Analysis of the impact of thermo-modernization on heat losses resulting from heat transmittance and thermal comfort in the building

Przyjmuje się, że każdy zabieg dociepleniowy redukuje zużycie energii. Niestety nie zawsze termomodernizacja osiąga zamierzony cel, szczególnie w przypadku złego wykonawstwa, a ponadto, na co wskazują badania autorów, niejednokrotnie pogarsza ona warunki mikroklimatu wewnętrznego pomieszczeń. Dla zilustrowania tego problemu w niniejszym artykule przedstawiono wyniki pomiarów komfortu cieplnego w lokalu w budynku, w systemie W-70 wykonane po zabiegach termomodernizacyjnych. Ponadto za pomocą symulacji przedstawiono wpływ poszczególnych etapów termomodernizacji na bilans energetyczny budynku.It is assumed that any improvement of the thermal profile of the building reduces the energy losses. Unfortunately, thermo-modernization is not always successful, particularly when the performed works are of bad quality, what is more, which is indicated by the research, the thermo-modernization works often lead to deterioration of the internal micro-climate of the rooms in the building in question. In order to illustrate this problem, the present article analyzes the results of thermal-comfort measurements in a dwelling located in a W-70 type building, after the thermo-modernization works are carried out. What is more, the simulation was used to illustrate the impact that the individual stages of thermo-modernization have on the energetic balance of the building

Impact of the thermal bridges in the existing and the modernized W-70 system buildings

W artykule przedstawiono problem występowania licznych mostków termicznych w budynkach systemowych, które są wynikiem technologii ich wykonywania, a także podejmowanych metod ich docieplenia. Zaprezentowano również analizę termiczną typowego złącza systemowego ZWO-S-ZWO , w którym wyznaczono niezbędne do analiz termicznych wartości U, Ψ, Q, fRsi, φ. Uzyskane wyniki poddają w wątpliwość nadmierne pogrubianie izolacji poza wymagane Umin, a wręcz ukierunkowują na dokładniejszą analizę problemu docieplenia pod względem dopracowania wszystkich jego szczegółów.The article presents the problem of so called thermal bridges in the system-based structures of the buildings, resulting from the technology used to perform the works, and from the undertaken attempts and methodologies of improving the thermal profiles of these buildings. A thermal analysis of a typical ZWO-S-ZWO systemic thermal connection is also presented in the article. The analysis determines all of the key values used in the thermal analyses: U, Ψ, Q, fRsi, φ. The achieved results make it doubtful, whether excessive expansion of thickness of the isolation, beyond the required minimum U value. We may even state that this suggests that a more accurate analysis of the thermal improvement would be required, within the scope of refining all the details

\u201cLogically, We Quite Agree with the IARC\u201d: Negotiating Interpersonal Meaning in a Corpus of Scientific Texts

This chapter extends the scope of a previous study (Fusari 2017 and in press 2018) of the reception, by a range of scientific journals featured in the database Elsevier Science Direct, of a 2015 report (IARC 2015) in which the International Agency for Research on Cancer officially incorporated red meat in Group 2A carcinogens (probably carcinogenic to humans) and processed meat in Group 1 (carcinogenic to humans). For this study, we have built a 384,491 words corpus, fully POS-tagged, and partially parsed using a systemic functional grammatical formalism. While the previous stages in this project concentrated on ideational meaning, addressing the use of mass vs. countable nouns, nominalization, the experiential structure of the Noun Group, and patterns of Transitivity, this new step moves beyond representation (Glenn 2004; Gupta 2006; Stibbe 2014; Cook 2015), to explore interpersonal meaning. This area of meaning is less widely studied with corpus approaches, largely because of the greater difficulty, both technical and epistemological, of analysing Tenor with a corpus-assisted approach (Fuoli 2018). Our aim is to analyze how the roles of the various Participants (IARC, scientific community, general public) in the discursive construction of meat carcinogenicity are negotiated. To achieve this aim, we rely on the notions of Attitude, Engagement and stance, in terms of both Appraisal theory (Martin & White 2005) and interactional metadiscourse (Hyland 2005; 2017; Jiang & Hyland 2017). We concentrate specifically on attitudinal Values, Graduation, comment Adjuncts, modal verbs and personal pronouns. The results show that the scientific literature exemplified in this corpus does not aim to settle the meat/cancer controversy once and for all, but rather to \u201cpersuade readers [i.e. other members of the relevant discourse communities] of the scientific acceptability of the knowledge claims presented\u201d (Allen, Qin & Lancaster 1994, p. 280). Therefore, the discursive construction of meat carcinogenicity should not be seen only in terms of relating objective facts and hard data about the levels of risk involved, but also in terms of \u201cdialogism\u201d (O\u2019Hallaron, Palincsar & Schleppegrell 2015), which is equally - if not more - important to reach a shared interpretation (Fern\ue1ndez Polo 2018) of scientific facts
