Amid nearly freezing temperatures, a principal reportedly turned off the heat at Ansford Academy in England to show how the school could reduce its carbon footprint.

Principal Rob Benzie came under fire from staff and parents, who called the plan "beyond stupid," according to The Sun.

"I've never worked in such cold," one teacher told The Sun. "I'm all for saving the planet, but this was barbaric."

Students donned coats, hats and scarves in their classrooms as the temperature dropped to 34 degrees.

"Turning the heat off in December is just mental," one parent told The Sun.

Benzie defended the experiment, which he said was an idea pitched by students in the school's eco-group.

"I'd like it to be a regular event. We have too much heating -- sometimes I have to turn it down as it can make students fall asleep," Benzie told The Sun.
