Impact of Green Building Technology on Goal Attainment and Efficiency in Construction Industries in North West Nigeria

Abstract

The study was carried out to determine the impact of green building technology on goal attainment and efficiency in the construction industries in North West Nigeria. Three research questions answer The study, while three null hypotheses formulated were testes at 0.05 level of significance. The study adopted descriptive survey design and was carried out in North -West Nigeria. The population for the study were 50, Comprised of 28contractors and 22 engineers. There was no sampling because of manageable size of the population. A 50-item questionnaire was used for data collection. The instrument was validated by three experts Lecturers from department of Industrial Technical Education, University of Nigeria Nsukka, while 0.81 was obtained as reliability coefficient value using Cronbach alpha reliability method. Fifty copies of the questionnaire were administered on the respondent by the researcher and three research assistants. Out of the 50 copies of the questionnaire administered, 48 copies were retrieved indicating 94% rate of return. The data collected were analyzed using mean to answer the three research questions while analysis of variance was employ to test the hypotheses at 0.05 level of significant. The findings on hypotheses revealed that there was no significant difference between the mean responses of the respondents on the goal attainment and efficiency in construction industries for using green building technology. Based on the findings, the study recommended that construction industries in north-west should adopt and utilized green building technology in their construction projects.
