Empire State Building's Sustainability Retrofit Program Achieves Target With ENERGY STAR Rating of


NEW YORK, May 28 /PRNewswire-AsiaNet/ --

            Iconic Landmark Receives ENERGY STAR Recognition from the

                       Environmental Protection Agency

    The ground-breaking energy efficiency work at the Empire State Building

has achieved a milestone on its journey for sustainability leadership in the

commercial real estate community by receiving an ENERGY STAR rating of 90

from the United States Environmental Protection Agency. The designation for

the Empire State Building signifies that the property's energy performance is

in the top tenth percentile of all commercial office buildings, new and old,

across the nation. An ENERGY STAR rating of 90 was a stated objective in the

iconic property's overall sustainability retrofit initiative launched in

April 2009.

    ENERGY STAR is a governmental recognition program that offers

organizations access to resources that help evaluate their building's energy

performance, reduce energy usage and lessen their overall carbon footprint.

To obtain a certificate, a number of structural and energy output goals must

be met and verified by a licensed engineer. Only buildings with a rating of

75 points or above (out of 100), are eligible for certification.

    Anthony E. Malkin of Malkin Holdings which directs the operation of the

international icon on behalf of building owner Empire State Building Company

stated, "Receiving an ENERGY STAR rating of 90 out of 100 is a significant

accomplishment for any building, and an especially groundbreaking

accomplishment for our Pre-War Trophy Empire State Building." He added, "With

the building's overall energy efficiency retrofit project still in progress,

we may see a higher number when all of the initiatives are completed."

    In April 2009, President Bill Clinton, New York City Mayor Michael

Bloomberg, and the Empire State Building partnership team consisting of the

Clinton Climate Initiative, Johnson Controls, Jones Lang LaSalle, and the

Rocky Mountain Institute announced details of an energy retrofit as part of a

$550 million upgrade program. The overall project is aimed at reinventing the

iconic landmark by restoring and recreating its Art Deco grandeur and adding

state-of-the-art enhancements, while at the same time reducing energy

consumption, operating costs and carbon emissions. Most importantly, the work

pioneered by the team is a replicable model for similar projects around the


    Upon completion in 2013, the $20 million sustainability retrofit is

expected to reduce energy consumption by more than 38 percent and will save

the building over $4.4 million per year. Achieving a high ENERGY STAR rating

was one of the initial goals outlined by the ESB management team, and was

accomplished in less than 13 months.

    The retrofit is comprised of eight key initiatives:

    1. Window Light Retrofit: Refurbishment of approximately 6,500

       thermopane glass windows, using existing glass and sashes to create

       triple-glazed insulated panels with new components that dramatically 

       reduce both summer heat load and winter heat loss.

    2. Radiator Insulation Retrofit: Added insulation behind

       radiators to reduce heat loss and more efficiently heat the building


    3. 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.

    4. 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.

    5. 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 


    6. Whole-Building Control System Upgrade: Upgrade of existing

       building control system to optimize HVAC operation as well as provide 

       more detailed sub-metering information.

    7. Ventilation Control Upgrade: Introduction of demand control

       ventilation in occupied spaces to improve air quality and reduce energy

       required to condition outside air.

    8. Tenant Energy Management Systems: Introduction of

       individualized, web-based power usage systems for each tenant to allow 

       more efficient management of power usage.

    In addition to ENERGY STAR certification, the work at the Empire State

Building would qualify under current standards for LEED-EB Gold certification

from the United States Green Building Council.
