Building with Structural Insulated Panels (SIPS) means you can wave goodbye to conventional heating systems and dramatically decrease your homes energy waste.
SIPS are highly insulated, and exceptionally airtight. In return, have extremely low U-values, minimalizing energy loss. An airtight structure will ensure that you are retaining a comfortable temperature, but it also means that ventilation can be restricted, and could reduce the air quality.
A solution for this, would be to install a Mechanical Ventilation with Heat Recovery System (MVHR).
