Energy efficiency pays off

The Field Museum's high-tech, ultra-efficient cooling system doesn't result in less electricity being consumed at the 1.25 million-square-foot institution.

 

But the system is so efficient, it saved almost the entire cost of supplying electricity to the Field's new 200,00-square-foot addition.

 

Before the Field replaced its 36-year-old heating-ventilating- air-conditioning system in 2004, the museum was spending $1,238,000 a year on electricity alone. Last year, after the 200,000-square- foot addition opened, the museum spent $1,300,000 on electricity.

 

So, the museum spent 5 percent more on electricity in 20 percent more space.

 

Even a consumer as rich as a pharaoh can see that's quite a bargain.
