Our company actively participates in research projects focused on energy efficient building control and advanced monitoring. Our company cooperates with several research institutions and universities: ETH Zurich, KU Lueven, CTU Prague, NTIS Pilsen.
In cooperating with CTU, we had developed and successfully applied a unique predictive controller for buildings. This controller is based on online mathematical optimization. It uses weather forecast together with a mathematical model of a building in order to find an energy optimal strategy for building control. This controller is in full scale operation on a CTU building (70 000 m2) since 2008. In 2012, the controller was applied to the pilot building of the Geotabs project. The controller was also used for energy saving analysis in the OptiPremir project.
The project (supported by the Ministry of Industry and Trade of the Czech Republic, 2006-2011) was focused on advanced building control and fault detection. We developed and successfully applied a predictive controller for CTU building in Prague (70 000 m2). Thanks to the predictive controller, the energy consumption was reduced by 16-27%. This was one of the first full scale applications of predictive control on a real building worldwide.
The objectives of the OptiPremier project were (i) the modeling of the newly built „Icade Premier House 1“ buildingin Munich, and (ii) the study and optimization of the indoor temperature control in the office part of the building. The control strategies considered were Rule-Based Control, as implemented in the real building, and so-called Model Predictive Control. The focus was on energy efficiency and thermal comfort in the office rooms. An interdisciplinary team from academia and industry executed the project.

The overall aim of the GEOTABS project is to improve system design and control of GEO-HP-TABS in office buildings by using monitoring, comfort survey and simulation data. Hereby, improved design is characterized by increased energy performance as well as increased convenience for future commissioning, while comfort is guaranteed. Monitoring data and simulation data constitute a huge source of information, which is not yet fully exploited to improve system design and control. Moreover, very little is known about users’ comfort experience in TABS buildings. Therefore, a generic international comfort survey tool will be developed and applied to TABS buildings. These data form, together with a current practice review, the ideal foundation in the development of scientifically sound guidelines for improved design and control.
The project focuses on the application Integrated Room Automation (IRA) in office buildings. IRA deals with the automated control of blinds, electric lighting, heating, cooling, and ventilation of individual building zones. OptiControl combines the newest developments from the fields of building technologies, numerical weather forecasting and control engineering. The project develops and tests novel, predictive control approaches plus corresponding software modules to be incorporated in commercial building automation systems.

The project (supported by Ministry of Industry and Trade of the Czech republic, 2009-2012) was focused on microhardness testing. Energocentrum Plus was responsible for software implementation and for development of image processing algorithms.

The main objective of the project is the increase of the nystatin antibiotics production achieved by decreasing the variability of outcomes of the respective batches of the fermentation phase of the production. The means to achieve the objective is the design of knowledge-based control of fermentation processes as a supervisory level to the classical, current control system. Consecutively, after the process analysis, its mathematical and physiological models will be created, and based on these, the specific knowledge-based control strategy will be designed, which will bring savings of energy and input feeds, and will increase the yield of the fermentation process. The designed solution will be applied on the production of the nystatin antibiotics, while being easily transferable onto production of other antibiotics produced by the Streptomyces genus.
