Plant room layout / utilities / ducts etc

[JackOrion]

We are just going over plant room layout as trenches are being starting to be dug for services.

 

Architects gave us initial layout for plant room which is in the centre of the house (2 bed bungalow, with small brick outbuilding which will be used for workspace).

 

Simplified sketch is below with kit sizes to scale. Red arrows show ins and outs. Unsure how realistic this looks! Obviously keen to get it right before pipework is laid and any concrete poured.

 

As ever any comments more than welcome.

 

– We are building to passive principles so assuming all these should be coming up through the slab?

 

– Should everything come in using ducts? (other than the 125mm pre-insulated pipe?)

 

– Should these ducts be sealed / grommeted / something else?

 

– How best to choose position of incoming / outgoing ducts?

All new to us.. architects gave a general idea but not much else. Groundworks team are great but not experienced with passive side of things.

 

Many thanks in advance 🙂
