That way no uncontrolled air can enter the house from outside it can only be pumped out via the rangehood. The only reason I say this is because recirculating rangehoods as has been noted really aren't the ideal option. possibly. I could look into that option. Do you know of any I can look up specs etc? any brands you know of? Re: Non Vented Rangehood Advice 8Jan 22, 2015 5:19 pm ktotherose [. possibly. I could look into that option.

I think you are overthinking this a little. Go to some appliance shops and have a look at whats available.

(http://www.nytimes.com/2010/04/01/garde ... .html?_r=0). I work at an energy efficiency laboratory in the US where the scientists call them "forehead greasers." The Passivhaus standard does not call for the house to not exhaust dirty or damp air, but rather that needed makeup air only be allowed in when exhaust fans are operating, and ideally be 'pre-conditioned' (heated or cooled as appropriate). In really efficient systems the makeup air is arranged to exchange heat with the air being exhausted. In the US (where climate extremes are often much greater than in Australia) there's a new industry in powered makeup air units that solve this problem. I'm not sure if air-exchange appliances are available in Australia yet, but if not you can always crack a window. Its better than breathing in cooking vapors. Chris On the threshold of retirement... and trying to check my assumptions at the door Re: Non Vented Rangehood Advice 10Jan 25, 2015 7:53 am Another question, do you have any other exhaust fans in toilets, showers etc? If so how are they treated under the Passivhaus guidelines? I would not have a recirculated system. You can eliminate all the smell even with charcoal because it becomes less effective as it gets dirty...expensive option cheaper to duct externally. Re: Non Vented Rangehood Advice 11Jan 27, 2015 8:11 am Thanks, I think we have it all sorted. Will still have to go ahead with a no vented rangehood, however our heat recovery unit (controlled air exchange) will shift the air to the outside. We will have a vent close to the kitchen and just have to make sure it is on when cooking. Re: Non Vented Rangehood Advice 12May 03, 2018 4:13 pm How are you going 3 years on? We're in the same situation - going with a tightly sealed home using a zehnder HRV. Venting outside is a big problem with tightly balanced HRV homes. Make-up air options are possible but they're far from ideal and bring their own problems. Our architects have been using the Qasair Rangecraft units that have a "plasma" chamber that seems to vaporise the vented air from the rangehood before running it through carbon filters and the re-circulating. They're quite expensive however so I'd love to know if anyone else has seen/used them as the documentation is quite light.
