This online tool has been developed to help data center and facilities managers easily determine how much free air cooling and free evaporative cooling is available for individual data centers. Using zip codes, the tool allows users in the United States and Canada to input their specific variables - such as local energy costs, IT load, and facility load - to determine the energy savings for individual facilities. Other regions will be incorporated in the future.
Recently, a feedback session was held for members to provide input on The Green Grid's Free Cooling Tool and Maps. You can download this discussion and provide your own comments by using The Green Grid's Forum.
Updated Free Cooling Maps:
North American Free Air Cooling High Res Map - ASHRAE Class A2 (Member Only) North American Free Air Cooling Low Res Map - ASHRAE Class A2 North American Free Air Cooling High Res Map - ASHRAE Class A3 (Member Only) North American Free Air Cooling Low Res Map - ASHRAE Class A3
Checking the "Mixing allowed" box counts hours when the outdoor dry bulb temperature is below 59F (18C). If designed correctly, the cooling system will mix the proper amount of return air with outside air to bring the inlet temperature up to 59F.
If mixing is not allowed, it is assumed that outside air is brought straight into the computer room; thus only hours where the outside air temperature is above 59F are counted.

Can you clarify the impact of the mixing checkbox element. The results seemed to show some variance that cannot be quite understood when this checkbox is used or not

Thank you for your inquiry. The postal code you should use for Toronto is M3B 0A3.

Can we know the nearest location postal code for Montreal please?

The nearest location in our database to Ottawa appears to be K1A 0A1. Please note that data is not included for all postal codes.

Is it possible to determine the postal codes for the canadian weather stations. This way, I can choose the nearest weather station for my calculation. I need to calulate for city of Ottawa.

The tool does work for Canadian postal codes however, data is not included for all postal codes. The nearest location in our database to M1H 3J3 appears to be M1H 0A1. Both are in Scarborough, Ontario. Hope this helps!

The North American tool does not appear to accept Canadian postal codes. I've tried with and without space (i.e. M1H3J3; M1H 3J3).
The error presented each time is...
"parsererror: Invalid JSON: no data file found for that zip code"
Please advise. Thank you!

Gee, either my timing is impeccable or I was blind and now can see, I just re-loaded the tool and see the boxes for allowing mixing and humidification along with the ? buttons. Great job.

For a large percentage of the population which I believe are in the target audience (that is, non-MEs with an interest in data center free cooling), the fields of the tool are non-intuitive. Would it be possible to add pop-up documentation on the titles of the fields?
