Abstract
ABSTRACT In urban sustainability, passive cooling energy systems are recognised as primary design factors that highlight efficient and performative buildings. In the literature, there is a gap in addressing these design systems in the form of strategies that holistically suggest sustainable energy systems, cleaner built environments, and urban sustainability. This study fills this gap by conducting a comprehensive SWOT analysis of all major passive cooling energy systems. In doing so, the study highlights key implications from a multi-indicator perspective comprised of five primary indicators, ‘energy’, ‘policy’, ‘practice’, ‘health’, and ‘environment’. These indicators are significant for disciplines of sustainable energy systems and the built environment. Through an in-depth interdependency evaluation of these indicators, this study assesses the passive energy systems across three spatial levels of macro, meso, and micro. Finally, this paper provides a holistic overview of these sustainable energy systems from the policy and practice perspectives across the three spatial levels.
Highlights
Buildings are noted to be major contributors to energy consumption in the 21st century (Chenari et al 2016)
This study offers a set of comprehensive SWOT analyses of passive cooling energy systems at three spatial levels of macro, meso and micro
We can argue in favour of meso and micro scales for the benefit of energy indicators and towards energy-use reductions. This is significant for cooling, which is the main focus of this research study (Dawodu and Cheshmehzangi, 2017). It is well established within this research study the positive impact of utilizing passive ventilation in cooling strategies, especially within hotter climate zones
Summary
Buildings are noted to be major contributors to energy consumption in the 21st century (Chenari et al 2016). Large energy consumption, shortage in conventional sources of energy and escalating energy prices has prompted the revaluation of airconditioning, HVACs and general design practices This has led to the application of passive energy design techniques (energy efficient design) in the built environment (BE) to reduce energy consumption, improve thermal comfort and health, all the while considering the environmental impacts (Geetha and Velraj 2012). This view of passive design in buildings stretches far beyond buildings and considers the entire urban environment from a neighbourhood scale (Meso level) to city scale (Macro level)
