The Caribbean Rule of Comfort

In hot-humid climates, your house stays comfortable when you do two things well:

1. Stop direct sun from hitting glass and walls (external shade)
2. Keep air moving through rooms (cross-ventilation)

Windows bring in light and breeze—but without shading they also bring heat. This strategy shows how to balance both, room by room.

The “3 Layers of Shade” System (Use Everywhere)

For each room, aim for at least two of these:

1. Roof overhangs / deep eaves (primary shade)
2. Verandah / gallery / covered terrace (best comfort buffer)
3. External devices (louvers, shutters, screens, fins, pergolas, vegetation)

1) Living Room / Family Room
