Wallace Library Redesign for Usability

Compiled by students in Design Project Management Spring 2013

Individual- Leisure: Number of CouchesDirection Units Marginal Value Target Value

↓ Couches 1.5 0

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 ChairsDirection Units Marginal Value Target Value

↑ Chairs 9.5 13

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 TablesDirection Units Marginal Value Target Value

↑ Tables 5.5 10

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)

Computer Area 18 28 10 56

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 OutletsDirection Units Marginal Value Target Value

↑ Outlets 4 5

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

Direction Units Marginal Value Target Value

↑ Workstations 13 20

↑ Seats 13 20

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**

Direction Units Marginal Value Target Value

↑ % 48 100

Marginal value represents the current state of the first floor:

Chairs

Number with Cushioned Seats 53

Total 110

Cushioned Percentage 48%

Ideally, to provide comfortable workspace seating all chairs

would have ‘soft’ seats

Individual-Academic: Distance between Workstations

Direction Units Marginal Value Target Value

↑ Feet 3 6

Minimum ADA requirement Doubled the ADA requirement to allow for easy two-way traffic

Individual-Academic: Sound LevelDirection Units Marginal Value Target Value

↓ dbA 80 40

Online research suggests a typical office environment falls into this range

A loud office environment can reach 80 dbA while a quiet office environment is around 40 dbA

Our target it at the low end of this sound range, since the quiet atmosphere may be more conducive to academic work

Out of the 36 available computers, our observational data shows a maximum of 2 people using devices requiring an outlet (2/36 = 5%)

Realistically, 100% of the furniture does not need to be mobile

In order to satisfy the customer need to reconfigure the space, a

large percentage of furniture need to be mobile

75% was chosen, does that seem reasonable?
