The lighting depth will be focused on the redesign of four proposed spaces: performance hall, performance penthouse, main lobby, and courtyard. The main concept of lighting design comes from the architect’s intent and the mission of the Logan family. The main goal of lighting design aims to provide various lighting scenes with lighting control to support different performance activities. In addition, new lighting design will integrate daylight into the space to increase natural atmosphere along energy saving. The design criteria will be referenced and specified from the IESNA handbook and ASHRAE 90.1.
The electrical depth will be focused on the energy and cost saving by alternate efficiency materials. Emergency generator, main circuit breaker for distribution switchboard, and dry-type transformer will be conducted. In addition, the branch circuits with protective device for the four spaces as re-designed in lighting system will be conducted.
A reverberation time and Sound Transmission Class (STC) analysis for the performance hall will be conducted to provide better sound system to the audience because the space is critical acoustically for various performances. A reverberation time will be determined how the space dose fuctions acoustically well. The Sound Transmission Class values will be calculated for the existing materials of the performance hall. If the value of STC of some materials is necessary to be modified, the changes will be made with acoustical equipment such as sound absorbers.
Since good estimates of the corresponding heat transfer rates are necessary to design an acceptable air-conditioning system, the heating loads thru the glass of the corridor on the first floor and the performance penthouse will be analyzed because those spaces are applied with large amount of windows. Each space will be conducted for the amound of solar heat gains and cooling loads with different seasons and time by a graph and table. Also, the cost saving and expenditures will be calculated if the glass type is modified.
