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: Part L Glazing
Hi Andrew,
Yes, you just need to enter the manufacturer's figures into the Glazing Properties section, in the top right of the Glazing Data menu. Please see further information here .
We would also recommend obtaining Solar Gain Factors from the manufacturer…
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…
Incorporating more than one wall type in a section of external wall using DDB
On typical single storey warehouse buildings where blockwork cavity walls are often used for the lower section of external wall, and either single-skin or double-skin metal sheeting is used above the blockwork walls up to the roof line, how can this be…
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?

RE: Two internal ceilings when I add a roof.
Hi Tony,
You need to use the Setup Exposed Roofs command to connect your roof surfaces to the rooms below. This article may be of assistance.
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.

Should any other users require further guidance on roof design then please see this article .
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.
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: Glazing database - effect of adding blind on G value and Shading co-efficient - CIBSE Gain
Hi Michael,
It is my understanding that the Uvalue and light Transmittance figures will not be affected by the blind, while the Shading Coefficient and SHGC would definitely be impacted. However the glazing manufacturer will need to confirm this for…
