Saints Business Center
Project Type: Sustainable Multi-Tenant Office Warehouse and Brownfield Cleanup
Client: St. Paul Port Authority and United Properties (Developer)
Winner of the 2017 Sustainable Saint Paul Award for Green Building Design in New Construction, the Saints Business Center is the first speculative multi-tenant office warehouse project in the nation to receive LEED CS–Silver pre-certification. A 190,000 SF precast concrete panel office warehouse building and site improvements on an existing urban site were designed.
The existing Saint’s stadium buildings and site structures were demolished and removed. Concrete, bituminous, and brick were recycled on site, with contaminated soil and non-recyclable debris disposed of off-site. A Subsurface Vapor Extraction System and sub-slab depressurization system was installed, included equipment to actively remove vapor.
The brownfield site remediation plan included removing soils in contaminated hot-spot areas and disposing these soils at a state-regulated off-site facility. The storm water treatment system eliminated runoff from the site for the 100 year, 24-hour storm event by infiltrating all the runoff and recharging the aquifer.
Storm water control systems included SAFL Baffles, pervious pavement, and an underground tire shred infiltration basin and connection to municipal storm water systems utilizing tire shreds.
A 40 KwH photovoltaic system will produce enough energy to power the building exterior/parking lot lighting. Energy efficiency strategies will result in an 18% reduction in energy use. Water efficiency strategies will result in an 40% reduction in potable water use.
