  • You will be able to save your RAP settings and results on the site and print or save it as a PDF for reference.
  • The HLDN and BoM AWS data will now be updating hourly, meaning that your site data will be displayed in near real time. Note that you must be uploading your data to us in near real-time to benefit from this!
  • We will be adding some walk through videos on how to navigate some of the features on the site and how to manage your subscription.
  • Due to a lack of interest the weekly Heat Load Outlook has been removed.

These new features are just another reason to get on board with the HLDN and make the most of your site specific data. If you need a hand in setting up your HLDN data feed please feel free to contact us for assistance. As always we are available for comments and suggestions throughout the season and are happy to help.
