Utilising Latest Developments in Chiller Technology Delivers Energy Savings and Ongoing Cost Reductions for Fiserv

Fiserv, Inc. (NASDAQ: FISV) provides information management and electronic commerce services such as transaction processing, electronic billing and payments, and business process outsourcing for banks, lenders, credit unions, insurance forms, merchants, government agencies, and leasing companies.

Fiserv operates in two primary business segments - financial institution services and payments and industry products — primarily in the US market with overseas representation in 20 additional countries around the world. 

In the UK, Fiserv occupies a modern office building located in Stockley Park, Uxbridge, which provides almost 38,000 square feet (3,530m2) of floor space. This building was built in 1986 and Fiserv has been based there since 2001.

The comfort cooling in the UK headquarters is provided by air handling units and fan coils, with the chilled water supply coming from a single packaged air-cooled chiller located at roof level. Due to ongoing issues with its existing chiller, Fiserv decided to invest in a replacement chiller, and following a process of competitive tender Johnson Controls were selected to provide a turnkey solution.
