g-Function Interface

[j-c-cook]

A g-function interface struct is going to be necessary for EnergyPlus to interact with this library.

• borefield : struct
  • A borefield object needs constructed that provides easy interface to custom, L, U, Open and rectangular fields
  • Handles uniform height (in meters) H, uniform burial depth (in meters) D, uniform borehole radius (in meters) r_b
• time : vector
  • There are different geometric time routines available. EnergyPlus could call the same routine based on an input duration (in months) and optional number of time steps nt
• alpha : float, optional
  • The ground thermal diffusivity (m2/s)

The determination of the number of segments nSegments will be handled by the adaptive discretization scheme. If desired, the ability to turn off adaptive discretization and use a custom number of segments could be made possible.
