In a bid to combat climate change, commercial buildings must prioritize energy efficiency. EnerKey, a Finnish company, uses data analytics to help clients optimize their energy use in their properties. By connecting utility data with weather and geospatial information, EnerKey enables clients to make informed decisions about energy consumption. The company has over 80 integrations with IoT sensors and stores large volumes of time series data using InfluxDB, a platform that can handle automation and provide support for various use cases. With the help of InfluxDB, EnerKey's clients have achieved significant energy savings, including Kesko, which is already saving 5 million Euros per year and aims to save at least 7.5% more energy by 2025.
