Article 24 of the Renewable Energy Directive (RED II) addresses district heating and cooling (DHC) by strengthening the role of consumers (paragraphs 1, 2, 3) and by encouraging an increase of renewable energy sources (RES) in DHC (paragraphs 4, 5, 6). According to paragraph 1 of this Article,...

Homeowners face a water versus heat tradeoff when it comes to replacing thirsty grass lawns with water-conserving landscaping, a process touted by water agencies in the U.S. West as a top way to conserve water. Using nearly 200,000 rebate records and remotely-sensed temperature data from...

Das Ziel der Treibhausgasneutralität bis zum Jahr 2045 stellt die Fernwärmesysteme vor große Herausforderungen, die durch den Krieg in der Ukraine noch verschärft werden. Um Kohle als Energieträger für die Versorgung von Wärmenetzen zu ersetzen und eine langfristig klimaneutrale, von...

In this study, the actual operation status of the cogeneration model was investigated to examine the difference between the theoretical evaluation and the field operation situation. The adequacy of the installed capacity of the cogeneration system was assessed by using in-house developed...

Die vorliegende Analyse gibt einen Überblick über mögliche Ansätze, um im Markt der leitungsgebundenen Wärme Preistransparenz zu gewährleisten und die Preise zu regulieren. Dabei werden die Ansätze in Deutschland mit denen in anderen europäischen Ländern verglichen. Darüber hinaus wird...

District heating can help to integrate renewable generation within the electricity domain and thus reach climate and energy goals by providing flexibility services and stabilizing the electricity grid. To determine the economic viability of such flexibility services, this work presents a...

This report was created within the project "Overview of Heating and Cooling: Perceptions, Markets and Regulatory Frameworks for Decarbonisation." The focus of this report is on the evaluation of the final cost for owning and operating district heating (DH) connections and heat pumps (HPs) for...

Using industrial excess heat for residential heating can increase energy efficiency and thus be part of the solution to achieving the EU's climate targets. However, industrial plants are often located in industrial areas and thus away from residential areas. Therefore, the excess heat has to be...

In order to verify the versatility of the experimental correlations of the previous work, and the same experimental method from the previous work is selected to obtain the heat transfer characteristics of the salt and subcritical water in the model of tube-shell heat exchanger. and it is...

District heating grids worldwide are still powered predominantly by combustion of fossil fuels. In order to decarbonize them, new designs for the district heating and cooling systems are required. This paper describes the laboratory at the research center for Combined Smart Energy Systems...

The feasibility of using air-water heat pumps to provide residential and industrial buildings with heating, cooling and ventilation requires taking into account a large number of different factors, such as the estimated and average outdoor temperature for the heating period in the considered...

Numerical simulations of district heating and cooling networks constitute a valuable tool for system design and optimization. This paper presents a novel thermo-hydraulic network model, which addresses particularly large 5th generation district heating and cooling (5GDHC) networks. We paid...
