The list provided below is an
indication of research needed to continue to develop the energy efficiency and
durability of building foundation systems. These needs have emerged from
the research carried out to date.
Development of a Computational Fluid Dynamics Simulation Model of Coupled
Compressible and Incompressible Flow with Quantum Mechanical Phase Change
for Foundation Insulation Systems.
Currently available hygrothermal building simulation tools (such the IBP
WUFI program) have been shown to be ineffective in reproducing the
experimental results from basement walls obtained at the Foundation Test
Facility. This emerges essentially from an inability of these codes to
include hydrostatic and hydrodynamic pressure driven advective bulk water
flows under continuous, plug and free surface flow conditions. A
further issue is their inability to accurately model solid/liquid and
liquid/gas phase changes simultaneously as well as their limitations with
regard to accurately reproducing adsorption and absorption physics without
reliance on continuum approximations such as sorption isotherms. While
these effects can be modeled to a greater or lesser extent with some
"standard" Computational Fluid Dynamics simulations, such simulations are
not tractable for practical building foundation design computation purposes
that require extended real time transient simulation periods (17000 hours or
greater) and large domains (100,000 control volumes or greater) in the
presence of multiple information propagation velocities.
of the Foundation Design Handbook.
This handbook was developed by the Underground Space Center for the
Department of Energy in the the mid-1980's. The information contained
in that publication is now completely out-of-date and even obsolete in many
respects. A new revision of the Handbook is sorely needed particularly
with the trend to build ever tighter and more heavily insulated envelopes to
achieve net-Zero and gross-Zero energy conservation performance.
