Evaluation of Users' Satisfaction with Passive Design Strategies in Selected Large-Sized Churches within Lagos-Ogun Megacity, Nigeria

Increasing global temperatures from climate change lead to heightened dependence on artificial energy for indoor comfort, exacerbating global warming. Large-sized churches often rely on artificial systems, posing sustainability issues. Some churches, especially in the tropics, respond to this by adopting passive measures that meet user comfort expectations and align with environmental sustainability objectives. Acknowledging the significance of the user’s perspective in assessing the efficacy of passive design, this study endeavors to scrutinize user satisfaction with the utilization of passive design strategies in selected largesized churches situated within Lagos-Ogun megacity, Nigeria. Therefore, this study aims to evaluate user’s satisfaction with the use of passive design strategies in the selected large-sized churches in Lagos-Ogun megacity, Nigeria. The study utilized a combination of qualitative and quantitative methods. Qualitative data involved observations using a guide at four selected churches, analyzed systematically. Quantitative data involved a total of 211 participants responding to a structured questionnaire from the selected churches, and Statistical Product and Service Solutions (SPSS), version 27 software was used for data processing, analyzing the users' satisfaction levels with each of the selected churches. The outcomes were presented descriptively, employing text, tables, and plates for clarity. The study found that respondents rated passive design techniques in churches as fairly adequate for user satisfaction, yet artificial means were also used for comfort. It recommends that large churches integrate both passive and active design strategies from the initial stages to not only satisfy congregants but also contribute to broader environmental sustainability goals.
