Competence in TGA

Standards and technology keep changing – for you we maintain an overview

Our core competence lies in the integral planning of sustainable building services engineering. We keep an overview for you regarding the latest technological innovations and changing regulatory framework.

Our planning fields:

You need interior or external lighting? We plan and simulate your lighting technology needs implementing the latest legal standards and technological requirements.
We plan acoustic facilities around your needs and in coordination with acoustic designers and architects – no matter how complex and difficult the available space.
Fire technology ensures the protection of those using your buildings. We always design fire technology regarding newest legal standards and of course in coordination with fire fighters.
High air quality ensures better health and therefore better performance. We plan airing systems and air conditioning as part of integral building physical standards.
IT structures and media are changing continuously and getting more complex by the day. In the meantime, they have become the backbone of our economy. We plan flexible, future oriented and efficient data technology.
A comprehensive energy design is the basis for running a building in an energetically sustainable way. Our innovative designs help save money and energy.
Fire extinguishing engineering is an integral part of fire protection. While planning your fire protection we implement the newest and most reliable technology.
We plan water supply and waste disposal regarding your requirements, with the added flexibility for later enlargements or changes of use.
Monitoring building facilities has become indispensable today. We plan building and direct digital control thanks to open interfaces.
We plan your heating facility regarding your needs and by using every resource nature offers. A comprehensive energy concept ensures that the costs for heating are significantly reduced.
Heat levels rise due to the implementation of more technological facilities in a building. Therefore, cooling buildings uses the most energy. We ensure that cooling is produced sustainably and is available quickly.
Safety first! To keep damage away from your real estate we plan customized safety concepts which includes access control, surveillance, fire protection and fire extinguishing technology.
