So they match, get them to put 2 aside in the garage. Then after handover, paint the doors, fit the hardware, and put them up. Re: How do doors change energy efficiency? 15Jun 20, 2009 7:30 pm Casa2 NatB is wanting to add some doors. If indeed a reduction in air flow increased the energy efficiency of a house, which I doubt would, then NatB is only improving things. I think the inference in the software is that the doors will impede airflow and the cooling affect of crossflow ventilation, which the software assumes it needs as part of the energy efficiency. It will even assume the doors are open/closed for a % of the time. "ECOECO" At 'EcoEco', we design windows, we design the best windows, we do it for you, so that when you’re happy we are happy.

Adding the doors increases thermal comfort through more configuration options.

I dont know how much difference it will make, but I will be putting a split system in the theatre room and will probably only have the doors shut when I'm watching a movie or something. The rest of the time the doors will probably remain open.

He has a 5* star rating on your house AS IS. If you put the doors the theatre would need to be modelled as a new room, whereas it is currently modelled as part of one big room (whatever it connects to). Casa2 etc are right, it will probably make no difference to the rating or slightly improve it, BUT if audited your builder's 5* rating will be wrong becuase the house has been changed. I would do what was suggested above, get the architrave etc fitted and then do the doors yourself later, or otherwise you have to pay the extra $300 to get the thing rated again. Re: How do doors change energy efficiency? 20Jun 22, 2009 12:40 pm Hmm I see... The theatre room already has one door included, I just want to change it to double doors. I'm not even sure why I want double doors, I just do!! For looks I think! I just don't understand how adding one extra door can make so much diffrence? I guess if it does change the energy rating I'll just get them to do the door frame and I'll install the doors after handover, as suggested Building 'The Kingston' (with 'Boston' elevation) through Blueprint Homes in Hocking, Perth **PCI complete 06.02.10** My Thread - https://forum.homeone.com.au/viewtopic.php?f=31&t=17607 go upvc window frames ensure insulation under colorbond. not just sarking, lighter color roof also not sure if you have seen this viewtopic.php?t=5823 last couple of pages… 4 110525 Hi, you've probably already resolved this, however, Commbank will probably pay the funds to you after you send evidence the work is done regardless the change in the quotes. 1 35305 5 10459 |
