A numerical model for the energy assessment of a fifth-generation district heating and cooling (5GDHC) network
No full textAchieving the new energy efficiency targets set by recent European directives is not a foregone conclusion for most new building construction projects. The regulatory limits are increasingly stringent and the energy design of buildings becomes more complex and detailed. The transition process towards nearly Zero Energy Buildings (nZEB) now affects almost all European countries, and will be the subject of future challenges in the construction sector. To overcome this problem, not only the role of individual buildings will be crucial, but also the function of future districts, whose cooperation in terms of energy exchange and sharing of resources could be a key aspect to face climate change in a sustainable and efficient way. In this context, a recently studied topic is represented by the fifth generation of low temperature district heating and cooling (5GDHC) networks. The potential of this new generation of thermal networks is to operate at low temperatures, usually below 25 °C, in order to be used as a heat source for the operation of reversible heat pumps, capable of satisfying both heating and cooling needs of the users connected to the network. This feature allows the network users to be prosumers, sharing the heat produced or removed from the network to generate a benefit for other users. Furthermore, this new generation of thermal networks allows an effective integration of renewable sources and low temperature waste heat sources, which can easily be integrated into the network. In this work, a dynamic numerical model has been developed in order to simulate the behaviour of a 5GDHC. A simulation scenario has been defined consisting of 15 different users belonging to the same district and their interaction within the network has been studied. The energy performance of the network was assessed by means of some global performance indexes, with the aim of characterizing the energy potential and response of the network. Thanks to the results presented in this work, it is possible to understand the positive effects of 5GDHC networks, encouraging the spread of this technology and its future application developments
Data flow in living contexts: a systemic analysis for an unsustainable model
Full text linkContemporary residential contexts are characterized by new ICT products and services, which collect data about user behaviours. These data are rarely used to develop services for user or community well-being. By contrast, designers typically focus on these goals in contemporary design. An analysis using Systemic Design tools was carried out to understand the type of data flow that is generated by users in contemporary living
contexts, to identify the main stakeholders of this data flow, and to highlight the main problems of data collection for the users, the community, and the local area. This study aims to contribute to this growing area of research, highlighting its most important problem which designer must solve to realize the right user generated data flow system in contemporary living contexts

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
