A transient model [1] that simultaneously considers both thermal and mois ture transient transfer and their interactions in multi-layer non-cavity wall con structions is utilized. Based on the mathematical formulations and the develop ments of the model, a computer simulation program has been developed in order to investigate the impact of the hygrothermal boundary conditions on wall mois ture behavior. By employing the model, both the moisture transport process and the material moisture content within the different layers of a wall system can be evaluated at all possible material moisture conditions. Evaluation of moisture accu mulation within a typical wall system showed that the impact of boundary condi tions is highly dependent on the thermal and moisture characteristics of the wall components. Indoor temperature has been found to have a relatively considerable influence on moisture accumulation in the insulation layer. The presence of solar radiation can lead to considerable reduction in moisture accumulation.","PeriodicalId":435154,"journal":{"name":"Journal of Thermal Envelope and Building Science","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123656756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These EIBS specimens were instrumented prior to back filling with soil, and their in situ thermal performance was monitored over two years. Soil temperatures and moisture content were monitored concurrently. Weather data were recorded on a daily basis. Through analysis of the measured surface temperature records, the presence of water was detected at the outer surface during various periods of heavy rain and major thaws throughout the two-year period. During these periods, the surface of the concrete showed no evidence of water penetration through the insulation layer over most of the height of the basement wall. Since the test setup involved different thermal insulating materials placed next to each other, the presence of lateral heat flow was inevitable. Both 2-D and 3-D models were used to quantify the lateral heat flow across the edges of different in sulating materials. The measured spatial and temporal temperature profiles were used as boundary conditions. The thermal performance of each insulation specimen was found to remain sta ble over the two-year period and was not significantly affected by episodes of wa ter movement at the exterior face of the specimens.

The relation between the design and climatic conditions acting on a building is not well established. Research should be undertaken to clarify the rela tionship between climate and the moisture performance of a given wall assembly, i.e., to enhance the predictability of moisture performance for different wall assemblies when constructed with some deficiencies and exposed to a given climate. To improve the correlation between climatic conditions and design practice, mois ture management of a building envelope must involve the flow-through principles. The flow-through approach is, however, much more difficult than the currently used approach with barriers. The flow-through approach requires performing computer calculations of moisture balance of all layers of the wall with regard to heat, air and moisture transport over an entire year. This is the critical element of the integrated moisture management strategy.
