Eat Local. Live Green.
The G-Roofs project was inspired by the emerging green roof systems across the world. For the purpose of better fostering the communication process between the rooftop service provider and anyone who want to get involved with the green roof activities, G-Roofs, an interactive mobile platform, is developed. This mobile application helps people reach out to green roofs and interact with the roof farmers, while at the same time learning more about organic foods and their benefits.

The story starts from the Green Roof system, a concept that has been bringing up more and more frequently worldwide, as part of a growing effort to meet the challenges that we face, including climate change, denser cities and the need for healthier neighborhoods. As one of the leading cities, since 2010, Copenhagen has become the first Scandanavian city to adopt a policy that requires green roofs for all new constructions with roof slopes less than 30 degrees.
Vegetated roofs, or green roofs, may provide various benefits for buildings and their surroundings. They can absorb 50 to 80% of annual rainfall in a sustainable way, by reusing the water to plant cultivation. While supporting biodiversity in the city, green roofs can also help reduce urban temperatures and mitigate the Heat Island Effect.
Currently, green roof projects have already been applied to many different settings in Copenhagen such as residential area, commercial uses, and public buildings through the forms of roof farm, rooftop eatery, and rooftop garden.
For each solution, a storyboard capturing a clip of user journey was created, hoping to dig more into the essence of each solution.
Paper prototypes were created for initial concept exploration. Additionally, several peer testing sessions were conducted in groups of three. My role was the "wizard" (acted as the mobile device) and the facilitator. The other two participants acted as the user and the observer. After quickly describing the project and few sample tasks, the user was asked to play with the system.
Major pain points that arose from the testing sessions are:
Accordingly, some adjustments were made with respect to the key user feedback along with three design iterations. Explore the final clickable prototype through:
Throughout the design process that involves a lot of testings, iterations and refinements, certain issues and limitations should be noticed. First of all, it was not until the final digital prototyping phase did I realize that with the current design, users would be limited to browse products in a single roof farm. There is no place for them to see and search products from all farms. This could be problematic for users who are not familiar with any of the roof farms or don’t have preferences in the beginning, but just want to find particular produces. This seems relatively easy to implement in the GUI design level, but could bring up a lot of issues, such as “who will be responsible of handling orders involving multiple farms” and “how could the application support collaboration between roof farms”.
Thinking ahead, although the current problem initially started from a green roof project in the city of Copenhagen, the topic of green roof has been discussed all over the world. European countries have long put this issue of fighting against global warming on top of their agenda. Many cities in the United States have also started different green roof projects in places such as Chicago. With the development of current mobile-based online platform, cities and green roof advocators could have a easier time creating public awareness on the environmental issue. Moreover, from the perspective of city residents and organic market customers, they could benefit from using the application by adopting healthier eating habits and lifestyle. For either creating a better living spaces or transitioning to a healthier and more sustainable lifestyle, the application could be helpful and impactful.
