Article
Understanding and managing hydrological and microclimate conditions is needed for the adap-tation of our cities to global warming. Evapotranspiration, or latent heat flux, plays a key role in heat mitigation strategies. Its modelling, as the modelling of its impact on the urban microcli-mate, remains a scientific challenge, especially during hot peri...
Chapter
The SOLENE-microclimat model has been developed to investigate the consequences of urban context on local microclimate and indoor thermal conditions. It is dedicated to modeling urban microclimate and building thermal behavior at the district scale. The modeling approach is based on the coupling of several modules: radiative, thermal, and CFD model...

Shelters used to protect air temperature sensors from solar radiation induce a measurement error. This work presents a semi-empirical model based on meteorological variables to evaluate this error. The model equation is based on the analytical solution of a simplified energy balance performed on a naturally ventilated shelter. Two main physical err...
Article
In a dense urban area, pavement watering could be a solution to mitigate the Urban Heat Island. So far, mainly experimental studies have been used to evaluate watering techniques. In this study, a soil model dedicated to pavement watering has been developed within the urban climate model SOLENE-microclimat. This watering model is presented and eval...

Green areas induce smaller increases in the air temperature than built-up areas. They can offer a solution to mitigating the urban heat island impacts during heat waves, since the cool air generated by a park is diffused into its immediate surroundings through forced or natural convection. The purpose of this study is to characterize the effect of...
Article
Full-text available
Nowadays, the study of the outside thermal comfort is more and more taking into consideration in the urban design process. In a climate change context, town planners have to find solutions to mitigate the effects of the global warming and to ensure that outside spaces designed in new districts will remain liveable.
Article
Full-text available
A full coupling between a CFD code, a thermo-radiative model and a building energy simulation model enables Solene-microclimat software to calculate both building thermal behavior and urban microclimate with the retroaction of buildings on microclimate. However, this full coupling is time consuming and it is legitimate to wonder if it is always nec...
Article
The main purpose of this study is to evaluate an urban soil model that will accurately reproduce the heat flux into urban soil, which has an influence on the urban heat island effect, for typical urban land use such as a car park. After a complete literature review, a sensitivity study is carried out on a large number of parameters: material proper...
Article
Full-text available
The Town Energy Balance (TEB) model has been refined and improved in order to explicitly represent street trees and their impacts on radiative transfer: a new vegetated stratum on the vertical plane, which can shade the road, the walls, and the low vegetation has been added. This modification led to more complex radiative calculations, but has been...

The TEB model has been refined and improved in order to explicitly represent street trees and their impacts on radiative transfers: a new vegetated stratum on the vertical plane, which can superimpose to road and low vegetation has been added. This modification has obviously complexified the radiative calculations, but has been done with a concern...
Article
Abstract The urban population rise leads town planners to increase the building density in order to avoid an urban sprawl what can induce higher risks of the heat island occurrence and increases buildings needs for air conditioning. Urban vegetation such as trees, grass areas, green walls and roofs can be a solution to mitigate it. The aim of the s...
Article
Full-text available
The building simulation tools available to evaluate energy consumption are numerous. Nevertheless, the main lack of the majority of these tools is the ability of consider the environment where the studied building is. Moreover, some of them impose strong constraints such as the choice of walls composition limited to several predefined walls or the...
Article
Given the current need for a comprehensive understanding of the consequences of urban development to achieve the goal of sustainable cities, knowledge of urban microclimates is essential to control the UHI effect, conduct urban amenity studies and monitor energy consumption. Modeling offers a way for enhancing this knowledge and it also constitutes...
Article
Humidity and temperature are key factors in greenhouse climate management since they impact crop growth. For example, under high humidity and low temperatures, condensation may occur and lead to crop damage. In order to assess the condensation mechanism inside a closed greenhouse during the night, a closed monospan 100-m2 Venlo glasshouse was consi...

Thus, representing the interactions between physical p...

This paper aims at giving a synthetic view of the different works related to urban climate, thermal comfort and building energy consumption produced within the 4-years work on VegDUD project funded by the French National Research Agency and wherein more than 50 researchers were involved. From the building to the city scale, we studied the impacts o...
Article
Assessing the distribution of short wavelength radiation inside a greenhouse crop is of prime interest as absorbed radiation is one of the main factors governing the energy and water vapour transfers at plant level. The aim of this paper is to analyse the distribution of solar radiation inside an ornamental crop and to improve the crop submodel imp...
Article
The aim of this study is to implement an unsteady 2D CFD model to predict the time-evolution of greenhouse temperature and humidity distributions all night long in winter, taking account of both radiative transfers and crop interactions with the inside climate. Beyond the classical conservation equations, specific radiativeand crop-submodels were a...
Article
Reducing water consumption in greenhouses is one of the main concerns for growers. This implies better knowledge of the transpiration process in order to adapt water inputs to plant needs. Several simple models have been developed to estimate transpiration. The Penman–Monteith (PM) model and the Direct Method (DM) model are two of the most widespre...

The objectives of this thesis are to develop a numerical tool which would be able to provide exhaustive information on the evolution of the distributed climate in a greenhouse. The thesis is based on experimental and numerical approaches and aims for giving information on the main concerns of the growers: the temperature and the humidity management...
Article
Following the rise of energy costs and fuel scarcity, energy becomes today one of the main greenhouse crop production expenses. In this context, growers have to adapt their production system and climate management strategy in order to remain competitive, particularly at night when heat supply is often required and risk of condensation is enhanced....
Article
The crop activity inside a greenhouse is strongly affected by the local microclimatic conditions (radiation, temperature and humidity of air in particular). In order to reduce the consumption of energy and water, the control of these parameters is of prime interest. A better knowledge of the local climate may also help to formalize processes in CFD...
Article
Les serres de production horticole sont utilisées pour soustraire les cultures aux contraintes climatiques extérieures afin de gérer au mieux les besoins des plantes, accélérer leur croissance et produire tout au long de l’année. Dans le contexte actuel de crise énergétique à laquelle se superpose une crise sanitaire sur fond de montée en puissance...
Article
In order to improve crop quality and reduce consumption of water, energy and fertilizer in greenhouses, it is crucial to have a precise knowledge of the internal distributed climate. During the day, because of the path of the sun, there are important variations in the amount of solar radiation reaching the crop, which strongly impacts climate and t...
