Next time you’re heading into the building, take the spin. Using the revolving door isn’t just about looks or habit, it’s a simple way to help keep our buildings comfortable, efficient, and energy smart.

Here’s the easy science behind it. Traditional swing or automatic doors open wide, allowing large amounts of outside air to rush in or out. Revolving doors, on the other hand, act as a constant seal. They stay mostly closed, keeping indoor air inside and outdoor air where it belongs. In fact, research shows that using a revolving door instead of a swing door keeps up to eight times more treated air inside the building.

Why does that matter?

• • In winter, warm air stays in.
• • In summer, cool air doesn’t escape and hot air stays out.
• • Fewer cold drafts and heat blasts near entrances mean a more comfortable experience for everyone—especially our reception teams and guests.

When indoor temperatures stay steady, heating and cooling systems don’t have to work as hard. That reduces energy use, lowers wear on equipment, and helps shrink our environmental footprint. Good for the building, and good for the planet.

And the impact adds up quickly. Every time you choose the revolving door, we save:

• • 36 watt-hours of electricity—enough to power an LED desk lamp for more than an hour.
• • 3 grams of CO₂, kept out of the atmosphere.
• • Better lobby comfort, with fewer blasts of hot or cold air at the entrance.

The best part? It only takes a few extra seconds. When everyone makes that small choice, those moments turn into meaningful savings.

So next time you come in or head out, give the revolving door a spin. It’s a small action that helps create a more comfortable, efficient, and sustainable workplace for all of us.
