Passive houses timber frame

[Nemises]

Hi guys Ive been offered an opportunity to wire 12 timber frame passive houses, is there anything I should be doing differently as there passive?

Thanks

 

[telectrix]

don't shout at them.

What's a passive house?

 

[telectrix]

think it's something to do with low energy

 

[Nemises]

Something to do with how energy efficient they are

 

[mhar]

Ask the architect, only he will know

Thanks Tel and Nemises

That'll be kingspan everywhere then

Not going to ask the obvious, oh go on then Kingspan? Remember before you answer I'm old school therefore unfamiliar with some of the modern building methods.

also known as celotex ( different trade name). i call it PITA.

that or foil insulation snappled everywhere
makes run more of a head ache and de-rating cables etc

How odd! I've been working I one we wired a few years back only today.
Where cables passed through to the outside of the building we had to seal around them using special seal things to keep the house air tight. The house was built using natural insulation, no awful fibreglass or kingspan. The idea of a passive house is that it should consume very little energy, heavily insulated and airtight to prevent draughts, with an automatically controlled ventilation system, triple glazed windows etc. The sun, cooking and the warmth of the occupants should be enough to keep the building warm without the need for central heating. The extra insulation also makes the house very quiet.

There was masses of insulation, several feet thick in the walls and roof etc. but it was great for us as the insulation was behind sheets of sterling board then there was an un-insulated void between that board and the plasterboard to run the cables in. The plasterboard ceiling was suspended and again the void was un-insulated. Super for installing the LED down lights, which was good as there was 149 of them throughout. Almost no cables were installed in contact with insulation.

There was a bit of extra wiring for the whole house ventilation but nothing special. The building is quite big so we stuck an addressable fire alarm in. I'd love to live in such a property, the annual gas consumption for this 5 bedroom properties heating is less than £40 a year.

All timber frame new builds I've encountered are a ball ache and I've done about 10 different types!
Most where for private builders who like to keep changing the spec but that's another story!

 

[Leesparkykent]

If there is any accessories that are to be mounted to the external fabric of the building then you need a specification of how they expect you to get the cable to outside.

 

[Ian1981]

Conduit usually with both ends sealed

An airtight house sounds pretty grim to me, always have windows open a little.

 

[freddo]

The ventilation system takes care of the air quality. The windows remain closed almost all the time.

 

[Dave OCD]

I couldn't leave windows shut on a hot summer day, just not right.

 

[telectrix]

we're just starting to shut the bedroom windows at night. i'm currently sitting here 3 ft. from the open back door. think i may need to put my t shirt back on soon.

At the uni a where I work we have one of the largest passive houses built in Europe. It's called the centre for medicine building.

Iv been down in the plant room numerous times and worked closely with the sparks who spends most of his time with bms systems.

Basically to sum it up this building is aiming for an A+ rated building and that's very very rare to achieve.

Every office/room within the building has independently controlled heating and ventilation so for example if all the heating to the building was shut down it would only drop by 1 degree a day.

Any new fixing or hole in the wall has to be sealed completely etc.

It's get really technical when there are so many control systems for ventilation, heat management, air handling units etc

Yep. True

My lad lived in one these houses, well flat. The flipping air circulation fan made a right racket. I always opened the bedroom window at night, when we stayed over. All electric two bed flat, just him. £120 a month leccy bill. Not very efficient.

OP be careful where you drill holes, get it in writing!

but how much did he make on the sale of the weed?

They would never take, 'cos I kept opening the windows.

One you shouldn't shout at according to Tel.

That wouldn't of been a passive house if his electric bills are that high...It would of been a flat with mechanical ventilation.

MVHR.

 

[telectrix]

Intake of what?

i only intake 4 things.... food, coffee,beer, tobacco smoke, not necessarily in that order

Dunno, but it was sold as a most energy efficient new build, but I just felt inclined to open the windows at night?
