RE: Connect - poorly aligned text on plots
Hi Andreas,
I can confirm that the original issue was resolved in Hevacomp v26 , however there is a slight misalignment of Board names in some instances.
This only applies to PDF's, so a workaround is to export to DXF (File>Export DXF), in which all…

RE: Modelling a zone (room) within a zone (room)
Hi Stuart,
Modelling of such spaces can only be directly achieved in Hevacomp Simulator by using Atrium key words. However if you wish to use Design Database for level 3/4 Part L calcs then there are three workaround options available - please see further…
RE: Hevacomp upgrade problem
Hi Martin, please find steps showing how to resolve this matter here.
RE: Plant Schedule
Hello Matt,
Can you clarify which software you wish to do this in? Are you talking about Design Database - PartL or Dynamic Simulation?
Regards Steve
RE: HVAC Systems - Zones
Hi Matt,
I would firstly advise caution if you are intending to use Part L to determine if natural ventilation is required, as SBEM is not a design tool indicative of real-world conditions. (To see if natural ventilation is required you would need to…
HEVAcomp export options (into AECOsim)
What are the options for getting HEVAcomp models into (3D) Microstation or AECOsim?
RE: Yearly Gas Useage
While these results are not directly available in the software, the Energy calculation in Design Database may be helpful as it will provide the annual energy usage in GJ. You could then use these figures to work out your gas consumption.

RE: Variable Flow systems in Netsys
Hi Nicholas,
It is not possible to directly specify variable flow at outlets, however diversity of pipework systems is now taken into account in accordance with BS EN 806-3. Please find further details about the calculation method here.
Variable Flow systems in Netsys
It's been some years since I used Hevacomp and am now considering purchasing for my mechanical team. Can someone explain to me if it is now possible to consider diversity and variable flow in the piped and ducted systems?
If for example, we consider…
RE: wall heights
Hi,
Please use the 'Setup intermediate floors/ceilings' function (located in CAD Input > Roof/floors ) to set up the adjacencies between these floors. This will remove all gaps between your floors.
RE: Window glazing properties, CIBSE Gain
Hi Kenny,
The different standards used by each Hevacomp calculation prescribe their own equations, each requiring their own particular variables. In the case of the CIBSE Gain calc the most important variables are the Solar Gain Factors. SHGC is not…

RE: How to include Hot water cylinder in Netsys (CWS)
Hi Jozef,
The guidance here should assist with modelling this.
How to include Hot water cylinder in Netsys (CWS)
I'm designing the CWS. The Hot water installation requires a Cylinder.
How can include a cylinder in the CWS design? I just can find the option to include a Cold water tank in the system.
Thanks
