Gardening strategies for heatwaves and facade cooling

To combat rising heat and protect building exteriors, gardening techniques focus on both plant selection and proper installation. When using vegetation to cool facades with external thermal insulation (ITE), it is recommended to maintain a distance of at least 15 cm between the wall and the plants. Using independent supports like galvanized trellises or stainless steel cables allows for a ventilated air layer, which prevents moisture buildup and protects the facade's coating from damage.

For low-maintenance gardening during heatwaves and water restrictions, certain drought-resistant plant varieties are highly effective. Recommended species include Agapanthus, Dipladenia (Brazilian jasmine), Nerium oleander (oleander), Yucca, Sempervivum (houseleeks), and Agave. These plants are noted for their ability to thrive in full sun with minimal irrigation requirements.
