All CFC (R11 and R12) and HCFC (notably R22 and R123) are being phased out by the Montreal Protocol that many nations have adopted as law.  The phase out does not mean that they will disappear completely as enough gets produced by the allowed levels in the protocol for equipment service. 

The phase out has several consequences, mainly, the sharp increase in the cost of refrigerant that are no longer mainstream (such as R22 for whom no equipment will be manufactured after 2010). This increase should be accounted in the operational budget in the facilities that use them.

R123 (used mainly in centrifugal chillers) will be not be phased out until 2020 and then, with the stocks that will be allowed to exist for maintenance, should be available until the machine that uses it becomes obsolete.

The  future refrigerants will be geared towards environmental friendliness. However, these new refrigerants will have a negative impact in HVAC equipment efficiency.  This impact is expected to be offset partially by improvement in design and manufacturing technology of the equipment itself.

Savings on Water Charges:
OUC charges you rates for your irrigation based on “irrigatable acreage”. If you have not provided them with the correct acreage of landscaped area, they will charge you for

the higher rates. Once we got our information corrected in their system, our monthly irrigation bills decreased by as much as 40% on some properties.

For example, if OUC has you in their system as a 1 acre sight but you actually are irrigating 5 acres, you are being charged way too much, because their system thinks you are

using too much water for that 1 acre. Ask your landscapers to tell you how many s.f. they are maintaining – they usually know it down to the exact s.f.!!

Also, OUC will perform an irrigation audit for your property and provide feedback on the current conditions (number of zones, the amount of time each zone runs, etc) and give

you guidance on zones that run too long or too often. This service was provided free of charge when we had it done in 2005.

Lastly, and most certainly the GREENEST, don’t forget to install and maintain those rain sensor gauges on your irrigation system. No reason to irrigate when it’s been raining 2” every day for the last month!!
