GISA Data Center

The GISA Data Center, located in Halle (Saale), Germany, is operated by GISA GmbH, an IT service provider established in 1993. A notable feature of this facility is its innovative approach to energy efficiency, where waste heat generated by the data center is reused to preheat the company's offices during colder months. This system utilizes the cooling water, returning at approximately 21°C, to heat incoming cooler outside air, significantly reducing the need for additional heating and leading to substantial energy savings, such as approximately 22,000kWh reduced in January 2025 alone.

The data center operates under high security standards, being BSI-certified according to ISO 27001, ISO 27017, and C5-testiert, ensuring a high level of data protection and security for its cloud services (IaaS, PaaS, SaaS). GISA offers a range of IT solutions including managed cloud services, infrastructure & outsourcing, and platform management, catering to various industries such as public sector, utilities, and higher education. While specific technical specifications of the data center itself are not publicly detailed, GISA emphasizes its commitment to efficient resource utilization and climate protection through such initiatives.
