The Hot, Hot, Hot Days of Summer

(A nod to Arrow’s classic calypso)

The scorching sun of our Caribbean summers feels more intense than ever—and the data confirms it. In the year, Jamaica ranked highest in the world for climate-driven heat anomalies, with high temperatures made four times more likely due to climate change (Jamaica Gleaner). Forecasts from the Caribbean Climate Outlook Forum (CariCOF) highlight a “persistent unusual warmth” and recurring heatwaves across the region during the peak season (Jamaica Observer).

Understanding this reality, architects in the tropics, especially in the Caribbean must step up by designing buildings that aren’t just beautiful—but cooler, more comfortable, and climate-conscious.

Here's a Few Ways We Mitigate Heat in Our Designs:

Strategy	Description
1. Minimize paved surfaces	Reduces urban heat buildup and controls stormwater runoff.
2. Reflective & insulated roofs	Reflect up to 80% of solar radiation and lower surface temperature by 11–60%, cutting cooling energy demand by up to ~20% (ScienceDirect, FSEC®).
3. Cross ventilation	Strategic openings can improve natural airflow, creating a constant cooling breeze and reduce indoor temperatures without air conditioning - lowering indoor temperatures by up to 5°C (greenbuildingadvisor.com).
4. Low-E / reflective-glass windows	Cuts solar heat gain by up to 50%, improving comfort and energy efficiency (IEN Consultants).
5. Indigenous, drought-resistant vegetation	Tall shade trees soften heat and elevate cooling naturally.

By integrating these strategies, we achieve cooler interiors, lower energy bills, and lessen environmental impact—helping homes thrive even under our relentless sun.
