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,...

We study the impact of text message based information on the household use of air conditioners in southern China using a two-staged clustered randomized experiment among 484 households. In the first stage, we send specific information on how to use air conditioners efficiently to one third...

The quality of perishable products declines continuously during the transportation process, rendering the delivery of a product with good freshness a challenging task in urban areas. We investigate how to plan the activities to preserve the freshness level of products within a specific distance...

Refrigerant is the working medium of refrigeration and air-conditioning systems. Currently, synthetic refrigerants are the dominant refrigerants for cooling, but the emissions from synthetic refrigerants into the atmosphere will destroy the ozone layer. The global refrigeration and...

Data centres (DCs) are large electricity consumers, estimated to account for around 1% of worldwide electricity usage. They release excess heat (EH) during the operation, which can be recovered in district heating (DH) networks. DCs are expected to satisfy the rising demand for digital services....

With the adoption of the EU Climate Law in 2021, the EU has set itself a binding target to achieve climate neutrality by 2050 and to reduce greenhouse gas emissions by 55 percent compared to 1990 levels by 2030. To support the increased ambition, the EU Commission adopted proposals for revising...

The overall objectives of this study are to contribute to optimal pathways for decarbonisation of heating and cooling. The study depicts the perception or image of heat pumps and district heating and cooling among different consumers in the residential, industrial and public sectors, and...
