Benchmarking Case Study: 600 Tower

600 Washington Avenue, St. Louis, MO 63101

600 Tower Benchmarking Case Study

The 25×20 Voluntary Energy Benchmarking Campaign challenges buildings in the St. Louis Region to benchmark their energy use. Energy benchmarking is the key to unlocking potential energy and cost savings. Since the campaign was launched, businesses, local governments, houses of worship, schools, and institutions have pledged to benchmark their energy use!

25×20 participants include 600 Washington, now featured in a benchmarking case study. This 25-story office building, formerly known as One City Center, is a 375,000 square foot office building with a variety of tenants, including several large legal and accounting firms. Originally built in 1985, the tower overlooks the former St. Louis Centre mall which has since been transformed into a 750 space parking garage in 2010.

DTZ, which recently merged with Cushman-Wakefield, manages the building to keep its approximately 600 occupants comfortable. They initially completed the 25 x 20 Benchmarking Challenge as a means by which to track energy consumption over time. Additionally, ongoing comparison data sets are used to identify anomalies in energy and water usage. It has also been used as a marketing tool to attract potential tenants.

The building achieved a high enough score that will allow them to apply for an Energy STAR rating in approximately 18 months. They have completed lighting retrofits in a number of common areas, as well as a portion of tenant spaces, and have encouraged tenants to implement computer power management programs and turn off non-controlled lighting. They have additional lighting and HVAC retrofits planned for the future, along with an upgrade to their building management system.
