This study reviewed selected specific windows and reviewed the window performance certification criteria including KS F 2278 and KS L 9107 and analyzed the change in performance based on the change of area. This study also compared the heating and cooling loads of an apartment house applied with window performance reviewed in consideration of insulation and SHGC performance and actual size based on KS F 2278. The analyzed window was a double window composed of aluminum and PVC and the building was the apartment house model of 141 m². The analysis results were as follows. First, as the window glass’s thermal performance is superior to frame, the performance degraded in reduced area. In case of selected window, the 1 m X 1m window’s thermal performance and SHGC decreased by 35% and 37% respectively compared to 2 m X 2 m window. Secondly, in the comparison of performance for increasing area with 2 m X 2 m and 3 m X 3 m windows, the 3 m X 3 m window’s thermal performance and SHCG increased about 14%. Third, in the comparison of heating and cooling loads of the analyzed model considering the apartment house model applied with window performance derived from KS F 2278 and actual figures, the model’s total heating and cooling loads increased by 33% with cooling decreasing by 36% and heating increasing by 77%. Above analysis results show that evaluation of window performance based on criteria such as KS F 2278 and KS L 9107 may lead to distortion of performances different from actual products. Thus, it is necessary to suggest new evaluation criteria.

Window system is an essential component for lighting, ventilation and thermal environment in buildings. Moreover, as balcony extension in apartment houses become legalized, the performance requirements of window systems in balcony space are getting complicated. However, at this moment, five properties of the windows are used to represent the performance aspects of the system, including wind resistance, air tightness, water tightness, sound insulation, thermal resistance. And such single properties are not capable to express the performance of a space with the window systems in terms of performance concept. A performance analysis with wholistic approach is required to see the effect of the window system in built environment. Thus, performance-based approach should be established, which will be able to evaluate the goal/function and comfort of occupants/owners. As the first step to develop the performance indicator for the window systme for balcony space, this study conducts a survey to find the required performance aspects. A complete set of performance-based indicators will be developed with verification methods in the later stage of research.

Good Enough to Move? Window-Dressing Performance Impending Turnover in Inter-Organizational Mobility

Ahn He Soung,Ok Chi Ho 한국인사조직학회 2016 한국인사ㆍ조직학회 발표논문집 Vol.2016 No.1

This paper suggests that employees impending turnover may have incentives to window-dress their performance. Window-dressing of performance refers to the inflation of performance in more visible dimensions (i.e., high level of quantitative performance) and the deflation in other performance dimensions that reflect quality (i.e., low level of qualitative performance) by which actors aim to give a good appearance to potential destination firm. By doing so, employees manipulate performance signals for their self-interest to boost visibility in the labor market and garner more bargaining power throughout the turnover process. In this paper, we focus on the Korean security analysts market and empirically test our hypotheses with a sample on 496 inter-organizational moves made by 345 analysts during 2000 and 2013. We find evidence that analysts do in fact window-dress performance in times impending turnover, in the form of inflating forecast volume (quantitative performance) while deflating forecast accuracy (qualitative performance).

For energy saving in building, the manufacturer of architectural material has improvement the performance of window. But recently the designer and constructor prefer to wide part of window at building envelope because of fine view of building. The wide part of window at building envelope has raised to thermal performance for energy saving. So many researcher and productor enhanced window performance by various effort. For the control of solar heat gain, the smart skin was developed from smart glass like an electrochromic glass and suspended particle display. Also the performance of solar heat gain on transmitting envelope of building became important for energy analysis. The measuring equipment of that performance was proposed too. This method was regulated to Korea industrial standard. But the use of solar simulator has some problem that difference between solar simulator and natural sunlight. This mean is that the effect of natural sunlight through window or smart skin do not confirmed about an energy consumption in building. Therefore authors studied many research and previous study about the solar heat gain performance of smart skin and measured the solar heat gain performance of glass through using the measuring equipment of the solar heat gain performance by use sunlight. The authors of this study were development of measuring equipment of SHGC. By the operation pretest of measuring equipment, the application of the measuring method was confirmed. And the results of measuring about solar heat gain coefficients showed to requirement of improvement about equipment for smart skin.

윤종호(Yoon Jong-Ho),김효중(Kim Hyo-Jung),이철성(Lee Chul-Sung),심세라(Sim Se-Ra) 대한건축학회 2010 대한건축학회논문집 Vol.26 No.10

The concern of the world about Building Integrated Photovoltaic that can alternate with the exterior materials in the building is growing from day to day. There are many kinds of the solar photovoltaic which can apply to the building. Among them, a-si thin film solar cell is possible to alternate the window and to daylighting. So, if alternating the glass material that occupy the great part of building facade, growth possibility and the effect from BIPV will be maximized. Therefore, in this study, the database as to optical performance depending on the spectrum section that is the most base step was established for applying a-si BIPV window system in the building using thin film solar cell, And optical and thermal performance of a-si BIPV window system were evaluated by simulation. For conducting this, the optical properties of PV raw module and PV single module that are Tsol(0.086, 0.067 each) and Tvis(0.091, 0.082 each), SHGC(0.303, 0.295 each) were evaluated. And we analyzed thermal performance of a-si BIPV window system by the configuration of window components and we suggested the most suitable configuration methode of a-si BIPV window. Each of the U-factor of Double and Triple a-si BIPV window are 1.174W/㎡ㆍ℃, 0.863W/㎡ㆍ℃. As a result, optical properties of a-si BIPV window system has low transmittance comparing common window system but it can meet the illumination depending on the building use and reduce the glare effect that can occur when clear window system is used if a-si BIPV window system is applied on a large area in building facade.

Exploring the Black Box of Task-Technology Fit: The Case of the Korean Single Window System

Chang-Bong Kim,Don-Hyun Lee 한국무역학회 2014 Journal of Korea trade Vol.18 No.4

The global trade environment demands a safe and fast trade clearance system or the sake of trade facilitation and customer satisfaction. These circumstances are also important for the use of single window. I identified how to better use single window by analyzing the factors affecting its use. First, deducted factors affecting the utilization of single window external pressure(demands from trading partners), government support, CEO support, partnership, education and training, task fit and technology fit. As a second step, I analyzed their effects on the efficiency and effectiveness of single window utilization. This analysis was based on a survey of about 200 companies using single window, and the data was then analyzed with a structural equation model. This led to the formulation of the early model based on the Innovation Diffusion Theory, Technology-Task Fit, Task-Technology Fit and Technology Acceptance Model, and then to the Revised Models 1,2,3 and 4. I came to five important conclusions. First, task fit is enhanced when government support, CEO support and education and training on single window are enhanced. Second, as a result from Revised Model 1, task fit is significantly impacted when government support, CEO support, and education and training about single window are enhanced; the more task fit is strengthened, the more business efficiency is strengthened. Third, as a result from Revised Model 2, task fit is better when government support, CEO support, and education and training about single window are improved; the more task fit is strengthened, the more business effectiveness is improved. Fourth, as a result from Revised Model 3, task fit is more developed, when CEO support and education and training about single window are enhanced; the more task fit is developed, the more business efficiency is strengthened. Fifth, as a result from Revised Model 4, task fit is increased when CEO support and education and training about single window are strengthened; the more task fit is increased, the more business effectiveness is improved. I firmly believe that further research regarding the causal relationship between business task and technology fit and business performance should be conducted in order to enable Korean import and export companies to more effectively and efficiently utilize single window in the future.
