January 10th, 2009: Gaia Geothermal is pleased to announce the release of GLD^TM Premier Financial 2009 Edition. The new edition includes a financial module that offers a range of financial and emissions analysis tools. These tools enable designers to quickly analyze the annual and lifetime energy costs, emissions costs, maintenance costs, installation costs, lease value opportunity costs and salvage values of their geothermal designs. In addition, users can compare their geothermal designs with up to 5 standard HVAC systems (chillers, boilers, air source heat pumps, etc) to clearly demonstrate the benefits of "going geothermal."

For a limited time, we will be offering the upgrade at a reduced price. Click here to learn more about the newest features. Click here to purchase immediately.
