Everyone contributes to Sustainability at Augustana!

The Technology and Learning Services (TLS) office at the Augustana Campus, University of Alberta is currently leading the way with their energy reduction efforts. Since 2009, TLS has helped this small campus reduce its energy draw by 157 000 kWh per year.  This effort alone has saved the University $15,411.12 annually (at a rate of $98.16/MWh).  These initiatives could easily be replicated university-wide and beyond.

How have we done it?

Virtualization

By migrating our physical servers into a virtual infrastructure, we have:

  • Substantially decreased our power usage (157 000 kWh per year – the average Alberta home used 600kWh/month);
  • Decreased our air cooling demands from 21 to 17 degrees Celsius;
  • Dropped server power consumption from over 10,000W to under 5,000W;
  • Consolidated the amount of hardware required.  As a result, we have:
    –  optimized our server usage and space;
    –  saved money, as there is less hardware to purchase;
    –  reduced the amount of annual eWaste, as there is less hardware to dispose of when the technology needs to be refreshed;
    –  decreased our space usage from 3 server rooms to 1.

Note: In one year (from 2010 to 2011) we have increased the number of virtual servers by roughly 26%, however power consumption has increased by less than 1%.

More efficient Desktop Computers

As an Academic Institution we have a lot of desktop computers for our faculty, staff and students.  In 2009, our TLS staff started testing computers for energy efficiency.  Now, our computers are replaced on a 4-year cycle with some of the most energy efficient computers on the market.  In 2009, our 2005 models, which used 145Watts per hour, were replaced with 2009 models that required only 58Watts per hour.  Multiply this by 75 computers and the savings are considerable!  With new and improved Desktop efficiencies on the horizon, we will see a greater reduction in our Energy footprint every year.
