Two very different seasons
In much of Nigeria the year is split between a rainy season, with heavy storms and humid heat, and a dry season, with harmattan dust and dry air. Many buildings are designed for one and suffer in the other.
For the rainy season
- Keep water out. Roof overhangs, good gutters and raised floors protect walls and foundations.
- Let air move. Cross ventilation reduces the damp, sticky feeling and helps prevent mould.
- Drain well. Slope the compound away from the building and keep drains clear.
For the dry season and harmattan
- Control dust. Windows and doors that close properly help, and so do planted screens around the compound.
- Shade the sun. The sun can be harsh between harmattan spells, so keep roof and west-facing walls protected.
- Watch the cool nights. Nights can feel cooler, so rooms with adjustable vents and shutters stay comfortable.
Features that work all year
- Light-coloured roof with ventilated space under it
- Adjustable openings, such as louvres and windows that open fully and close tightly
- Trees and planting on the sunny sides
- Floors and walls that dry out quickly after rain
