Summary
The beginning portion of the final report contains an analysis of the existing National Law Enforcement Museum. The next portions are mechanical depth analyses of a pavilion façade redesign and a mechanical redesign into a variable refrigerant flow system. The final parts of the report contain two breadth analyses of a reverberation time calculation of the Hall of Remembrance and a daylighting study of the pavilion.Mechanical Depth | Pavilion Facade Redesign
Taking into account the massive load on the building mechanical system from the glass loads, the façade of the building’s pavilions have been redesigned to contain an opaque roof and a curtain wall with a higher u-value. This will reduce the building’s energy cost during the cooling months but slightly increase it in the heating months because there will be less solar gain to offset that load.Mechanical Depth | Variable Refrigerant Flow System
A VRF system was chosen as the redesign method because these types or systems are expected to use less energy, make less noise and to be more efficient. The redesign is evaluated against the original variable air volume system and is determined to have overall lower energy use, heating & cooling loads. An RS Means cost evaluation of the system showed an increased first cost of $40,000 from the original design. Evaluating this value for the life-cycle of the system showed that it would not be a good investment.
