+1 what threebedsemi has stated and I note the following.
At the moment the regulations are dancing around the idea of full air conditiong for a building.
MVHR doesn't supply cooled, moisturized, dried or heated air to the internal spaces
MVHR is the "cheap" version of aircon, because it only reclaims heat.
The heated supplied air isn't filtered to the highest standards.
The potential problem that's waiting to happen in Ireland is that our super insulated and solar-gain-oriented houses will become virtually uninhabitable as the summer months get hotter over the years.
At the same time sthey will be unable to guarantee air quality in the winter in areas where everyone burns their fossil fuels and wood pellets locally.
Air quality seem to be the big question for city dwellers especially those raising children and it affects super-sealend-and-insulated hosues too.
Just opening the windows in the summer and closing them in teh winter won't provide all the answers
====================
That having been said, air which is too dry is not good for you.
It can dry out the sinus membranes and lead to respiratory ailments.
This used to be a common complaint made by people who used to leave their central heating on all the time without properly "airing" the house.
One argument being advanced currently appears to centre on local vents in walls that are activated when the air quality drops below a certain level, whatever that means.
There is huge difference in the perception of "being cold" between old and young (in general) and between active and inactive people.
Older inactive people being the worst sufferers and young active people the least, so here is some general advice.
- Put on an extra layer of clothes if its cold.
- Ventilate the house every morning.
- Get regular exercise every day.
Lower your heating bills that way.
====================
Just remember, your overall energy usage relates directly to anything you use with a heating element in it.
Space heating is only a proportion of the energy used in a modern family home.
Cooking, making tea, washing clothes and dishes, having showers.
All these use huge amounts of energy in an average home.
