Dakotah! Ice Center Green Features

• Eight skylights coupled with daylight harvesting sensors reduce energy consumption by providing natural daylight to the arena.
• Overhead lights are equipped with three levels of switching:  ‘low’ for cleaning, ‘medium’ for practice, and ‘high’ for game time. 
• Sixteen solar panels in two banks of eight each sit atop the roof to heat water for use in the ice resurfacing equipment.
• A heat exchanger takes waste heat from the ice compressor system and redirects it to heat the concrete bleachers.
• Arena seating made from recycled materials.
• Amenities include two mezzanine levels, an elevator, seven locker rooms, a new concession area, conference rooms, and a concourse viewing and seating area.
• Low flow and efficient faucets, showers, and toilets conserve water.

• By using these pavers, the SMSC saved 7,000 tires and 210,000 plastic containers from entering landfills.
• VAST Permeable Composite Pavers reduce water runoff into storm drains and decrease pollutants by infiltrating rainwater on the building site.
• With an independently tested infiltration rate of more than 400 inches per hour when installed with an open-graded base, VAST Permeable Composite Pavers decrease the rate and volume of rain runoff from parking lots, driveways, sidewalks and patios.

Green Roof

• 32,648 square feet
• Treats storm water
• Improves energy efficiency
• Reduces total storm water runoff from the building and erosion
• Improves water quality
• Has an extended roof life because it is protected from ultraviolet radiation.
• A typical roof will last about 20 years; the green roof is designed to last 40 years.
• Simplifies temperature management inside the facility, because the insulating roof minimizes temperature swings inside the building. This reduces energy use.

  

Green Roof Soil

• There are six inches of special light-weight green roof soil on the Dakotah! Ice Center roof for a total of 750 cubic yards (or 62 dump truck loads) of soil.
• A revolutionary new green roof soil called “CoPu®” was installed on the Dakotah! Ice Arena roof.
• CoPu is a pumice-based green roof soil that has the highest water retention capability and plant growth characteristics available. It is comprised of pumice, ground coconut husks, and pine bark.
• Pumice is a volcanic rock with millions of tiny pores that retain water and allow air flow that promote plant growth.
• The pumice used in CoPu comes from the Glass Mountain pumice deposit in northern California.
• A special soil amendment called, “mycorrhizae,” was used on the Dakotah! Ice Arena green roof. Mycorrhizae are specialized fungi that help green roof plants get established and greatly extend the surface area of the roots, providing resistance against stress.
• The thirty-foot diameter SMSC crest was donated and installed by Aloha Landscaping, Inc. and designed by Derek Young. The granite edging used to outline the crest was salvaged during excavation of the oldest bridge in Minneapolis.

  

Green Roof Sub-Surface Drip Irrigation

• Over 16,000 feet of drip irrigation tubing is installed on the green roof.
• Sub-surface drip irrigation system has 8,110 emitters that release 4,818 gallons of water per hour.
• Sub-surface drip irrigation creates a wetted area 45% larger than surface drip irrigation systems.

  

Green Roof Research

• A study on research plots of about 750 square feet looks at water coming and water going out from the green roof, thus measuring how much the plants are using.
• A comparison study of utility expenses for the existing ice arena and the new one looking at a return on investment. The green roof is thought to reduce energy costs though definitive data is still being collected. The SMSC research team hopes to produce quantitative figures to prove this theory.
• A viewing platform and stone path through the green roof makes it easier for tour groups to access the green roof.
