I am trying to get my head round ventilation
and what would be best to install in a highly insulated masonry eco home - ventilation that doesn't just evacuate the warm air. . There's passive whole house, mechanical with heat recovery (MVHR) and even a type that extra heat can be added to the incoming air. There's also a new gizmo on the market now called dwell-vent windows, where air enters the house via the gap between the inner and outer pane of a window and is said to warm up in the process. But how does that
impact on the whole ventilation. Will bathroom air still evacuate.? As if it wasn't complicated enough I have this past week come across bespoke systems whereby air is drawn through an underground pipe into the house, claiming to warm it up in winter and cool it down in summer. REHAU also do a ground to air system called Awardukt. This sounds a clever idea but I've not read anything from users about how this impacts on the whole house ventilation.

Has anyone any useful tips to pass on about ventilation and these different perhaps complementary products?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=332&Focus=3592#Comment_3592 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=332&Focus=3592#Comment_3592 Fri, 01 Jun 2007 09:15:23 +0100 nigel https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=332&Focus=3595#Comment_3595 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=332&Focus=3595#Comment_3595 Fri, 01 Jun 2007 09:55:29 +0100 patrick
For cooling the best results were always; shading the windows or venting to the outside air (which in an occupied insulated house was often cooler).

I found this all very disappointing as I had always felt that ground effect cooling was such an elegant solution.]]>
