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.
