Analysis

The Mass Correction Analysis shows how a Thermomass “high mass” wall behaves in a given climate in comparison to a ?low mass? wall (such as stick?built or insulated metal panel) as a whole in terms of building performance. This analysis produces a steady-state (material) R-value and the (effective) R-value required of a low-mass wall to match a Thermomass wall in BTU consumption. In other words, it shows that high mass walls will always perform at a much higher R-value than just the purchased or “material” R-value.

The Isothermal analysis shows how thermal bridges affect a wall assembly’s R-value, by comparing a wall featuring Thermomass systems to a competing wall system, such as one built with metal ties and solid?through concrete sections or brick and block cavity wall. This analysis produces a calculated (steady-state) R-value and a corrected R-value for each panel, as well as the percentage of loss for the walls.

The Energy Savings Analysis shows the expected energy savings per year from a Thermomass wall when compared to competing wall system. R-values from a mass correction or isothermal analysis are used. Calculated over a period of one year, only energy consumption through the opaque portion the wall is considered with this analysis.

Based on the theory of water migration present in the ASHRAE Handbook of Fundamentals, Dewpoint Analysis analysis is used to illustrate and predict the water vapor migration and condensation potential for a given wall assembly.
