Jones Lang LaSalle (JLL) has completed retrofitting all 6,514 windows at the Empire State Building as part of its work as program manager of the property's $550 million upgrade initiative. Retrofitting all the windows was one of eight components of the building's energy and sustainability retrofit program that was launched this past year to reduce total energy usage at the landmark. Retrofitting the more than 6,500 thermopane windows at the Empire State Building entailed adding new components to the glass and sashes to create triple-glazed insulated panels that reduce summer heat load and winter heat loss. The groundbreaking process reused 96% of the existing glass and frames, and retrofitting the windows alone is expected to directly reduce building energy costs by more than $400,000 annually. The JLL team overseeing the assignment was led by Raymond Quartararo, international director, with the company's New York office. The company's work on the energy and sustainability retrofit program was led by Dana Robbins Schneider, VP and northeast market lead for Energy and Sustainability Services, also with the firm's New York office. "The decision to retrofit the windows at the Empire State Building rather than replace them was truly innovative, as this approach had never before been attempted," said Schneider. "We were able to re-use in excess of 96% of the existing materials in the windows while more than doubling their overall performance. In addition, the expense of retrofitting the windows at the Empire State Building was nearly 70% less than it would have cost to replace them outright. We hope this project will encourage and motivate other building owners to consider retrofitting their windows to improve overall building performance." The Empire State Building's energy retrofit project was announced in April 2009 by Anthony Malkin, owner of the Empire State Building Co., along with the Clinton Climate Initiative, Johnson Controls, JLL and the Rocky Mountain Institute. The initiative partners also offered the Empire State Building as a template to retrofit existing, older structures throughout the country with energy efficient infrastructure, equipment and operation strategies. When the retrofit program is complete, the landmark building is expected to reduce total energy usage by more than 38 percent, energy costs by $4.4 million annually, and carbon emissions by 105,000 metric tons over the next 15 years. The project overall is estimated to create more than 140 direct and indirect jobs. JLL was selected as program manager by the Empire State Building in 2006 to oversee its overall capital improvement program, which includes the energy and sustainability retrofit program. The effort was designed to facilitate traffic flow, enhance security, improve visitor queuing areas and restore the splendor of the building's historic Art Deco finishes. The work also included renovation of the 86th and 102nd floor observatories. Other elements of the energy retrofit include: Radiator Insulation Retrofit - Added insulation behind radiators to reduce heat loss and more efficiently heat the building perimeter. Tenant Lighting, Daylighting and Plug Upgrades - Introduction of improved lighting designs, daylighting controls, and plug load occupancy sensors in common areas and tenant spaces to reduce electricity costs and cooling loads. Air Handler Replacements - Replacement of air handling units with variable frequency drive fans to allow increased energy efficiency in operation while improving comfort for individual tenants. Chiller Plant Retrofit - Reuse of existing chiller shells while removing and replacing "guts" to improve chiller efficiency and controllability , including the introduction of variable frequency drives. Whole-Building Control System Upgrade - Upgrade of existing building control system to optimize HVAC operation as well as provide more detailed sub-metering information. Ventilation Control Upgrade - Introduction of demand control ventilation in occupied spaces to improve air quality and reduce energy required to condition outside air. Tenant Energy Management Systems - Introduction of individualized, web-based power usage systems for each tenant to allow more efficient management of power usage. As part of the energy retrofit Jones Lang LaSalle oversaw a highly collaborative team that conducted an innovative process for analyzing and retrofitting existing structures for environmental sustainability. The program is the first comprehensive approach utilizing an existing building to model steps for the reduction of energy consumption, and to share details of the team's finding to create a replicable model for similar projects around the world. -more- The retrofit for greater energy efficiency carried an incremental cost of approximately $20 million over the previously planned building renovations, taking into account savings from redirected expenditures and additional alternative spending in tenant installations. Although current funding is sufficient to cover the cost of the initiative, alternatives are being explored to gain lower-cost financing based on annual energy savings in excess of $4 million when implementation is complete. The window retrofit project, along with other details of the sustainability initiative, are showcased in the Empire State Building's recently unveiled $2.0 million, multi-media sustainability exhibit in its world famous Observatories' second floor visitors center. The exhibit is open seven days a week from 8 a.m. to 2 a.m. For more information on the Empire State Building's sustainability initiative and the window retrofit, visit www.esbsustainability.com.

Working with governments and businesses around the world to tailor local solutions that are economically and environmentally sustainable, CCI focuses on three strategic program areas: increasing energy efficiency in cities, catalyzing the large-scale supply of clean energy, and working to measure and value the carbon absorbed by forests. In each of these programs, CCI uses a holistic approach to address the major sources of greenhouse gas emissions and the people, policies, and practices that impact them. CCI serves as the action arm of the C40, an association of large cities around the world that have pledged to accelerate their efforts -more- to reduce greenhouse gas emissions, and of which New York is a member.
