There must be some dependencies on building form with emboded energy quantity.

Speaking about low energy building built in cold, heating dominated climate:

1.Simple form building always has less thermal bridges, so it could couse lover thermal energy consumption.

2. Complex geometries need more construction elements for structural support - if it is done inncorectly, that could increase ammount of emboded energy.

For beeing more specific - optimum ponint may be different in different climate, with different heat sources and finaly if transportation is taken in to account - geographic location.

Really appreciate your answer, Karolis.

My research it self actually focusing about building form and massing of public housing, and its influence to outdoor thermal comfort.

I'm still trying to connect between the geometrical aspect that influence to embodied energy and I assume will give impact to surface temperature as well.

Yes, somehow climate as heat sources especially in a hot humid tropical zone is giving significant impact .

looking forward with other discussion

In hot climate thermal amount of available thermal mass could influience cooling needs, because with massive building, there are posibilities to utilize passive cooling by night time cooling. Building form (or more internal layout) influences posibilities to use natural ventilation based cooling techniques.

Beta - are your aim for ideal solution from emboded energy consumption and comfort point of view is to characterize building which "does not heat up" (has low cooling load and demand) or building form which could be effectively cooled (low total cooling energy consumption)?

I suggest to try some energy modeling programs like EnergyPlus (interfaces are OpenStudio, DesignBuilder Simergy etc.) and try to simulate few different forms. By using corelation analysis try to find dependencies on area to volume (or thermal mass) ratio for time when thermal comfort criteria are not met.

Take a look at this persons work (mostly PhD thesis) if you found last part interesting : http://www.mendeley.com/profiles/ivan-korolija/

My research not specific in energy consumption actually, but somehow would be connected.

I made some flats assessment through ENVI-met simulation, and i found volume ratio also giving significant impact to outdoor thermal comfort.

I've heard about Energy Plus and haven't use this program before, but as far as i know, this is used know HVAC especially for indoor. i'm afraid this is not suitable for my aim to find outdoor thermal comfort. Therefore, I prefer to use as a reference. Great link, indeed will give a lot of information for me.

The surface area to volume ratio (SA/V) or more precisely the form factor (SA/TFA) ratio of a building will strongly influence the payback time of any embodied energy in a building. There is a strong correlation between compact building forms and space heating and cooling energy requirements. Thus the economics will tend to favour more compact energy efficient forms, lower embodied carbon materials, and higher U-values. The optimum trade off between these factors will always be climate and building use specific however.
