ASSESMENT OF THE ADOPTION OF GREEN BUILDING TECHNOLOGY TECHNIQUES ON WORKERS' PERFORMANCE IN PUBLIC OFFICE

Abstract

Green Buildings (GB) can improve occupant satisfaction, productivity and overall wellbeing (Quandung et. al.; 2020). Poor adoption of GBT has led to poor indoor air quality in building in Nigeria, resulting in negative impacts on occupants' health and productivity (Oyedepo, 2017). The Nigeria Government has made efforts to promote the adoption of Green Building Technology (GBT) for sustainable development by establishing Nigerian Green Building Council (NGBC). In this light, this paper seek to assess effect of the adoption of green building technology on workers' performance in public office buildings in Abrija, Nigeria by adopting the quantitative research approach. Data were collected with the use of structured questionnaires which were administered to 105 purposively sampled respondents who are both construction and non-construction professional public servants. Analysis of data was undertaken with the use of descriptive (Mean Item Score, MIS) and inferential (Spearman Rank correlation analysis) statistical techniques. Findings from the study revealed that the techniques involved in the adoption of GBT for public office buildings most adopted are "Daylighting" (MIS = 4.18) and "Direct solar gain" (MIS = 4.04). The most significant perceived effects of adoption of GBT on performance of workers in public office buildings are "GBT results in a high-quality" (MIS = 4.03) and "GBs help to reduce the demand for new power plants" (MIS = 3.91). There exists a strong, positive and significant relationship between the adoption of Indoor Air Quality/Lighting and workers' satisfaction in public office buildings in Abuja (r = 0.474/0.420; p = 0.000). The study concludes that the impact of GBT on workers' performance in public office buildings in Abuja is significant and can enhance healthier working environment and maximum output for office workers. It was therefore recommended that construction firms to collaborate with other stakeholders to set up mechanism for enhancing the adoption of GBT for public office buildings in Abuja.
