This study examined the applicable capacity of the photovoltaic system of two blocks of the apartment complex for each ZEB certification grade through a solar simulation program. District heating is applied to the two blocks of the apartment, and the Ⓐ block is higher-rise than the Ⓑ block. Accordingly, since the Ⓐ block has a relatively long district heating pipe length and pumping power, the primary energy requirement was calculated to be higher. As a result of calculating the PV applicable area of the roof and the facade using the solar simulation program, the roof was found to be in the range of 54 to 73% depending on the building arrangement, and it was analyzed that the average of 65% was applicable. The facade was found to be available as much as 15% of the total facade area in the southeast and 20% in the southwest. As a result of applying the PV system according to the ZEB certification grade, it was analyzed that up to Grade4 can be achieved only by the rooftop area, and it was found that the facade area from Grade3 should be available. As the maximum achievable level, Ⓐ block was analyzed as ZEB Grade3 and Ⓑ block as Grade2.
