Vegetation growth parameters and leaf temperature: Experimental results from a six plots green roofs' system
2016
Abstract The paper provides a contribution for populating database of three physical parameters needed to model energy performance of buildings with green roofs: “coverage ratio” ( σ f ), leaf area index (LAI) and leaf temperature ( T f ). On purpose, six plant species were investigated experimentally: Phyla nordiflora, Aptenia lancifolia , Mesembryanthenum barbatus , Gazania nivea, Gazania uniflora , and Sedum . Proper ranges of the cited parameters have been found for each species. The here indicated ranges of σ f values refer to different growth levels of the species in the same lapse of time, that is four months. Single measured LAI values are also reported for the same plants. As for t…
Economic impact of BACS and TBM systems on residential buildings
2013
The paper presents the results of a study on the economic impact of building automation control systems and technical building management systems on residential buildings. The different functions considered by European Standard EN 15232 and having impact on the energy performance of buildings are applied to a test house, varying its energy efficiency class. The economic impact due to the introduction of each BACS or TBM function is evaluated using the BAC factors method, considering the real costs for the purchase and the installation of the components that implement the specific functions and the yearly energy costs of the building before and after their installation.
Simulation and visualization of thermal metaphors in a virtual environment for thermal building assessment
2014
International audience; The current application of the design process through energy efficiency in virtual reality (VR) systems is limited mostly to building performance predictions and design review, as the issue of the data formats and the workflow used for 3D modeling, thermal calculation and VR visualization. The importance of energy efficiency and integration of advances in building design and VR technology have lead this research to focus on thermal simulation results visualized in a virtual environment to optimize building design, particularly concerning heritage buildings. The emphasis is on the perception of thermal data of a room simulated in a virtual environment (VE) in order to…

Marketing strategy, social responsibility, and value chain in the agri-food system
2020
The agri-food sector has changed significantly over the years, moving from a simple production system to a more and more industrialized one. For agents/operators involved in this sector, ensuring product quality and environmental externalities has become the key point to gaining a competitive advantage. In this context, corporate social responsibility (CSR) fits perfectly. This study analyzes the influence of CSR practices on the economic performance of a random sample of 130 agri-food companies in Italy. The results of an analysis of multiple linear regression models show that the economic performance (measured through value added and income) of agri-food enterprises seems to be influenced…
La partecipazione ad un business ecosystem: implicazioni per la nozione di successo
2020
L’obiettivo del capitolo è offrire un’introduzione alla letteratura sugli ecosistemi aziendali e discutere critica-mente la tematica del successo e della misurazione delle performance del business ecosystem e degli attori che vi partecipano. A tale scopo, il capitolo è strutturato come segue. Il paragrafo 2 focalizza l’attenzione sulla definizione di business ecosystem. I paragrafi 3, 4 e 5 spiegano, rispettivamente, perché nasce un business ecosystem, chi sono gli attori e quali sono le strutture sottese agli ecosistemi aziendali. Il paragrafo 6 discute la misurazione delle performance del business ecosystem focalizzando l’attenzione sui seguenti aspetti: (a) indicatori di performance a li…
New evidence on accelerator performance based on funding and location
2020
Seed accelerators (SAs) appear as a more advanced version of business incubators. These for-profit organizations in exchange of equity, help setting new start-ups by providing mentoring and funding during its first months. Due to their emergent nature, the impact and expectations of SAs remains largely unknown. Therefore, the purpose of this study is to throw new light on this field by empirically assessing for the first time the performance and prospects of these organizations through a survey of 116 SAs.,A model based on the Business Incubators literature is built with four categories covering size, location, age and profitability variables, leading to two hypotheses to be tested empirica…
Executive remuneration determinants: New evidence from meta-analysis
2019
This meta-analysis takes stock of 121 C.E.O. pay studies published between 1998 and 2018 with the objective of identifying the main drivers of C.E.O. pay from a global perspective and contributing to the agency vs managerial debate on this ground. The meta-results disclose a positive C.E.O. pay–performance correlation (the highest correlation coefficient corresponds to Earnings per share with a 34%) as the agency theory prescribes and the governance policies promote. However, firm size still predominates as the main driver of C.E.O. pay (correlation coefficient is around 44%) according to managerial premises. Moreover, our results reconcile both approaches because results of the meta-regres…
