Step 3: Multiplying the Power of Change

We've reduced energy demand by making the building's exterior more efficient (Step 1). We've improved building systems, ensuring they're smarter about how they use and distribute energy (Step 2). The final step in making the Empire State Building a beacon of energy efficiency is to involve the people inside – over 20,000 people work here every day and over 3.5 million people visit every year. Transforming the way we consume energy doesn't just mean other buildings need to follow this model; we need individuals around the world to recognize that they can have efficiency without compromise, and that they can contribute to this broader sustainability effort.

Skanska, our tenant on the 32nd floor, will realize over $20,000 in energy savings annually in their new, energy efficient office space. Many of these ideas can be applied to even small homes or apartments, saving you money and improving your quality of life. We need you to spread the word and help multiply the change.

Efficient Lighting & Plugs
Efficient Lighting & Plugs
Compact Fluorescent Lamps (CFLs) consume only 25% as much energy as traditional incandescent bulbs and last up to 15 times longer. The Empire State Building is encouraging all of our tenants to use these more efficient bulbs.

save $15 a year
If you replace just one typical (60 Watt) incandescent bulb in your house with a CFL, you could save $15 a year.
save $53 million a year
If each of our 3.5 million visitors replaced one bulb, we could save $53 million a year.
power a city
If each of the over 100 million American households replaced just one bulb, we would save enough money to power a city of over 1.5 million people for a year.
Daylighting

Day-Lighting
Like most buildings of its time, the Empire State Building was designed to maximize natural lighting. Sunlight pours in through over 6,514 oversized windows, providing an abundant source of light for much of the day, and creating opportunities for us to save energy and money.
   
Task-specific lights instead of overhead lights: "Task-specific" lights can be turned on and off as they are needed, meaning that the whole office doesn't need to be lit with electric lights all the time.   Office layouts: Many offices install walls to sub-divide the space, often blocking access to windows with office walls. This means that interior spaces must rely on electric light. By opening up office layouts, we can take better advantage of the sunlight.   Turning the lights off: Many of us forget to turn off the lights, even when we don't need them. We are encouraging tenants to install light sensors that are able to sense ambient light levels and turn lights down or off when not needed.
Tenant Energy Management

Traditionally, tenants have had very little control over how the energy within their offices is allocated. The Empire State Building wanted to put the power in the tenants' hands.

We are providing tenants with a web-based digital control system that allows them to monitor the way energy is being used in their spaces. An online dashboard gives them full transparency into their energy consumption and helps them analyze the data to find ways to be more efficient.

Finally, every new office suite in excess of 2,500 square feet is individually metered, so tenants can save money through their own actions. Everyone can take a more active role in managing their own energy consumption. Find out when you're using the most energy and look for ways to avoid using lights or temperature control systems when they are not needed.
