The Children s storytelling area

Transcription

1 Purpose of Space The Children s storytelling area This area has a circular seating pattern, in different levels going up. Its intended use is for librarians, parents, or young adults to read to children. While it s not being used for storytelling in groups, it may also be used as a sitting area where children can sit and read a book. Along the south wall, there are also bookshelves where the patrons can find picture books. Lighting Concept This storytelling area has a more fun look. Its different layout and design provide a school oriented approach but at the same time make it creative and enjoyable for children. The ceiling also is composed of a circular dropped ceiling over it, which is shaped as a donut. This dropped ceiling holds color changing LED s which will create the mood with its bright colors on the ceiling. The seating area back is made of the same material as the drop ceiling which is a luminous and transparent surface which allows light to go through, and there are LED s located inside thesis back where the patrons can enjoy the color environments created by these lights. Dimensions This area has a square-like geometry, located in the north west area of the second level and has access to the family place, children s circulation and has a arched pattern in different levels in the middle where children can sit.

In the middle of the area there is a seating area that protrudes from the floor. The back part is made out of a translucent material that has 69% transparency and will glow with the LED lights inside it. The seating area is located right inside the back part and is shaped the same, allowing people to sit there when reading or listening to stories. Daylighting In this area, there are windows on the north side providing daylight and at night some light from the exterior luminairs. There are no skylights. Lighting Controls The control device used in the children s computer area of the library was the manual on/sched off (8am-10pm) type and it uses a time switch with manual switch override. This area also has a new control system that will use DMX 512 color kinetics controller in order to do the color changing with the LED lighting. Ceiling plan

In order to keep the children s interest on the area and provide a comfortable and pleasing atmosphere, the storytelling space should have an inviting and original look to it.

7 Light Distribution on Surfaces Important Light distribution on this space should be even in order for people to be able to read at ease. The storytelling area has different levels in a circular pattern, so this area needs even lighting throughout the space. Reflected Glare Very important At the storytelling area, reflected glare might be an issue since it is close to some windows and these might reflect the light coming from the light fixtures. Bare lamps should be avoided and placement of luminairs should be considered. Shadow Somewhat important There should not be shadows on this area, or kept to a minimum since children or parents shouldn t be required to move in order to have a better vision of the book they re reading. Shadow patterns would also be distracting and would provide an unpleasant view. Source/Task/eye Geometry Somewhat important The source of the luminairs in relation to the eye of the person is somewhat important, but due to the composition of the area and the ceiling architecture, the possibilities for luminair placing is a bit limiting. Horizontal Illuminance Important: lux (30-50 fc) There should be enough light on the area in order for adults to read to their children as well as for children to read storybooks. There should be enough illuminance as well in case people want to read books with fine print.

The bookshelves along the wall also provide good illuminance in order to be able to read the titles. The LEDs provide the seating area to glow in different colors. Although it can t be seen clearly using Lightscape, it should work due to the transmittance and transparency of the material (sand blasted glass). The power density was acceptable and it actually went down from the original design. So there is energy conservation as well as better aesthetic quality on this area. There were various changes in this space, since it is the most fun area in the library. This semi-square area has a circular (half-moon) shaped seating area made out of ½ sandblasted glass. This material diffuses and transmits the LEDs which are inside it as

17 shown on the detail above. This seating area back rest will glow from within and change colors as time passes by. This should be a major attraction for young kids. The circular dropped ceiling should change colors as well and hope that it also makes kids more eager to come back to the library and read.
