} AGENDA ATTACHMENT 111 '2 <br /> September- 26, 197_ <br /> Mr S. M. Gatti.s <br /> provide efficient insulation for winter heating but. also are significantly <br /> more effective than the existing steel sash against heat gain in the <br /> summer, thereby providing; an added reduction to the cooling load over that <br /> of the "Cool. Shade" screens alone, <br /> Based on calculations by our engineering consultants Y am informed that <br /> the replacement of the existing windows with the proposed insulating win- <br /> dows together with the "Cool Shade" screens already in the contract will <br /> give an expected total reduction in annual average energy demand of some <br /> 15„18 With only the present sash re-glazed and the "cool Shade!' screens <br /> as provided under the present contract, fuel and energy savings could be <br /> expected to be an the order of 1/3 the above figure or a 5-6% saving. <br /> The Contractor has given me verbal confirmation which he expects to back up <br /> with a written confirmation immediately, that his original. bid proposal. <br /> under Alternate C-3 offered July 12, 1977, would still be valid if accepted <br /> at this time or within a reasonably short period (say the next 2 or 3 weeks <br /> or so). lie is also urging prompt consideration so these windows can be <br /> placed on order and delivery can be made without holding up the entire job. <br /> The total cost for this substitution is as follows: <br /> Original. bid Alternate C-3 per bid tabulation, 7/12/77 $12,800.00 <br /> 1,216.00 <br /> Architect' s Fee C 9.5% <br /> $14 016_00 <br /> ' Fatal, Cost <br /> Ve truly .yours, <br /> James .11.
