The most profitable sustainability investment

When it comes to energy efficiency, discussions often lead to replacing windows, replacing lights or additional insulation. But what many don't know is that the biggest energy savings can be made in the plant room.

Energy efficiency

Short payback for AHU replacement

Replacement of older air handling units also has a very short payback period, often between 2–5 years. Compared to, for example, a solar cell investment that has a payback period of 6–10 years.

More and more people are replacing their older air handling units. The savings potential is huge as 85% of Europe's buildings are not considered to be energy efficient.

Have you looked in your plant room? Do you have air handling units that are over 20 years old? If so, there is a lot of energy and money to save.
