Abstract

Globally, buildings are responsible for around 32% of energy consumption and 34% of greenhouse gas emissions. One reason for this is the poor energy efficiency of much of the current building stock. Around 75% of today’s buildings are projected to still be in use in 2050, highlighting the importance of retrofitting existing buildings for energy efficiency. Such a strategy presents substantial opportunities to decrease global energy consumption and greenhouse gas emissions. While building retrofit projects have been implemented in many developed countries, studies in hot-humid climates and developing countries are still lacking. The challenges posed by hot-humid climates make developing the right energy retrofit strategies even more difficult. This study reviews and analyses previous energy retrofit studies and optimisations in building energy retrofit that used multi-objective optimisation methods, especially in hot-humid climate regions, using a bibliometric mapping tool called “VOSviewer” (version 1.6.20). The study also follows the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework for systematic reviews. This literature review highlights the paucity of research related to Multi-Objective Optimisation building-energy retrofit for buildings in countries with hot-humid climates and aims to identify the optimal strategies for energy retrofitting buildings in hot-humid climates using an optimisation method. The results of this study will significantly impact stakeholders’ decision-making processes, enabling them to identify the most advantageous objectives and energy efficiency measures for retrofitting buildings.
