Integrating Green Architecture Principles in the Design of Office Building towards Improved Energy Consumption in Abuja, Nigeria

Abstract

The growing concerns over the adverse effects of buildings on the environment and the need to achieve users’ thermal, visual, acoustic, spatial, and indoor environmental air quality comfort have given rise to the demand for energy-efficient buildings. This study aims to integrate green architecture principles into the design of an office building in Abuja, Nigeria, with the goal of improving artificial energy consumption for optimal building performance. The research instrument that was employed for data collection was the survey questionnaire administered to professionals in the built industry and occupants of office buildings. Four hundred and sixty five (465) questionnaires were administered to the study population, and three hundred fifty (350) questionnaires (75%) retrieved. The analysis of the data was carried out using descriptive analysis, percentage, and mean item score. The findings revealed that respondents agreed that the energy use and activities in office buildings in Abuja led to an increase in the amount spent on fuel (MIS = 4.32). The findings further revealed that the respondents agreed that green architecture policies should be enforced in Nigeria (MIS = 4.40). The findings revealed that the office environment in relation to the following: natural lighting and natural ventilation (MIS = 3.44 and 3.31) are good. The study concluded that integrating green architecture principles is necessary for improving energy consumption in the design of office buildings. It was recommended that designers should ensure the implementation of proper design and orientation, leveraging climatic conditions and the use of more efficient equipment, which helps reduce energy consumption, consequently leading to a reduction in energy bills, improved indoor air quality, and lower carbon emissions.
