Solar Power Meets Air Conditioning—Now at the WTZ!

🔋 Solar Power Meets Air Conditioning ❄️

🌞The sun cools our office. And we do it on purpose.
Sound paradoxical? It isn’t—it’s #sustainability in action here at #WTZ.

We have just installed modern air conditioning systems in our offices in collaboration with Kälte Grohmann —to provide greater comfort and better working conditions on hot days.

What makes it special: The cooling system runs on #solar power generated directly from the building’s own roof.

✅ Our existing #photovoltaic system reliably supplies energy during the day
✅ The new air conditioners use the most electricity at exactly those times
✅ Result: High rate of self-consumption, less electricity drawn from the grid, noticeable savings

🏢 For our employees, this means:
A comfortable indoor climate, without any guilt—because most of the energy used to maintain it comes from our own sustainable sources.

🔄 And thanks to the intelligent control system, the system operates exactly when solar output is at its highest—smart, efficient, and environmentally friendly.

A big thank you to Kälte Grohmann for their professional work!
