Mezzanine Youth Area:

Transcription

1 Mezzanine Youth Area: Overview of Space: This is located as a shorter level on the Northeast corner of the building, between the ground and second levels two levels have been placed. The design is to allow the children using the facility to be more comfortable in their surroundings. Existing Room Description: Floor: Slate carpeting Reflectance: 0.30 Walls: Gypsum Board, Harbour Blue (or) Custom transparent satin finish, Red, Green, Purple, & Blue Reflectance: 0.60 Ceiling: Gypsum board white painted ceiling; Flat finish (or) 2 x 2 ; Superfine 9/16 ; Fine line grid Reflectance: 0.80 Ceiling height: 8-0 Page 26 of 57

2 Furniture description and layout: The stacks are located through out the floor plan. The two reading areas are located first in the Northeast corner of the space and the second in the center of the space below the elevator shafts. These elevator shafts run only between the youth area main and mezzanine levels. The focus of the redesign will be the circled reading area within the youth level. Design Criteria: IES: Library Book Stacks - Active Very Important: Vertical: 300 lux Degradation factors important to consider Important: Color appearance and color contrast, Direct glare, & Reflected glare Library Book Stacks - Inactive Very Important: Vertical: 50 lux Degradation factors important to consider Study Desks Very Important: Horizontal: 300 lux Direct glare, Reflected glare, Source/task/eye geometry Title 24: Library Stacks: 1.5 W/sq.ft. Library reading: 1.2 W/sq.ft. Evaluation of Criteria: This space is designed for children; therefore lower light levels would be necessary for the same task as those specified in the IES handbook. However with adults also reading with the children it will be necessary to allow for different light levels throughout the space. This will be accomplished casting an even luminance on the floor for children to read and sufficient light levels on the couches and chairs for adults to read with the children. Page 27 of 57

3 Schematic Design: In the ceiling slits will be incorporated with LEDs to fill in the room with a whimsical light and color pattern without being overwhelming to the space. Pendant lighting will provide lumen levels for reading. For the final design of the youth reading area of the library a more minimal design will be used, while still maintaining a whimsical feeling. This will allow for the children using this area to become comfortable in there surroundings and give a sense that it is separate from the main stack areas in the library. Page 28 of 57

4 Final Design: Design I: Is to give the room distinction by using pendants and ceiling mounted halogen fixtures to accent the room and give dimension to children s reading area. Allowed: Reading Area = 1780 sqft x 1.2 W/sqft = 2136 W (10) ERCO Starpoint Pendant Downlight (19) ERCO Starpoint Downlight Lamp 50 watt low-voltage halogen LLF = 0.7 Actual: 29 lamps x 50 W = 1450 W 1450W / 1780 sqft = 0.82 W/sqft Page 29 of 57

6 Design II: Is to give the room distinction by using semi-circular pendants that incorporate indirect light and halogen accents in the room in order to accent the room and give dimension to children s reading area. (10) Visa Lighting Infinity Pendant Indirect with (2) 24 watt T-5HO mini bi-pin base and (3) 50 watt low-voltage halogen (CP3778-4FS24-50MR16(120V)-GAL-SAL) LLF = 0.75 Allowed: Reading Area = 1780 sqft x 1.2 W/sqft = 2136 W Actual: 10 fixtures x 198 W = 1980 W 1980W / 1780 sqft = 1.11 W/sqft Page 31 of 57

7 Conclusion: The purpose of the lighting concept was to allow for areas of the room to have higher illumination on the couches and chairs sufficient for adults to read and lower illumination on the floor to allow the children to comfortable read. The first design allows for thesis lighting levels while casting an even illuminance across all planes. The second design layout allows causes areas of the couch and the floor to be both sufficient for reading by adults and children, but with this design there are very bright spots on the floor and ceiling. The first design is recommended for use in this space. Page 32 of 57
