Green facades for thermal control by Ronstan International

Green facades are increasing in popularity as we learn of their benefits in amenity and thermal control. But success is not as simple as selecting a plant and popping it in the ground or bed. Ultimately, a green façade will be judged long after its installation, so factors over and above the right support structure, careful analysis, and good site execution are required. For example, a well documented maintenance plan that is understood by both builder and building owner alike is critical.

Success essentially comes down to three key areas;

Climatic.
As simple as it may seem we need to understand the site. The availability of sunlight and the potential for overshadowing are both critical. Wind tunnels can develop in city streets. Reflective surfaces of many CBD environments can lift the average mean temperature of the green façade several degrees higher than a city average. Both challenge local species and careful site analysis is a must.

Species.
Understand the purpose of the façade. Is it for aesthetics, screening, or thermal control? Leaf density is a key variable, but leaf colour and scent often take precedence. How and when the plants grow, deciduous or evergreen, fruit or flowers, and known pests all seem fundamental considerations, but impact on performance and maintenance.

Façade Design.
With species selected, the façade must be designed around the plants. How much room the plant needs, its proximity to the wall (on or off the face), its growth patterns and future dead weight, leaf density and wind loads, all affect the support structure design.
