Jemne Office Building
Project Type: Sustainable Office Renovation
Client: District Energy of St. Paul and NorthMarq Real Estate Services
This energy efficient office renovation won the 2017 Sustainable Saint Paul Exceptional Environmental Steward Award. One of District Energy’s primary objectives in renovating the Jemne building was to utilize it to showcase new technologies, best practices, and state-of-the-art equipment in a way that enables the company to continue to educate its employees, clients, and partners. From the initial design kick-off meeting, District Energy was committed to doing as much to achieve energy efficiency in this building as they would ever ask of their best client.
To this end, District Energy elected to use the State of Minnesota’s Sustainable Building 2030 (SB 2030) program to set and meet an aggressive energy efficiency standard. The design process involved collaborating with a mechanical and electrical engineering firm for schematic design services and energy modeling – rather than the more typical design-build delivery model.
The design process included testing and balancing the existing system to identify areas for improvement, and engaged a commissioning agent to verify that the building was constructed and calibrated to meet the owner’s design intent.
This integrative process resulted in a building that showcases the following energy efficiency strategies:
- District heating and cooling;
- Variable speed drives;
- Recirculating hot water pump;
- New LED lighting with daylight or occupancy sensors as applicable;
- Historic light fixtures retrofit with LED;
- Upgraded building automation system;
- Replacement of piping insulation and mechanical equipment determined to be in poor condition.
