Passive House design and construction is the most stringent energy standard in the world. Developed in Germany, this standard is the world leader in promoting energy efficient, comfortable and healthy buildings.
There are 5 main pillars of passive house
Air Tight Construction
Creating an airtight structure is vital in maintaining even temperatures throughout the building, and making the building durable. To meet passive house standards you must be under 0.6 Air changes per hour with the blower door running. This is at least 5 times tighter than New York State Building Code.
Continuous Thermal Insulation
Just like a winter coat, we want to make sure your house has continuous and sufficient insulation to keep out the coldest winter weather. To meet the Passive House Standard heating demand of 4.75 kBtu/sf/yr.
High Performance Windows and Optimal Orientation
Passive House windows are designed to let more energy in over the course of a heating season, than it lets out. We also want to optimize the shading to make sure we don’t over heat the house in the summer months.

Proper Whole Building Mechanical Ventilation with Heat/Energy Recovery
All Passive House Projects have designed and commissioned whole building ventilation. This system is designed to change out all of the air in the building every 3 hours with fresh filtered outdoor air. Up to 95% of the heat and up to 60% of the moisture is recovered to keep the energy in the house as well as superb indoor air quality – in many cases the indoor air is of higher quality that the outdoor air.

Thermal Bridge Free Construction
It is very important to eliminate any areas in the house that conduct the heat from the inside to the outside. These thermal bridges create potential cold spots inside the house which could lead to condensation and mold growth. Every thermal bridge point in the build will be analyzed and verified to be thermal bridge free.
