Founded in 1833, Sparkasse Jena-Saale-Holzland is one of the largest savings banks in Thuringia. 150,000 customers value the savings bank, with its approximately 500 employees, as a local financial partner. As a public-law institution, the savings bank is committed to the common good and economic development in the region. The savings bank therefore commissioned Dr. Wolfgang Junge from ERA Group to review and optimise the cleaning costs for its more than 40 branches. At the start of the project, cleaning costs amounted to around £250,000 per year.
