Building Systems Technology

When it comes to building systems engineering, we take a holistic approach and deal with the following areas of work:

 

Building Energy Concepts

 

Analysis of the Building Stock

 

Heat Networks

 

Load Flexibilization in Buildings

 

Monitoring an Operational Analysis

In the field of building systems technology, we deal with the system integration of innovative heat and cold supply (conversion and transfer) and ventilation technologies in buildings and their interaction in districts. Integral planning, comprehensive quality assurance in implementation and effective operational analysis are the keys to energy performance throughout the lifecycle of buildings. Our focus is on "low-exergy systems", i.e. the use of environmental heat as a heat source (outside air, soil, water, solar radiation, waste heat) and the transfer of useful energy with small temperature differences. Heat pump systems (electrically or thermally driven) are a focus of technological realization, as well as grid-connected supply via fifth generation heating grids. The implementation takes place in both: new and existing buildings.

Fluctuating and decentralized energy generation requires increased coordination on the demand-side and the use of flexible operating options for load transfer. Currently, a large amount of new business models for Smart Homes and grid-supportive buildings are being developed: Energy management gateways are used for communication and control of different systems, sensors, meters, supply systems, controllable loads and feedback systems as well as for directed energy efficiency analysis and for optimizing grid operation.

Our range of services extends from planning support in the development of building and renovation concepts to monitoring and the development of optimized model-based operating strategies.
