Contribution of green technologies on infrastructure performance in Rwanda, a case of green buildings constructed in the green Gicumbi project

In Rwanda, integrating green technologies in building projects presents an opportunity to enhance infrastructure performance while minimizing environmental impact. However, the extent to which these technologies contribute to the overall effectiveness of these infrastructures remains underexplored, especially in rural contexts like the Gicumbi District. Therefore, this study aimed to assess the contribution of green technologies used in green building projects to infrastructure performance. To achieve this objective, the study used a descriptive research design and a census sampling technique to select the entire population of 107 people, including the residents and beneficiaries of the green buildings project. Primary data were collected through a combination of questionnaires, interviews, and direct observations, while secondary data were gathered through documentary analysis and published research studies. The findings revealed that all green technologies such as resources-efficient design, low-emission materials, and waste management have a significant positive influence on the performance of the Green Buildings project in the Gicumbi district where a increase of one unit in resources-efficient design, low-emission materials, and waste management would lead to increase of 0.152, 0.14, and 0.178 in performance of Green Buildings. The study concluded that the change of 65% in the performance of Green Buildings is due to green technologies in terms of resource-efficient design, low-emission materials, and waste management at a 95% confidence interval.
