Structural passive cooling interventions such as cool roofs are used to reduce indoor ambient temperature. However, it is unknown how acceptable and desirable cool roof technology is in rural low-income settings in sub-Saharan Africa, where home occupants are exposed to rising indoor temperatures.
We engaged 48 participants in four focus group discussions to explore the factors influencing the acceptability of "cool roofs" in Nouna, Burkina Faso. We analysed the data using reflexive thematic analysis. We structured our findings using the acceptability framework developed by Sekhon, Cartwright and Francis (2017), which comprises seven components: affective attitude, burden, perceived effectiveness, ethicality, intervention coherence, opportunity costs, and self-efficacy.
Our participants described an environment of extreme heat and the need for adaptation strategies to reduce the temperature within their homes. The cool roofs would be deemed acceptable if they were affordable, effective in reducing heat, and aligned with values around self-efficacy, particularly in relation to local production and ownership.
Providing communities with technical information regarding how the cool roof functions and can be maintained may support uptake via acceptability. Desirability of the roof may be achieved via a combination of highlighting the indoor cooling of the roof as reported by users, sharing of results with the community so that they have an insight into the effects of the roof, and feedback regarding the products useability and durability.
诸如凉爽屋顶等结构性被动冷却干预措施被用于降低室内环境温度。然而，在撒哈拉以南非洲的农村低收入地区，室内温度不断上升，居民们暴露在这样的环境中，凉爽屋顶技术的可接受性和受欢迎程度尚不清楚。
我们组织了48名参与者进行了四次焦点小组讨论，以探讨影响布基纳法索努纳“凉爽屋顶”可接受性的因素。我们使用反思性主题分析对数据进行了分析。我们根据Sekhon、Cartwright和Francis（2017年）开发的可接受性框架来构建我们的研究结果，该框架包括七个组成部分：情感态度、负担、感知有效性、道德性、干预连贯性、机会成本和自我效能感。
我们的参与者描述了极端炎热的环境以及需要采取适应策略来降低家中温度。如果凉爽屋顶价格实惠、有效降低热量并且符合围绕自我效能感的价值观，特别是在本地生产和所有权方面，那么它们将被认为是可接受的。
向社区提供有关凉爽屋顶如何运作以及如何维护的技术信息，可能会通过可接受性来支持其采用。屋顶的受欢迎程度可以通过以下方式实现：强调用户报告的屋顶室内降温效果、与社区分享结果以便他们了解屋顶的效果，以及提供有关产品可用性和耐用性的反馈。
