No full textATENEA4SME: Industrial SME Self-Evaluation of Energy Efficiency
No full textPromoting energy efficiency in the Italian production sector is significantly hampered by the lack of knowledge, the scarcity and the limited distribution of tools for supporting energy audits in small and medium-sized enterprises (SMEs) in a wide range of Italian economic sectors (industry, tertiary sector, transport). The Advanced Tool for ENErgy Audit for SMEs, ATENEA4SME, is intended to help SMEs promote energy-efficiency projects, supports energy audits and self-evaluation of energy consumption. The tool uses an original mathematical model that takes into account the results of questionnaires and a multi-criteria analysis to generate recommendations for energy efficiency investments. This article will give a thorough explanation of the tool, emphasizing and outlining the sections as well as the procedures to get the ultimate summary of the energy usage of the enterprises under investigation and the potential for energy saving. From a technological and financial perspective, the tool helps to remove obstacles to the development of energy-efficiency measures. In this article, the IT and methodological structure of the tool will therefore be extensively described, and its operation for the context of SMEs will be illustrated, with application cases. Ample space will be allocated to the dissemination campaign and the replicability of the tool for all economic sectors of the industrial and tertiary sectors
Multidisciplinary approach to analyse historical water infrastructure and urban transformations: the case study of the Grabiglione Barisano in the Sassi of Matera, Italy
No full textThe historical urban fabrics are the evidence of traditional knowledge and practices generated by urbanization processes that take
advantage of the morphological characteristics of the territory. In the past, Matera represented an emblematic example of “smart
city”, in which the urban transformations impacted on the natural environment ensuring the ecosystem balance through the creation
of a complex water infrastructures network. The most recent urban expansions occurred into the historical districts of the Sassi of
Matera and their surrounding areas have led to the alteration of the “urban metabolism”, causing dangerous consequences as
uncontrolled surface runoff of rainwater and flooding. For these reasons, this study proposes innovative methodological approaches
which can guide the development of sustainable solutions capable of preserving the built landscapes. This study analyses the
transformations produced on the historical water infrastructure of the Grabiglione Barisano over time e the effects of these changes
on the Sasso Barisano urban context, developing the process within the environmental unit of the “watershed” through
an hydromorphic approach. The analysis of urban transformations within the watersheds allows us to understand the interrelations
between urban fabric and hydromorphic characteristics of the territorial context, overcoming the usual sectoral scientific approaches
that analyse separately the different fields of urban planning, architecture and hydrology. This approach highlights how the
construction activity conducted outside the perimeter of the Sasso Barisano watershed, apparently totally independent, has instead
influenced the way in which rainwater acts into this historical urban fabric. This contribution proposes an integrated workflow that
lays the foundations necessary for further research on the recovery and enhancement of this heritage, but which is reproducible for
other case studies
STRATEGIE DI RIGENERAZIONE URBANA E SPAZI RITROVATI: L’ESPERIENZA DEL QUARTIERE VERDERUOLO A POTENZA
No full textThe progressive degradation of urban public space, exacerbated by a car-centric vision of mobility and increasing land consumption, has compromised the quality of life in many residential neighborhoods. This
study aims to examine urban regeneration strategies that prioritize sustainability, environmental resilience, and the centrality of the human being within spatial dynamics. Through the case study of a public housing neighborhood characterized by various critical issues but also significant potential, the Verderuolo district in Potenza, this contribution proposes a replicable intervention model. The approach is based on the widespread redevelopment of public spaces, the promotion of active and sustainable mobility, and the restoration and expansion of green areas as places of social interaction and well-being. Integrating theoretical reflection, urban analysis, and design proposals, this work seeks to contribute to the ongoing discourse on how to restore meaning, functionality, and quality to urban space, placing both people and the environment at the core of every transformation process
Updates to 4.3um CO2 NLTE modeling for nadir hyperspectral infrared sounders
No full textModels for the exchange of radiant energy inside Earth’s atmosphere require knowledge of the excitation temperatures of
the emitting energy levels of the atmospheric components. In the lower atmosphere where collisions are frequent, we can
safely assume all vibrational levels for all molecules are in Local Thermodynamic Equilibrium (LTE). This is not
necessarily true in the upper atmosphere where density is lower and therefore fewer collisions. Lack of knowledge of, or
incorrect assumptions about, the upper atmosphere vibrational temperatures for channels whose weighting functions peak
high in the atmosphere will impact the accuracy of the modelled top-of-atmosphere radiances. An example is the CO2 4.3
μm (2250-2400 cm-1) bands, which upper states preferentially absorb solar radiation and are therefore in Non-Local
Thermodynamic Equilibrium (NLTE). For the current generation of hyperspectral sounders, the effect on observed
brightness temperature is on average 8-10 K and can significantly impact the kinetic temperature sounding. In this work
we present a comparison between different models in computing NLTE effects. Starting from a very recent set of
vibrational temperatures computed for CO2, which includes refinements to the effects of O3 and O collisions on CO2
vibrational temperatures, we have generated synthetic radiances with two different line-by-line models: kCARTA and
LBLRTM. With these two models, multiple simulations have been performed across different atmospheric states to capture
latitudinal variations and solar angle dependencies. For each atmospheric state, we have computed synthetic convolved
monochromatic radiances with and without NLTE effects. The differences between the two results have been parametrized
in terms of multiple variables and have been implemented, in different ways, in two fast radiative transfer models: σ-
IASI/F2N, implemented by University of Basilicata and under developments in the Italian Space Agency FIT-FORUM
project, and SARTA, developed at University of Maryland, Baltimore County. In this work, we will show how this fast
parameterization is capable of modeling the 4.3 μm spectral radiances compared to accurate line-by-line models
