Plants for Environmental Protection
2023
Plants for environmental protection are Anaerobic Digestion plants for converting biomass as Renewable Energy Source (RES), i.e. biowaste, agricultural feedstock, livestock effluents (manure and slurry) and food industry by-products, into biogas, i.e. bioenergy, as well as digestate, i.e. biofertiliser. In turn, biogas can be converted into electrical and thermal energy or can be used for extracting biomethane, i.e. biofuel, or can be injected in the natural gas grid. Moreover, digestate can be divided into solid and liquid fractions, that can be used for fertilisation or fertirrigation, respectively, sometimes after aerobic composting.
The overall classification of residential buildings: Possible role of tourist EU Ecolabel award scheme
2012
Abstract The debate on the environmental performance of buildings and their classification is continuously rising and deeply involves all actors of the sector, from researchers to technicians and from owners to real estate managers. In the field, the EU has created a panel that is currently working on defining the criteria for attributing an Ecolabel award to a building. However, despite the enormous efforts made by administrative and academic institutions, a suitable and widely available scheme for operators to assess the environmental performance of a building is far from being established. To help provide a solution to the problem, the possibility of adopting the EU Ecolabel scheme estab…
The Multilevel Model in the Computer-Generated Appraisal: A Case in Palermo
2017
The construction of a mass appraisal model requires the preliminary study of the real estate market, the sampling of sold properties, the development of a forecasting model and the verification of the appraisal results. They are generally computerised methods, that work with geo-referenced data. This experimental work has proceeded to build a mass appraisal model, collecting a data sample of sales of apartments in the city of Palermo, in the five years 2008–2012, using a multivariate statistical model (multilevel), testing the results and providing the operating applications in a scheme of online real estate valuations.
The evolution of the feudal income in the marquisate of Llombai (XVI-XIX centuries)
2006
Este artículo analiza la evolución de la renta feudal de un señorío valenciano particularmente bien documentado, el marquesado de Llombai, posesión de los duques de Gandía, en un período muy extenso que va de 1486 a 1819. Se estudia la renta nominal (tanto bruta como la neta, es decir la cantidad que percibía efectivamente el señor) y la renta real o deflactada, que es la más interesante, ya que tiene en cuenta el efecto de la evolución de los precios. Esta última muestra una tendencia a la baja durante el siglo XVI, lo que indica que no pudo resistir el efecto de la llamada revolución de los precios, una recuperación en el XVII, una vez superado el fuerte bache que supuso la expulsión de l…
Sustainable, circular and innovative value chains using growing substrata alternative to peat for the cultivation of nutraceutical species
2019
The modern agricultural system is wasteful, with Europe generating some 700 million tonnes of agricultural and food waste each year. In the context of the agri-food chain, the ‘circular economy’ aims to reduce waste while also making best use of the ‘wastes’ produced by using economically viable processes and procedures to increase their value. In this paper we will try to frame the key issues associated with food waste into the emerging bioeconomy and circular-economic mode, suggesting that these three concepts are intertwined, and considering them unitarily might provide win-win solutions that minimize wastage, promote income growth and job creation, and prompt sustainable local developme…
The urban rent in the multicultural city: retail shops, migrants and urban decline in the historic centre of Palermo
2020
La diffusione di nuove modalità di vendita al dettaglio, come gli shopping mall, i megastore e l’e-commerce, hanno modificato i tradizionali modelli localizzativi di immobili a destinazione commerciale, incidendo anche sulle connotazioni del tessuto urbano ed extraurbano e sulla distribuzione spaziale della rendita. Anche le zone centrali delle città hanno subito trasformazioni significative, che a volte si traducono in un vero e proprio declino, soprattutto in presenza di sistemi economici locali deboli e di mercati immobiliari in recessione. Una quota rilevante di immobili a destinazione commerciale può rimanere a lungo non utilizzata per eccesso di offerta sulla domanda, poiché a fronte …
The Expertise in the Real Estate Appraisal in Italy.
2014
The study focuses on real estate expertise in Italy considering: the market surface ratios, proposing a series of tests designed to predict the influence of these surfaces on the result of the valuation; and the coefficients of the not surface characteristics providing a measure of the estimation error induced by their use. Overall, the study aims to bring out on a rational level the deficiencies, inaccuracies and errors of the valuations based on the expertise when it is applied to the real estate market. In Italy the application of valuation standard is in the early stages of launching.
Multicultural Palermo between gentrification and real estate market crisis in the historical centre
2022
Multiculturalism is a characteristic of the post industrial city which will challenge planning through new paradigms, in fact the increasing of transnational flow of migrants reshapes the physical urban space and the socio-cultural relations, expressing new housing needs often neglected by planning and public policies. The essay discusses the experimental analysis conducted in an area of the historical centre of Palermo, where there is a high concentration of migrants in order to assess their potential involvement in the processes of residential gentrification, within the controversial panorama of urban regeneration policies, economic crisis and real estate market. The demographic dynamic, …
RAZIONALIZZAZIONE ESTIMATIVA DELL'EXPERTISE IMMOBILIARE
2013
The Italian appraisal practice is characterized by valuations developed in subjective opinions formulated by the valuers, according to the experience and the competence rather than on the survey of the market data of comparable properties. This practice makes up for the lack of information on the real estate market and to the consequent absence of systematic collections of market data. This tradition is in the cadastral appraisal for the rural (1886) and urban properties (1939). The assessed income is appraised for a representative property and wide to all the other properties with arbitrary scores (pure number). The assessed value is derived from the income with fixed multipliers.
The appraisal smoothing in the real estate indeces
2013
The appraisal smoothing is the phenomenon in which the valuation of a property, based on the judgments of appraisers (expertise) rather than on the collection of market data, is influenced by previous valuations performed by the same expert. The most obvious consequence of the exercise of expertise is the tendency to generate in the time a smoothing in the estimated value. This is the first experimental application of the appraisal smoothing theory in Italy. The general spread of real estate valuations, based on prices and average prices refer to a single commercial parameter (usually the surface), generates the natural suspicion that the smoothing effect could be widely disseminated and th…
