Geothermal Systems that, “Work By Design, Not By Accident”

GLD2016 Update Available!


GLD2016 continues to offer more features and updated contents.

The newest design tool in GLD, the Piping System Builder, gets an enhanced fluids table for international users.  Current Metric users will also notice that there is an expanded selection of Horizontal Slinky sizes to accommodate the 32mm slinky that are often used in European markets.  We’ve included a notice to users when choosing the larger slinky pipe sizes that it is more difficult to use large slinky pipe in the field but the user now gets to choose this larger size.

In addition to the changes above, the newest installer package allows a per-user installation so that multiple users of the same machine may now select their own logos for reports.  This is in addition to each user now having their own unique storage location for all of the familiar subfolders for projects, zones and etc. 

Network administrators will now have the ability to distribute software to network users with the new installer that permits system level permissions in addition to the user level permissions.

Latest build number:  GLD2016 v9.0.62 for both Stand Alone and Network

NOTICE to current GLD2016 users:  Due to numerous software updates in this release, we highly recommend that this update should be applied as soon as possible!

The Piping System Builder

The fully automated Piping System Builder performs a full piping build-out, complete with balancing valves, purging optimization, system efficiency analysis and a piping bill of materials!  There is no other program in the world that can do this for the designer.  What used to take hours of time with spreadsheets, specification sheets and frankly, guesstimating, can now be done precisely in a matter of minutes. With the Piping System Builder, design systems with a level of detail and accuracy that can make the difference between an efficient, cost effective system and a system that underperforms or fails.

GLD2016 Ready for Windows 10

Microsoft has now completed the free Windows 10 roll-out and many of our customers are converted to W10 Professional.  Fortunately, GLD2016 has not had any significant issues and support calls have not been related to the new OS.     

Please note:  Versions of GLD prior to GLD2014 build 8.0.11 will NOT play well with Windows 10 due to OS security issues.  Tech support is available for GLD2014 and 2016.  Earlier versions are no longer supported and should be upgraded.

Previous GLD Versions

Users of previous versions of GLD may want to consider upgrading to the current version as support for versions prior to GLD2014 is no longer available and moving forward, the older software may not work at all on the newer Windows.  Upgrade paths are available for GLD2014 and GLD2012.  As an incentive to users of GLD2010 and earlier, we are currently offering a discount credit towards the purchase of GLD2016.

Online Tutorials Available at the Ground Loop Design Website

In addition to the 400+ page user manual, there are GLD user tutorials and recorded webinars available from the website.   If you are a new user or just looking for a quick refresher, there are videos of topics ranging from initial overviews to more in-depth topics such as designing with hybrids and utilizing hourly load data.  Additionally, there is a series of “Skill-Builders” to help you take your designs to the next level.
