In this study, we analyze the performance characteristics of BIPV (Building Integrated Photovoltaic) system of Climate Change Research Building of National Environment Research Institution which was designed with the aim of zero carbon building. This building totaling 2449 m(2) is consist of five laboratories, PR (Performance Ratio) department, conference room and others, and the area of conditioned space is 1668 m(2). In addition, the remaining residual load was predicted to 99,200 kWh when load reducing system was applied such as insulation, exterior shading device and lighting control. BIPV system, which is consist of three modules; G to G (Glass to Glass), G to T (Glass to Tedlar/Crystal) and Amorphous, has 116.2 kWp of total capacity, and is applied to wall, window, atrium and pagora on roof. After the completion of building, the total amount of energy consumption and the gross generation of BIPV system were 104602.4 kWh and 105266.6 kWh through a year from April 2011 to March 2012, respectively. It was evaluated to achieve zero carbon building because the energy surplus was 664.2 kWh. (C) 2013 The Authors. Published by Elsevier Ltd. All rights reserved.
