This project was implemented in a municipal collective center in Guayaquil, providing assistance to migrant and local populations in need of accommodation. The solution involved infrastructure upgrades integrating low-environmental-impact construction techniques. These cooling systems are based on the principles of passive architecture and low energy-consumption technologies to mitigate heat stress by reducing ambient temperatures within the building. To further enhance climate resilience and minimize energy consumption, photovoltaic systems were installed, alongside the installation of vertical gardens on the external walls and the use of native bamboo on external walls and windows to mitigate solar radiation and regulate interior temperatures.

The project specifically targets hazards associated with the coastal location, including heatwaves and heavy rainfall events during the rainy season. To address these challenges, rainwater harvesting systems were integrated into the shelter’s design. These systems not only contribute to water conservation efforts but also serve to mitigate risks of localized flooding, particularly in the exterior areas surrounding the collective shelter

What specific aspects of your design address climate challenges?
Heatwaves:
o Wind Extractors and Eco Coolers: These systems help reduce high temperatures inside the building.
o Green Walls: Vegetation on walls reduces solar radiation exposure on the building’s exterior.
Flooding:
o Rainfall Harvesting Systems: These systems mitigate the risk of localized flooding outside the main building.

How do these features work?
Heatwaves:
o Wind Extractors and Mechanical Fans: Powered by solar panels, these fans push hot air upwards into wind extractors, maintaining a cooler indoor temperature and enhancing comfort for occupants.
Flooding:
o Rainfall Harvesting System: Installed outside the shelter, this system includes a 500-liter tank and a sediment filter, which supplies water to the main cistern for tap water inside the building.

What strategies does your solution use to mitigate climate risks?
• Reduction of Solar Radiation: Utilizing green facades to lower heat absorption.
• Low Impact Construction Techniques: Implementing methods that minimize environmental impact.
• Rainfall Harvesting: Collecting and reusing rainwater to reduce flooding and water consumption.

How effective are they?
Reduction of Temperature:
o Temperature Difference: Post-intervention, the temperature difference between the exterior and interior improved by 2.80°C, from an initial 3.40°C to 6.20°C. Additionally, indoor humidity decreased by an average of 6.37%, making spaces feel cooler and more comfortable without the need for air conditioning.
• Reduction of Electricity Consumption: Achieved a reduction of 31.40 kWh per person.
• Reduction of Water Consumption: Achieved a reduction of 2.51 cubic meters per person.
