Abstract : The increase in greenhouse gas emissions in the atmosphere is a threat to biodiversity. This challenge is being solved by introducing green building practices such as making use of natural lighting, use of solar heating systems, using materials like bamboo which are long-lasting and renewable which aid in reducing energy, water, natural resource consumption and improving waste management in buildings which human beings spend most of their time. Although past research has established a correlation between the level of stakeholder awareness and the rate of uptake of green building technologies, this postulate had not been tested in Nairobi City County. Thus, this study focused on adoption of green building practices in Langata, Nairobi County, Kenya. The study adopted a survey research design; utilizing both quantitative and qualitative methods of data collection including semi-structured questionnaires, inspection checklist and interview schedules.The variables assessed were; the level of green building awareness of construction practitioners, regulatory measures of green building practices and the environmental sustainability indicators ofgreen building technology. The sample size comprised of 100 samples from a total population of 13,126 comprised of construction players including quantity surveyors, construction practitioners and project managers and residential buildings built between 2010 and 2020, two floors and above were the focus of the study. The collected data was analyzed using Microsoft Excel version 13 and SPSS version 25. To test hypotheses, regression analysis was performed. The level of awareness as variables had R-Square of .106, F- calculated of 10.357 and p≤.002; The Regulatory measures had R-Square of .172, F- calculated of 15.644 and p≤.003 and environmental sustainability had R- Square of .241, F- calculated of 13.742 and p≤.002 on adoption of green building technology in Langata Nairobi County, Kenya. The findings indicated that data was significant and alternative hypotheses were acceptable to be statistically significant. The findings depicted that majority of construction workers were not aware of green building, Kenya Green Building Society and neither were they trained on green building. Regulatory measures were implemented at a moderate extent but green building policies had not been incorporated in the current construction guidelines. The study also showed that green building practices such as waste management, energyand water efficiency are being observed well. The conclusion is that most respondents do not clearly understand green building technology, implementation of the already set green building policies is still a challenge and there is a great change in people’s attitude towards building sustainably. It is recommended that more awareness and training should be done, regulations established and enforced and government should provide incentives to encourage green building technologies. The findings of the study provide additional literature on the subject matter for further research. It also helps policy makers in formulating policies which may enhance the uptakeof green building technology in the study area.
