According to a new survey of office workers, 69 percent said they would be willing to sacrifice their preferred ideal temperature in the office to help their companies conserve energy.

However, the survey also found that 78 percent are less productive at work when they are too hot or too cold.

Johnson Controls commissioned the survey of nearly 800 American adults who work in offices. The manufacturer said the findings indicate that many workers think their employers could be doing more to be energy efficient. But the challenge for business owners is to avoid a negative impact on productivity.

“Employers may be tempted to turn down the thermostats this fall, but this quick fix could lead to hidden costs,” said Clay Nesler, vice president of global energy and sustainability for Johnson Controls. “Energy-efficient systems and equipment is the win-win alternative, allowing businesses to save energy and money without sacrificing workplace productivity.”

All participants said their office has been too hot or too cold at some point and when that occurs, most said they are less productive. Not only does workplace productivity suffer, individual actions - such as bringing a heating or cooling device into the office - result in increased energy use.

Forty-nine percent of office workers said they have used a fan when it was too hot in their office, and 28 percent used a space heater when it was too cold.

Nearly one-third have left their office building to take a walk outside when it was too hot or too cold in their work space.

Forty-one percent have informed their office manager or custodian of their discomfort.

The survey also found that approximately 69 percent of workers have adjusted their clothing, such as adding a sweater if was too cold or removing a layer if it was too hot.
