EDSL Tas has the ability to import IDF files (and gbXML files, DOE2 INP files,...) for geometry, building fabric, and internal gains/schedules. Tas also has an ASHRAE 90.1 Studio which automatically generates the baseline buildings and baseline building HVAC systems with post sizing efficiency tools to automate the majority of the process.

The 90.1 Studio in Tas has the 2007, 2010, 2013, and 2016 90.1 HVAC systems. The baseline building lighting and HVAC systems creation is fully automated as well. Once created all the systems are editable if needed, however this should not be the case for the Baseline buildings systems. www.edsltas.com

Dry Air Cooler, just in case it was slightly a question.

The info to join the Unmet Hours Slack channel is here I believe:

I believe you would need to create a Slack account to view the images. To get the images otherwise please message me via LinkedIn or by email so that I can email you the example images to match the above descriptions. Best, Michael

...is already efficient.

Example 3: https://files.slack.com/files-pri/T0A... DOAS is possible in E+, though I believe this more complex airside model is easier to set-up in TAS. Again, I believe the issue is to do with the topologies that E+ can accommodate easily. I have attached a simplified example to illustrate a dedicated outside air system in TAS.

Example 2: https://files.slack.com/files-pri/T0A... The attached blended system is not so complex, but again isn't easy, maybe impossible (?), to recreate in E+. The idea is to have a single chiller produce 6C chilled water for the AHU, then have a tank as a store that is set to use the 6C chilled supply to then maintain a supply to chilled beams at an elevated temperature, in this case 14.4C. There's a cooling tower to take advantage of the higher beam return temperature, although that turns out to be less beneficial than you might think if the chiller...

TAS can model radiant heating and cooling systems as well, such as underfloor heating/cooling.

Try these, can't upload images on the website as far as I can see, if it was possible I would gladly upload the images:

Example 1: https://files.slack.com/files-pri/T0A... TAS can handle complex topologies. First I have attached an example of a rather complex waterside system, which I don't think any other package could simulate, although I stand to be corrected on that. My understanding is that this topology would be impossible to simulate in E+.

I have actually answered the same question regarding more complex airside and waterside topologies on the Slack Unmet hours channel, I don't believe I am able to upload images here. However, I have posted links to the comments on the Slack channel:

Example 1: https://unmethours.slack.com/files/mi...

Example 2: https://unmethours.slack.com/files/mi...

Example 3: https://unmethours.slack.com/files/mi...

I stand to be corrected with regards to any of these examples. Hope this helps.

Hi Annie,

Tas can certainly model DOAS systems and chilled beams. I would be glad to provide you with a demonstration and go over any questions you had regarding the software to help you get to grips with it.

We have good documentation for our Tas Systems application in the installer of Tas and very good support. Tas Systems, our HVAC and controls simulation software, is similar to the way E+ does its HVAC simulation, but we can handle more complex waterside and airside configurations. In Tas Systems you can either build out your schematics using drag and drop components (or drag and drop pre-built systems you have saved in a library) or use a system wizard to generate a good starting point for say your VRF system with natural ventilation and then modify as necessary. Tas is ASHRAE 140-1 compliant and uses its own fast proprietary simulation engine. Tas Systems calculates a new ‘heat balance’ at every hour.

Tas can also account for the thermal lag through a radiant slab.

Please let me know if you would like a Tas demonstration/trial, and we can arrange one in the coming weeks.
