Old Smartphones Transform Building Systems: Energy Efficiency

Automated building systems offer a great potential for reducing the energy consumption of properties. Studies on such systems show that optimized solutions can reduce the energy requirements of buildings by around 30 percent on average. In order to avoid the necessity to produce new and emission-heavy computer chips, Empa researcher Hanmin Cai is currently investigating the extent to which damaged smartphones that are no longer used could perform these control and maintenance tasks.

Automated building systems can reduce energy consumption by around 30 percent on average. Empa researcher Hanmin Cai is investigating the possibility of using damaged smartphones for control and maintenance tasks in these systems.

Digitalization is becoming more prominent in various aspects of life, including the building stock, which accounts for 40 percent of Switzerland's energy consumption. Self-learning algorithms are being developed to optimize building operation based on structure and usage.

Startup viboo's smart control system can achieve 30 percent energy savings through automated heating and cooling. However, these systems require computing power and communication channels.

Cai is exploring the use of old smartphones for building systems to avoid the production of new emission-heavy chips. Initial tests with old smartphones show promising results in regulating room temperature and managing electrical battery charging within a simulated power grid.

The project is still in early stages and requires further analysis on standardization, security, longevity, and life cycle emissions. Cai's research may lead to significant reductions in emissions compared to using newly manufactured control units..
