Mechanical ventilation with heat recovery (MVHR System)
An Ecologic SIP build system provides a vast improvement on air tightness as compared with more traditional construction methods, therefore careful attention needs to be considered to the ventilation method to create and maintain a healthy living environment. The average family of four produces up to 18 litres of water vapour everyday through normal activities such as bathing, cooking, and even breathing
Healthy buildings usually require a full change of air every two hours (m³/m²hr), as indoor air can be up to ten times more polluted than outside air. Mechanical ventilation with heat recovery (MVHR) offers the best solution to providing adequate ventilation for a SIP house. MVHR Systems are designed to quietly operate 24 hours a day, continuously circulating fresh air through the structure while removing unwanted moisture and pollutants.
MVHR systems, in combination with the excellent insulating properties of a SIP structure, greatly improve the energy efficiency and ultimately reduce your carbon footprint.
