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 ...

Neighbourhood morphology and solar irradiance in relation to urban climate

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

Assessing the relationship between neighbourhood morphology and urban climate is becoming increasingly important as cities continue to grow and the climate continues to change. Here we focus on the impact of (1) shapes and sizes of buildings, (2) street la ...

Effects of urban compactness on solar energy potential

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

Compactness is a major urban form parameter that affects the accessibility of solar energy in the built environment. Here we explore the relation between various compactness indicators and solar potential in the 16 neighbourhoods (11,418 buildings) constit ...

Ground temperature modelling: The case study of Rue des Maraîchers in Geneva

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Govinda Upadhyay

This paper presents a methodology to approximate the urban heat island effect by using a PostgreSQL database and CitySim software, a simulation tool to evaluate urban energy flows. A ground temperature model has been developed for shallow depths (until 4m) ...
