Thedesignforourgroup’ssanitat ionmodulewas

inspired by an analysis of a sanitat ion system

located on campus. The intent of the design

was to establ ish a system that was capable

of maintaining i ts funct ional purpose whi le in

ELECTRICALMODULE

The basic design of this building is dependant upon the need for higher levels of sopply and output both in the case of an emergency and withregards to the overall electrical demand. The system branches from the city’s electrical lines to a main transformer, located at the corner of Mercer Road and Alimni Drive. From this transformer the line runs blow grade into a smaller transformer located on the west side of thebuilding, designated for the Stroh Center’s use only. Then from the on site transformer the line runs into the main electric system (a) from below grade using metal turnups (b)then is distributed through panels (c) which in turn serveces the building by zones. Then the power is distributed accordingly to the required curcuits withineach interior space. The Stroh Center also offers zones. Then the power is distributed accordingly to the required curcuits withineach interior space. The Stroh Center also offers available emergency shut down by these zones which in turn offers the ability to turn off power in aparticular zone, without disturbing the power of other areas of the building allowing for construction work or repair possibly required on certain areas of the system.

We also observed that the demand for speedand accuracy was off critical concern. The desired task background reeectance was estimated between 50% and 60%. Our lamp selection resulted in the implementation of T-8 lamp type and color. The basic work planewas set at 2.5’ above eoor level.

We believe this will be accommodated for through using 2 lamps per luminaire and suspending them 1.5’ from the ceiling. The desired reeectance levels are as follows; ceiling reeectance is 80%, the wall reeectance is 50%, and the eoor reeectance is 20%. After assessing the levels of possible light loss factors we calculated that the overall total light loss would be an estimated 58%. The overall design was setupon a 4’9” spacing between luminaires, creating a row of 5 total luminaires in the direction dimensioned at 48’. The distance between the nal luminaire and the opposing wall measures 3’8“. In the opposing direction bby which is dimensioned at 64’, we found the desired light level could also be accommodated by 5 luminaires but with an interval spacing of 10’. This arrangement leaves a 5’9” space between the far wall opposing the door and the nal luminaire to make sure the deepest part of the space would be accommodated for. The side of the space the door lies on we felt deserved a more transition oriented lighting arrangement by which hold a xed spacing of 8’8” between the wall and luminaire. This allows for slightly dimmer levels, by which the change between in illumination between spaces is accounted for.

The design of this thermal system is based on minimizing duct work while still providing comfortable room tem-peratures of 75 degrees within each space. The main register used throughout this system is a center placed ceiling register. The system begins with the cooling components placed in the mechanical and electrical room. The main vent runs to the hallway from there it runs perpendicular along the center of the hallway ceiling, along the way one 2-way register is used to accommodate the janitor closet. Continuing down the hallway the system is designed to service both the men’s and women’s restrooms through the use of one 2-way register each. Before turning again the main vent deposits 7 4-way registers throughout the main vertical circulation space and café gathering area. The main vent deposits 7 4-way registers throughout the main vertical circulation space and café gathering area. The system then continues into the corridor braching into two office spaces and an inpatient room, all of which required two 4-way registers. A 3-way register is set into the re escape stairwell, an enclosed space, the intent of which is to provide a continuous airrow vertically within the space by establishing a more directional row. The main vent turns once more and accommodate four different spaces all of similar dimensions through the use of two 4-way registers. These spaces are basic functional spaces intended to be used as both exam and office spaces. The return system is situated along the entire main vent to reduce the amount of inaccessible spaces in the ceiling system. The intent situated along the entire main vent to reduce the amount of inaccessible spaces in the ceiling system. The intent being to minimize thermal venting material used, this system established a main vent located above the common spaces and continuing along the corridor. With a system that situates itself evenly between all accommodated spaces, it allows itself direct vent branching from the main vent to center placed ceiling registers situated within each space.
