Dezentrale Ventilatoren in zentralen raumlufttechnischen Anlagen - Berechnungen zur energetischen Vorteilhaftigkeit
(2015)
Mechanische Lüftungsanlagen sind ein zentrales Elementenergieeffizienter, nachhaltiger Gebäude. Die Luftförderung erfolgt bei zentralen Lüftungsanlagen üblicherweise über einen Zuluft- und einen Abluftventilator in der Lüftungszentrale. Jeder Zentralventilator erzeugt eine Druckdifferenz, die sich an dem Widerstand des ungünstigsten Stranges orientiert. Zum Aufteilen des Gesamtvolumenstroms auf die einzelnen Gebäudebereiche wird die Druckdifferenz in den anderen Strängen gezielt abgedrosselt. Die Abdrosselung stellt ...

Uncertainty and Speculators in an Auction for Emissions Permits
(Springer, 2016-04-16)
Auctions have become popular as means of allocating emissions permits in the emissions trading schemes developed around the world. Mostly, only a subset of the regulated polluters participate in these auctions along with speculators, creating a market with relatively few participants and, thus, incentive for strategic bidding. I characterize the bidding behavior of the polluters and the speculators, examining the effect of the latter on the profits of the former and on the auction outcome. It turns out that in addition ...

An Experimental Investigation into ‘Pledge and Review’ in Climate Negotiations
(Springer Netherlands, 2016-06-06)
A novelty of the new Paris Agreement is the inclusion of a process for assessment and review of countries’ nationally determined pledges and contributions. The intent is to reveal whether similar countries are making comparable pledges, whether the totality of such pledges will achieve the global goal, and whether, over the coming years, the contributions actually made by countries will equal or exceed their pledges. The intent is also to provide an opportunity for countries to express their approval, or disapproval, ...

Output 5 ― Evaluation-Tool
(2017)
Purpose – The purpose of this report is to study the success of short-term intensive study programmes (ISPs) over the short-term perspective and highlight additional lessons for students which might be missed without the experience of working face-to-face on sophisticated tasks in multicultural teams.
Approach/ Methodology – The evaluation of our ISPs was conducted using a quantitative methodology, via questionnaires given to students at the beginning, the middle and at the end of a course. The questionnaire development ...

Socio-economic aspects of irrigation agriculture as livelihood for rural families in Brazil’s semi-arid northeast
(2019-12-04)
Along the lower-middle São Francisco River, in the semi-arid region of northeast Brazil, irrigated agriculture contributes to reduce rural poverty. In the framework of the Itaparica Reservoir construction, three irrigation schemes were implemented in the Pernambuco state to compensate the local population for flooded land. Despite favourable production conditions for irrigated agriculture, many smallholders in the irrigation schemes are facing poverty. To identify socio-economic key indicators on farm income, expert ...

System efficient integration of standby control and heat pump storage systems in manufacturing processes
(2019-05-24)
Prerequisite for system efficiency towards an industrial energy transition is the reducing of energy demand on the process level. In typical manufacturing systems with machine tools and washing machines, the proper design of intelligent standby control and heat pump storage system (HPS) represent high efficiency. The integration of HPS is complicated due to high non-continuity, especially when implementing a standby control system. Our approach aims at designing one single HPS for multiple heat sources and sinks. ...
