This study focuses on design tendencies in office buildings of public institutions after tightening up Korea's building energy performance criteria. Important office design criteria and recommendations pay attention to the issues such as building orientation, greening buildings, building form, space and envelop by intensifying building energy performance related laws, government guidelines and evaluation systems. The design tendencies explored in this research are as follows. Office buildings mainly face south and have various types of indoor and roof green spaces not for ecological reasons but for the rest. Building depth becomes thinner and atria are inserted into office buildings to improve daylighting and natural ventilation. Building cores are located on north or west and east sides acting as buffer spaces to reduce heat loss and to block solar radiation. Office building envelop design includes various creative ideas to control or utilize solar energy as like three dimensional or double structured skin and window size variation to cope with the intensity of solar radiation. Further, solar energy generation systems are integrated with building component such as roofs, sun screens and windows. This study demonstrates that government's reinforcement of the building energy performance criteria drives the change in design methods and approach.

The IB is normally defined in terms of BA, OA, security system, information processing and telecommunications services However, the buildings being already in existence are deficient in two areas. One of these areas is building envelope and plan. The other area is mechanical, electrical and structural systems which do not provide the environmental quality required by IB. Existing technology and design knowledge are available to address these deficiencies. Especially, the office buildings being already in existence must meet IB requirement in order to achieve desirable office environment. They are a building envelope, moisture control, properly-located windows, shafts for duct, telephone and electric closets and acoustical environments. In this paper, a new approach to construct the work scope of remodelling the office building being already existence is described by contrasting the building performance criteria of IB. It concludes by speculating on the consequences of extrapolating the results of study to remodelling the office building being already existence.

For a general office building having a center core, the distinction between the outer wall and the compartment should be clear, and it should be set at a stack effect pressure distribution acting on the respective compartment by a relative area ratio of the respective leak compartment. In the case of office buildings with an independent core for core there, some blocks of shares and exterior pressure distribution in buildings and office buildings typically have different characteristics. Therefore, if the stack effect reduction measures, designed on the basis of a general office building are applied to a stand-alone building, the core of the building should reflect the unique pressure distribution characteristics. This study, performed as part of the object corresponding to the flat plan of the building in the diversification trend, analyzed the stack effect that actually occurs in an office building having the properties intended for stand-core construction, and thus on the basis of and tested by the method of using a conventional stack effect reduction measures. Reviewed in the study, an independent cored office building that does not have the air flow path through the specific space with respect to the center core type office building has a feature, and the variation in characteristics of the pressure distribution inside the building according to this air flow path stack effect was reduced by a variety of measures that should be applied to determine the application.

This paper presents a case study to investigate the monthly calculation method of ISO 13790 applied for a office building. The energy performance analysis according to improvement of insulation and air permeability of windows in K office buildings is investigated by means of building energy efficiency rating tool ($ECO_2-OD$). The K building energy system is tested experimently by the measurement of PMV(predicted mean vote) for the control of indoor thermal environment and heat transmission coefficient of windows and interior walls respectively, before and after the example K office building is remodeled passively. Therefore, Internet based energy assessment program of energy efficiency rating of office building can be applied as a program for the annual energy requirement and for evaluation of energy savings from the experimental and simulation results.

This study is to analyze the building layout of traditional government office building in Chungchong province with Chungchong-do regional maps and Eupjis(邑誌) being compiled in the late Chosun dynasty. The building layout of government office in Chungchong-do is followed in the wake of the spatial structure, Sam-Jo(三朝, three reign) and Oejeon-Naejeon(外殿-內殿), of Chosun dynasty palace. The planning principle of Sam-Jo at government office, Dongheon(東軒) territory for rule administration corresponds to Chijo(治朝) with a local governor who is the ruler, as for the Naea(內衙) territory which a family of him and he lives in, it is corresponded to Yeonjo(燕朝), and in the job space of Ajeon(衙前), it is corresponded to Oejo(外朝). As for the application of the inside and outside principle of provincial government office, Dongheon is corresponded to Oejeon and Naea to Naejeon. A compositive and an approach axis of government office in Chungchong-do is correspond with Dongheon in the center, and these axes form an central axis and an entry space of government office included Oesammun(外三門) Naesammun(內三門) Dongheon or Naea. Because an essential performance of provincial government office is provincial administration, the layout configuration of government office is a function, which is an expression of an official institution.

The performance of the daylighting in buildings depends on building site and shape. As an energy saving design strategy, daylighting is a key issue in green building design. In this paper, the influence of the adjacent or obstructed building on daylighting performance of the office building in urban area was analyzed. A typical office building about 20 storeys with obstructed buildings has been modeled and simulated using Radiance. The parametric simulations have been performed to analyze the influence of the daylighting performance (illuminance, luminance) of the analyzed office. The results show that the possibility of the glare was decreased when the obstructed building is located in south, also the illuminance level was significantly decreased. When the obstructed building is located in north, the changes of the illuminance level and luminance possibility were somewhat small compared to the unobstructed condition. The daylighting performance of the analyzed building was most affected by the obstructed building in winter season.

The basic heat transfer process that occurs in a building can best be illustrated by an electrical circuit network. Present paper reports the dynamic simulation of annual energy consumption in an office building by the thermal resistance capacitance network method. Unsteady thermal behaviors and annual energy consumption in an office building were examined in detail by solving the simultaneous circuit equations of thermal network. The results are used to evaluate the accuracy of the modified BIN method for the energy consumption analysis of a large building. Present thermal resistance-capacitance method predicts annual energy consumption of an office building with the same accuracy as that of response factor method. However, the modified BIN method gives 15% lower annual heating load and 25% lower cooling load than those from the present method. Equipment annual energy consumptions for fan, boiler and chiller in the HVAC system are also calculated for various control systems as CAV, VAV, FCU+VAV and FCU+CAV. FCU+CAV system appears to consume minimum annual energy among them.

This study examines changes and features of provincial office buildings in Suwon and Chungju after relocation during Japanese occupation. Gyeonggi and Chungbuk provincial offices(Gwanchalbu) were relocated by Japan. Gyeonggi Provincial Office in Suwon used HwaseongHaenggung buildings and moved to Seoul in 1910. After relocation, most of HwaseongHaenggung buildings used for Suwon Governmental hospital(JaHye Uiwon). Suwongun Office, Suwon public elementary school, Japanese Military and Suwon Police station also used HwaseongHaenggung buildings with the Hospital. At first, Japan remodeled local government buildings for their use. Most of HwaseongHaenggung buildings had been destroyed to build new buildings since 1920s. Chungbuk Provincial office in Chungju used DongHeon building which is Chungju local government building and relocated to Cheongju in 1908. DongHeon building changed to Chungju county office after relocation. This building was renovated. Chungju county office moved to other site, this building was used for Chungju county conference room. During Japanese colonial period, Suwon local government buildings were destroyed and replaced with new Japanese style buildings. Chungju local government buildings were also renovated or destroyed.
