Temperature and Climate Data Around the World

One of the issues that affects the efficiency of data centers is the climate in which the data center is located. A well-run data center in Phoenix could draw more power than a poorly run data center in Toronto. When looking at measures of data center efficiency, it's important to consider these factors.

There's a nifty utility available from UCLA called Climate Consultant (see or This software allows you to draw
psychrometric charts, plot average/min/max temperatures, etc. for any location for which you have the proper type of weather file. For example, the graphic at the right shows a psychrometric chart for Hillsboro, Oregon.

Not only is this utility free, you can get weather data for many locations for free. The U.S. Department of Energy (DoE) maintains weather data for over a thousand locations around the world, including most airports at For example, provides data for several sites in Oregon. Just save the .EPW file to your local hard disk, and you're good to go.


P.S. Thanks to Pasi Vaananen for the pointer to this tool.

Welcome to My Blog!

This is the inaugural posting to my blog. I hope this will be an opportunity to share with my friends, colleagues, and acquaintances some ideas I've had running through my mind relative to technology, energy efficiency, and some ideas of how to do things better. Please let me know what you think about this and if you find the information useful--or if you need more explanation on a topic.

For those I've never met, I hope this blog provides the vehicle for a creative exchange of ideas. You'll find that I'm passionate about some ideas, and I pledge to do my best to help you see why I believe so strongly in some of these potential solutions.

A problem without a solution is just an issue that hasn't been thought about long enough. I have confidence that collectively we can come up with better ways of doing things, and we may find some breakthrough approaches along the way.

Buckle up, it'll be a fun ride!
