Re: Energy Saving at City Hall

Council earmarked a sum of $3,000 this year for
making energy saving changes in City buildings. As a
result we have had discussions with several consultants
and with the B.C. Energy Commission to review ways of
saving energy and a great deal of material has been pro-
vided by Alderman Mabbett.

One of the things that became apparent in dis~
cussions with consultants and with our own staff was that
lighting levels in the main offices were too high for
comfort as well as in terms of energy used. After dis-
cussion with my own staff as well as those of other
departments in City Hall, we came to the conclusion that
lighting could be cut by one-third to one-half without
producing unacceptable lighting levels and that, in fact,
the staff would appreciate a cut in the levels to reduce
visual discomfort. Accordingly, we have taken over 100
flourescent tubes out of service at an annual energy
saving of over 10,000 kilowatt hovrs and a cost saving of
over $300. In addition to the energy costs saved by the
reduction of lighting, we would expect that our air con-
‘ditioning costs would also be reduced because of the lower
heat generation from the lighting. The amount saved in
this way is difficult to estimate. We would also be
replacing fewer burnt. out lamps on an annual basis and
this will also result in some cost savings.

There may be a requirement for some desk lamps to
provide direct lighting on work areas that need a higher
level of lighting and the costs of these will be taken out
of the energy saving fund.
