    Abstract Although evolutionary algorithms coupled with building simulation codes are often applied in academic research, this approach has a limited use for actual applications of building design due to the high number of expensive simulation runs. The use of a surrogate model can overcome this issue.In the literature there are several functional approximation models that can emulate the building simulation during the optimization, thus increasing the process efficiency. However, there are no evidence-based studies comparing the performances of these methods for the building design optimization.This study compares the efficiency, the efficacy and the quality of the Pareto solutions obtained by Polynomial, Kriging (GRFM), Radial-basis function networks (RBFN), Multivariate Adaptive Regression Splines (MARS) and support vector machines (SVM) functional approximations. The test bed of the comparison is the evaluation of the optimal refurbishment of three reference buildings for which the actual Pareto front is also obtained through a brute-force approach.The results show that the MARS method outperforms the other surrogate models both in terms of efficiency and effectiveness, and also by assessing the quality of the Pareto front.

    Abstract Most of the developed countries are struggling to reduce carbon emissions into the atmosphere to meet the international agreements. One of the strategies to reduce climate change impacts is the decarbonisation of the electricity production: generation mixes are more and more based on renewable energy sources that are replacing the traditional fossil fuels.The effect of the electricity decarbonisation production reflects in the life cycle impacts of buildings, particularly if they are strongly dependent on the electrical energy as the main energy vector. The traditional Life Cycle Assessment (LCA) cannot capture the effect of lowering emission factors for electricity generation since only static values are considered. Moreover, also the grid-building interaction should be properly taken into account in the life cycle assessment of buildings using dynamic calculations. A dynamic life cycle analysis is the methodology that can overcome these limitations through the introduction of dynamic parameters within the life cycle inventory and in the life cycle impact assessment stages.A Dynamic Life Cycle Assessment (DLCA) is proposed in order to evaluate the consequences of electricity decarbonisation on the LCA of an “all electric” Nearly Zero Energy Building (NZEB). A comparison with literature results about similar constructions is finally provided.

    Abstract In the present work an equilibrium model (gas-solid), based on the minimization of the Gibbs energy, has been used in order to estimate the theoretical yield and the equilibrium composition of the reaction products (syngas and char) of biomass thermochemical conversion processes (pyrolysis and gasification). The data obtained from this model have also been used to calculate the heating value of the fuel gas, in order to evaluate the overall energy efficiency of the thermal conversion stage. The proposed model has been applied both to partial oxidation and steam gasification processes with varying air to biomass (ER) and steam to carbon (SC) ratio values and using different feedstocks; the obtained results have been compared with experimental data and with other model predictions obtaining a satisfactory agreement.

    Abstract In gas turbine cooling design, techniques for heat extraction from the surfaces exposed to the hot stream are based on the increase of the inner heat transfer areas and on the promotion of the turbulence of the cooling flow. This is currently obtained by casting periodic ribs on one or more sides of the serpentine passages into the core of the blade. Fluid dynamic and thermal behaviour of the cooling flow have been extensively investigated by means of experimental facilities and many papers dealing with this subject have appeared in the latest years. The evaluation of the average value of the heat transfer coefficient most of the time is inferred from local measurements obtained by various experimental techniques. Moreover the great majority of these studies are not concerned with the overall average heat transfer coefficient for the combined ribs and region between them, but do focus just on one of them. This paper presents an attempt to collect information about the average Nusselt number inside a straight ribbed duct. Series of measurements have been performed in steady state eliminating the error sources inherently connected with transient methods. A low speed wind tunnel, operating in steady state flow, has been built to simulate the actual flow condition occurring in a rectilinear blade cooling channel. A straight square channel with 20 transverse ribs on two sides has been tested for Re of about 3 x 10(4), 4.5 x 10(4) and 6 x 10(4). The ribbed wall test section is electrically heated and the heat removed by a stationary flow of known thermal and fluid dynamic characteristics.

    Title translation Findings on smoking habits in Valle dell'Agno. (U.L.S.S. no. 7 of the Veneto region).
    Abstract A study regarding te habit of smoking of the population of this area was accomplished by use of questionnaire completed by students of the local high schools. The study included 7279 subjects subdivided as follow: 1776 fathers, 1815 mothers and 3688 students/workers of age 12 years and older. Results regarding the parent group showed that 51,91% of the fathers and 21,65% of the mothers were smokers. Only the mother group showed a correlation of smoking with various levels of education and occupation. Results regarding the younger age groups revealed, in age range 12-14 years, a positive history of smoking in 8,12% of males and 7,61% of females; this incidence increased to 53,76% and 36,44% respectively by age 25 years. Occupation categories and smoking parents as an incentive element showed relationships with smoking. A progressively increasing incidence of smoking at an increasingly earlier age with greater involvement of females was shown in this study. However, the smoking incidence in our area is less than that in other areas of the Veneto probably because of local geographic and economic factors.

    Abstract Under the conditions used in this trial, the central membrane press showed a number of performance advantages over the side membrane unit. More juice was extracted per tonne of grapes. The juice was extracted faster and had lower phenol and at least equivalent browning levels. These attributes can all make an important contribution to improving winery cost effectiveness, process efficiency and product quality. [D 332] (Auth. abstract)
