Indoor Environmental Quality (IEQ) in Nigerian Tertiary Institutions: The Effect on Performance of Building Technology Lecturers

Purpose: This study aimed to examine the Effect of Indoor Environmental Quality (IEQ) on the Performance of Building Technology Lecturers in Nigerian tertiary institutions. Methodology: Three research questions guided the study in which survey research design was used. The entire population of the study was 216, comprising 84 building technology lecturers and 132 higher technical officers from six tertiary institutions in Nigeria. A 38-item questionnaire was used for data collection. The instrument was validated by three experts. Cronbach’s Alpha reliability method was used to determine the internal consistency of the instrument at a coefficient of 0.89. A total of 216 copies of the questionnaire were administered and 210 copies were retrieved, representing a 92% return rate. The data collected was analyzed using mean, standard deviation and t-test. Results: The study found out that there exist 5 items on how the indoor air quality (IAQ) affect building technology lecturers’ performance in Nigerian tertiary institutions, 5 items on how thermal comfort affect building technology lecturers’ performance in Nigerian tertiary institutions, 7 items on how building acoustics affect building technology lecturers’ performance in Nigerian tertiary institutions and 6 items on how ergonomics affects building technology lecturers’ performance in Nigerian tertiary institutions. The study also found 6 items on challenges of installing Indoor Environmental Quality (IEQ), facilities and 10 items on the ways of providing and improving Indoor Environmental Quality (IEQ), in Nigerian tertiary institutions. Practical Implications: Lecturers’ role on monitoring and maintenance of IEQ in offices could be enhanced through appointment of Desk officer in each faculty of the tertiary institutions. The Desk officer will liaise between the lecturers and maintenance unit of the institutions on IEQ issues. Originality/Value: The study concluded that improved indoor environmental quality has a tremendous impact on lecturer’s performance, comfort, workspace utilization and overall productivity.

Descriptive Survey

This study investigated the areas of cooperative learning approaches for sprouting employability in polytechnic building technology students’ in Nigeria for the expertise of practice upon graduating from school using descriptive survey research design. Two research questions and four null hypotheses guided the study. The population for the study consisted of 99 building technology lecturers that offer building technology programmes in Federal, State and Private Polytechnics in South-East and South-South Nigeria. Since the population was not too large, there was no sampling. The instrument used for data collection was a 36-item questionnaire derived from the literature reviewed. Five experts validated the instrument. Cronbach alpha reliability method was used to determine the reliability of the instrument and a reliability coefficient of 0.87 was obtained. The research questions were answered using Mean statistic, while the null hypotheses were tested using Analysis of Variance (ANOVA) and z-test at .05 level of significance. The findings revealed among others that lecturers utilize all the aspects of cooperative learning approaches; and that all the employability skills required by building technology students/graduates can be developed using cooperative learning approaches. Based on the findings of this study, it was recommended among others that assessment of building technology students should be all-encompassing to include the development and mastery of employability skills for functionality in the ever dynamic and global workplace.

Purpose: The study identified the rationale for material selection in landscaping for checking intrusion in public and private primary schools in Nsukka urban, Enugu state, Nigeria. Methodology/Approach/Design: A descriptive survey research design was adopted for the study. Three research questions guided the study. The population for the study was 102 respondents comprising 82 public/private school teachers and 20 builders. Due to the manageable size of the population, there was no sampling as the entire population was used for the study. The instrument used for data collection was a 25-item questionnaire derived from literature reviewed. The instrument was validated by three experts from the Faculty of Vocational and Technical Education, University of Nigeria, Nsukka. Cronbach’s Alpha was used to determine the reliability of the instrument and a reliability coefficient of .85 was obtained. The data collected for this study was analyzed using mean and t-test. Results: The findings revealed some rationale for material selection in landscaping for checking intrusion in public and private primary schools which includes; the durability, maintenance, aesthetic and cost of each landscaping material; the initial and ongoing costs, the availability of the material to be used and the life cycle assessment considerations such as material performance, and impact on the environment and the ability to reuse the material. Practical Implications: The results of the study might be of interest to school principals and builders. The study reflects the common perceptions about landscaping to prevent intrusion into schools, and hence of practical implications to concerned education authorities in Nsukka urban, Nigeria. Originality/Value: The study identified the effects of poor landscaping in public and private primary schools which include; exposure of schools to risk of attacks, theft and exposure of schools to ecological problems such as flooding, erosions, deep gullies and a degrading environment.

Study Questionnaire

This study identified capacity building needs of farmers in rearing and marketing of duck in Benue State, for sustainable food security. The study was carried out in Benue state. Three research questions and three hypotheses guided the study. Questionnaire survey research design was used for the study. A population of 96 respondents was studied. A 36-item structuredDuck Rearing Capacity Building Needs Questionnaire (DRCBNQ) was used for data collection. The instrument was validated by three experts. Cronbach Alpha reliability method was used to determine the internal consistency of the instrument and a coefficient of 0.81 was obtained. 96 copies of the questionnaire were administered but only 95 were retrieved and data collected were analyzed using mean Improvement Need-Performance Index (INPI). It was found out that poultry farmers needed capacity building in all the 9 items on feeding of duck, needed capacity building in all the 11 items on management of duck and needed capacity building in all the 16 items on marketing of duck. It was therefore recommended that Agricultural extension agents should utilize the findings of this study on the capacity building needs of farmers to organize training and re-training programmes for improvement of capacity of poultry farmers in the entire production operations of duck. Farmers could be motivated to attend training and re-training programmes organized for their capacity building in duck production to be effective and efficient in duck production to meet the demand for duck in Benue State

Practical Implications

PurposeThis study examines occupants' satisfaction with the indoor environmental quality (IEQ) of a green-certified building [The Green Star South Africa (SA) Building] in Ghana.Design/methodology/approachViews of 300 respondents are solicited on 15 IEQ (obtained through a critical review of the literature and complemented with a pilot interview on the subject) parameters. Data obtained are analysed using both descriptive and inferential statistics.FindingsFindings suggest that occupants are generally satisfied with five critical aspects of IEQ. The results also indicate that the occupants perceive five key IEQ parameters to have high levels of importance. Further inferential analysis of the parameters revealed that two core IEQs require the highest levels of improvement actions.Research limitations/implicationsThe study was conducted in Ghana and analysed occupants' perceptions of working within one green-certified building. Again, the collection of the occupants' responses was not linked with the direct measurement of physical characteristics of the IEQ parameters of the building. Hence, the findings cannot be generalised.Practical implicationsPractically, the study contributes to providing all stakeholders involved in the Green Star SA Ghana certification system with the relevant feedback for their decision-making on current and future projects to be certified under this certification system.Originality/valueThis study provides valuable information on the performance of IEQ parameters of the building and points out potential IEQ areas that need improvement efforts, especially concerning current and future facilities certified under this certification system.
