Architect Julio A. Romero recommends external awnings to cut indoor heat

Architect Julio A. Romero explains that blocking sunlight before it reaches a home is far more effective at keeping night‑time temperatures low than using interior curtains. He says, "Para no tener calor por la noche es más efectivo desplegar los toldos que cerrar una cortina," noting that awnings shade windows and portions of the façade, reducing thermal inertia and allowing small airflow currents that help dissipate heat.

He adds that proper ventilation should be done during the coolest parts of the day – at dawn or dusk – and that keeping interior doors open improves air circulation. Ceiling fans are recommended over regular fans, and placing ice in front of a fan can further lower perceived temperature. Romero warns that using heat‑producing appliances such as irons, vacuum cleaners, or hair dryers during peak heat adds to indoor warmth, and he advises limiting heavy winter décor, dark curtains, and thick carpets. Light‑coloured exteriors, indoor plants, and, where humidity permits, light misting can also contribute to a cooler home environment.
