Simulation Study of Building Envelope Performance Using Microclimatic Meteorological Data
نویسندگان
چکیده
To accurately calculate heat, air and moisture (HAM) transfer in building envelopes, appropriate boundary conditions need to be specified. A previous study by Salonvaara and Karagiozis showed that calculations of moisture content in brick cladding could differ up to thirty times in magnitude when using different weather data sources. This study aims to investigate the effect of using urban (downtown) and suburban (Pearson Airport) weather data on HAM and wind driven rain (WDR) simulation. It was found that the temperature and humidity are very similar and WDR experienced differences between the two datasets. By utilizing WUFI for simulation of fifteen years of data, it was discovered that some WDR events peak at different times, however, the moisture can dry out in a reasonably short period of time. Also there are minimal differences in heat transfer between the two sets of data. Further, more detailed studies should be carried out with high resolution data to confirm such findings.

Thermal building simulation currently uses Typical Meteorological Year (TMY) data to guide the design decision-making process or for compliance with energy standards. TMY data usually excludes extremes and in many cases are gathered from microclimatic contexts that are not sufficiently representative of the project sites (e.g., airports), adding uncertainty in the analyses. To enable a quantifi...
