HVAC and Refrigeration Technology for the Public Sector and Infrastructure
Our Solutions:
Efficient, eligible for funding,
all from a single source.
The renovation backlog is growing—
and so are the requirements.
Climate goals, the German Buildings Energy Act (GEG), and a duty to lead by example: Public buildings must be retrofitted to improve energy efficiency. At the same time, the building stock in many places is outdated, and specific procurement and funding guidelines make projects even more complex. Those who act now can secure funding and avoid the pressure to act under tight deadlines later on.

Our Services for the Public Sector
From individual properties to building portfolios—
all in safe hands.
Whether it's energy-efficient retrofits, heat pumps, or decarbonization, bluu unit is your one-stop partner—from planning to maintenance, GEG-compliant and focused on securing grants.
Energy-Efficient Modernization & Renovation
We bring existing facilities and buildings up to current standards in terms of technology, energy efficiency, and regulatory compliance—step by step and with a focus on securing grants.
Heat Pumps & Decarbonization
We help you transition to sustainable, climate-friendly heating and cooling systems. Consistently tailored to your properties.
Heating, Ventilation, and Air Conditioning (HVAC) Systems for Public Buildings
We ensure a consistent indoor climate in administrative, educational, cultural, and public infrastructure settings.
Heat Recovery
With our solutions, waste heat is utilized rather than wasted. This directly contributes to efficiency and your carbon footprint.
Energy Optimization
We unlock untapped efficiency potential in existing technology, with a measurable impact on consumption and costs.
Maintenance & Service Contract
We offer predictable, preventive maintenance and state-of-the-art remote monitoring. Contract customers benefit from agreed-upon response times through our regional service network.

FAQ
Does bluu unit help me with grant applications?
We provide advice on eligible measures and prepare the technical basis for grant applications. We review specific programs on a project-by-project basis.
Does it make sense to install a heat pump in an existing building?
Often, yes—we assess suitability on a site-by-site basis, including the necessary structural and energy-related requirements.
How does a project involving a public procurement process work?
We are familiar with the requirements and provide documentation that complies with public procurement regulations for each step of the process.
Is it worth modernizing my existing system?
In many cases, yes—renovation is often less expensive than new construction and may be eligible for subsidies. We make our decision based on an assessment of the existing systems.
Does bluu unit also manage multiple properties?
Yes. Through the Group's network of locations, we support distributed sites with regional specialists and a central point of contact.
