Abstract:
Knowledge of the expected long-term performance of building envelopes subjected to the simultaneous heat and moisture transport is critical during the design stage. In-creased incidents of rapid deterioration of high-rise building envelopes have further extended this concern to the rehabili-tation of such structures. For durable and energy-efficient constructions, the knowledge of how the structurelconstruc-tion behaves when subjected to a persistently harsh environ-ment is needed Recently this behavior has been simulated by sophisticated computer models that incorporate the trans-port physics of heat and moisture in porous construction ma-terials.

This paper investigates the influence of the variability of measured moisture transport properties on the overall hygrothermal performance of a high-rise construction wall. The analysis was carried out using a state-of-the-art hygro-thermal model The LATENITE model is a two-dimensional heat and moisture transport program tailored specificallyfor building envelope investigations. For the present simula-tions, the model was adaptedfor one-dimensional conditions and hourly simulations were predictedfor a one-year perfor-mance of a high-rise wall section. Three types of facade cladding were used: two with red brick (one with an ex-tremely high water vapor permeance, one with normal per-meance) and one with a sandlime stone facade. Several cases for the wall systems were tested to determine the rela-tive influence of moisture transport properties of the wall on the predicted results.
