Chapter One — 1.1 Background to the Study

Over the past decade, the relationship between passive cooling design techniques and thermal comfort has become a subject of considerable debate among scholars and industry practitioners alike, particularly within the context of Nigeria and Selected ECOWAS Member States where operating conditions differ markedly from more developed markets.

Nigeria and Selected ECOWAS Member States presents a useful setting for examining this relationship precisely because the conditions there — structural, regulatory, and behavioural — differ from those typically assumed in the broader literature, most of which draws on evidence from more developed economies.

1.2 Statement of the Problem

While passive cooling design techniques is widely discussed in policy and industry circles, empirical evidence on its actual effect on thermal comfort within Nigeria and Selected ECOWAS Member States remains sparse and, in places, contradictory. This lack of localized, rigorous evidence makes it difficult for decision-makers to know with confidence whether current approaches to passive cooling design techniques are helping or hindering thermal comfort — a gap this study sets out to close.

1.3 Objectives of the Study

1. To examine the effect of Passive Cooling Design Techniques on thermal comfort in Nigeria and Selected ECOWAS Member States.
2. To assess the extent to which passive cooling design techniques influences thermal comfort within the study area.
3. To identify the challenges associated with passive cooling design techniques in relation to thermal comfort.
4. To recommend strategies for optimizing passive cooling design techniques in order to improve thermal comfort.

1.4 Research Questions

1. What is the effect of passive cooling design techniques on thermal comfort in Nigeria and Selected ECOWAS Member States?
2. To what extent does passive cooling design techniques influence thermal comfort within the study area?
3. What challenges are associated with passive cooling design techniques in relation to thermal comfort?
4. What strategies can be adopted to optimize passive cooling design techniques in order to improve thermal comfort?

1.5 Significance of the Study

Beyond its academic contribution to the field of architecture, this study has practical value for management teams within Nigeria and Selected ECOWAS Member States seeking to understand how passive cooling design techniques translates into measurable outcomes around thermal comfort. It is equally useful to students and future researchers looking for a localized empirical reference on this relationship.

1.6 Scope of the Study

In terms of scope, this study confines itself to Nigeria and Selected ECOWAS Member States, focusing specifically on how passive cooling design techniques relates to thermal comfort within that setting. Findings are interpreted within these boundaries rather than as universal claims applicable to every organization or market.
