Architectural Program A gutted existing industrial building with a foot print of 8,833 ft2 is located on a 3+ acre lot was desired to be reconditioned into a public library in Nobles, In. The new library was to be aesthetically pleasing as well as ADA accessible . The first floor needed to include the following: Entry and Circulation Desk area, Children’s Help Desk, Open area for stacks (shelves of books and media) and computer terminals, Public restroom, Head Librarian’s office, Staff workroom/ kitchenette, Staff restroom, Two meeting rooms, Noblesville History room, Mechanical room, faculty, stack space, children’s area, waste removal, and additional exterior storage. The 2nd story covered level needed to include an open floor area for stacks and a public restroom. A new modern entryway and vestibule needed to be added to provide improved modern aesthetics, provide full ADA accessibility, and an inviting way for guests to enter the building.. The exterior of the building also needed to provide a weather shielding area for patrons to enjoy being outside while sitting and reading while being protected from the elements. The site borders a highway to the east, as well as two main roads to the west and south, providing convenient access to patrons. Adequate storm water reconditioning was met with a(n) intensive green roof requiring a soil depth of 4”which allowed the use heavy vegetation as well as a retention pond. The non-existing wall leading from the second story stacks to the green roof was chosen to be a curtain wall in order to provide natural lighting. All structural components were checked and modified to meet the need occupancy classification and modifications of the new intended use. The low slope roof on the second story was chosen to be a green roof because water runoff. The concrete floor system on the secondary stacks was chosen to be a type cast-in-place. Building construction code research The building was classified as an Assembly A-3 (IBC 2009 Section 303.1). From IBC 2009 Section 602, the wall leading to the green roof could be type I,II,II,IV or V From Table 1004.1.1 the floor area required per occupant is 100 sq ft (gross) for stacks and 50 sq ft (net) net for reading rooms. This gave an occupancy of 177 people on the 1st floor, 88 occupants on the green roof, and 55 occupants on the 2nd story reading room. This gave a total of 311 occupants in the building. Per IBC Section 1005, “The total width of means of egress in inches shall not be less than the total occupant load served by the means of egress multiplied by 0.3 inches per occupant for stairways and by 0.2 per occupant for other egress components. Multiple means of egress shall be sized such that the loss of any one means of egress shall not reduce the available capacity to less than 50 percent of the required capacity.” Egress from the ground floor must provide egress for all occupants. Required total main floor egress width = 72 in. Required stair egress from 2nd floor stairs = 32 in. From Table 1021.1 the minimum number of exits from the ground floor and from the 2nd floor is two exits. The ground floor is not allowed a single exit. From Table 1021.2, assembly occupancies may have a first story with a single exit if the occupancy does not exceed 49 occupants and the travel distance to the exit does not exceed 75 feet. Both of these criteria would be exceeded with a single exit. A total of 4 exits on the first story are required unless 2nd story fire escape exits are included. There is no allowance for a single exit at the second floor for Assembly occupancy according to IBC 2009 Table 1021.2. The site location is zones as PB = Planned Business. Per the Noblesville Ordinance, “the purpose of the PB District is to encourage well-planned business uses, particularly with respect to unified design, safe ingress-egress, adequate and properly located parking and service facilities and convenient and safe pedestrian accessibility… The PB district is also designed to service the motoring public through such uses as motels, restaurants, or service stations.” (Section 159.107 Noblesville Code of Ordinances) The maximum height is Three stories or 35 ft in height (per IBC 2009 Section 159.107). (all previous is from 3.1.2) Structural design: The 2nd story roof was based on Per Table 1607.1 of the IBC 2009, the required roof live load for ordinary flat (low-slope) roofs which is 20 psf. A BUR which has an assumed dead load of ~6.5 psf per the Load Span Table, using a 7 ft span and a double span. Steel decking of type 20F was chosen. This allows a total load of 47 psf. This required an open web joist type 12K1 to serve as beams. See supporting calculations in Appendix 9.1. (from 3.1.6) 2nd story floor framing calculations sized a 18x35 for an interior beam and a 24x76 or a girder see supporting calculations with shear and moment diagrams in appendix 9.2. (from 3.2.7) A square spread footing foundation footing was chosen with a side length of 90” to meet soil bearing capacity and loads. See supporting shear /moment diagrams as well as moment, deflection, and shear calculations in Appendix 9.3. (from 3.2.10) Landscaping and screening are required in interior parking lot islands, perimeter parking lot buffers, buffering for non-residential uses abutting residential uses, surrounding outdoor storage and waste disposal areas, and other situations. (Section 159.105 of the Noblesville Code of Ordinance). Energy Efficiency: The City of Noblesville has decided to propose energy efficient design and construction and will therefore require that the Keystone Library be renovated to many requirements of the most recent ASHRAE 90.12007/2009 IECC code. Which requires an Rci value > than 20 for the roof by using 5” inches of spray polyurethane foam. The second story wall fenestration to the green roof requires an R value > 2.2 which was achieved by triple-glazing the panes. The Steel framing exterior required an R value which was achieved by including R Batt 12 insulation. See supporting calculations in appendix 9.4. The estimated heat loss through the new second floor wall in the KRL leading to the green roof based on an interior temperature of 68 oF and an exterior temperature of 32 oF is ~___________ BTU/hr. This is based on deciduous trees location on the South side of the property to provide adequate summer shading. See supporting calculations in Appnedix 9.5 (from 3.3.4). A vestibule was created on the main entrance in order to regulate temperature. Plumbing Fixtures: Codes required ~3 toilets and two urinals for men’s facilities, 5 toliets for women’s facilities, 2 water fountains, and 1 utility sink. Parking Lot Design: The parking lot needed to be designed for convenient parking, traffic and pedestrian flow. Given a classification of a library and a total occupancy 311 patrons. (per Section 159.107 of the Noblesville Code of Ordinances) . Parking lot design required 1 parking spaces per 300 sq ft of library space (COO Table 9, Section 159.142 or UDO Table 10.0.3.B). Therefore the number of parking spaces should be 32. All parking lots shall be set back a minimum of 20’ from the property line abutting any street. (UDO Section 4.B.1). Assuming a 90 degree parking angle, what size parking spaces 9 ft x 18 ft per (COO Table 10, Section 159.143 or UDO Table 10.0.4.A). Using an aisle with parking spots on either side an isle width of Aisle width 24 feet minimum (COO Table 10, Section 159.143 or UDO Table 10.0.4.A) According to the table presented in the presentation, 2 handicap accessible parking spaces are required. (COO Table 11, Section 159.144 or UDO Table 10.0.5). A convenient delivery location should be located near a service entrance. 5% of the parking lot pavement area must be maintained as landscape area including islands and peninsulas. All trash receptacles shall be completely screened by a wall on three sides matching the material and architecture of the primary structure located on the parcel. The fourth side shall consist of a metal gate or other similar materials completely hiding the trash receptacle. The enclosure must measure a minimum of six feet in height or two feet above the height of the trash receptacle, whichever is greater. Trash receptacle enclosures shall not be located in front of any building, adjacent to a collector, arterial, or expressway, or adjacent to any residential use. See supporting calculations in Appendix 9.6. Landscaping is required on three sides of the enclosure and shall include evergreen understory trees at three feet on center or evergreen canopy trees five feet on center, and a minimum height of six feet. (Section 159.187) Storm water design: Given the required volume of storm water storage may be calculated using the Rational Method and based on the runoff from a 10-year return period storm.” (STSM 302.03), the pre-runoff based on a meadow was 3.7 cfs and post development runoff would be expected to be ~___________cfs. See supporting calculations in appendix 9.7. This requires a total retention volume of ~___________acre-ft , which based on a circular pond to 4ft average depth would require a radius of ~___________feet. See supporting calculations in appendix 9.8 (from 3.4.5) Detention/Retention basins and ponds shall be landscaped. Such landscaping should include shade and ornamental trees, evergreens, shrubs, hedges, turf, groundcover, and other plant materials. (Section 4.A.9)
