[BLDG-SIM] underground thermal energy storage for snow melt system

[Jeff Haberl]

The Oklahoma and Texas Dept of Trans have developed similar systems for deicing overpasses using heat pumps and/or glycol in a solar system. Energy is stored in the embankment.

Subject: [BLDG-SIM] underground thermal energy storage for snow melt system

I came across a very interesting research paper titled "PROSPECTS OF 
SNOW MELTING SYSTEMS (SMS) USING
UNDERGROUND THERMAL ENERGY STORAGE (UTES) IN JAPAN" authored by Kinya 
Iwamoto, Shigeyuki Nagasaka, Yasuhiro Hamada,
Makoto Nakamura, Kiyoshi Ochifuji, and Katsunori Nagano of Hokkaido 
University in Sapporo, Japan. The system described uses underground bore 
holes, a circulation loop, and pavement as a solar collector to store 
summer heat underground for use in winter for snow melt. The only 
energy-using device is the circulation pump. I have been unsuccessful in 
contacting the authors since my email is regarded as spam by their 
webserver.

Does anyone know more about this system and/or its installation in North 
America? And there is probably a handful of you who have modeled it in 
TRNSYS or EnergyPlus, right?

Thanks,
Ellen
