Through a Public/Private Partnership (P3), the University was able to replace their 110-year-old coal-fired steam plant with a new natural gas plant. The new facility was relocated from the heart of campus to a service zone creating new academic expansion space on the main campus quad. The new footprint is 12,000 square feet smaller and represents the quiet efficiency of a distribution system that will reduce the carbon dioxide emissions by 40,000 metric tons a year, additionally reducing landfill space from ash produced by the prior plant.
The UND Steam Plant Project Received the 2020 Sustainability Innovation Award from APPA, a professional association for facilities management professionals in education.
The following design strategies were utilized:
Economy
- New facility reduces the original footprint by 12,000 sf.
- Simplification of exterior and interior finish materials (exposed insulated precast walls, exposed structure, burnished block walls, and sealed concrete floors).
- Future flexibility is built-in for a sixth 60,000 BTU boiler.
Energy
- The reduction in Carbon Dioxide omissions is the equivalent of taking 8,600 cars off the road, and the carbon sequestration would equal about 74 square miles of
forest.
- The project included retrofitting existing buildings across campus to reduce energy use. This was done through upgrades on building automation, lighting,
equipment, and HVAC systems. This combined with the new natural gas-boiler plant will save over $1M per year.
Optimization of Building Envelope for Climate
- Tight envelope that consists of continuous insulated panels, and highly efficient translucent panels.
Passive Strategies
- Utilization of boilers provide a source of heat in the plant, further reducing the energy use.
- Strategic placement of translucent panel on 40’ tall south façade to allow natural light to flood the plant floor, reducing artificial lighting usage, and allowing natural
light into the control and breakroom areas.
