i Shane and Duncan, I have this error when I deleted a room in the program, it continued with this message tried all I can to try and fix but could someone lend a hand on this one? at my company we Use Bentley frequently for quick calculations,…

Hi there, I was making a building through Design Database, and I was trying to modify the name of a room. Something happened, I suspect that the file got corrupted. I can not open it anymore. Can I get some assistance on this, please?

Running Hevacomp, Design Database for Heat losses. (V8 SS1 SPB (V*i SS1 CP3 (06/16)) I want to apply a flat ceilling to some rooms since they are 3.6m high but have a ceilling at 2.7m. The problem is when I click the "Flat ceilling under this…

After having loaded Hevacomp with Admin privileges - Selecting Design Database - After Selecting a folder the project explorer, shown above, minimizes as expected but nothing else happens. The following page doesn't load, I don't receive an…

Hi, How would i be able to add 'Engineer' and 'Checked by' details on the TM52 reports under print. I have already fill the details below but don't seem to show up on the report: Many Thanks

Hi, I keep having this issue with one of my models. It is not letting me go into weather data to input my weather files correctly. My global changes and fabric data work fine, it just seems to be the weather data that gives the error message as shown…

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…

What takes precedence for people gains - is it the Standard room input data, or the definition of activity types? VS. The activity types are referenced below are from this thread: https://communities.bentley.com/products/building/performance/w/building_performance__wiki…

Tried the other fix in this forum downloading the MatIndex.zip file and extracting in to the C drive and still have the issue. Fabric details are appearing OK also.

We have a project where our client is looking to provide a new air supported structure/ dome over an existing training pitch, the structure is to be heated and cooled as required. Can this be modelled using Hevacomp.

Hi Good morning, For the HEVACOMP Heat Loss Calculation, is there a way to know the required supply air flow based on the calculated total heat loss from the result? I'm looking at something similar with the CIBSE gain calculation where the result…

I have turned off infiltration, ventilation, occupants and casual gains from my model to test the solar load portion only. However I still see loads attributed with "Convective" and "Latent" (albeit small). Should these loads exist in my calculation…

Suddenly get this message after using full CAD Input on this project for a few days. The Hevacom Project Explorer confirms my project details comprising existing data of 37 rooms but can not open the project. I can see the data on the network server directory…

I have constructed my hevacomp model in the design database using the load calculation tab along with sizing all my mechanical pipe and duct systems using the pipe and duct sizer netsys tab. I am wondering if it is possible to transfer all this data…

I received a new building outline for a building I've already modelled. I replaced the outline on a constant known point so i could make changes, saved and opened the model in hevacomp. The outline is no longer inline with model for some unknown reason…

I am having difficulties auto defining rooms the design database. After following the tutorial video, I have set up the layers on the dxf as walls, partitions, doors and glazing as instructed. The layers are highlighted as you would expect them to be…

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 understand that you get different heat gains in the following scenarios: Within CIBSE gain tool allow temperature to rise by 1degC Within room data increase summer design temp by 1degC There is a calculation procedure for the first scenario…

I modelled a simple 5mx5m glass box with no heat transfer across the floor or ceiling and I created a custom glass to replicate a Pilkington glass (U-Value of 0.6 and g-factor of 0.55). When I checked the solar gains using CIBSE Gains they were 10.8kW…

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…
