Cloud systems are efficient models that can utilize various infrastructures, platforms, and applications regardless of the type of clients. This paper proposes a cloud-based integrated development environment (IDE) for robot software development which would make software development easier. The proposed system provides robot simulation to test the robot HW modules or robot systems for development and testing of software operating in a robot system with two or more different operating systems (OS) such as Windows, Linux, and real-time OS. This paper implements and evaluates the proposed system using OPRoS [33].

In case of newly constructed office buildings, the construction types of their vertical envelope are almost curtain-wall system or high WWR. These kinds of buildings have problems with energy efficiency. So, national regulations on building energy efficiency have been established, but the regulations focused on the U-value, air leakage and SC of window. The building which have large windows on their vertical envelopes is influenced by solar energy. Therefore, window’s optical properties; SHGC, VLT are important factors for building energy. In this study, the correlation between glazing performance(U-value, SHGC and VLT) and energy consumption in office buildings was analyzed with simulation. EnergyPlus was used for building energy simulation. The main results of this study are as follows; 1) As U-value is decreased, heating energy is decreased within a range of 34.3% and cooling energy is increased within a range of 10.1% . And the sum of heating, cooling and lighting energy is minimum at U-value 1.20 W/㎡ ℃. 2) As SHGC is decreased, heating energy is increased within a range of 28% and cooling energy is decreased within a range of 29%. And the sum of heating, cooling and lighting energy is dramatically decreased, because the change of cooling energy is greater than heating energy. 3) As VLT is decreased, the increment of heating energy and the decrement of cooling energy are alike.

Recently, it has been concerned about overconsumption of the energy use of the newly-built curtain wall buildings with a large WWR(Window to Wall Ratio). However it is estimated that the influence of the window area on energy is changed according to the building size, preferably, WFR(Window to Floor Ratio) is correlated with building energy. EnergyPlus is used for a building energy simulation in this study. The results of the simulations show a building energy is relative to WWR, but there is a limitation to use for the index because of the building size. However, building energy is mostly relative to WFR, the correlation of this can be expressed a linear equation. Therefore, developing synthetic index according to WFR is acutely needed. And, in case of the solar gains according to a window area, the correlation can be expressed a logarithmic function, the more WWR become the more solar energy gains. The solar gains are about 5.04~5.40 times as large as an annual horizontal global radiation. If the synthetic index is developed through analysis of glazing performances(U-factor, SHGC, VLT), the index should be used for the window design of buildings.

This study focuses on thermal performance variations according to insulating glazing units and the set point temperature. We used the EnergyPlus rating, which is validated by the U.S. DOE. The results are as follows: In the case of a non-extended-type household: (1) The influence of SHGC rather than that of U-factor was found to be relatively high. Therefore the composition of glazing that may maintain SHGC at 0.5 or greater is deemed to be more desirable for energy savings. (2) When the manufacturing method of Low-e glass varies, the influence on the building energy consumption can change. Therefore, the designer is required to understand the composition of glazing in advance at the planning stages of the building. (3) In the case of Low-e insulating glass and Low-e triple glass, almost no difference exists between the influences of such on the energy demands of the building; however, Low-e insulating glass is deemed to be more reasonable from the economical aspect. In the case of an extended-type household: (1) The entire energy consumption increases in this case as compared with a non-extended-type household (2) In the case where a window faces the outdoor air, unlike a non-extended-type household, the U-factor and SHGC all have great influence on the building energy consumption, and therefore the construction of glazing in consideration of this is desirable. Lastly, as the set point temperature increases/decreases by 1℃, cooling/heating loads were found to increase/decrease by approximately 16% representing that the change in living patterns greatly influences on the reduction of building energy consumption. Further comprehensive studies on the influence of change in set point temperatures on the consumption of building energy should be conducted based on the expanded scope such as a block, unit complex, or district unit in order to recommend the method for reducing energy in apartment type housing.

Therefore, developing synthetic index according to WFR is acutely needed. And, in case of the solar gains according to the WWR, the correlation can be expressed a linear equation, the more WWR become the more solar energy gains. If the synthetic index is developed through analysis of window performances(U-factor, SHGC, VLT), the index should be used for a design of the low energy buildings.

The office buildings with the curtain wall structure are weak in the cooling load, because of the high frequency of usage and the high interior gains during a day. Controlling Window to Wall Ratio and applying low U-factor windows are used to improve this, but they have the limitation of the improvement. In this study, a building energy simulation was conducted. And the influence on the energy performance was analyzed according to Window to Wall Ratio(WWR), Visible light Transmittance(VLT), Solar Heat Gain Coefficient(SHGC) and U-value. The results of this study are as follows; 1) WWR can be an independent index of energy performance of the office buildings with dimming control system. 2) As SHGC of glazing is higher, cooing energy is increased, heating energy is decrease. And total energy is increased. That is the change of SHGC more influence on cooling energy than heating energy. 3) As SHGC of glazing is lower, the turning point of cooling and total energy in a high WWR. And the energy reverse is occurred when WWR is so low. That is increase of lighting energy is higher than decrease of cooling energy, when WWR is so low. 4) The planning for energy saving of office buildings with dimming control system is considered SHGC and VLT first and WWR after.
