Natural Cooling

Natural cooling for a greener future

Our world is getting warmer, and buildings are more affected by the heat than ever. By 2050, experts predict that we will need 30% more air conditioning, which is not good for our energy bills and the environment.

Fortunately, an independent study from Guidehouse offers hopeful insights. If we choose sun protection instead of air conditioning, together we can:

• Reduce energy consumption for cooling by up to 60% by 2050.
• Reduce pollution by 58%, avoiding tons of harmful greenhouse gases.
• Reduce European energy costs by as much as 286 billion euros by 2050.

What does natural cooling mean to you?

  • Savings on costs thanks to significantly less energy consumption compared to artificial cooling.
  • Protection against harmful sun rays for you and your home.
  • Increasing living comfort with less chance of overheating.
  • Increase in the value of your real estate through the improved energy performance of your building.

Choose natural cooling with Harol and contribute to a sustainable future for all of us.
