Individual split-system cooling simulation for apartment buildings

We are modelling an 18-storey tower (containing about 100 apartments) in China using 'detailed HVAC'. Heating comes from a coal-powered district heating system and cooling is provided by small individual refrigerant-driven split systems (mostly 2.5kw Mitsubishi AC units). Am I right in thinking that...

Creating a concave roof geometry

Hi all I am just wondering if anybody has any suggestions on how to create a concave, tent-like roof geometry which I need to create of an existing building (photos attached). I am using the dome command to then cut 3 half domes to replicate the three concave type patterns that shape the roof, but t...

Creating time-variant zone target temperatures

Hello all I would like to calculate heating loads for a horticultural greenhouse to achieve real space temperatures that are defined for each hour (therefore I have 24 target temperatures over an operational winter day). I know this could be achieved using 1-7/12 schedules to create variable tempera...

Modelling of incomplete external insulation

I aim to model a 1950s multi-storey apartment block where internal wall insulation was added to perimeter walls. Therefore the intermittent concrete floors (which completely penetrate the external fabric) are uninsulated and form repeating cold bridges. Any tips on how best to represent this in desi...

Floor area error

Hi Everybody While simulating a large building, I get the following message: King's Gate - Total zone floor area - excluded floor area must be > 0 - 3rd Floor - West Atrium West atrium is a void that continues all the way up the west side of this building, and to simulate it I have drawn holes cover...
