Empire State Building Cutting Energy Use by 40 Percent

The owners of the Empire State Building announced Monday they will invest $20 million in the 80-year-old skyscraper as part of a plan to cut the building’s overall energy use by 40 percent.

Projections from the Clinton Climate Initiative, Johnson Controls, Inc., and the Rocky Mountain Institute showed the building will save $4.4 million a year—and qualify the building for a LEED Gold certification—after the project is complete in a few years.

The thing I like most about this project is how they’re going to save that energy and cut their carbon output: They’ll be retrofitting windows and radiators, and installing new lighting and ventilation systems—all in the name of efficiency.

The Rocky Mountain Institute and its founder, Amory Lovins, have been promoting energy efficiency for more than two decades now. As Lovins told Mother Jones last May, it’s one of the cheapest and best ways to save money and cut carbon.

MJ: If you had $1 million to invest in the energy sector, where would you put it?

AL: Efficient use. I want to do the cheapest things first to get the most climate protection and other benefits per dollar. Buying micropower and “negawatts” [Lovins’ term for efficiency measures] instead of nuclear gives you about 2 to 11 times more carbon reduction per dollar, and you get it much faster.

In other words, owners of older buildings don’t have to wait around for cleaner energy—and a smart grid to supply it—to proliferate before they can cut carbon output and energy use. And Lovins thinks the this project in particular could “help inform and inspire [similar] initiatives.” In a building so iconic, the project certainly sets an example. If the cost-saving projections hold, it should turn into a trend.

A BETTER WAY TO DO THIS?

We have an ambitious $350,000 online fundraising goal this month and we can't afford to come up short. But when a reader recently asked how being a nonprofit makes Mother Jones different from other news organizations, we realized we needed to lay this out better: Because "in absolutely every way" is essentially the answer.

So we tried to explain why your year-end donations are so essential, and we'd like your help refining our pitch about what make Mother Jones valuable and worth reading to you.

We'd also like your support of our journalism with a year-end donation if you can right now—all online gifts will be doubled until we hit our $350,000 goal thanks to an incredibly generous donor's matching gift pledge.
