Dew Point Analysis
We model critical façade assemblies to affirm the condensation resistance using the theory of water vapor migration. This data is combined with the system criteria for air infiltration to pin point potential breach areas and supplements the design and/or installation methods. We work with the MEP consultants to develop strategies to maintain internal air flow to further mitigate condensation under peak conditions.
Glazing Thermal Performance
With glass typically comprising a minimum of 40% of the façade, it is critical to select glass that will provide optimum thermal performance balanced with aesthetics and costs. Utilizing advance software, we analyze glass coatings, spacers and make ups to determine the highest and best glass solution. We further evaluate the comfort level at the vision glass line to determine temperature variables with natural ventilation and the mechanical systems melded with the glass performance.
System Thermal Performance
As modern facade becomes more articulated in plan and surface plane, thermal performance has become more of a challenge. We evaluate strategies for the specific climate including thermal improvement, thermal isolation and thermal reflectance for the entire façade of the building. The strategies are modeled to illustrate the vulnerable areas, these specific areas receive special attention during design engineering, production and installation.
Thermal Stress Analysis
Often one of the major causes of façade failures we look at is the thermal stress imposed on the façade elements. Self-shading of glazed surfaces, freeze-thaw exposure of natural materials such as stone, metal fatigue at high and low temperature ranges. Each component is considered in the thermal stress analytical process.
