Open the application using the shortcut in the Tas\Utilities folder. The folder is in the Tas Manager on the left.
For a Part L 2010 analysis you should use the 2010 studio in the same folder as the 2013 studio.
The version of the NCM internal conditions database that you should use for Part L 2010 projects is _v4.1.4. If you're working on a Part L 2013 project then you should use _v5.2.1.
If you've started a Part L analysis in the 2010 studio but you want to use the 2013 regulations going forward then you will have used internal gains as per _v4.1.4 of the NCM database. These will need to be updated to _v5.2.1. When you open your 2010 TPLP in the 2013 studio the application will automatically update your internal conditions using the _v5.2.1 database.
Exercise and Notes
Assuming you already have source T3D and TBD files that were created in Tas v9.3.0, open the Tas Manager and then double-click on the UK Building Regulations 2013 Studio in the Tas\Utilities folder.
The source files used in this tutorial are for a fictional building with HVAC groups for natural ventilation, fancoil, mixed mode, and extract only. HVAC zone groups were created in the source TBD. The relevant zones were then added to each group.
The building data file has already been set up with internal gains from the NCM database v5.2.1, and natural ventilation and mixed mode aperture types have already been added. For mixed mode apertures the cut-off temperature has been set to 25 degrees C. The window will be fully closed at 26 degrees C. When the air-side system is set to Mixed Mode in the studio the actual building will be cooled to 27 degrees C.
A surface output specification has already been applied to the relevant PV and SHW surfaces to model renewable energy sources. In Tas v9.3.0 and later versions the surfaces aren't needed so you will be able to model solar thermal and photovoltaics without having to draw them in the 3D Modeller.
