Abstract

This project aims to design the integrated control of shading and operable windows for CEG east facade to improve the thermal comfort with respect to energy consumption. The design stage focused on the thermal advantages that the integrated control of shading and operable window brought to the CEG building. The controls are simulated in the EnergyPlus engine with DesignBuilder interface. The output data of temperature distribution and heating demand of the two proposals were used to compare for choosing the best control strategy during the operating stage. One proposal was using the old glazing materials and the other one was replacing the whole facade. After choosing the final solution (new construction), the effectiveness of shading and operable window control, the visual and ventilation performance of the integrated control, the possible energy deviation, the design refinement were conducted. The final control had a total discomfort occurrence of 39.5 hours, heating demand of 36.10kWh/m2 and lighting demand of 11.17kWh/m2. Compared with the simulation of the existing situation with new construction, it reduced 79% of discomfort hours and 38% of heating demand.
