An overview of ecopreneurship, eco-innovation, and the ecological sector
2019
Given the current trend toward a more sustainable and environmentally-friendly economy, the overlap between entrepreneurship and sustainability has become a key research area. Part of this trend is the emergence of ecopreneurial businesses. These businesses are pioneers in using innovation to achieve sustainable growth by exploiting market opportunities. This article presents an overview of the concepts of ecopreneurship, eco-innovation, and the ecological sector. A rigorous review of the literature in this area is presented. The results of this review show the key values and principles that are central to this new stream of research and shed light on opportunities for further research. The…

From The Lisbon Strategy To Europe 2020
2015
Abstract The idea of a Western Europe economic recovery occurs after World War II. First as a common market, and later, after enlargement towards Central and Eastern Europe as the single internal market. Due to the new challenges with which the global economy was faced, the longterm and short-term European economy needs a coherent growth economic strategy; the success of this strategy depends on joint action. Expanding the European economy is a continuous and irreversible process, yet it advances too slowly. The Lisbon strategy is a commitment to revive the European economy in all sectors. At 5 years after implementation of this strategy it was found that the results are insufficient, so me…
FULL PAPER: Earth for social housing in Palestine: an alternative for a sustainable refurbishment of building’s envelopes
2016
The suitable climates in the cities of Jericho and Gaza boosted the emergence of new attempts to revive earthen architecture on organizational and individual levels. These attempts produced a number of earthen buildings in the last few years following the crucial need to find alternative low cost material instead of natural stone, which is used in a large scale in Palestine. Similar attempts had a certain response to the social needs and economic situation there. This paper focuses on the possibility of using earth as an alternative material to refurbish the envelopes of existing housing units including two categories; firstly, refurbishing envelopes of housing units those were partially de…
Evaluating the thermal-radiative performance of ENVI-met model for green infrastructure typologies: Experience from a subtropical climate
2022
Abstract Microclimate knowledge has been intensively integrated into urban planning and design to improve the buildings’ energy performance and outdoor thermal comfort. To assess the climatic mitigation strategies, numerical modeling is gaining higher relevance. ENVI-met, a microclimate model to simulate the complex surface-vegetation-atmosphere interactions in the built environment, is receiving increasing popularity. This study aims to systematically evaluate the thermal-radiative performance of the ENVI-met model based on its recent updates. First, a field measurement was conducted in a subtropical city. Thermal-radiative parameters were collected besides three green infrastructure (GI) …
The miniaturised emission chamber system and home-made passive flux sampler studies of monoaromatic hydrocarbons emissions from selected commercially…
2017
Abstract The estimation of the emission rate of organic compounds released from various types of indoor materials can be performed using stationary environmental test chambers (ETC) classified as ex-situ methods or small-scale portable analytical devices based on the use of passive technique at the stage of analytes sampling from the gaseous phase (in-situ methods). The paper presents results of emissions of selected organic compounds from the monoaromatic hydrocarbons group (benzene, toluene, ethylbenzene, p,m-xylene and styrene) emitted from the surfaces of various types of commercially-available floor coverings and the underlay made of polyurethane foam which might be installed indoors u…
Vapour condensation and moisture accumulation in porous building wall
2002
Simultaneous one-dimensional heat and vapour transfer with condensation in a porous wall is analytically investigated. Spatially steady-state distribution of accumulated moisture, less than the critical content, is described. Closed-form analytical expressions for the temperature, condensation rate and moisture content are obtained. The presented model requires material properties which are relatively simple and easy to determine. The results of the paper are illustrated with an example of multilayer building wall under climatic conditions.
An optimal dimensioning method of a green wall structure for noise pollution reduction
2021
International audience; This paper concern the optimization of a multilayered green wall structure including substrate and foliage in order to reduce as much as possible backward noise reflection and forward transmission from the wall. Each component involved in the wall structure is fully characterized experimentally to get its transfer matrix. Simulation demonstrated that foliage layer superimposed to substrate layer doesn’t affect the transmission losses but contributes greatly to the increase of return losses of the green wall structure. To achieve the best performances in terms of return and forward losses as well as frequency bandwidth, the methods of optimization are discussed inclu…
Analysis of the chemical and microstructural modifications effects on the hydro-mechanical behaviour of a lime-treated clay
2019
The paper presents the results of a characterization of kinetic characteristics of pozzolanic reaction with the aim to investigate the time-dependent modification of clay properties as a consequence of mixing with lime. Results of chemical analyses are in agreement with the increase of mechanical properties and with the observed microstructure modifications up to one year of curing time. The rate of development of pozzolanic reactions seems to be almost constant while the time required for their completion is dependent on the lime content. Pozzolanic products are responsible for the time reduction of swelling strain upon saturation as well as for the increases of yielding stress, stiffness …
Evaluation of a microclimate model for predicting the thermal behavior of different ground surfaces
2013
The microclimate model ENVI-met Version 4 was evaluated with field data in terms of the thermal behavior of different types of ground surface. A field experiment was conducted in a real construction project in Guangzhou, South China, from 29 August to 2 September in 2010. The surface types of concrete, tile, asphalt and grass were investigated. The comparison between observation and prediction was performed for both sub- and above-surface variables, including soil temperature at different depths, soil heat flux at the surface, surface temperature, and air temperature and humidity at different heights. The results show that the ENVI-met model is capable of reasonably modelling the diurnal th…
