This paper presents a methodological approach to develop a user-oriented web tool to support the early stage of the decision making process for energy retrofitting of residential real estates. The tool mixes a simple analytical Urban Building Energy Model (UBEM) to user-oriented feedback interfaces to simulate the retrofitting potential of the residential units. The AUREE tool will be based on a Web – GIS GeoBlog portal with customized interfaces aimed to share the knowledge on urban building heritage and promote participation of stakeholders of the urban community. There are many literature exempla of guidelines or quality protocols on the topic of energy efficiency specified to particular types of buildings or focused on a territorial area, but these are generally not integrated into a geographically based tool. Moreover, the AUREE methodology aims to set interfaces that could use the portal users’ feedback to update the content of the portal itself. After touch on the theoretical context, a summary of the AUREE project is presented, and then the paper focuses on the structures of algorithms and tools adopted on the residential users’ interfaces. The interface mixes the results of an engineering Urban Building Energy Model based on local archetypal approach and standard energy calculation (series UNI 11300 - TS), with participative data provided via user-interactive interfaces to obtain customized retrofitting scenarios and suggestions. At the end of the paper, the main critical aspects and the further step of the research project are pointed

This paper presents a methodological approach to develop the tool “Urban Abacus of Building Energy performances (Abaco URbano Energetico degli Edifci – AUREE)” for supporting the renovation and energy efficiency enhancement of urban building heritage. The AUREE tool will be based on a Web – GIS GeoBlog portal with some customized interfaces aimed to share the knowledge on urban building heritage and promote the participation of the stakeholders of the urban community. The tool improves citizen and stakeholders awareness on building energy efficiency issues and facilitates the linkage between demand and offer for building companies services via the integration of two main elements: the first is a knowledge layer that represents the actual state of the energy performance of urban building heritage and the second is a spatial based Abacus of the more common building characteristics (structures, plants, uses, ..) and energy retrofitting and renovation technologies. After a touch on the theoretical context, this paper presents a summary of the AUREE general framework and focuses on the methodological approach of the Urban Abacus. The data structure integrates an Urban Building Energy Model (UBEM) in order to support on the energy retrofitting scenario analysis at the level of single building and also for a group of them (city block, district, city). At the end of the paper the furthers research steps have been pointed

Polycrystalline Sr2FeMoO6-δ specimens have been obtained by solid state synthesis from partially reduced SrFeO2,52 and SrMoO4 precursors. It has been shown that during oxygen desorption from the Sr2FeMoO6-δ compound in polythermal mode in a 5%H2/Ar gas flow at different heating rates, the oxygen index 6-δ depends on the heating rate and does not achieve saturation at T = 1420 K. Oxygen diffusion activation energy calculation using the Merzhanov method has shown that at an early stage of oxygen desorption from the Sr2FeMoO6-δ compound the oxygen diffusion activation energy is the lowest Еа = 76.7 kJ/mole at δ = 0.005. With an increase in the concentration of oxygen vacancies, the oxygen diffusion activation energy grows to Еа = 156.3 kJ/mole at δ = 0.06. It has been found that the dδ/dt = f (Т) and dδ/dt = f (δ) functions have a typical break which allows one to divide oxygen desorption in two process stages. It is hypothesized that an increase in the concentration of oxygen vacancies Vo•• leads to their mutual interaction followed by ordering in the Fe/Mo-01 crystallographic planes with the formation of various types of associations.

Purpose The purpose of this paper is to analyse a programme designed to welcome and train new employees, implemented in a chemical industry, privileging the transmission of know-how as a dynamic process where learning is co-constructed in the course of the activity. Design/methodology/approach The design of the programme was based on the analysis of the work performed in real context by operators and supervisors. The data about the programme’s evaluation were collected by questionnaire, assessing the trainees’ global development and the impact of the training programme (after six months). Findings This paper involves designing, planning and implementing “4 × 4 Training”, a training programme for young trainees. Combining in-class training with an extensive component of on-the-job mentoring, the programme involved trainees, mentors and internal trainers, monitored by work psychologists. The results show both the trainees and the mentors evaluate the programme positively. The professional transmission stands out as an activity that is thought through and defined in group, assisted by a mentoring relationship of mutual learning. Practical implications When planning and developing intergenerational transmission processes, it is crucial to consider the organisational conditions, to involve from an early stage the key players of each work situation and to guarantee that the mentoring activity and the productive activity overlap coherently. Originality/value It is an innovative process to integrate trainees in the chemical industry in Portugal. The methodological approach and the findings provide a first framework that justifies the relevance of the transmission of know-how through a real work situation.

Abstract We report the ability of an urban canopy model, coupled with a regional climate model, to simulate energy fluxes, the intra-urban variability of air temperature, urban-heat-island characteristics, indoor temperature variation, as well as anthropogenic heat emissions, in Berlin, Germany. A building energy model is implemented into the Double Canyon Effect Parametrization, which is coupled with the mesoscale climate model COSMO-CLM (COnsortium for Small-scale MOdelling in CLimate Mode) and takes into account heat generation within buildings and calculates the heat transfer between buildings and the urban atmosphere. The enhanced coupled urban model is applied in two simulations of 24-day duration for a winter and a summer period in 2018 in Berlin, using downscaled reanalysis data to a final grid spacing of 1 km. Model results are evaluated with observations of radiative and turbulent energy fluxes, 2-m air temperature, and indoor air temperature. The evaluation indicates that the improved model reproduces the diurnal characteristics of the observed turbulent heat fluxes, and considerably improves the simulated 2-m air temperature and urban heat island in winter, compared with the simulation without the building energy model. Our set-up also estimates the spatio–temporal variation of wintertime energy consumption due to heating with canyon geometry. The potential to save energy due to the urban heat island only becomes evident when comparing a suburban site with an urban site after applying the same grid-cell values for building and street widths. In summer, the model realistically reproduces the indoor air temperature and its temporal variation.
