New at Celsios: Free tendering service - we do the work for you
Celsios Service Update - June 2025
The decarbonization of buildings often fails not because of a lack of will or budget - but because of the time spent on tenders. This is precisely where we come in with our new service.
We know the problem from our own experience
Before I founded Celsios , I was responsible for over 300 buildings myself. The reality was that we had to painstakingly research service providers, send out inquiries and compare offers for each project. Weeks went by before we could even make a decision.
This time is then lacking for what really counts: The strategic development of the portfolio.
Our new service: tenders at the touch of a button
We are now offering all asset managers a free tendering service:
You tell us: Which building, which measures, which criteria
We take over: The complete coordination with our 50+ certified partners
You receive: A structured comparison of offers within 48 hours
No hidden costs. No obligations. Only time savings.
Available services - from A for analysis to Z for certification
With our partner network, we cover all 18 areas of expertise in building decarbonization:
Energy consulting and renovation roadmaps
PV systems and renewable energies
ESG certifications (BREEAM, DGNB, GRESB)
Heating modernization and HVAC optimization
E-mobility and charging infrastructure
Funding advice
... and many more
How it works in practice
Send request: An e-mail with the property address and desired services is sufficient
We coordinate: We contact suitable partners within 24 hours
Receive offers: You will receive the first qualified offers after just 48 hours
Decide freely: You choose the partner that suits you
Why are we doing this for free?
Quite simply, we believe in long-term partnerships. If you are convinced by our service, you might also use our digital platform for your ESG management. But this is not a must - the tendering service remains free of charge.
The initial feedback is promising
During the test phase, we were already able to help several asset managers receive qualified offers for their projects within 48 hours. The time saving: an average of 10-15 working hours per tender.
