The energy efficiency program is the first comprehensive approach that integrates many steps to use energy more productively. The program is expected to reduce energy consumption by up to 38 percent and will provide a replicable model for similar projects around the world. Work has already commenced, and building systems work is slated to be completed by year-end 2010. The balance of the work in tenant spaces should be concluded by end of 2013. Work that is scheduled to be completed within 18 months will result in over 50 percent of the projected energy savings. The balance will be an additional 36 months completed by 2013.

The project will prove the viability for energy efficiency retrofit projects to dramatically increase building energy efficiency and reduce its overall carbon output with sensible payback periods and enhanced profitability.

At the end of the project definition process, the team analyzed the steps to be taken in conjunction with other steps towards sustainability as part of the Empire State ReBuilding program within the framework of the existing USGBC LEED rating system. Internal calculations show that the Empire State Building will be able to qualify for GOLD certification for Leadership in Energy and Environmental Design (LEED) for Existing Buildings, and ownership intends to pursue such certification.

“Commercial and residential buildings account for the majority of the total carbon footprint of cities around the world – over 70 percent in New York City. Beginning in February 2008, the Empire State Building has been used as a test bench to create a replicable process to reduce energy consumption and environmental impacts,” said Anthony E. Malkin of building owner, Empire State Building Company. “Most new buildings are built with the environment in mind, but the real key to substantial progress is reducing existing building energy consumption and carbon footprint.”

“This innovative process, which has developed new techniques for modeling and organizing an integrated program, offers a clear path to adoption around the world, leading to significant reductions in greenhouse gas emissions,” according to Malkin. “Along with other steps taken, in recycling waste and construction debris, use of recycled materials, and green cleaning and pest control products, the model built at the Empire State Building will meaningfully speed the reduction in energy consumption and environmental impact and allow more sustainable operations – while simultaneously enhancing profitability and tenant comfort. This is a real program, happening in real time, creating real green jobs.”

The project partners used existing and newly created modeling, measurement and projection tools in a new and repeatable process to analyze the Empire State Building and establish a full understanding of its energy use as well as its functional efficiencies and deficiencies. This provided actionable recommendations along a cost-benefit curve to increase efficiency and without harming bottom line performance. In reviewing more than 60 optional activities, the team identified eight economically viable projects, applicable to building-wide renovations, electrical and ventilation system upgrades and tenant space overhauls that will provide a significant return on investment, both environmentally and financially.

“Not only will this project dramatically reduce the Empire State Building’s environmental impact, but now we’re able to do it in a way that provides meaningful costs savings to the building as well as its tenants,” said Raymond Quartararo, International Director, Jones Lang LaSalle.

With an initial estimated project cost of $20 million, additional savings and redirection of expenditures originally planned in the building’s upgrade program, and additional alternative spending in tenant installations, the Empire State Building will save $4.4 million in annual energy savings costs, reduce its energy consumption by close to 40%, repay its net extra cost in about three years, and cut its overall carbon output through eight key initiatives, including:
