Multi-scale modeling of the urban meteorology: Integration of a new canopy model in the WRF model

Dasaraden Mauree, Alain Clappier

Urban parametrizations have been recently developed and integrated in mesoscale meteorological models for a better reproduction of urban heat islands and to compute building energy consumption. The objective of the present study is to evaluate the value of ...

Bioclimatic building design considering urban microclimate

Dasaraden Mauree

The urban context is often simplified or neglected in building energy models (BEM) due to their incapacity to consider accurately all heat fluxes provided from the environment. Simplifying too much the urban context can have consequences on the accuracy of ...

Evaluating Error Propagation in Coupled Land-Atmosphere Models

Dasaraden Mauree

This study examines how land-use errors from the Land Transformation Model (LTM) propagate through to climate as simulated by the Regional Atmospheric Model System (RAMS). The authors conducted five simulations of regional climate over East Africa: one usi ...

Local climate impact on the energy demand: an analysis at the European scale

Jean-Louis Scartezzini, Dasaraden Mauree, Silvia Coccolo, Amarasinghage Tharindu Dasun Perera, Cynthia Houmani

A reduction by 80% of the greenhouse gas emissions as well as a similar decrease for the final energy consumption is needed to respect the energy strategies and climate objectives at the European scale. To address this issue, we analysed the energy demand ...

Wind profile prediction in an urban canyon: a machine learning approach

Gianluca Mancini, Jean-Louis Scartezzini, Dasaraden Mauree, Roberto Castello

Resolving the wind profile in an urban canyon environment means dealing with the turbulent nature of the stream and the presence of non-negligible flux exchanges with the atmosphere inside the canopy, making any deterministic model solution computationally ...

Electrical hubs: An effective way to integrate non-dispatchable renewable energy sources with minimum impact to the grid

Jean-Louis Scartezzini, Dasaraden Mauree, Amarasinghage Tharindu Dasun Perera, Vahid Moussavi Nik

A paradigm change in energy system design tools, energy market, and energy policy is required to attain the target levels in renewable energy integration and in minimizing pollutant emissions in power generation. Integrating non-dispatchable renewable ener ...

Wavelet variance scale-dependence as a dynamics discriminating tool in high-frequency urban wind speed time series

Dasaraden Mauree, Fabian Guignard

High frequency wind time series measured at different heights from the ground (from 1.5 to 25.5 meters) in an urban area were investigated by using the variance of the coefficients of their wavelet transform. Two ranges of scales were identified, sensitive ...

How building energy models take the local climate into account in an urban context – A review

Dasaraden Mauree

The urban context is often simplified or neglected in Building Energy Models (BEMs) due to the difficulties of taking accurately into account all the heat fluxes emanating from the environment. Oversimplifying the urban context can impact the accuracy of t ...

Cooling potential of greening in the urban environment, a step further towards practice

Jean-Louis Scartezzini, Silvia Coccolo, Dasaraden Mauree, Jérôme Henri Kämpf

In the present century, for the first time in history, the urban population overpassed the rural one. Cities are growing, and their impact on the world energy balance is significant. Consequently, a sustainable urban environment focusing on the reduction o ...

Linearity versus non-linearity in high frequency multilevel wind time series measured in urban areas

Dasaraden Mauree, Fabian Guignard

In this paper, high frequency wind time series measured at different heights from the ground (from 5.5 to 25.5 meters) in an urban area were investigated. The spectrum of each series is characterized by a power-law behaviour at low frequency range, with a ...
