Abstract
The problem of energy saving is relevant nowadays. Great attention is especially paid to improving the energy efficiency of different building envelopes, since the heat consumption is a significant part of total costs for utility needs.
Purpose: The aim of the paper is to study the state of the building envelopes nearby the outer corner.
Research findings: Methods of reduction of the negative impact of the thermal bypass nearby the corner manifest themselves in condensation, mold, and subsequently lead to the envelope destruction. The use of insulated bevel edge leads to better results than that without insulation. But the minimum dew point temperature remains at corners and does not exceed 13.5 °C. Only in this case, the minimum dew point temperature moves to bevel edges.
Value: The thermal bypass (outer corner) effect on the temperature field of its inner surface is studied. Three wall thicknesses are investigated: 510, 640, and 770 mm. It is shown that in all cases the corner temperature decreases below the dew point temperature.
