    Tropical Building Sustainability and the Energy Regulations
    (Preprints, 2024-08-21) Babalola, Daniel Olatunde; Ugah, Uzodinma. K.; Ekeh, E. Y.
    Tropical regions face unique challenges in building sustainability due to high temperatures, humidity, and heavy rainfall. While building energy regulations are essential for promoting energy efficiency, their effectiveness in addressing tropical climate conditions needs to be studied more. This research aims to systematically investigate tropical building sustainability issues and evaluate the impacts of building energy regulations on these challenges. The study will identify gaps in current regulations by analyzing existing research and recommend strategies for developing more comprehensive frameworks that promote sustainable building practices in tropical regions. This research contributes to developing effective policies and strategies for achieving sustainable and energy-efficient built environments in tropical climates.

    Sustainable Tropical Architecture and Building Energy Regulations
    (Preprints, 2024) Ugah, U. K.; Babalola, Daniel Olatunde; Nduka-Kalu, C. I
    : Tropical regions face significant energy challenges due to climatic conditions. This study investigates the interplay between sustainable architecture and building energy regulations in mitigating these challenges. The study aims to assess the effectiveness of existing building energy regulations in promoting sustainable architecture in tropical climates and identify key architectural strategies and regulatory frameworks for optimizing energy efficiency in tropical buildings. A comparative analysis of building regulations and case studies of sustainable buildings in selected tropical regions is conducted. The findings reveal that current regulations often must be revised to address tropical climates' unique energy demands. Incorporating passive design principles, renewable energy systems, and material selection is crucial for energy efficiency. It is recommended that building energy regulations be strengthened to mandate sustainable design strategies and provide incentives to promote the adoption of energy-efficient technologies.

    Bioclimatic design strategies and energy efficiency in an orthopaedic hospital in Nigerian cities: A cross-sectional study
    (Journal of Infrastructure, Policy and Development, 2024) Ekhaese, Eghosa N.; Abudulsalam, Ibrahim; Mohammed, Praise Ojuoluwa; Akindoyin, Akindoyin
    2050 building stock might be buildings that already exist today. A large percentage of these buildings fail today’s energy performance standards. Highly inefficient buildings delay progress toward a zero-carbon-building goal (SDGs 7 and 13) and can lead to investments in renewable energy infrastructure. The study aims to investigate how bioclimatic design strategies enhance energy efficiency in selected orthopaedic hospitals in Nigeria. The study objective includes Identifying the bioclimatic design strategies that improve energy efficiency in orthopaedic hospitals, assessing the energy efficiency requirements in an orthopaedic hospital in Nigeria and analysing the effects of bioclimatic design strategies in enhancing energy efficiency in an orthopaedic hospital in Nigeria. The study engaged a mixed (qualitative and quantitative) research method. The investigators used case study research as a research design and a deductive approach as the research paradigm. The research employed a questionnaire survey for quantitative data while the in-depth Interview (IDI) guide and observation schedule for qualitative data. The findings present a relationship between bioclimatic design strategies and energy conservation practices in an orthopaedic hospital building. Therefore, implementing bioclimatic design strategies might enhance energy efficiency in hospital buildings. The result of the study revealed that bioclimatic hospital designs may cost the same amount to build but can save a great deal on energy costs. Despite the challenges, healthcare designers and owners are finding new ways to integrate bioclimatic design strategies into new healthcare construction to accelerate patient and planet healing.

    INVESTIGATION PASSIVE STRATEGIES FOR THE DESIGN OF ART GALLERY FOR THE CENTRE OF CONTEMPORARY ART, LAGOS, NIGERIA
    (Covenant University Ota, 2025-07) TAIWO, Mofijioluwa Osborne; Covenant University Dissertation
    The preservation of artifacts in galleries is a critical challenge in Lagos, Nigeria due to the region’s tropical climate, which poses risks such as high humidity, temperature fluctuations, and poor ventilation. This study investigates the adoption of passive design strategies and practices in artifact preservation across galleries in Lagos, Nigeria.In this study, a mixed-method approach was employed, combining qualitative and quantitative data through interviews and case studies, focusing on four Lagos museums. Purposive sampling method was used to select the four museums. The research examined architectural design elements, material choices, ventilation techniques, and spatial organization in relation to the types of artifacts housed. Findings reveal that different gallery areas require specific passive design strategies based on artifact sensitivity to environmental conditions. While porous materials like laterite and rammed earth aid in thermal and humidity control, shading devices, strategic ventilation, and adaptive spatial layouts further enhance preservation. However, challenges such as inconsistent adoption of passive techniques, inadequate policy frameworks, and maintenance issues were identified. The significance of this research lies in its contribution to sustainable museum and gallery design in Nigeria. By demonstrating the effectiveness of passive design in reducing energy costs, improving artifact longevity, and promoting eco-friendly architecture, the study provides valuable insights for architects, curators, and policymakers. It advocates for a context-driven approach that integrates traditional building techniques with modern sustainable innovations, ensuring the long-term preservation of Nigeria’s cultural heritage
