Is ventilation a necessity or simply an added comfort to an energy efficient home?
Controlled home ventilation
So you have now decided to build your energy efficient house using ICF or PIF or Styrostones. You are going to great pains to ensure you build it air tight to ensure maximum efficiency. You are aware that it is good to ventilate the bathrooms and W.C.'s to eliminate odour and steam but why do we need to ventilate the rest of the house?
Comfort and health
Carbon dioxide (CO2), dust mites, mould spores, pet dander, smoke, Volatile Organic Chemicals (VOCs) and other airborne pollutants are forced to stay inside the home. Excess humidity increases the potential growth of mould and the possibility of structural damage to wood framing
If someone in your house has headaches, chronic fatigue, poor concentration, respiratory conditions, such as chronic colds and flu viruses, aggravated allergies, asthma or bronchitis getting the proper amount of ventilation is even more important.
Heat Recovery saves all your energy
The MVHR system will extract all stale moist air from a property and replace it with clean dry air. The exhaust air is passed through a heat exchanger to pre heat fresh air being brought in from outside the building.
The ducting for the MVHR system can be fitted and easily concealed within the concrete core of the styrostones. It is also worth considering fitting a whole house vacuum system into the property as this can be carried out in conjunction with fitting the MVHR ducts
