Thermal Transmittance

The assembly U-values and effective R-values for the panel—key thermal performance indicators of our high performance wall systems—are listed below at various scenarios for the assemblies shown in the figure below.

Condensation Risk

The condensation risk was evaluated for Vancouver, BC, Toronto, ON, and Edmonton, AB based on the 2.5% January Design Temperature from NECB 2017. Table 3.1 illustrates the indoor air dewpoint temperature for a range of indoor relative humidity.

Dew Point Temperatures at Various Interior Relative Humidity

*Condensation risk results are presented assuming an interior relative humidity of 50%

Based on these conditions, the following condensation risk indices were found:

1. Critical Locations and Surface Temperatures: The coldest surface temperatures were found at various locations within the assembly that could be exposed to interior air. Three locations were identified for the evaluated assemblies and are shown in below in the diagram.

2. Maximum Allowable Interior Humidity: Based on this temperature and the interior air temperature, the maximum allowable interior relative humidity (RH) before condensation could occur was determined for the critical surfaces*. The maximum allowable interior RH is the highest level of interior humidity that can be present in the space before it raises the interior dew-point temperature above the critical surface temperature and condensation can form. This can provide further estimation of condensation risk if there could be some variability of the interior humidity conditions. These insights have informed design strategies in UnitiWall’s real projects, where climate control and envelope performance are mission-critical.

*The risk of condensation occurs when surface temperatures drop below the interior dew point, which is dependent on the temperatures and relative humidity of the interior air.

Critical locations and sample temperature plots are shown in the figure below. The table below provides the surface temperatures at the three critical locations for the panel.

*Temperatures less than the interior dew point temperatures indicates a risk of condensation for that room type. Numbers in red are at risk of condensation. **These results are for a single panel assembly and do not account for panel joints and other interface details which could increase condensation risk.

Critical locations and temperature plots below the dew point temperature are shown in the next figure. The table below provides the maximum interior RH for panel.
