The objective of this study is to develop the blind control strategy and method which reduce negative effect of incoming daylight on visual comfort of occupants, minimize psychological anxieties caused by frequent motions of a blind, and maximize positive effect of incoming daylight and solar irradiation by opening/closing of a blind. As previous researches on blind controls have limited outdoor environmental conditions to those in specific regions, orientations and dates, these resulted in problems at various conditions for general-purpose application. Major problem is that the time interval and amount of blind movement do not meet the control objective at the end of control zone and discontinuous curve. To overcome these limitations revealed in the previous researches, following tasks were performed in this study. 1) To establish the control objective to accomplish the goal of this study. 2) To develop the control methods and algorithms which prevent glare on the work-plane at any time and which control the time interval and amount of blind movement to follow the control objective at various profile angle curves. 3) To validate the general-purpose applicability and performance of the developed control methods and algorithms by simulation and its data analysis at various conditions. It was found that the proposed methods and algorithms can prevent the direct glare on the work-plane at all the time and also increase the incoming daylight and solar irradiation.

The existing daylight analysis systems using computers are system independent, which means each system constructs own data for the daylight analysis in a separate way, and the data and information exchange between systems is not possible. If a single case of daylight analysis is compared, analyzed and evaluated in different systems, each system will repeat unnecessary process of producing, constructing and analyzing the same data. This causes a waste of resources and expenses in these works, and interferes with accurate, clear comparison and evaluation of the results owing to the possible errors and mistakes in the process of producing and constructing the data needed in each systems. Accordingly, this study aimed 1) to develop "Common Data Model & Analysis Module" for Daylight Analysis in order to share, exchange, analyze data between various systems that are operated independently, Also 2) aimed to consider the future extensibility of those applications on the web. And 3) aimed to propose this "Common Data Model & Analysis Module" as a prototype & protocol standard for daylight analysis system.

The objective of this study is to develop the blind control strategy and method which reduce negative effect of incoming daylight on visual comfort of occupants, minimize psychological anxieties caused by frequent motions of a blind, and maximize positive effect of incoming daylight by opening/closing of a blind. In previous researches on blind controls, major problem is that the time interval and amount of blind movement do not meet the control objective at the inflected zone of solar profile curve. To overcome these limitations revealed in the previous researches, following tasks were performed in this study. i )To establish the control objective to accomplish the goal of this study. ⅱ )To develop the control methods and algorithms which prevent glare on the work-plane at any time and which control the time interval and amount of blind movement to follow the control objective at various solar profile angle curves. This study proposed the control strategy and method that define the base control section implying the inflection point within the control objective zone and subsequently, divide the control sections for the residual time zones. The proposed strategy and method are found to increase the incoming daylight and solar irradiation by 0 to 15 %.

The objective of this study was to investigate the mono-crystalline photovoltaic modules and poly-crystalline photovoltaic modules characteristics of power reduction and quantification of performance depending on the shading. In order to determine the shading performance quantitatively, coefficient of shading performance, CSH, were proposed by analyzing the generation performance and explaining the regularity according to the shading location and area, which followed PV module examinations in STC(Standard Test Condition) of IEC(International Electrotechnical Commission). Proposed performance index can be sufficiently utilized to increase the accuracy of predicting the effective PV module generation for designing the photovoltaic system in practice.

Many countries are making nationwide efforts to lower the environmental impact of building by reducing the building energy consumption. Korea has recently enacted new green building regulations. According to this building regulation, energy performance must be accompanied by certificates in business. The purpose of this study was to consolidate the new certification system firmly with a reflection of domestic condition and public confidence. To achieve the task for this study, we have investigated the energy performance certificate that is currently being implemented for building energy efficiency improvements in Europe. Also we have analyzed EPC by investigating the current status and items of EPBD by BPIE. Based on the analysis, we proposed some ideas for vitalize the energy consumption certification domestically.

In this study, the new theory on ‘solar profile inverse function’, g(y), was defined for calculating the time(s) corresponding to solar profile angle. And the blind control algorithm with ‘solar profile inverse function’, g(y), and ‘solar profile function’, f(t), was proposed to improve the control performance. Within the boundaries of ‘optimum time interval’, ‘minimum time interval’, ‘maximum time interval’, ‘minimum blind movement’ and ‘maximum blind movement’, control algorithm with immediate decision of time and solar profile angle variations was proposed by using ‘g(y)’ and ‘f(t)’ without numerous iterative process. Through the implementation of proposed algorithm, concision, rapidity and accuracy of control could be improved. And then, the proposed ‘solar profile inverse function’ can also be utilized effectively in various field such as analysis of solar geometrical characteristics.
