Associated with rapid urbanization and escalation of bushfire events, Sydney has experienced significant air quality degradation in the XXI century. In this study, we present a 15-year retrospective analysis on the influence of individual meteorological factors on major air pollutants (NO2, O3, PM10 and PM2.5) at 14 different sites in Greater Sydney and Illawarra.

Cooling Cities – Advances in Urban Overheating and Mitigation Research

Abstract

This lecture aims to present and discuss recent research developments in the field of urban overheating, its impact on city life, and the development implementation and performance of advanced heat mitigation
studies to counterbalance the impact of increased urban temperatures. Recent results on the potential synergies between urban overheating and global climate change will be presented.

An innovative bioclimatic metric based on the Universal Thermal Climate Index (UTCI) is developed to quantify human thermal physiological heat stress. The Heat Stress Exposure (HSE) metric includes both duration and intensity dimensions of heat exposure, and in this paper it is applied to the Sydney Australia climatology. Geographic Information Systems (GIS) were used to spatially represent and visualize Sydney's HSE.

We assess the impact of advanced heat-mitigation technologies in a coastal temperate city under heatwave conditions. For the first time urban-heating mitigation scenarios that refer to ‘cool/reflective’ roofs and roads, ‘green/living’ roofs and shading by replacing low urban vegetation with deciduous broadleaf trees are considered at the highly dense-populated city of Athens (Greece). Numerical simulations are performed for a typical see-breeze and a heatwave day with the Weather Research and Forecasting (WRF) model coupled to an urban-canopy model.

Revailing weather conditions and urban morphology are among the fundamental drivers of the radiative and turbulent exchange processes that inherently result in an urban heat island (UHI). The influence of such drivers varies with temporal changes and must be estimated using recent and sufficiently large meteorological and land-use datasets.

Macroeconomic, demographic and climatic indicators for household electricity consumption model in Cyprus

By 2030 Cyprus committed to reduce greenhouse gas emissions by 40% and increase renewables’ energy share by 19% according to the European engagements. Difficulties appear due to the continuous increase in domestic energy consumption, the large dependency on fossil fuels and the adverse climate. A number of macroeconomic, demographic and climatic indicators that influence Cyprus’s electricity consumption (EC) was analysed for years 2000–2018 using augmented Dickey–Fuller unit root test and the autoregressive distributed lag model (ARDL). The ARDL model revealed that an increase in population could radically increase EC in the long-run and short-run. Results posit that a 1% increase in urban population, electricity price and unemployment decrease domestic EC in the long-run by 17.25%, 0.48% and 0.30%, respectively.

Combating climate change in an urban environment (Podcast by Global Greek Influence)

Mat Santamouris, the Anita Lawrence Professor of High-Performance Architecture at the University of New South Wales in Australia, is my guest this week.

Professor Santamouris discusses combating urban climate change through the synergy of research and perceptions, science and politics:
Enhancing communication of fragmented urban policies and activities between the different.
The measures to overcome energy poverty, a problem for developing and developed countries.
The positive integration of nanoscale photonics with quantum dots, as part of the tremendous revolution in material science.
