My model consists of two floors, 2.7m high for first floor and 2.7m for second floor. I added a pitch roof which messed the whole model up, so i deleted the roof data from the DDBROOF.NDX folder along with the ROOFPOLY.* and RLIGHTPOLY.* files. The model…

Is there a guide for the electrical design software? I am new to Hevacomp and have only used amtech before. Also I have noticed that the application window says 17th edition but there is an option for the 18th edition too?

Is Hevacomp integrated with projectwise? Is their a routemap to using Hevacomp with projectwise at all?

Hi Shane i wonder if you would kindly take a look at a project file which may be in need of repair. This has happened before and I uploaded the project folder and you where able to repair the file path to the project. The project was loading fine…

Hi, Please can anyone tell me the best way to derate XLPE cables to run to a maximum of 70 degrees instead of 90? Thanks

Hi, regarding Connect, under Supply type Special what value is expected for Fault Current? Is it phase to neutral for single phase and three phase supplies or for a three phase supply do we input the fault current between phases?

Can anyone tell me if there is a quick way to eliminate negative heat losses from a calculation run without having to go through and manually exclude those rooms? I would rather that these spaces display as zero heat loss rather than a nett heat gain…

We have a modelled system in Hevacomp which has a cooling load of 16,065 kW and a delta T of 8.4 deg C. Hevacomp calculates the volume flow rate to be 421 l/s. How does Hevacomp calculate this and what value does it use for the specific heat capacity…

Hi On Hevacomp Netsys I am trying to get pipe properties out. With flow rates some values are coming out as 0.000 and it seems like the minimum value it will show up is 0.010? Is there a way to change this so that it doesn't round up/ not show values…

Hi All, I am carrying out a frequency simulation calculation and want to add in an amount of fresh air to see the effect this has on overheating - either via air change rate or fresh air for occupants. I know that the methodology for this is either…

Table 41.3 of BS 7671 stipulates the maximum Zs for circuits. Having printed off the impedance results for a project a number of circuits are in excess of the maximum permitted zs from table 41.3 How does Connect carry out a calculation, and then…

Where can I access the operation manual for connect?
