A machine learning approach for mapping the very shallow theoretical geothermal potential

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni, Dan Assouline

The very shallow geothermal potential (vSGP) is increasingly recognized as a viable resource for providing clean thermal energy in urban and rural areas. This is primarily due to its reliability, low-cost installation, easy maintenance, and little constrai ...

Statistical-thermodynamics modelling of the built environment in relation to urban ecology

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni

Various aspects of the built environment have important effects on ecology. Providing suitable metrics for the built forms so as to quantify and model their internal relations and external ecological footprints, however, remains a challenge. Here we provid ...

A solar-based sustainable urban design: The effects of city-scale street-canyon geometry on solar access in Geneva, Switzerland

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Nahid Mohajeri Pour Rayeni, Dan Assouline

Buildings commonly have the largest share in the energy demand of a country, but they also offer sites for the generation of solar energy. Here we develop a methodology to analyse the effects of street-canyon geometries on the solar access of street surfac ...

Visualizing street orientation and solar radiation in relation to complex topography

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Nahid Mohajeri Pour Rayeni

Street networks can be visualized in various ways depending on the purpose. Here we introduce (in the present context) a new technique for visualizing the orientation of street networks in relation to complex topography. The technique is tested on the city ...

Quantifying the Differences in Geometry and Size Distributions of Buildings Within Cities

Nahid Mohajeri Pour Rayeni

There have been many studies on the spatial configuration of cities, but few attempts to quantify the difference in building patterns between the old and new parts of cities. This may be partly attributable to lack of suitable study methods. This paper pre ...

Dike emplacement at Bardarbunga, Iceland, induces unusual stress changes, caldera deformation, and earthquakes

Nahid Mohajeri Pour Rayeni

A 45-km-long regional dike was emplaced over a period of 2 weeks in August 2014 at the boundary between the East and North Volcanic Zones in Iceland. This is the first regional dike emplacement in Iceland monitored with modern geophysical networks, the imp ...

A city-scale roof shape classification using machine learning for solar energy applications

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni, Dan Assouline

Solar energy deployment through PV installations in urban areas depends strongly on the shape, size, and orientation of available roofs. Here we use a machine learning approach, Support Vector Machine (SVM) classification, to classify 10,085 building roofs ...

Urban greening archetypes at the European scale

Jean-Louis Scartezzini, Silvia Coccolo, Dasaraden Mauree, Amarasinghage Tharindu Dasun Perera, Nahid Mohajeri Pour Rayeni, Cynthia Houmani

Urban greening has great ecological, social and economic benefits for the built environment. It also has significant impacts on the microclimate and urban energy balance. In this study, we quantify the impacts of urban greening on the ground surface temper ...

CO2 emissions in relation to street-network configuration and city size

Nahid Mohajeri Pour Rayeni

The street-network efficiency of tens of British cities in relation to transport fuel consumption and CO2 emissions are analyzed. The results show a strong linear positive correlation between length entropy and average street length, and a negative correla ...

Big data mining for the estimation of hourly rooftop photovoltaic potential and its uncertainty

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni, Roberto Castello, Alina Ursula Rosa Walch

The large-scale deployment of photovoltaics (PV) on building rooftops can play a significant role in the transition to a low-carbon energy system. To date, the lack of high-resolution building and environmental data and the large uncertainties related to e ...

How green are British cities? Scaling relations and CO2 emissions

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni

How green or environmentally friendly urban areas are in comparison with rural areas is a topic that has received much attention in recent years. This is understandable because urban areas already emit around 70% of the global greenhouse gases. This percen ...

How street canyon configuration control the accessibility of solar energy potential: Implication for urban design

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Nahid Mohajeri Pour Rayeni, Dan Assouline, Govinda Upadhyay

While the effects of street-canyon configuration on temperature, wind speed and direction, and air quality have received much attention, its impact on solar energy potential has not been much studied. This paper focuses on two aspects of the street-canyon ...

Improving the energy sustainability of a Swiss village through building renovation and renewable energy integration

Jean-Louis Scartezzini, Silvia Coccolo, Amarasinghage Tharindu Dasun Perera, Nahid Mohajeri Pour Rayeni, Lucas Mosca

The integration of renewable energy technologies and building renovation are the two main procedures for improving energy sustainability of buildings at neighborhood scale. It is difficult, however, to optimize these procedures simultaneously. This study f ...

Combining Fourier Analysis And Machine Learning To Estimate The Shallow-Ground Thermal Diffusivity In Switzerland

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni, Dan Assouline

We propose a methodology combining physical modelling and machine learning (ML) to estimate the apparent ground thermal diffusivity at the scale of a country. Based on ground temperature time series at different depths, we estimate the diffusivity at 49 Sw ...

Analysing and modelling the growth and efficiency of urban transportation infrastructures

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni

The total population of the United Kingdom is expected to increase from 63 million in 2011 to 73 million people in 2037. This is an increase by 16% in 26 years, which puts the urban infrastructure, particularly the transportation infrastructure, under grea ...
