RE: Ventilation for the Port Coquitlam Energy Centre —

Dear Mr. Mayor:

In Late October I sent you a copy of a memo I had written to
Ms. Vivian Vaughn of the Ministry of Energy regarding the
proposals for ventilation of the PoCo Energy Centre building.

These proposals were to be reviewed upon our completing an

air test of the Energy Centre which would allow us to determine.
the actual air-tightness of the dwelling. This was done and
as we suspected Earl Ramgren did an excellent job of. renovating
the house. Our air test indicates that some form of ventilation

system should be installed.

At present, our two options are either a balanced two-fan
intake/exhaust system or an air-to-air heat exchanger system.
Each would provide adequate air flow and humidity control

with the latter recovering up to 70% of the heat contained

in the exhausted air. The cost of the fan system is approxi-
mately $600 and the cost for the heat exchanger is approximately

$1000.

The MEMPR Buildings Engineer, Ms. Vaughn, has estimated that

the difference in cost between the two options would be recovered
in approximately 5 years, ignoring maintenance costs (see
attached). She reminds us that we do not know the life
expectancy of the heat exchanger, she presumes a minimum of

10 years, while the fan system should last 20 years.
