This paper discusses the opportunities and challenges of implementing District Heating (DH) in Canada, with focus on the network design and operation. We selected for case study an urban area in Ottawa. First, we proved that the medium-temperature district heating (MTDH)...

This paper presents an innovative low-energy district heating (DH) concept based on low-temperature operation. The decreased heating demand from low-energy buildings affects the cost-effectiveness of traditionally-designed DH systems, so we carried out a case study of the annual energy...

The Danish government plans to make the Danish energy system to be completely free of fossil fuels by 2050 and that by 2035 the energy supply for buildings and electricity should be entirely based on renewable energy sources. To become independent from fossil fuels, it is necessary to reduce the...

The paper presents a method for the design of a low-energy district heating (DH) system, concerning the studies of different pipe dimensioning methods, substation types and network layouts. Computations were carried out separately on each of the pipe segments of which the DH network consisted. A...

As the world's seventh largest wine producer (OIV, 2017), China plays a significant role in the world's wine industry. Classified as neither New or Old World it was recently classified into a "New, New World Category" (CNCCEF, 2009 Lawrence, 2016). This paper presents an overview of the Chinese...

Based on a review of existing acculturation models, an adjusted acculturation model was proposed in this study and a scale for measuring an acquirer's acculturation strategy was developed. We designed an experiment to collect data to validate this scale. Using CR values, CITC and EFA, we...

Testing the tradeoff between child quantity and quality within a family is complicated by the endogeneity of family size. Using data from the Chinese Population Census, this paper examines the effect of family size on child educational attainment in China. We find a negative correlation between...
