It has been interested in appling smart window system to buildings in order to control solar transmittance by active way. The performance of control strategies on the smart window system, especially electrochormic window (ECW), have not fully evaluated in the perspective of building energy consumption. The presented article provides potential control parameters and logics to operate ECW. It also evaluates building energy performance by the developed ECW controls conducting annual building energy simulation for a medium size office building model. Five control parameters are derived from time scheduling (SPC), solar irradiance (IRD), outdoor air temperature (OAT), cooling demand (CMD), and room air temperature(RAT). Each control parameter has ranges or target values to activate ECW operation. The result shows the control methods can avoid solar transmittance by 90% thorough South, East, and West in the highest solar radiation day in Inchoen, Korea. ECW operation can reduce cooling equipment sizing by 20% in approximation and save annual HVAC energy consumption ranges from 11.22% to 20.70% by the control methods. The RAT would be the most effective control parameter from this study because it outperforms other parameters on annual HVAC energy saving and investment of system installation.

Quality control is a management to do 'right things' in 'right ways' when producing goods or services to satisfy customers. But current quality control has been concentrated on only right ways rather than right things. Though quality control activities have been made to judge whether procedures are followed or not, they could be worthless without considering what customers want. This kind of quality control method was appropnate when customers' choice was limited on products supplied by mass production company. Unlike mass production system, the customers in mass customization system have various needs. But the adaptation of current quality control is much dulled to the changes of customer needs. So It has caused many problems in this customer-centered business environment. Therefore this study suggests new quality control method to solve the problems of current quality control method which is not suitable to mass customization. New quality control method using construction value can respond to continuously changing customer needs promptly. It can achieve a quality improvement by total plan which current quality control was hard to make. It also can compliment current quality control by shlfting the focus of quality evaluation from the accomplishment of jobs to the quality improvements. If we develop new quality information system based on construction value, it will provide more advantages to quality managers than current quality information system mainly storing information of flaws do.

Recently as well as improving the standard of living people can not only save on heating and cooling loads are increasing the demand for pleasant air in the room. In addition, public housing and ventilation of multi-purpose facilities of the rules regarding such equipment based on the revised building in 2013 House of Commons to stretch by 0.5 times per hour, etc. equipment standards: the mandate was natural ventilation or mechanical ventilation installations to be made over ventilation (ACH 0.5 / h). Total heat exchanger of the plate type mechanical ventilation equipment in order to solve this problem has been growing concern because of the characteristics that can recover all of the decrease in the air-conditioning load, and sensible heat and latent heat with room ventilation. But the lack of verification of the status of the heating and cooling load increases or decreases in accordance with the heat exchanger. In this study, using a EnergyPlusV8.-4-0 Dynamic energy simulation program to evaluate and compare the annual energy installation according to the presence or absence of the heat transfer plate heat exchanger is installed in an enclosed living space of the nation"s public housing apartments.
