To evaluate the energy efficiency of the building envelopes with ventilated cavity, the reduction on cooling load and heating load were analyzed with ESP-r simulation program which is possible to interpret the energy consumption on various types of building envelopes. For the economic assessment of the ventilated cavity in the internal part of the office building envelope, the column & spandrel type was compared with the conventional curtain wall. The result of the computer simulation shows that 11.2~13.7% of the cooling & heating energy can be reduced in building envelope with ventilated cavity.
