HKL Ingenieurgesellschaft mbH: Expert planning in Building Systems Engineering – A mystery?

Since its foundation in 1990, HKL Ingenieurgesellschaft mbH has a great passion for technology, innovation and is interested in good architecture. Thanks to our central location in Erfurt – often considered the middle of Germany – we can provide our services to customers across Germany and Europe.

Closely working together with property owners, users and architects, the company can provide customized, holistic and innovative planning approaches of technical equipment and building automation for both private and public buildings. This way, for example, factories are equipped with complex air-conditioning units or historic objects receive modern building technology.

The requirements which we encounter are very complex, thus static calculation methods often reach their limits. This is why our service portfolio was amended by dynamic simulation and air flow calculation continually during the last few years. This enables us to provide customers with truly reliable economic feasibility studies to support them in their respective decision making process. Our goal is to ensure the best possible user comfort and a careful use of resources while at the same time reaching a high level of customer satisfaction.
