I have failed to get a download button to help me download Hevacomp Mechanical Designer V8i Perpetual License. Can someone help me to overcome this?

I have placed a system marker (tank) and now the pressure is not sufficient. If I have to change it to a pressurized system, How do I do it?

Afternoon all I hope someone can shed some light on what i think is a problem with hevacomp connect, i am currently working on a large project and at the transformer, we have a fault current of 24kA but 10m upstream we have a fault current of 7.9kA…

I have been using other building modelling software that make use of the standard NCM Construction Databases for library / inference. Are there any plans for the NCM Construction Databases to be added to the Hevacomp Materials & Glazing Database?

I'm new to Hevacomp and looking to find out: 1. Is the Heat Loss and CIBSE Gain elements of Hevacomp v8i validated in accordance with CIBSE TM33? 2. Is there a list of the standards that CIBSE is validated against? Thanks in advance.

We have an unusual project (for our company). Our client wish to use a large warehouse space and create rooms within the space up to around 4 meters high. 4 Pipe fan coils units will then be installed at this height to force air down into each space …

Good morning. This may be a function i am missing but is there a way to split pipe sections? I am creating a header pipe in Netsys Gas and the last part of the header always takes on the properties of the last connection. For example in the schematic…

We have been asked to model a partially conditioned space to see what percentage of the year the cooling will be insufficient to maintain a reasonable temperature. Is there any way to do this with any of the summer time simulations or frequency simulation…

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

Hello, I have a building which has a zone with local split AC unit providing the main heating and cooling with a centralised ducted air handling unit which provides tempered fresh air. The air handling unit has heat recovery and the capacity to heat…

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?

Although I am a registered Energy Assessor I only produce EPCs infrequently in Hevacomp. I now need to produce an EPC for a project and realise I need to update my training to 2013 Regulations. I can see that free update training was available in the…

Hi, What is the best way to add openings to external walls in hevacomp? There doesn't appear to be a native feature and I haven't had much luck using custom windows/doors Thanks!

Good Afternoon All, Using Hevacomp design database (and CAD input) I have built a large 4 storey 'complex' building from the 1700's containing around 200 rooms, to get some idea of heat losses throughout the building. However, now the model has been…

Hello, Can anyone assist with the silent installation of Hevacomp v81 26.0. I have found forum posts for Microstation, but not Hevacomp: http://communities.bentley.com/products/microstation/w/microstation__wiki/4170 I need to create a silent…

When trying to add a pipe header into a Netsys project, firstly I can't seem to edit the length/size only the rotation and secondly once the header has been positioned and supposedly connected to the emitters and a system marker, it comes up with an error…

So I am using Bentley Hevacomp to create EPC's and then lodge them on the CIBSE lodgement portal. However, the Hevacomp on my PC is not producing a .xml file so I am having to jump onto my colleague's PC and get the .xml from there. Obviously this is…

Hi, Please would someone be able to help me. I have been trying to complete an SBEM for a client and this one part of the BRUKL document won't show up when I run the compliance section of the Part L in Hevacomp. On the roof of the building in question…

Hello, I would like to ask a question about the setting floor for each room. Could you please let me know how create individually the thickness of a floor for each room. Conditions folowing as; 1. no using a file of roof.dxf 2. possible or impossible…

Hi, this is Yu Koyama have taken Hevacomp training in Manchester last year and have a question. My designing building does not have the false ceiling. How can I set that "False Ceiling Height" is 0(zero)m in CAD input defaults data?

I am trying to model a room in which part of the external wall is below ground level and the remaining part is above ground level. Anyone know how to do this please?

HI, I am working on a project which is an office refurbishment and I need to introduce the fixed chiller maximum capacity to 2 kW. I found that this can be done in Simulator - Plant Data - Chillers but no matter how I alter the chiller output, the…

Hello, I am trying to model an Indirect Water Cylinder within 'plant data' for a Level 5 EPC. One of the variables that the software asks for is 'heat losses from unit' with the units being W/degree C. Within SBEM, the heat loss is stated…
