What is a Passive House?

A passive house is an exceptionally energy efficient building that uses smart design and cutting-edge technology as a tool to maintain a precise comfortable indoor climate while reducing its environmental footprint. Passive houses can effortlessly remain comfortable and durable without relying heavily on external energy sources like active heating or cooling systems by using passive solar gain, insulation, airtightness, and controlled ventilation. This type of building not only ensures a high level of comfort but is economically beneficial as it reduces operating costs while contributing to a healthier environment for the occupants.

How does Phius compare to LEED certification?

When it comes to green building certifications, Phius and LEED (Leadership in Energy and Environmental Design) are two of the most well-known options. While both certifications aim to promote sustainable building practices, there are some key differences between the two.

Phius focuses specifically on energy efficiency and carbon reduction, with their certification program centered around the Passive House standard. This means that buildings certified by Phius are designed to use very little energy for heating and cooling, resulting in significant reductions in carbon emissions. In addition to energy efficiency, Phius also prioritizes indoor air quality and overall occupant health and comfort.

LEED, on the other hand, takes a more holistic approach to sustainable building, with certification criteria that cover a wide range of topics including energy, water, materials, site selection, and more. While energy efficiency is certainly a component of LEED certification, it is not the sole focus.

Another key difference between Phius and LEED is their certification process. Phius uses a performance-based standard, meaning that buildings must meet specific energy use targets in order to be certified. LEED, on the other hand, uses a point-based system, where buildings earn points for meeting certain criteria in various categories. The number of points earned determines the level of certification (Certified, Silver, Gold, or Platinum).

Ultimately, the choice between Phius and LEED will depend on your specific sustainability goals and priorities. Here is a diagram that explains some of the differences in green energy certification programs.
