The online HStar portal is the website that produces the Universal Certificate that is accepted as evidence a house design complies with the Energy Efficiency requirements of the National Construction Code of Australia. The AccuRate and BERSPro software send data to the portal which is used to produce the information on the Certificate.
An additional benefit of having the portal is that it retains the basic data so that analysis of what is being planned for new housing stock can be undertaken. As the database grows it will show changes to construction over time which will be useful to industry and government to optimise the delivery of better housing for Australians.
The portal has only been in operation for a short time so we can’t yet identify much in the way of trends in the data. But we have some interesting information to share such as the distribution of ratings as shown here.
We have implemented a scalable solution enabling the portal to process up to twelve times as many certificates in the same time period. To achieve this performance improvement the portal now uses both parallel processing and Azure Batch.
Previously residential units in Summary Certificates were displayed in the order of processing. Now where a unit name/number starts with a letter the units will be sorted by letter then number otherwise they will be sorted by number then letter.
Letter first example order: A101, A102, A103, B101…
Number first example order: 1A, 1B, 2A, 2B, 3, 4, 5…
The Chenath Repository holds background technical information on Chenath and AccuRate. It is now accessible to view from the Portal. We will continue to introduce more information and documentation when available on this site.
Adding additional white spaces to an address will no longer cause a double charge and will not prevent inclusion in Summary Certificates.
