Comments on the EECA home ventilation systems assessment

The EECA had a report done (Jan 2009) on the home ventilation systems available in New Zealand.

This report (like most reports) seems to be done from a perspective and reading other reports. Some of the writer's points of view are valid but still need discussing.

Over the next few weeks I will put my perspective across to allow open discussion on various sides of this debate and I welcome any comments on my points of view.

Have a look at http://www.easierventilation.co.nz/eeca-home-ventilation-systems-assessment.html which is where i've started, if you have any questions or specific points you would like me to cover please leave a comment below this blog or email me here .

I feel this needs to be thought through far more than it has been, imagine wrapping the houses up with double glazing and insulation and then ventilating using our old methods of opening windows, this really is not up to doing the complete task ........

Condensation in Auckland NZ

The weather we’ve had over the last few weeks has been great with cold nights, frosty mornings and fantastic days.

These conditions give us lovely fine days but also perfect conditions to produce bad condensation on windows including some double glazed window frames.

On these cold nights we heat our homes more, this in tern draws more water out of our carpets, curtains and all other porous surfaces. Heating the air enables it to hold more water vapour, this we don’t notice as we are warm and cosy – and what we don’t realise is that it costs us to keep the water as vapour. While the air is kept warm the water vapour will........
