HVAC Sizing

Since SIPs are so energy efficient, the correct sizing of your HVAC is a crucial step in the building process. Sizing requirements used in traditional construction must be modified to meet the superior standards of SIPs. This often means the size of your HVAC operating system can be substantially reduced, ultimately saving you money. The incorporation of an air to air exchange is required for all SIP structures. Whether you choose your own HVAC installer, or you work with ours, we will assist in determining the correct HVAC system for the energy efficient structure.


What Our Customers Have To Say

Our two dimensional dream house was finally going to become a reality. Extreme Structures converted our sketches to blue prints and engineered a safe way to build it. Team Extreme gave us the courage to become general contractors and build our own house. Installing windows and doors was a snap because of the squared framing and dimensional accuracy. Inspectors and tradesmen were awed and appreciative of the little things done by Extreme Structures that made their job easier. Now a passive convection wood fireplace keeps our 1560 sq ft home (with a 21 ft cathedral ceiling, loft and 36 windows) a comfortable 70 degrees. Even though average temperatures were below normal, we used only 2 pickup truck loads of wood. Our total heating cost for November through January was only $225. Seeing is believing! This home is exactly what we hoped it would be. Partnering with the right team made building it an enjoyable experience. If we ever have to live somewhere else, it will be in a SIP/ICF house and we sincerely hope Extreme Structures will be our partners again.
