Ammended Proposal for Spring Thesis - January 16, 2015
Mechanical Depth
The mechanical depth for the National Law Enforement Museum will be composed of adjusting the existing mechanical system into a variable refrigerant fluid system and building enlosure improvement. These systems are chosen because of their ability to decrease to energy load of the building and to reduce noise within the museum spaces. The new designs will attempt to continue the use of energy saving free-cooling during certain climate conditions. Trane Trace 700 will be the main software used to model and verify these design tactics.
Daylighting Breadth
The existing pavilion facade design allows for a very high infiltration of daylight into the space. This design places a heavy load of the building cooling system. However, the architecture is helpful in daylighting the spaces. This breadth analysis will look into whether the daylight infiltration into the space meets the criteria set by the Illuminating Engineering Society of America. This analysis will focus on the lobby spaces within the pavilions and the ticketing area. The program IES Virtual Environment will be used for this analysis.
Acoustic Breadth
The second depth topic is room acoustics which will further show an understanding of architecture and engineering, . The Hall of Remembrance is a very important portion of the National Law Enforcement Museum. It is a space that requires acoustic control because of its reverent nature. Visitors within the space should be able to converse with one another without interfering with other guests' enjoyment of the space. Therefore, speech intelligibility and the reduction of an "echo" are the most important criteria to meet. Because of this, reverberation time will be calculated to determine whether the Hall of Remembrance meets the expected criteria for speech. The modeling will be done with the Norris-Eyring and Sabine equations for reverberation time. The calculations will be done with Microsoft Excel following guidelines from Architectural Acoustics: Principles & Design.
