Torre Iberdrola honored for LEED Platinum by U.S. Green Building Council

NEW HAVEN, Conn. (Feb. 28, 2013) — Pelli Clarke Pelli Architects received official recognition Thursday for the environmentally sustainable design of Torre Iberdrola. In a presentation at its offices in Washington, D.C., Judith E. Webb, Senior Vice President, Marketing & Strategy with the U.S. Green Building Council presented the tower’s LEED Platinum plaque to project manager Axel Zemborain. The tower, the headquarters of a Spanish energy corporation in Bilbao, is the first in Europe to achieve Platinum, the highest rating under Leadership in Energy and Environmental Design, or LEED, USGBC’s green building rating system. To qualify for the top rating, the building met 48 of 62 criteria related to building site, water efficiency, energy, materials, indoor environmental quality and innovation.

To achieve the Platinum rating, the project team used a wide array of sustainable design strategies. A continuous loop of 30°C (86°F) water runs through the building to assist in heating or cooling demands, depending on the season and time of day. Most significantly, the Torre Iberdrola has a highly efficient double-wall glass façade. Cool interior air circulates through the cavity between the walls, drawing heat up and into the ceiling plenum, allowing the building to re-capture heat from its exposed areas and delivering it to where the demand is highest. Potable water consumption is reduced by 40 percent over that of a conventional building by using highly efficient fixtures, minimizing the irrigation, and implementing a system for filtration and reuse of greywater.
