Abstract

This research examines the development of tropical buildings that address the challenges of climate change and population growth by integrating accessibility for all and designing buildings that consume less energy. This research aims to assess the social and technical conflicts between accessibility and energy efficiency, and to develop an evaluation framework based on optimization algorithms that finds a balance between the two. Testing phase change materials (PCMs), energy modelling using Energy Plus, and critical policy analysis employing Critical Discourse Analysis (CDA) are all integral components of the mixed-methods approach. The primary result is that PCMs can help maintain more stable temperatures without requiring significant insulation; however, issues with regulations and design persist. Standard designs may exceed energy limits, but generally make it more challenging to achieve places. Research indicates that to create inclusive and sustainable tropical architecture, it is essential to establish integrated criteria and employ a transdisciplinary approach.

Abstract

The hospitality industry in tropical climates faces significant challenges in managing energy use while trying to make buildings that are environmentally friendly in areas with high temperatures, humidity, and changing weather.  Hotels in places like Southeast Asia, the Caribbean, and sub-Saharan Africa usually use a lot of energy each year. This is mainly because they need heating, cooling, and lighting, which raises costs and harms the environment.  As tourism increases and climate change becomes more of a problem, energy-efficient hotel designs and sustainability metrics have become more critical in international policy frameworks. This systematic literature review assesses the efficacy of hybrid simulation methodologies, combining various modeling tools to evaluate climatic impacts on enhancing energy efficiency and sustainability in tropical hotels, in contrast to conventional standalone simulations.  Using a strict PRISMA-guided method, searches of databases found 95 records, which led to one relevant observational modeling study of medium-category Mexican hotels.  This study showed a statistically significant drop in CO2 emissions and energy use per room-year, with older guests seeing the most benefits. The review shows that hybrid simulation has a lot of potential to improve hotel energy systems and make operations more sustainable, even though the sample size is small, the data is simulated, and there is no meta-analysis.  Practical implications encompass the endorsement of pilot implementations, personnel training, and collaborations to mitigate financial obstacles.  The review also points out significant research gaps, like a lack of long-term data and a lack of representation for tropical regions. This shows that more empirical research is needed. In general, using hybrid simulation methods could make hotels in tropical climates more energy-efficient and better able to handle environmental changes, which would help the hospitality industry become more sustainable.
