Floor/Ceilings and Thermal Mass

[langywangy]

Hi,

I am currently doing an exercise using thermal mass and seem to have strange results where the intermediate floors are concerned. When looking at the construction manager I note that exposing the floor surface does not increase the thermal capacity of the floor/ceiling element. Am I right in thinking intermediate floors are only ever considered as ceilings where thermal mass is concerned?

I am a doctoral research student looking at thermal mass effects on energy use and it is a given that exposing a heavyweight floor will have an impact on its thermal characteristics. Therefore, I am unsure why you wouldn't be able to alter this. I'm sure it's just my inexperience with the programme.

Thanks

Please refer to the SBEM documentation for more details on how the thermal mass is calculated for each construction.

The category (lightweight, very lightweight etc..) is based on the SBEM Cm value.
