Background

Hanwha has been operating the solar solution business since 2010 and has occupied the No.1 market share in the United States, UK, Germany, Japan, and South Korea. Nevertheless, because the solar solution business is B2B, the Hanwha brand is not well-known to the public as a solar solution provider. Since 2011, Hanwha has created a total of seven forests by only using solar energy in China, South Korea etc. However, campaign awareness remained low and there was also a lack of understanding of the difference between Hanwha's ultimate eco-friendly forestation way and the others’. Even in the COVID19 pandemic situation, to make more people aware solar solution business part of Hanwha and make them experience how the solar solution provides public benefit especially in terms of environment and sustainability, we decided to apply the concept of gamification to this campaign and created the world’s first sunlight-controlled mobile game.

Due to COVID-19, as most tree-planting campaigns initiated by NGOs and environmental organizations got canceled, Hanwha’s tree-planting campaign was not an exception as well. However, instead of canceling the campaign, we decided to execute a non-contact campaign. Hanwha's Forest has a distinctive characteristic that it does not emit carbon while growing young trees because Hanwha uses electricity created from only solar energy, unlike others who use electricity from fossil fuels. To convey this important characteristic effectively and allow people to engage in tree planting while practicing social distancing, we decided to implement the whole process of forestation in reality to the mobile device and release the campaign digitally. We developed a mobile game app: ‘Solar Forest’. This digital tree-planting game utilizes a light sensor to grow virtual trees with natural light shined on the device and allow fully grown trees to be donated to the real forest.

1)Prototyping: With the concept of ‘growing seedlings with sunlight’, we quickly started prototyping. Since the factor of sunlight was the most important thing, we first checked if the sunlight can be checked with smartphones and how accurately it can be calculated. 2)Game Planning & UI/UX Design: We built the game frameworks that "Flower Pot" stage of growing trees using sunlight, decorating "Personal Garden" with the grown trees, and donating "Personal Garden" to "Collective Forest". 3)Graphic Design: Several design concepts were tested to convey a familiar tone and mood for all age users. By testing different shaders and universal render pipelines, we got the overall design concept. Then, we started to design the element characters, plants, gardens and vertical forest. 4)Development & Test : continuous development processes and tests were conducted to improve game ability, game balance, and UI/UX. 6)Launch: Officially launched on World Environment Day(June 5th) 2020
