HVAC - Allow for the input of design Notes
In the "Room Project Schedule" add a box which would allow for the addition of design notes. This would allow for the designer to document why certain values where chosen. When the loads are printed the notes would also be displayed for reference.

Dialog Boxes to View and Edit Load Calculation Settings for Entire Building at Once
Currently to view the ventilation and load schedules the report is run and appears in an html file. If for instance the outside air % is too high I then have to exit the report go back into the rooms with the high percentage and manually overventilate.
It would be great if there was a screen that combined all of the room information, areas, CFMs, etc. (similar to the load report) but this screen allowed you to manually modify the CFMs, system static pressure, outside air percentage, etc. and by doing this all of the room information is updated at…

please show velocity and PD/100ft
by showing velocity and PD/100ft on a check layer, engineers could check work and easily scan and review a job for errors.

Add an option to the "Duct: Edit Multiple" dialog that allows users to choose whether to preserve duct endpoint connections or not.
So if I query and individual duct section and change the elevation of either end, the ducts the ends are connected to also change elevation to preserve the connection between the endpoints. If I "edit multiple" on several duct sections and change the endpoint elevations, the other duct sections connected at those points do not change elevation to preserve the connection. Sometimes, changing the elevation of one endpoint without keeping any other endpoints attached is what I want, and sometimes I wish the connections were all preserved. I think there should be a drop-down, a radio button, or something on…

Provide Weight or Area of Ducts in Takeoffs
Weight of ducts in HVAC Takeoffs provide a very simple way to estimate cost of projects.
Or, add an option to calculate square feet of sheet metal ductwork.

Make Grips Work With Diffuser Callouts
Fix the diffuser callouts so they can be moved more consistently and reliable with grips instead of using the "Move Callout" command.

Allow diffuser tags to be moved and modified with standard AutoCAD editing commands.
It would be helpful to not have to use the "special" DM commands to manipulate the diffuser tags.

Use correct fittings
The pressure drop calcs indicate the wrong fitting types in some cases. For example, a fitting that begins with "SD" stands for "Supply/Diameter" and "SR" stands for "Supply/Rectangular", etc. If you have a duct system that is all rectangular, there should not be any SD fittings indicated. Likewise for round systems, there should not be any SR fittings indicated.

Modify design load calculations and output to accommodate VAV system selection
Modify design load calculations to more accurately size/select VAV boxes. The revised calculations would take into account the heat required to overcome the additional air supplied to the VAV box that is over and above the minimum required in the heating calculations. This will help since the additional air is typically at 55 degrees and will actually add heat load to the space in addition to that required by the envelope and minimum supply air. In some cases this can be a significant load.

Create training material for the HVAC section.
The tutorial doesn't get into enough depth or cover everything, specifically the master schedule and project schedules and how they affect the project.

Choose Fittings Used In Pressure Drop Calculations
Add the ability to choose the specific fitting type used when calculating pressure drop in duct systems. Currently, the fitting type is fixed.

Variable Pressure Drop for Diffusers
Using the maximum scheduled pressure drop for every scenario over inflates the pressure calcs. This is very important for low-pressure systems with low static terminal units such as ducted VRF and Fan Coil Units that max out at .25". Using the maximum scheduled pressure drop of say, .1" for air devices make it difficult to design low static systems accurately.
