Hi
In HVAC part of ASHRAE 90.1 PRM, for baseline if we selected the one system from library from 90.1 should be set the component setting on the air network or there was set by ASHRAE information ,or we just design and edit in proposed part.
regards,

Yes, users can edit the baseline systems after they have been imported. The following is taken from the ASHRAE 90.1 App G PRM User guide.

Edit Current Baseline
Users are presented with the ten ASHRAE 90.1 baseline HVAC systems, which correspond to System 1-8(10) listed within Table G3.1.1A and Table G3.1.1B (2007 & 2010). Users must identify which baseline system is required to be modeled for the project in question based on the ‘building type’ (type and area) and whether the energy source is a combined approach (fossil fuel, electric, hybrid, etc) or ‘electric or other’, which are outlined in the tables mentioned above. Once the system type is identified users select & import the system(s) on to the ApHVAC work space. A number of system loops will need to be imported depending on the system design in question. Prototype systems can be imported in a vertical or horizontal placement. The auto placement automatically arranges HVAC systems in a tidy fashion on the work space.

Improve Upon Baseline
Users are presented with the option to use the Baseline system as the proposed system. Edits can be made to the baseline system & then saved as the proposed system. This is a useful feature for early stage PRM modelling.

Dear Terence,
Thank you so much for your useful answer with the benefit details.
