  • Calculations - Occupancy and heat gains

    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…

  • Does anyone have experience of modelling an air supported structure to ascertain the heat loss.

    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.

  • Adding NCM Construction Databases (standard library / inference) to Hevacomp Materials & Glazing Database

    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?

  • 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

  • CIBSE Gain - Temperature rise

    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…

  • RE: CIBSE Gain - Results Breakdown

    Matthew, you have probably turned on Temperature Rise in the Design Data tab. When you use Temperature Rise the individual loads are combined in the underlying equations and cannot be accurately split out afterwards.

  • RE: Uncontrolled heat gains

    Hello, Please post your second question regarding CIBSE Heat Gain to a separate thread and I will try to answer it there. With regard your question on Summer - The Summer calc uses Operative Temp as defined in CIBSE Guide A5 Section 1.2.2. This equates…

  • Why is the Hevacomp BRUKL Document not showing Solar Thermal Systems?

    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…

  • RE: Modelling variable wall construction in single element

    Hi Roy, it may depend on the type of calculation you are doing as to the best solution. The simplest option is to create an Exposed Wall in Fabric Data using the layer data for the above ground wall. Once created you can adjust the calculated U-Value…

  • RE: Walls, partitions and sections

    Chris, to extend on Duncan's answer you should consider the following. Steady State calcs such as CIBSE will consider the temp on the other side of a partition. When using CAD Input this will default to the design condition specified for the adjacent…

  • RE: Glazing data

    You can also change all, or specific glazing for the project by using the Global option on the main Design Database menu. This allows you to make changes for specific rooms\all rooms. You can also restrict changes to only change existing glazing of a…

  • RE: Hevacomp - Design Database - Special Surface Types

    Hi Rob, By any chance is this a glazed door? Any door that is more than 50% glazed is considered a Window for PartL purposes. If you set a glazed area greater than 50% then we automatically treat this as a window when we pass it to SBEM. This is…

  • RE: Hevacomp Weather File Error

    Hi Michael A quick follow up to my colleagues response above. Once you have set up the correct permissions to the software, you may need to reset your project's weather location so the project can function correctly. Load up your project. From within…
