Ammon News - The Jordan Meteorological Department (JMD) said on Sunday that indoor spaces often remain cooler than outdoor areas due to various factors associated with building design and how these structures interact with their environment.
The JMD identified six key factors contributing to homes being cooler than the streets:
1. Retention of Cool Air:
Walls, windows, and doors help retain cool air indoors for extended periods, especially when limited ventilation prevents warm air from entering during the day.
2. Reduced Sunlight Exposure:
Interiors typically receive minimal direct sunlight, allowing them to lose heat more rapidly than outdoor areas exposed to constant sunlight.
3. Thermal Properties of Building Materials:
Materials like concrete in walls and ceilings absorb cool temperatures at night and gradually release them indoors, enhancing the cooling effect.
4. Variation in Air Movement:
Outdoor wind enhances the sensation of warmth from the sun during the day, whereas indoor air tends to be more stagnant, amplifying the perception of cold.
5. Absence of Natural Heat Sources:
Outdoors, the sun and ground absorb and radiate heat throughout the day, whereas homes lack such natural heating sources unless artificial heating systems are used.
6. Impact of Humidity:
Higher indoor humidity, especially in poorly ventilated spaces, intensifies the feeling of cold, while outdoor humidity is often lower due to better natural air circulation.
To solve this issue, the Jordan Meteorological Department recommended ensuring proper ventilation during the day to allow warm air and sunlight to enter, and using thick curtains at night to retain heat indoors.
