Gentlemen:
During early 1979 control improvements were carried out by your firm on a number of our schools. These schools are listed on the attached schedule which indicates the savings that have been achieved.For clarification purposes, it should be noted that:

  1. a) no allowance has been made for the fact it was 4.7% colder in 1980 than in 1979.b) The
    utility costs are 1979 actuals and no allowance has been made for escalation.c) The
    majority of the savings are undoubtedly higher as the modifications were not in effect for
    the entire year.d) We have assumed only 75% of the actual gas and electricity savings
    because of the sliding scale rate structures.
  2. e) Approximately $17,000. Is included in the cost of improvements at West Hill Collegiate for other work that was performed at the time aimed primarily at improving poor environmental conditions.

It is almost needless to say that we are very pleased with the results and the manner in which they were carried out.Yours very truly

J.R. Mazanik
