Spending Millions To Fix 'Walkie Talkie' Glaring Error

Fix for 'Walkie Talkie' skyscraper will cost millions, developers say.

Two developers say they will spend several million dollars on the facade of London’s 37-floor “Walkie Talkie” skyscraper to prevent the solar glare that caused scorching damage in the adjacent street last summer (ENR 9/16/13 p. 20).

Lightweight, 38-centimeter-long metal fins, or brise soleile, will be fixed to the curved south facade of the building at 20 Fenchurch St. in a six-month operation, subject to planning approval from the local authority. Eight levels of fins are planned for each floor, from No. 3 to No. 34.

Solar-glare investigations ordered by the joint developers, Land Securities Group plc. and Canary Wharf Group plc., both based in London, identified the concave curvature of the south elevation as a key cause of the glare.

The “almost perfect curvature of the facade” and high levels of reflected energy also contributed, the investigators reported. Crews hung a curtain over much of the south elevation as a temporary screen.

The building’s lead architect, New York City-based Rafael Viñoly, developed the solar-screening design with the assistance of Loisos + Ubbelohde Associates Inc., San Francisco, and Gordon Ingram Associates, London.
