LA RIQUALIFICAZIONE ENERGETICA DELL’INVOLUCRO EDILIZIO ATTRAVERSO UN SISTEMA ISOLANTE COMPOSITO. MESSA IN OPERA E MISURA DELLE PRESTAZIONI THE BUILDING ENVELOPE RENOVATION TROUGHT COMPOSITE INSULATION SYSTEM. INSTALLATION AND MEASUREMENT OF PERFORMANCE

More than 60% of the existing building stock in Lombardy Region has been built before the 70’s and it is among the main responsible causes of final energy absorption and corresponding CO2 emissions. In this view, the residential buildings represent the main relevant part with a mean overall performance index of 201.8 kWh/m2a. The promotion of renovation measures for such buildings, also through innovative solutions, is becoming increasingly important for both containing the greenhouse gas emissions and supporting the growth of the construction sector. To this topic, the work presents the energy renovation of a social housing building in the Province of Milan through the application of innovative prefabricated façade panels that integrate both thermal insulation and exterior finishing. In detail, the paper describes, on one hand, the relevant design strategies following the preliminary analysis and, on the other hand, the process of installation; besides, the final performance of the retrofitted envelope is documented by the results of the monitoring campaign

Outer facade retrofitting trough precast insulation panels: method and planning tool applied to an Italian residential building

Much of the required reduction in energy consumption needs to be achieved through the renovation of existing buildings. To this topic, the work presents all the research steps from the design process, through the experimental characterization in laboratory to the final on-site construction with respective monitoring campaign for the envelope retrofitting of an Italian residential building. The developed system, result of a European founded project EASEE is a prefabricated composite panel that integrate both thermal insulation and exterior finishing

development of a system for the production of disposable carbon fiber formworks

This article presents a new method for the production of disposable carbon fiber formworks for the casting of reinforced concrete columns. The desired three-dimensional object can be made by the robotic hot wire cutting of polystyrene, thus generating the shape around which the carbon fiber is deposited. The manufacturing technique is the so-called filament winding, where the polystyrene shape—obtained through hotwire cutting—is wrapped in fiber tape and then undergoes a curing process, which returns the carbon geometry in solid form. At the end of the process, the final piece of carbon is obtained by dissolving the positive polystyrene mold with a solvent. This gives rise to a production method capable of creating geometries that cannot be achieved by other means. The choice of creating disposable fiber formworks for concrete castings has considerable advantages: the possibility of creating structural elements with complex geometries that cannot be obtained by means of traditional formworks or other materials; saving of time in the casting phase and the advantage of not having the de-casting phase; facilitating the positioning of formworks and other structural elements thanks to the reduced weight of the material; the possibility of having always different geometries and a finish with a high aesthetic value and functional performance. The combination of concrete and carbon fibers offers above all considerable advantages from the structural point of view. The formwork not only has the function of giving shape to the finished element but also becomes a collaborator for static purposes. If used for pillars, the carbon fiber formwork has the function of a hoop, which makes it possible to obtain columns with the same static capacity but with lower sections and the elimination of the transversal reinforcement

Pressor responses to hyperventilation in elderly subjects differentiate essential from secondary hypertension

AbstractWe evaluated pressor responses to the hyperventilation test in elderly normotensive (n=43, mean age 82 ± 5 years) and elderly hypertensive subjects (n=45 with essential hypertension, mean age 82 ± 2 years, and n=49 with secondary hypertension, mean age 82 ± 3 years). Hyperventilation did not change blood pressure (BP) in normotensive and secondary hypertensive subjects, whereas it decreased BP in essential hypertensives. Hierarchical cluster analysis based on BP responses to hyperventilation disclosed three groups of subjects in each population: group 1 exhibited a reduction in BP (essential hypertensives: 76%), group 2 no change (normotensives: 70%, secondary hypertensives: 76%), and group 3 an increase (normotensives: 19%, essential hypertensives: 13%, secondary hypertensives: 14%). Ambulatory BP monitoring found significant differences in pressor daytime profiles of hypertensive patients according to pressor responses to hyperventilation showing wide fluctuations in group 1 and 3 patients. Interestingly, the peak ambulatory SBP values correlated to the pre-hyperventilation SBP values in group 1, and to the hyperventilation peak SBP values in group 3. In conclusion: 1) Aging decreases reactivity to respiratory alkalosis in elderly normotensives; 2) hyperventilation induces significant pressor changes frequently in essential hypertension, but rarely in secondary hypertension; 3) the significant pressor responses to hyperventilation reflect the daytime pressor profiles predicting the highest daily fluctuations of BP values

Internet-Based Birth-Cohort Studies: Is This the Future for Epidemiology?

BACKGROUND: International collaborative cohorts the NINFEA and the ELF studies are mother-child cohorts that use the internet for recruitment and follow-up of their members. The cohorts investigated the association of early life exposures and a wide range of non-communicable diseases. OBJECTIVE: The objective is to report the research methodology, with emphasis on the advantages and limitations offered by an Internet-based design. These studies were conducted in Turin, Italy and Wellington, New Zealand. METHODS: The cohorts utilized various online/offline methods to recruit participants. Pregnant women who became aware volunteered, completed an online questionnaire, thus obtaining baseline information. RESULTS: The NINFEA study has recruited 7003 pregnant women, while the ELF study has recruited 2197 women. The cohorts targeted the whole country, utilizing a range of support processes to reduce the attrition rate of the participants. For the NINFEA and ELF cohorts, online participants were predominantly older (35% and 28.9%, respectively), highly educated (55.6% and 84.9%, respectively), and were in their final trimester of pregnancy (48.5% and 53.6%, respectively). CONCLUSIONS: Internet-based cohort epidemiological studies are feasible, however, it is clear that participants are self-selective samples, as is the case for many birth cohorts. Internet-based cohort studies are potentially cost-effective and novel methodology for conducting long-term epidemiology research. However, from our experience, participants tend to be self-selective. In marked time, if the cohorts are to form part of a larger research program they require further use and exploration to address biases and overcome limitations
