Abstract
This study investigates the energy-efficient building regulatory practices of 57 pertinent Global South (GS) countries and their current response to climate-change mitigation strategies in the built environment (BE). This thesis proposes developing a systemic decision-making tool to advise GS countries on efficient guidelines in the form of an interactive online platform (IOP). Various aspects of climate change, methods, mitigation and adaptation have been studied extensively in developed countries or the Global North (GN). In comparison, the current knowledge levels regarding energy efficiency, its associated codes and regulations in developing GS countries are limited. At the same time, most GS countries are more vulnerable than GN countries to the impact of climate change and the resultant effects caused by global warming.
In 2015, members of the United Nations (UN) adopted 17 Sustainable Development Goals (SDGs) and 169 associated climate-change targets as part of the 2030 Agenda for Sustainable Development. The SDGs include affordable and clean energy (SDG 7); developing sustainable cities and communities (SDG 11); ensuring sustainable infrastructure (SDG 9); and taking overall climate action (SDG 13). The original intention of the SDGs was to achieve a more sustainable future by addressing poverty levels, protecting the planet and safeguarding peace and prosperity for everyone. With less than seven years left to achieve the identified SDGs, it is improbable that GS countries will meet the agreed intergovernmental climate-change targets and achieve the SDGs.
The BE features directly in SDGs 9 and 11, and indirectly in SDGs 6, 7 and 13, which require a complete redevelopment of the building sector. A limited number of GS countries have sufficient Building Energy Efficiency Codes (BEECs) addressing the adverse effects of climate change. This knowledge gap requires urgent attention. Researchers and decision-makers must develop environmental knowledge and literacy to achieve long-term sustainable stratagems.
Focusing on the BE, this study reviews energy-efficiency’s history, concepts and role, from its original inception to existing practices and available frameworks. The study defines the GS, highlighting the significance, contribution and critical need for resource efficiency in its BE. Using the projected 2050 urban population figures, CO₂ emissions and distinctive climatic regions as a selection basis, the study identified the largest GS role players and evaluated the extent and efficacy of their current BEECs. The mixed-method research methodology includes a combination of literature review and desk research. Data originate from various government departments, official regulatory bodies and industry professionals. The data were standardised, evaluated and interpreted to develop the proposed new decision-making tool.
The results of the first research stage indicated that 49% of the selected GS countries are not implementing any form of BEECs or related policies. The study progressed to a critical review and analysis of country-specific BE policies to address the identified need for building energy-efficiency regulations in the GS. Variable-oriented comparisons of the energy-efficiency levels in present-day BE regulatory policies of GS countries provided the primary research data. The data were compared with specific sustainability criteria to develop a prototype decision-making tool. The information was translated into an innovative IOP, called the Sustainable Level Indicator Model, Matrix and Maps (SLIM³). The purpose of using an online platform for SLIM³ is to facilitate and enhance information accessibility. Decision-makers could use SLIM³ to establish guidelines and provide a way forward to facilitate more extensive implementation of BEECS and strategies within the GS.
The uniqueness of this study is threefold. Firstly, the study collated all the available BEECs’ data for the GS. Secondly, the research is presented comparatively to facilitate knowledge sharing. Thirdly, the contribution of SLIM³ as a digital information system addresses the limited research and information shortfall on BEECs, specifically in the GS.
This study is one of the first and most extensive research projects consolidating and comparing the BEECs of 57 GS countries. The SLIM³ tool aims to guide GS countries without the necessary codes towards BE resilience while moving closer to the SDGs and 2050 climate-change targets.
