Would you like to slash your current home’s heating bills by over 75%?

Passive House for existing buildings is possible!

Compared to starting from scratch, there are certainly more challenges when retrofitting existing buildings to Passive House levels of energy efficiency.

For example, most existing homes do not have the best orientation and shading for optimal solar gains, or may not have the option to thicken the walls for insulation by 100-400mm due to limitations of interior room dimensions or the set-backs to lot lines. Foundations and headers are harder to deal with. Existing houses are also more challenging to air seal than new construction.

EnerPHit recognizes these limitations, and allows for relaxed certification requirements for space heat demand and air leakage, yet without compromising the highest energy retrofit standard in the world.
