Lighting Depth   Original Posted 12/12/14

The lighting of four unique spaces in the BCJC will be redesigned. The designs will adhere to the criteria that were developed in Tech Report 2. These criteria include qualitative functional aspects such as way finding and security and quantitative aspects such as illuminance levels from the IES Handbook and power density requirements from ASHRAE 90.1. The completed designs will be documented with lighting plans, lighting schedules, illuminance calculations, and renders. For each of the spaces changes will be implemented based on the comments from the presentation at Lutron. The four spaces are as follows:

Outdoor Space: Main Plaza
Circulation Space: Main Lobby 1000
Large Workspace: Open Office 2520
Special Purpose Space: Ceremonial Courtroom 4100

    
 
Electrical Depth    
The electrical depth has three portions. The first portion is making the required changes to the electrical system in order to accommodate the redesigned lighting systems. This includes wire, conduit, breakers, and panelboards. The second portion is performing a coordination study of the electrical system. The final portion is performing an analysis of using a DC power distribution system. The first part of this analysis will be to conduct research into studies that have already been performed and what steps can be taken to optimize a dual distribution system. Research will also be performed to see what devices are currently available that can utilize DC power. The most likely devices to utilize DC power are motors, severs, telecommunications equipment, and LED lighting fixtures. After research is performed a study will be conducted to investigate the changes in operational, maintenance, and first cost as well as changes in equipment space requirements that will occur for a DC distribution system to be utilized in the BCJC.    
 
Acoustical Breadth    
For the acoustical breadth an analysis will be performed of the RT of the ceremonial courtroom. This analysis will involve deciding what range of RT is acceptable for a courtroom, modeling the space as currently designed (including geometry and materials), calculating the RT of the space, and making recommendations to improve it as required.    
 
MAE Depth    
For the MAE depth skills that were learned in ACS 597E will be utilized to investigate the effectiveness of the sound reinforcement system in the ceremonial courtroom. The geometric model will be imported into Odeon and an acoustical analysis will be performed. The analysis will determine the audio level and distribution that would occur when sound reinforcement is and is not utilized. A dB plot of the room will be created for both cases. Auralizations will be created to simulate what a person seated in the public seating area would hear if a person (attorney, judge, witness, etc.) were speaking without reinforcement and what they would heard with reinforcement. Based on the results of the analysis recommendations to improve the performance of the system will be made.    
 
Mechanical Breadth    
Combined Heat and power (CHP), when applied correctly, is a means of using fossil fuels much more efficiently than the typical method of using grid supplied power and a separate heat source. An analysis will be performed to determine the practicality of applying a CHP system to the BCJC. This analysis will included performing research into studies that have already been conducted, calculating the loads that are on the building, performing a cost/benefit analysis of applying a CHP system, and determining how to integrate a CHP system electrically
