What is passive home building?
Passive Homes are the international leading standard in high-performance, energy-efficient buildings. Through the use of technology and superior construction, they reduce a home’s energy use by up to 90%, saving the owner significant heating and cooling costs. They also dramatically decrease the home’s carbon footprint, making them very environmentally friendly. 

They have exceptional indoor air quality that is clean and comfortable while also providing a consistent indoor temperature. This building approach utilizes attention to energy modeling during the concept phase which is crucial to eliminate mold and condensation issues. To achieve this, we use special modeling software to determine the best approach for your home’s unique envelope — the envelope is composed of the roof, walls, floors, doors, and windows. This creates an airtight building envelope that is remarkably efficient and at the same time provides terrific ventilation.

Building a passive home or remodel is not more expensive than traditional construction. While there can be more upfront costs for materials, you will save money over the long run thanks to much lower energy bills and considerably less maintenance.

Passive home building is a construction process that produces a building that is energy-efficient, comfortable, affordable, and ecological. Through the use of technology, building materials, and superior construction, passive homes provide many advantages over traditional construction.

They can reduce a home’s energy use by 90%, increase and maintain the indoor air quality, and decrease the home’s carbon footprint. They also maintain an airtight building envelope with a consistent indoor temperature that pays attention to and eliminates mold and condensation issues.

A passive home is truly an advanced, high-performance home where you will quickly notice the difference and save money over the long run and provide the opportunity to faster mortgage pay-offs.

It is a founded myth that you have to invest more money to build an energy-efficient home. While material costs may be higher upfront, passive homes and buildings are extremely cost-effective in the long run. Passive homes will save you a lot of energy, reducing your monthly energy bill and ecological footprint.

No, the standard is the same because the Passive House standard's bottom line is meeting the performance values. Whether you are building one in cold Montana or tropical Hawaii, the standards remain the same. Different climates will dictate different building envelope details, however every structure does meet the same numerically evaluated standard.

Yes, you can! We have the experience and capability to convert your existing home into a passive home.

They use more insulation, creating a thermally resistant and airtight envelope. The home’s junctions are carefully designed to avoid thermal bridging and air leakage. They also have state-of-the-art windows that are built to command heat loss/gain. Ventilation is achieved by a Heat Recovery Unit (HRV) or Energy Recovery Unit (ERV), which transfers heat from exhausting air to incoming air, so the indoor temperature remains stable, controlled, and comfortable.
Lower your energy bill and enjoy comfortable indoor temperatures year-round
