The concern over efficient use of energy in buildings has raised a debate from various parts of the world. The justification for this debate emanates from the understanding that continued utilization of non-renewable sources of energy presents a challenge towards sustainable development. In developing countries where urban growth is largely unguided, the capacity of urban authorities to guide orderly spatial development is limited and the challenge towards realization of energy efficient city forms is imminently becoming more apparent. This apathy has resulted into city spatial patterns that do not guarantee effective and efficient energy utilization. The paper attempts to analyze the impact of the urban form, the in-door spatial adaptability on building energy consumption patterns. This study was conducted in one of the rapidly transforming commercial districts of Dar es Salaam, namely Kariakoo. The methods used for data collection included; literature review, field observations and measurements, analysis of plans, maps and interviews with space users and officials. Measurements of climatic elements of temperature and humidity were also conducted. Results indicate the rapid physical transformation of Kariakoo from single storey to multi-storey buildings has culminated into increased energy utilization. However, these transformations have been taking place with little regard to recommended plot coverage and floor area ratios. This has resulted into uncomfortable indoor living conditions and excessive utilization of energy. Adapting to these challenges, most households were putting on electricity light during day time, fans and use of air conditioning units. It has been recommended that building energy consumption patterns can be moderated with appropriate urban, architectural and electrical design within the context of a strong and efficient legal framework. The enforcement of the legal framework can be done by coordinating efforts from various stakeholders from rel
