Outside surface resistance: proposed new value for building design.

Type of article: Article

Summary

Findings of outdoor full-scale experimental studies show that the experimentally measured values for the convection coefficient are significantly higher than the values assumed in current design guidance. An expression derived from four full-scale investigations is presented. A modified design value for the external surface resistance is proposed for the condition of "normal" exposure to replace the current value of 0.06. As a result, it is recommended that the corresponding U-value for single glazing be raised to 6.3 watts/m2.K from its currently accepted value of 5.6.
