NEW YORK, Sept. 6, 2012 /PRNewswire/ -- Diageo, the world's leading premium spirits, wine and beer company, today announced that its New York City office has been awarded the US Green Building Council's (USGBC) Leadership in Energy and Environmental Design LEED-CI (Commercial Interior) Gold Certification, the most prestigious and internationally-recognized standard for sustainable design, construction and operation in the world. This is the second Gold distinction to be awarded to Diageo in the US, with the first awarded last year for Diageo's Chicago office. The Diageo "Spirit" building in Madrid was awarded Gold certification last year as well. "Measuring and managing our environmental impact is essential to the financial sustainability of our supply chain and one of our key business priorities," said John Pursell, Vice President Real Estate and Facilities for Diageo North America. "We are constantly evaluating the efficiency and performance of our facilities and are proud to achieve the LEED Gold certification in our New York office. The second Gold certification is an important milestone toward achieving our environmental goals for our facilities in North America." LEED principles drove Diageo's New York office renovation project from its conception, with Diageo scoring highly in all LEED categories of energy and atmosphere, sustainable sites, indoor environmental quality, materials and resources, water efficiency and innovation in design. The design was focused on leveraging the available natural light, reducing the power required to light the interior. Additionally, 100 percent of newly purchased equipment and appliances are Energy Star rated. Almost half of the new furniture is made up of recycled materials and 32 percent of furniture was reused. In addition, 95 percent of the refuse generated during construction was recycled and nearly a quarter of the materials used in the project were manufactured within 500 miles of the site. Developed by the USGBC in March 2000, LEED provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions. The certification process evaluates all construction standards regarding sustainability and respect for the environment. According to the USGBC, LEED-CI is the recognized system for certifying high-performance green interiors that are healthy, productive places to work; are less costly to operate and maintain; and have a reduced environmental footprint. LEED-CI enables tenants and designers to make sustainable choices for their specific space, especially when control over entire building operations is not possible.
