Taking into account the energy exchange with a grid overcomes the limitations of energy-autonomous buildings with the need for seasonal energy storage on-site. Although the expression, "Net Zero-Energy Building," appears in many energy policy documents, a harmonised definition or a standardised balancing method is still lacking. This paper reports on the background and the various effects influencing the energy balance approach. After discussing the national energy code framework in Germany, a harmonised terminology and balancing procedure is proposed. The procedure takes not only the energy balance but also energy efficiency and load matching into account.}, language = {en} } @article{VossMusall2011, author = {Voss, Karsten and Musall, Eike}, title = {Null- und Plusenergiegeb{\"a}ude: Allgemeine Bilanzierungsverfahren und Schnittstellen zur normativen Praxis in Deutschland}, series = {EnEVaktuell}, journal = {EnEVaktuell}, number = {IV}, publisher = {DIN Deutsches Institut f{\"u}r Normung e.V.}, pages = {3 -- 5}, year = {2011}, abstract = {Die Begriffe „Nullenergiehaus" oder „Plusenergiehaus" sind in den letzten Jahren national und international zum Inbegriff f{\"u}r die konsequente Zusammenf{\"u}hrung von Maßnahmen zur drastischen Energieeinsparung und optimierter, dezentraler Nutzung erneuerbarer Energien geworden.

These parameters intend to represent perceptual qualities, but were developed without a consistent modeling of room acoustical perception. More recent research proposed comprehensive inventories of room acoustic perception that are purely based on evaluations by human subjects, such as the Room Acoustical Quality Index (RAQI). In this work RA-QI scores acquired for 70 room impulse responses were predicted from room acoustical parameters. Except for Reverberance, the prediction of RAQI factors performed rather poor. In most cases, the sound source had a greater impact on RAQI scores. All analyses are published in an online tool, where users can upload omnidirectional and binaural impulse responses, and instantly obtain and visualize several physical descriptors, as well as predicted RAQI scores for three different sound sources. So far, acceptable prediction accuracy is achieved for Reverberance, Strength, Irregular Decay, Clarity and Intimacy. Larger data sets of evaluated impulse responses are required to improve the model performance and enable reliable predictions of room acoustical quality. Therefore, the administration of RAQI evaluations within the website is currently being developed.}, language = {en} } @inproceedings{vonBergPrinzSteffens2022, author = {von Berg, Markus and Prinz, Lukas and Steffens, Jochen}, title = {Comparing individual perception of timbre and reverberance}, address = {Gyeoungju, S{\"u}dkorea}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-38706}, pages = {5}, year = {2022}, abstract = {Room reverberation alters the spatial impression and timbre of a sound by modulating its spectral and temporal characteristics. Thus, we argue that, on a perceptual level, reverberation basically breaks down into interaural differences and spectro-temporal cues and that the separation of a perceived timbre into a sound source and a surrounding room is a purely cognitive process. To investigate the connection between the perception of reverberation cues and timbre analysis, the sensitivity for changes in reverberation was compared to timbre perception abilities. The Timbre Perception Test was used to measure the perception of the temporal envelope, spectral centroid, and spectral flux of artificial sounds. Sensitivity for changes in reverberation time was tested with a discrimination task using speech and noise with speech-alike spectral and temporal envelopes as source signals. Musical and acoustical expertise was assessed through the Goldsmiths Musical Sophistication Index and self-reports on experience with and knowledge of acoustics. There was a considerable correlation between timbre and reverberance perception ability, but timbre perception and academic experience predicted only 41\% of the variance in reverberance perception. Still, perception abilities related to similar acoustical phenomena seem to be better indicators of listening skills than self-reports on acoustical or musical expertise.}, language = {en} } @techreport{VogelBlaettermann2021, author = {Vogel, Peter and Bl{\"a}ttermann, Patrick}, title = {Investieren unter Nebenbedingungen - Teil 5: Auswahl von Aktien, Datenqualit{\"a}t und Statistik-Ergebnisse}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, issn = {2567-2347}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-28848}, year = {2021}, language = {de} } @techreport{Vogel2017, author = {Vogel, Peter}, title = {Investing as Random Trial}, series = {Trading}, journal = {Trading}, number = {1}, publisher = {Hochschule D{\"u}sseldorf}, address = {D{\"u}sseldorf}, issn = {2567-2347}, doi = {10.20385/2567-2347/2017.1}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-11118}, pages = {39}, year = {2017}, abstract = {We introduce an investment algorithm for a market of individual securities. The investment algorithm is derived from constraints depending on investment parameters in order to limit the risk and to take into account an individual investor. One constraint is devoted to trading costs. Purchased securities are selected randomly among securities that meet the buy condition, making trading a random trial. Simulations with historical price data are demonstrated for a simple example: The buy condition is evaluated on the basis of the price relationship for two subsequent trading days and the sales condition is defined by holding securities only for one day. A trading expert evaluates the expected return for the investment algorithm with respect to the random selection. Thus, the expert informs precisely on how many market players perform using the same investment algorithm. Its findings are for a parametrized set of buy conditions simultaneously, which makes a trading expert a valuable tool for theorists as well as for practitioners. In our example, the trading expert demonstrated clearly a significant mean reversion effect for a horizon of one day.}, language = {en} } @misc{Vogel2018, author = {Vogel, Peter}, title = {Marktdaten}, series = {Trading}, journal = {Trading}, publisher = {Hochschule D{\"u}sseldorf}, address = {D{\"u}sseldorf}, issn = {2567-2347}, doi = {10.20385/2567-2347/2017.1/1}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-15015}, year = {2018}, abstract = {Die in der Schriftenreihe Trading verwendeten Forschungsdaten beinhalten historische Kursdaten, geliefert von Lenz+Partner AG (Deutschland), f{\"u}r eine Auswahl an Aktien.
