The growing concern on the reduction of energy consumption in the residential sector of
national economies rests on some parameters and issues that deserve to be resolved.
Fundamental among these issues are the architectural concern, the appliances/services
efficiency issue; and most recently the human behavioural dimension. This study focuses on
the architectural issue with the objective of determining the level of energy efficiency
consideration in housing design practice by the housing stakeholders in Nigeria, with a notion
that arousing the professional cultures of the stakeholders, particularly architects and building
service engineers in the direction of efficiency can help improve energy efficiency design
practice. This is in recognition of the fact that more than one third of the world’s energy is
used in buildings; and a majority in houses and apartments (Wulfinghoff, 2003) [1].
Therefore, instituting energy efficiency design practice would lead to attainment of
significant reduction in household energy consumption. This study employs opinion survey
on the stakeholders (architects, building service engineers and builders) as a measure of their
perception and practice in our attempt to evolve energy efficiency housing design practice
guidelines. The result reveals an obvious gap in housing design practice and energy
efficiency consideration in Nigeria.
