Strong Winds

Highly insulated envelope or external insulation systems are being applied in recent energy saving buildings to reduce the heat loss through envelope. Internal insulation systems are applied to most apartments in Korea because they are inexpensive and convenient to construct. However, the internal insulation systems have poor performance due to the heat bridges through structures such as slabs. The external insulation systems have better thermal performance because the heat bridges through the structure are rarely formed. But it has problems regarding the external insulator separation due to strong winds, spread of fire due to insulator combustion in case of fire, formation of heat bridges through the connectors between structure and external insulation. To supplement the weaknesses of the internal and the external insulation systems, a sandwich insulation system has been suggested. In this study, the thermal performance of sandwich insulation system for apartment buildings was evaluated according to two type of the form-tie material.

The Heat Transfer Coefficient

The thermal performance of a new regenerated glass pumice board as external wall thermal insulation material was analyzed in this paper. Considering the roles of solar radiation and air convection, and selecting Wuhan city as an example of the hot summer and cold winter zones, the temperature field distributions of the external building walls in different orientations in summer and winter seasons were numerically simulated by using the finite element software ANSYS. The thermal performance of regenerated glass pumice exterior wall external insulation system including the heat transfer coefficient and the temperature distribution was evaluated. The simulation results demonstrate the good thermal insulation performance of the regenerated glass pumice as a new kind of external wall materials, and the feasibility of the application of this environmentally friendly material to the wall insulation system in energy conservation building is also promoted.
