Ventilation, once a given, has become a luxury.
Traditionally, ventilation efficiency in Nigerian homes was primarily accomplished through louvered windows in traditional buildings from the 80s, 90s, and early 2000s, which provided over 98% ventilation. These designs enhanced airflow and temperature regulation, especially when window sizes and types were thoughtfully incorporated into the building specifications. Residential structures were built with the comfort and satisfaction of inhabitants as a key focus.

Now, let’s look at the reality of today’s world. The shift from traditional to modern residential architecture in Nigeria has significantly affected how well homes are ventilated, leading to a greater reliance on artificial methods for controlling airflow. The term cross-ventilation has become virtually obsolete; achieving natural ventilation has become a premium commodity. Design priorities have shifted entirely from occupant comfort to visual aesthetics and profit-making.
I can tell with certainty that every residential building being built has windows that are smaller than the previous one. It looks like there is an award for the person who constructs the house with the tiniest windows these days. Given the present heat wave pandemic and the lack of trees in some areas of the nation, it makes sense that they would be taken into account while constructing residential buildings for the tenants. Because consistent electricity is still unattainable in our nation, residents shouldn’t have to endure thermal discomfort as a result of inadequate or nonexistent ventilation.
It’s difficult to ignore the irony that, while building larger, more costly homes, we breathe worse inside them. There is no additional cost to a building budget for a standard-sized window, but its absence costs people money, comfort, and health in the form of electricity bills, generator fuel, and restless nights. Natural ventilation is a design principle that all architects, developers, and regulators should strive to preserve; it is not a thing of the past. Our homes will continue to appear spectacular from the outside while silently failing the people who live in them if we continue to treat occupant comfort as an afterthought or a luxury.
