Re: Completely air tight homes? 19Apr 30, 2010 12:01 am Thanks for suggestions. Will check them out. Anyone could point me to pictures, description etc of the actual "Trickle ventilation..." Also, trying to understand... the "Very easy to fit into the rebate" and "it is hardly visible."

Not sure I understand how these units get installed. Could not find any examples of size of the ducts and how ducts are done to ensure air is changed in all rooms slowly but surely. If the ducts are too "invasive" to a 2 storey home structure feasibility of installing the whole system would be very low through a variation with a package home builder. Has anyone ever tried successfully or not installing such ventilation system through a variation with a package home builder? What would be an indicative cost of installing a unit like "air-change" or "Venmar Air Exchange System" in a retail situation for a 300m2 double storey house? Through one of these links led to very interesting information - http://oee.nrcan.gc.ca/Publications/infosource/Pub/hrv/ventilation.cfm?attr=4#conventional. The following statements would be very true for anywhere - this material is Canadian: - "In recent years, more and more existing homes have undergone energy-efficiency improvements such as upgraded insulation, improved air sealing, the installation of energy-efficient windows, doors and heating systems, etc. As well, improved practices in new home construction have resulted in more energy-efficient and airtight conventional homes. In many of these homes, air infiltration through doors, windows and other openings in the building shell is too random and does not always provide adequate ventilation, which is just as important in a conventional home as in an R-2000 home. Even when there is an acceptable rate of air exchange, the fresh air may not be getting to the rooms where it is needed. As a result, mechanical ventilation is needed in many conventional homes in order to evenly distribute fresh air throughout the home and maintain a healthy living environment. An added benefit of mechanical ventilation systems is their capability to filter the incoming fresh outdoor air." - "Based on these figures, a ten-room home (unfinished basement, living room, dining room, family room, kitchen, two bathrooms, a master bedroom, and two bedrooms) would require 60 L/s of fresh air" (minor adoption/edits) - "the standards used in Canada, a minimum ventilation rate of 7.5 L/s (15 cfm) is required for each person in the home in order to provide a level of indoor air quality that most people would find acceptable." After browsing these links, one wonders if it just seems other countries are leading years ahead or it is actually happening......

And is it possible to disconnect the duct joined to the vent from inside the house, without going into the roof cavity? 0 5996 Hi all, sorting out the ducted air con for a 350sqm double story house.
