Why Passive Homes Will Be the Future of Home Building

As individuals and companies alike begin to consider more sustainable building options, Passive Homes are an excellent solution. Referred to as “Passivhaus” in German, this construction concept focuses on airtight insulation to create a living space that does not require additional heating or cooling.

Developed in the 1970s, developers have incorporated the PassivHaus design in homes all over the world and in a variety of climates. As an affordable, eco-friendly and versatile construction solution, these homes will play an essential role in the future of homebuilding.

Affordable

Professionals often regard eco-friendly building solutions as too expensive. While construction costs for passive homes can cost 5 to 10% more upfront than a traditional build, these fees are negligible compared to future savings. As sustainable options become standard, these costs may drop. Passive Homes rely on design principles that promote peak energy efficiency without external systems.

With a focus on proper insulation and minimizing air leakage, homeowners can save on conventional heating costs without needing to invest in expensive forms of renewable energy. While solar panels or other types of eco-friendly power are popular, because of the efficiency of the Passive House, their usage is minimal.

Adaptable

People build Passive Houses all over the globe in a variety of climates. The five main principles of passive homebuilding are versatile and can be altered depending on the environment. The airtight construction utilizes proper heat balance, ensuring that warm air remains inside in cooler climates, and properly ventilates in warmer ones.

 

Another nice feature of Passive Home construction is the ability to modify each project aesthetically. Unlike other forms of sustainable building, such as strawbale homes or shipping containers, professionals can construct Passive Homes using a variety of materials. This style does not limit builders to certain architectural styles. Because supplies can vary, many homeowners choose to add to the overall sustainability of their homes by using post-consumer building materials.

Eco-Friendly

Passive Homes are eco-friendly by design. In Europe, it’s the standard building practice of the future. According to The Resolution of the European Parliament, its implementation will be mandatory in new home construction by all member states in 2021.

The elements of Passive Homes are sustainable by default and do not require relying on alternative energy systems for primary energy. The standard principles are the result of research at the Passive House Institute, and include:

  • Airtight structures
  • Double and triple-insulated windows
  • Continuous insulation
  • Thermal sealing
  • Air quality management

Passive Home design principles do not rely on renewables as a primary source of energy, focusing instead on insulation and passive solar to maximize heat efficiency. They’re also the most affordable way to achieve zero-carbon, resulting in energy savings of up to 90% compared to conventional energy systems.

Passive Building for the Future

Passive Home design incorporates efficient ventilation, heat recovery and super insulation to create a high-quality structure that is not only efficient but also extremely comfortable. A contractor can adapt these buildings to any climate or design preference. While Passive Homes are already a standard — and future mandated — construction in Europe, they’re also becoming more popular in the United States.

Thanks to a U.S. Department of Energy “Building America” Grant, the PassivHaus Institute established new building standards that take into account market and climate variables throughout North America, including comfort and performance.

Any architect or contractor can easily utilize the Passive Home style, and the building standards are available via online distribution. As consumers and developers look towards a more sustainable and eco-friendly future, this style of building should be at the forefront of construction.
