The main objective of the Nigerian building sector working on achieving energy efficiency is to decrease energy demand of buildings and thereby reduce the negative implications of urban development and poor energy infrastructure on people's wellbeing. One of the key strategies being adopted for substantial reduction of energy demand in the Building Energy Efficiency Guide for Nigeria is the bioclimatic architectural design approach. Hence, intelligent design of buildings, especially the building envelope, can considerably improve energy efficiency and help to realize heating and cooling targets. The aim of this paper is to promote and encourage sustainable building development in Nigeria by developing a systematic and context-based framework for the design of energy efficient residential buildings. This study adopted a mixed method approach of interviews with 12 architects and 22 householders. Moreover, measurements and observational surveys of 22 existing buildings that fit into three distinct building typologies were conducted. Three existing buildings were investigated using a building simulation approach to compare their performances, especially in terms of thermal comfort. The data collected was analysed using content analysis, descriptive statistics analysis, and simulations. The interviews with architects and householders showed enormous potential to reduce residential buildings’ energy demand. To achieve this, the interviewees emphasized the need for strong collaboration between all stakeholders in the building sector. Measurements, observational surveys, and case studies of existing buildings confirmed that thermal discomfort in residential buildings and challenges with building design, have a significant effect on the building occupants’ wellbeing. The research developed a framework for the design of energy-efficient residential building, which is expected to enhance sustainability, particularly in the building sector. The framework was produced based on the findings from the research data and the review of relevant literature. It involves an integrated process focused on bridging the gap between building stakeholders |
