Specification Calculations Wallace Library Redesign for Usability Compiled by students in Design Project Management Spring 2013

Individual- Leisure: Number of Couches DirectionUnitsMarginal ValueTarget Value ↓Couches1.50 There are currently 3 couches on the first floor of the library. Our assumption was a 50/50 split between academic and leisure use. In an effort to give spaces an ‘identity’ – and allow students to know the purpose of the space – the number couches should decrease because it doesn’t make sense to have furniture that can seat multiple people in an individual area. Providing group-like seating in an individual area may result in group use.

Individual- Leisure: Number of Chairs DirectionUnitsMarginal ValueTarget Value ↑Chairs9.513 There are currently 19 soft chairs on the first floor of the library. Our assumption was a 50/50 split between academic and leisure use. Target increase of 30% from the current level

Individual- Leisure: Number of Tables DirectionUnitsMarginal ValueTarget Value ↑Tables5.510 There are currently 11 coffee/small tables on the first floor of the library. Our assumption was a 50/50 split between academic and leisure use. Target to have 75% of leisure chairs with a table. From previous slide target number of chairs is 13 ( 75% of 13 is about 10)

Individual- Leisure: Number of Outlets DirectionUnitsMarginal ValueTarget Value ↑Outlets45 Current Outlet Observations Permanent & Accessible Permanent & Not Accessible Available with Power-strips Total Idea Factory Circulation Private Workspace6006 Computer Area Assumed Idea Factory, Circulation, and Private spaces are currently used for leisure, which provides at total of 51 permanent & accessible outlets. Data collected shows 41 % of observed patrons in these areas were working individually ( ~ 21 outlets) Assuming an 80% of patrons are using the library for academic purposes and 20% are leisure users: marginal outlets for leisure users is 20% of 21 = 4.2 (rounded down to 4)

Individual- Leisure: Number of Outlets DirectionUnitsMarginal ValueTarget Value ↑Outlets45 Assumed Idea Factory, Circulation, and Private spaces are currently used for leisure. Data collected shows the maximum needed observed outlets for all of these areas as 57. Data collected shows 41 % of observed patrons in these areas were working individually ( ~ 24 outlets) Assuming an 80% of patrons are using the library for academic purposes and 20% are leisure users: target outlets for leisure users is 20% of 24 = 4.8 (rounded up to 5)

Individual-Academic: Number of Workstations & Seats DirectionUnitsMarginal ValueTarget Value ↑Workstations1320 ↑Seats1320 Assumed Circulation, Idea Factory, and Private Workspace are currently used for individual-academic work. Data collected shows 25% of observed patrons in these areas were working individually. Currently there are 101 seats in these areas. Assuming 1 seat = 1.5 workstations (due to the area students occupy with books and notes while doing hw) that is about 17 current workstations in these areas Assuming an 80% of patrons are using the library for academic purposes and 20% are leisure users: marginal workstations for academic users is 80% of 17 = 13.6 (rounded down to 13)

Individual-Academic: Number of Workstations & Seats Assumed Circulation, Idea Factory, and Private Workspace are currently used for individual-academic work. Data collected shows 25% of observed patrons in these areas were working individually. If the maximums observed occurred simultaneously there is potential for 148 patrons in these areas at one time. That is 37 workstations. Assuming an 80% of patrons are using the library for academic purposes and 20% are leisure users: target workstations for academic users is 80% of 37 = 29.6 (rounded up to 30) ** Target workstation styles are for individuals, so the 1.5 weighting is not applied here** DirectionUnitsMarginal ValueTarget Value ↑Workstations1320 ↑Seats1320
