IKEA, Centennial, CO

Status: Under construction

Brief description:

Taking a holistic approach to the building with the owner, architectural and engineering teams, Geo-Xergy was able to reduce the size of the ground heat exchanger significantly for the 415,000 square foot IKEA Store being built in Centennial, CO. Some of the changes implemented include high-efficiency lighting, white roof, heat recovery ventilation and CO2 sensors for the ventilation air.

Ice storage tanks were integrated into the mechanical system design to reduce equipment requirements and peak electrical loads.  Heat dissipation / snow melt in the loading dock areas was integrated into the system to eliminate the need for a cooling tower for the system.

Innovations:

• Geothermal heating and cooling with vertical ground heat exchanger under the building
• Controlled ventilation system
• Ice storage tanks
• Heat dissipation / snow melt.

Status: Under construction

Brief description:

Working closely with the architectural team, contractor and mechanical system designer, Geo-Xergy was able to reduce the size and cost of the ground heat exchanger by recovering energy from the display case refrigeration system.

Thermally enhanced grout was specified for the vertical boreholes to reduce the number of boreholes required, and reduce the number of boreholes required from thirty to 24.

Innovations:

• Geothermal heating and cooling with vertical ground heat exchanger
• Controlled ventilation system
• Heat recovery from display case refrigeration
