; ; Optimizing energy usage is becoming an economic necessity for existing buildings. Non-invasive sensors and sensor networks are key technologies for efficiently achieving this goal, since it is of utmost importance that existing hydraulic systems are not changed and the engineering effort for installation remains minimal. This paper presents a data-driven approach that should allow low-cost installation of sensors at arbitrary points of the building and then retrieve the structure of the hydraulic system from the recorded sensor values. The architecture as well as first preliminary results from field test buildings are presented.403Scopus© Citations 1 - PublicationNumerical and experimental characterization of a novel low-cost thermal air flow sensorTo enable highly efficient operation of large scaled ventilation systems a continuous measured and well located air flow monitoring for control purposes and energy management is needed. The air flow monitoring solution is targeting low manufacturing cost as well as sufficient accuracy when operating near complex duct flows like pipe bends and tees. Therefore, a novel, low-cost, thermal air flow sensor, which takes non-uniform velocity profiles into account, is presented and characterized due to its application in heating, ventilation and air conditioning systems. Extensive numerical simulations and experimental investigations in an operating ventilation system show reasonable results and prove basic feasibility of the suggested novel sensor concept.

; Air conditioning systems are among the major energy consumers in buildings. Energy-efficient operation of AC systems is an important step towards better energy management in building automation, but requires efficient monitoring of the energy or enthalpy flows within the AC installation, which is currently still difficult because of the lack of appropriate equipment. This paper introduces a distributed data acquisition system for large-scale AC systems based on low-cost flow sensors implemented by means of standard printed circuit board technology and interconnected via a wireless sensor network. A critical issue for the system installation is the placement of the sensors in the air ducts to obtain representative measurements of the air flow. To this end, extensive aerodynamical simulations are carried out to analyze the flow distributions in typical building blocks for air ducts, particularly with respect to turbulences. The simulation results are compared with experimental data from the literature and are shown to be reliable.143Scopus© Citations 7 - PublicationExponential pattern recognition for deriving air change rates from CO2 data(Institute of Electrical and Electronics Engineers (IEEE), 2017)
