Smart Facility Management – the future is now

OK ZT-GmbH takes care of your real estate throughout its entire life cycle and already thinks about the necessities of operation during construction.

In this area, we have spent the last few years developing a digital tool with partners for the implementation of building control technology, maintenance support and operating cost monitoring, and have already installed it several times for clients.

Smart facility management already helps our clients to reduce their carbon-footprint.

On May 9, 2023, we were allowed to present this tool at a Matrix42 Experience Day on-stage and received a lot of positive feedback.

A CO2 certificate is much more than just a “sticker”

LEED, Γ–GNI, BREAM, EU-Taxonometry, klima-aktiv and other certificates are effective instruments that help to realize sustainable and environmentally friendly projects. But how do you implement these certificates effectively?

As OKZT, we can support you in successfully obtaining these certificates. But our goal goes far beyond simply obtaining the certificate. Rather, it is about achieving the associated goals and using the benefits specifically for your project.

Whether for conversions or new properties, sustainability as a planning principle has long been a high priority at OKZT.

Our cooperation with renowned institutions, such as Γ–GNI, Energieforum KΓ€rnten and Energieforum Γ–sterreich give us a direct line to developments and current standards.

A CO2 certificate is a recognition of your efforts to promote environmentally conscious and sustainable construction. It is proof that your project meets the highest standards and has a positive impact on the environment.

If you are interested in implementing such projects and would like to realize the full potential of these certificates, please do not hesitate to contact us at π’”π’–π’”π’•π’‚π’Šπ’π’‚π’ƒπ’Šπ’π’Šπ’•π’š@π’π’Œπ’›π’•.𝒂𝒕.

Together we can help create a sustainable future and make positive changes for our environment.

Hydropower plants are a challenging engineering discipline …

… to which we have dedicated ourselves for many years. Our expertise covers the planning, calculation and supervision of projects at home and abroad.

In addition to the construction of new plants, our focus is also increasingly on the conversion and revitalization of existing hydropower plants. We recognize the value and potential of such projects and are committed to further optimizing hydropower generation.

Currently, work is starting on the refurbishment of the Afritz power station for Kelag Energie. In close cooperation with the Kelag team, we as OKZT are responsible for the structural design and implementation planning for this challenging project.

Hydropower is a clean and renewable energy source that plays an important role in the energy transition. With our commitment and expertise, we are helping to make the most of this valuable resource and drive sustainable energy generation.

If you are interested in hydropower projects or need support in planning and implementation, we are at your disposal. Contact us at to learn more about our hydropower services.
