Anderson Hall is predominately an administration building which caters to a
smaller population traffic level than Rinker Hall, and contains no research or teaching
laboratory space. As shown in Table 4-1, total building horsepower for Anderson hall is
approximately half of the peak ratings for Rinker. These qualifications give insight into
the results shown in Figure 4-15. Over the 20 year life-cycle presented above, Anderson
Hall utility costs total out to $817,428, approximately 2.2% below Rinker Hall's
$835,748. Due to this difference, expected payback period cannot be calculated as the
model would never make up for the initial up-front costs and the gap would increase
annually. The S.I.R. for the above comparison is -.028, showing a theoretical negative
return on investment. When related to square footage, Anderson Hall costs are equal to
$17.12/sf over the twenty year life span, $.84/sf lower than that of Rinker Hall. In
following traditional LCC methods of thought, Anderson Hall would prove to be the
more cost efficient building, however the above qualifications still lend credibility to the
design efforts present in Rinker Hall. Results are still quite profound and in favor of
Rinker when the complete facts behind the complexity of building systems are taken into
account.
