Daylight Performance

In the past 30 years, tubular daylight guide systems (TDGSs) have become one of the most popular ways to transport outdoor natural light into the inner space in building design. However, tubular daylight guide systems are not widely used because of the lack of methods to evaluate methods on the suitability of the TDGSs. This study therefore summarizes the daylight performance metrics of TDGSs and presents the estimation methods in terms of field measurements, simulation and empirical formulae. This study focuses on the daylight performance and potential energy savings of TDGSs. Moreover, this study will be helpful for building designers to build healthy, comfortable and energy-saving indoor environment.

Im Rahmen des vom Bundesministerium für Wirtschaft und Energie (BMWi) geförderten Projekts „ETA-Fabrik“ am Institut für Produktionsmanagement, Technologie und Werkzeugmaschinen (PTW) der Technischen Universität Darmstadt konnte die Energieeffizienz von Motorspindeln als Hauptenergieverbraucher von Werkzeugmaschinen durch Einsatz der Synchronreluktanztechnologie gesteigert werden. In der Konsequenz ergeben sich weitere Energieeinsparpotenziale und produktionstechnische Vorteile durch eine gesamtenergetische Betrachtung der Werkzeugmaschine mit Kühlsystem und intelligentem Spindelthermomanagement.   As part of the ‘ETA-Fabrik’ project funded by the BMWi, the Institute of Production Management, Technology and Machine Tools (PTW) of the TU Darmstadt has used synchronous reluctance drives to increase the energy efficiency of motor spindles as main energy consumers of machine tools. Subsequently, new opportunities for energy savings and advantages for the manufacturing process arise by taking a holistic view on machine tools including the cooling system, proposing an intelligent spindle thermal management.

As sleep is unconscious, the traditional definition of thermal comfort with conscious judgment does not apply. In this thesis sleep thermal comfort is defined as the thermal condition which enables sleep to most efficiently rejuvenate the body and mind. A comfort model was developed to stimulate the respective thermal environment required to achieve the desired body thermal conditions and a new infrared sphere method was developed to measure mean radiant temperature. Existing heating conditions according to building code conditions during sleeping hours was calculated to likely overheat a sleeping person and allowed energy saving potential by reducing nighttime heating set points. Experimenting with existing radiantly and forced air heated residential buildings, it was confirmed that thermal environment was too hot for comfortable sleep and that the infrared sphere method shows promise. With the site data, potential energy savings were calculated and around 10% of energy consumption reduction may be achieved during peak heating.
