Assessment of Climatic Design Strategies for Enhancing Indoor Air Quality in a Proposed Heritage Center in Badagry, Lagos State

This study investigates the application of climatic design strategies to enhance indoor air quality (IAQ) in a proposed heritage center in Badagry, Lagos State. Recognizing the health and conservation challenges posed by high humidity and inadequate ventilation in tropical heritage buildings, the research evaluates passive architectural techniques suitable for the region. The study is guided by three core objectives: examining Badagry’s climatic conditions and their influence on IAQ; assessing building forms and orientation strategies that support natural ventilation and daylighting; and exploring sustainable materials and construction methods that align with both environmental and cultural preservation goals.
Using a quantitative research design rooted in positivist philosophy, data were collected through structured questionnaires distributed to 303 respondents, including architects, curators, cultural heritage professionals, and visitors. Statistical analysis using SPSS revealed strong stakeholder agreement on the role of orientation, cross-ventilation, large windows, and traditional forms in improving IAQ. Findings also highlighted widespread support for sustainable materials and adaptive construction methods that honor heritage conservation while enhancing thermal comfort.
The study underscores the importance of climate-responsive design in heritage architecture, advocating for passive cooling techniques, local low-emission materials, and green buffers. It concludes with strategic recommendations to integrate environmental performance with cultural sustainability, promoting healthier indoor environments and resilient heritage spaces.
