It sounds like an NRC grant to me.<br><br>

This is also called a Subterranean Heating and Cooling System (SHCS). It
seems difficult to model. Not only would you need to accurately model the
solar and envelope loads through the greenhouse, but you would need
accurate modeling of the stratification of air temperatures, heat and
moisture transfer from the underground piping to the soil, from the soil
back to the air, and ideally from the soil to the plants as well.<br>

<b>Subject:</b> [Bldg-sim] Greenhouse "Climate Battery"<br>
<br>
<br>
Anyone have experience modeling a greenhouse "climate
battery"?<br>
<br>
Did you use IES, DB/E+ or none of the above?<br>
<br>
More information about the strategy --<br>
Hot air from the top half of the greenhouse volume is stored in a below
grade heat sink using large ducts which extract air using a fan. (image
below)<br>
