In 10 years, people make use of buildings equally to computers and smart phones today.

a world of digital buildings

Imagine, a whole commercial building can be handled like a smart phone today. Available, not by the end of this century, but by the end of this decade. People and machines will interact with the buildings for daily life purposes. A building will not be longer something you occupy, it will be something you use.

Our living and working worlds are changing rapidly and will be completely digitized in just a few years. At the same time, our existing building stock widely remains at the structural level of the 20th century. This does not provide an adequate basis for a digitized world. It will inevitably have to come to a massive digital transformation of the construction and real estate sector. An operating system has provided the basis for each digital revolution so far. Therefore the company LEITRON GmbH has started to develop a general building operating system LEITROS. Let us introduce you to our vision.

What is a digital building?

A digital building is a physical building with the ability that users (human beings or machines) can interact with it in a digital way. The physical building itself can be digitalized by physical electronic equipment (type 0) or has a virtual twin of its physical building (type 1). Both digital models of the building can be connected in real time, but do not necessarily have to.

Our definition type 0 - a physical digital building

A digital building is a real life building with functionality and equipment ready for digital life and digital workplaces

  • fiber optics
  • smart buildings
  • smart metering
  • smart contracts
  • app ready
  • ready for sharing economy
  • PROPtec / FINtec connectable
  • ...

Our definition type 1 - a virtual digital building

A digital building is a virtual building of the real life building as its digital twin and will be accessible via standard Internet technologies for all purposes of usage and operation

  • virtual and visual
  • real-time data
  • real-time processes
  • accessible via digital building OS
  • user restricted
  • digital building search engine
  • open database and open interfaces standards
  • ...

What is BIM?

Building information modeling, short BIM, is a digital representation of the building to facilitate exchange and interoperability of information in digital format.

From CAD to BIM. The evolution of the BIM method.

And what is the difference?

BIM is a basic element for digital buildings. But today BIM is not ready for building operations management. BIM is not a software system that is able to show real time data of buildings or even control building environments. Therefore digital buildings need separate software systems. We think it will be a general building operating system - a building OS.

BIM in design, construction and operation of buildings

The "BIM Wave" is an forecast of the near future. When more and more building projects will be designed and erected using BIM methods, more and more building owners or operators will start to find solutions for digital building operations using this BIM data.

A digital building Operating System.

The OS will be available via standard browsers and standard hardware. It can be run in every building, in a property management environment or a data computing center (cloud service). And it will use non-standard open source micro-kernel environments for safety & security reasons.

Advanteges of a digital building OS:

A digital building is a physical building with the

  • open & independent software platform
  • simplification of processes
  • data sovereignty & access
  • interoperability
  • third party ready
  • access to fair competition
  • local, data center and cloud ready

A disruption.

What do we think and what are we convinced about?

One of the ‚what’s next‘ questions will be answered by digital buildings. It will become a mega trend inside of digitalization. And it will be a disruption to today‘s real estate industry within the next 10 years all over the world - and is going to change it forever. Especially the asset and property management services will disappear and get automated.

Our team.

Direct and instant communication. 100% digitalized work. Open mindsets and the clear vision that sharing of resources is better than proprietary environments. Our start-up team strives for innovation and modern globalized perspectives. We develop our building OS named LEITROS.













Our solution partners.

We create solutions, together with people who are passionate about technical developments. We integrate fantastic simple solutions in the digital building environment and create a holistic building operating system.

air-Q powered by Corant.

The Corant GmbH, presents air-Q – a device to analyse indoor air quality. Humans spend up to 90% of their time inside. There, everyone respires “his” or “her” own air which is determined by factors such as the interior, the construction materials, the number of people in the room and the ventilation habits. The vision of air-Q is one of smart rooms that, with the aid of relevant environmental data, allow people to live and work healthier and more productively, and even save costs.

Our responsibility.

We think digitalization gives our society the opportunity to rethink our behavior at all. We change procedures, we change the way things work - so we can also change the way we think. Digital buildings are open for access. Information transparency helps to save energy. Standardization in design, construction and operation will reduce costs and in turn the rents to be paid by tenants. The digital building program is an opportunity to rethink the way we work and live.

responsibility 1: save resources

Digital buildings will help to save resources and reduce some of the ecological stress societies produce. Collecting and comparing data from digitized buildings will reveal potential saving effects and optimize the input of electricity, heat and water. Landlords and leaseholders can analyze current and future consumption and adapt their strategies to save costs, which in turn help to save resources.

responsibility 2: analog human beings

We cannot predict if human beings are getting digitized themselves in the future, but our mission is to support each one who prefers his existence the way it has been before: since the first days of mankind, inventions help and assist us to make life more comfortable. We long to continue this approach and want to transfer innovation also to analog human beings in terms of the dialog. We want to support decision-makers to develop an understanding of inherent processes and logics in managing facilities and (real estate) properties.

responsibility 3: social awareness

The initial motivation for digitizing buildings may vary for different actors in the real estate markets. We feel obliged to address the issue and our agenda to everyone. We are convinced that the economy in general and decision-takers should use the full potential of new techniques and innovations and transfer the advantages to the entire society.

responsibility 4: simple buildings

Keep it simple. This is one of our primary directives. Digitalization shall make things not more complicated than before. It shall solve problems and do not create additional ones. No matter how difficult and complex a new technique may be, the outcome of its use should always adapt to the needs of those affected: transparency and intuitive access to data. Due to this simplicity everyone can make the right decisions by themselves. That is our understanding of situational awareness in digitized worlds.
