IBM’s contributions towards achieving the United Nations Sustainable Development Goals.
"At PhotonStar Technology Ltd., Watson IoT data is combined with the local weather forecast, allowing operators to anticipate weather conditions and adjust building temperature, lighting, heating, and cooling parameters to eliminate wasted energy. The solution can save up to 50 percent of heating costs by triggering proactive decisions based on live weather conditions. For example, building managers can remotely turn on building heating systems when cold weather is moving in. The solution also enables automatic window shade lowering or raising in response to changes in sunlight and temperature."
