Posted By: Peter AAndy,Have seen in last few months reference to a Givlon screed that can be used on upper floors of timber frame flats, would this be of any use. I would be concerned over a block central core with all the settlement issues associated with timber frame. With correct design you should be able to overcome over heat issues, ie orientation, solar shading, glazing spec and some sort of solar chimney.
Posted By: biffvernonIn days of old many timber framed buildings had lime-ash floors. That was all long before steel beams, concrete and structural engineers were invented, but it provided high thermal mass with little embodied energy.
Posted By: biffvernonIf you want to incorporate thermal mass in a green building the first material of choice has to be earth.
Posted By: andy(Gyvlon screed) quite tricky as a service void would be required below the ceiling to minimise disruption (and mess!) of future services installations. This would create an insulating layer detracting from the thermal mass.
Posted By: LizMThe first floor itself could overheat without thermal mass in the roof.

Posted By: GuestThe building project I was involved in was passivehaus standard, zero waste, earthquake proof, recyclable, reusable, fireproof, non-toxic, very low embodied energy and can be mass produced to any design. The icing on the cake is it easily meets code level 6 ' code for sustainable homes'. Plus dealing effectively with water conservation issues, which I feel the 'code for sustainable homes' doesn't address properly.
Posted By: andy...mass using earth or similar within the floor...exposing the surface as a ceiling finish would mean the ceiling material would be holding a loose material...I would not want the local maintenance company drilling holes and emptying bays of material as has happened within many older buildings of similar construction.

Posted By: GuestPeter ASorry for my ignorance about the electrical generation requirement on Code 6. But does the excellent water management capabilities of the system not offset this somewhat? The structure can be super insulated to passive house and the price - from what I overheard - will be substantially lower cost and much faster build than anything presently available.
