solar radiation control., exhaust betweenpanels used fror solar raiation cushion to offs space
