Thanks SAS, good answer.
I'm trying to get my head around how the valves work in the flue.
Obviously the valves open when the fire is on, and close when there is no fire on
Are the valves automatic, or do they need opening manually when a fire is lit, and closed manually when there is no fire. It might sound like a stupid question.
thats a fair point GTT, but lets not kid ourselves that a "passive" house is one that is not certified.
....but to truely have a passive house you must have it certifed. this certification includes a data logging timeframe afterwards to prove its credentials.
Otherwise its entitled a low energy build... which is noble in itself.
I'm afraid I disagree. You truly have a passive house when it performs like one.
The presence or absence of a cert will not affect that performance one iota.
<snip>But a certificate is proof non occupants that its DOES perform.
Without a cert, wheres the proof?
Would the heating bills not provide some form of empirical proof.
[this, from a guy who issues certs for a living]
ONQ.
PS Not passive house certs, BTW...
Noob question: How is heat escaping when people enter & exit these passive houses handled?
I'm wading in here. I'm completely with Syd on this and I'm going certified (assuming I can satisfy the criteria).
You won't have heating bills. You will have an ESB bill alright. But most passive houses (even in our milder climate) will have a stove of some sort as a back up and it's not easy to prove how much or little you light it.
Plus there are people that are very warm souls that need a window open at night in order to sleep. There are those that prefer to be able to walk around in our underwear when there's a foot of snow outside. To the former, any house could be warm enough. You see where I'm going.
My biggest fear.... I'm building a house (3256 sq ft) to PHI spec with the target to achieve the certification. However, if I fall short (say 16kw instead of the 15kw target) I don't get the cert but the house will perform like a passive house. The certification has to draw the line somewhere so I don't have an issue with this. If faith should deal us a bad hand 5 years down the line and we were forced to sell, all I really have is a big house that needs a heating system installed from a buyers perspective. I'm actually planning on burying rad pipes in the screed so that should that happen (or if we fall we short of passive) I have a fall back that doesn't involve digging up floors etc to resolve.
its not handled
when the triple glazed argon filled airtight doors are opened, heat will escape.
