Recently, the energy efficiency of buildings has become a big issue and the need of thermal performance analysis on transparent building envelopes has been substantially increasing since the energy consumption caused by heat gain or heat loss through transparent building envelopes is significant. The Solar Heat Gain Coefficient(SHGC) is one of the most widely used indicators for thermal performance of transparent building envelopes. The SHGC can be assessed by two methods: The first method is a spectroscopic method which is normally used to evaluate the SHGC of glazing units. This method may be suitable for glazing-only units but it is not easy to track all the spectrums that are transmitted, reflected, or absorbed by the complex fenestrations which contain shading devices because their non-coplanar shapes and irregularities in surfaces produce angular scattering effects. For this reason, NFRC is assessing the SHGC for complex fenestrations with the second method, calorimetric method. In this paper, published standards and methods on assessment of the SHGC are investigated. In addition, the characteristics of an alternative that relieve the difficulties recognized on those standards and methods are provided.

The building energy consumption and heat loss/gain caused by building envelopes are closely related to each other. Accordingly, thermal performance for building envelope needs to be assessed in a precise and objective manner. As a quantitative indicator for thermal performance of transparent building envelopes, the Solar Heat Gain Coefficient (SHGC) or g-value is widely accepted. The SI-lGC is generally derived by spectrometric method and calorimetric method. From Ute authors' previous research. the latter was found to be more appropriate for assessing complex fenestrations. With this in mind, the authors had conducted a series of calorimetric experiment using Artificial Solar Laboratory installed in Korea Institute of Construction Technology. Then the SHGCs of tested fenestration cases were calculated with the results from measurement and simulation. In this paper, the outcomes of measurement and simulation are compared. Additionally, factors that may cause differences between measurement and simulation are discussed. Furthermore, the means to diminish the difference and processes to enhance the reliability of the results are suggested.

빌딩 시뮬레이션 소형 학습 도구 개발 : 모델링부터 제어까지
김덕우(Kim Deuk-Woo),서원준(Suh Won-Jun),정지태(Jung Jitae),윤성환(Yoon Sung-Hwan),박철수(Park Cheol-Soo) 한국건축친환경설비학회 2011 한국건축친환경설비학회 학술발표대회 논문집 Vol.2011 No.3
This paper describes the experiences and lessons obtained from one of the PBL (Problem-based Learning) projects, a simple test-bed for building simulation study from modeling to control. A problem about how to enhance the understanding of building simulation skills and expertise, and hands-on experience from modeling to advanced control by using a simple test-bed is raised by a group of four graduate students. The aim of the project is to reduce the gap between textbook knowledge and real application. As the course progresses (offered with a weekly three hour class), a simple prototype (rectangular EPS box) has been developed with a halogen lamp inside to emulate the convective/radiative heating system. The PBL case study consists of five steps: (1) mathematical modeling of the EPS box with lamps, (2) development of a state-space simulation model for the given EPS box in LabVIEW, (3) calibration of the simulation model if a significant gap between the simulation and measurement exists, (4) application of an advanced control to the box, (5) realization of web-based user control interface (either by a standard web browser or smart phone). In the paper, the aforementioned five steps are discussed with the lessons of modeling, simulation and control which are learned from this PBL case study.
