Empire State Building goes green

World famous landmark gets green gold certification: retrofit will save over $4m and 7000 tons of emissions a year

The Empire State Building has been awarded LEED® Gold for Existing Buildings certification as further recognition from the $550 million Empire State ReBuilding program. The Empire State Building is the tallest and most well known building in the U.S. to receive LEED certification.

The 2.85 million-square-foot building is celebrating its 80th anniversary while nearing completion of its renewal and repurposing to meet the needs of 21st Century businesses.

It is one of a small number of National Historic Landmarks to earn the designation, which was established by the U.S. Green Building Council (USGBC) and verified by the Green Building Certification Institute (GBCI).

The retrofit conducted by Johnson Controls and Jones Lang LaSalle is guaranteed to reduce the building's energy consumption by more than 38 percent and should save $4.4 million in energy costs annually, representing an approximate three-year payback of the cost of implementation. The building gained ENERGY STAR certification in 2010 and has maintained ENERGY STAR certification in 2011.

The improvements also reduce carbon emissions by an estimated 105,000 metric tons over 15 years. In January 2011, Malkin agreed to buy carbon offsets totalling 55 million kilowatt hours per year of renewable energy, making the Empire State Building carbon-neutral.

"When it was built, the Empire State Building instantly became an icon of its era. Now, due to this remarkable investment in energy efficiency, the Empire State Building will be an icon of the 21st century as well, leading our current era in the retrofitting and upgrading of existing buildings to meet modern energy conditions," said David Bragdon, Director of the Mayor's Office of Long-Term Planning & Sustainability.

Beyond energy efficiency, activities at the Empire State Building which helped achieve LEED Gold certification include:

• Installation of ultra low-flow fixtures in the building's restrooms
• Use of green cleaning supplies and pest control products
• Recycling of tenant waste and construction debris
• Use of recycled paper products
• Use of recycled content carpets, low off-gassing wall coverings, paints, and adhesives
