Passive House is called “passive” because it works even without fuel. Super-insulation, airtight construction, and high performance windows and doors will keep the interior comfortable without much need for energy. In the long run, this saves money and reduces environmental impact.
The PassivHaus movement took root in Germany in the early 1990’s. Tens of thousands of buildings around the world have received a Passive House Certification.
Studio.e uses software to create a detailed analytical model, and this helps to optimize the design. Comprehensive software goes beyond guesswork and general rules. A Passive House model balances the insulation thickness and glazing areas to benefit from solar heat gain without overheating, ensuring thermal comfort year-round. A Certified Passive House uses 90% less heating energy than a standard “code-minimum” home. Highly insulated construction also blocks noise, for a quiet indoor environment.
The Passive House design process begins with a detailed analysis of how the form, materials, and details all affect energy use and comfort. We zoom way in on the details to ensure air sealing and avoid thermal bridges. High-performance walls, roofs and floors must work together with advanced windows and doors to minimize energy losses during the heating and cooling seasons. Efficient mechanical systems (typically consisting of a heat pump and a heat recovery ventilator) ensure fresh air and thermal comfort.
With over eleven million square feet of Passive House projects completed worldwide, Passive House Certification has consistently produced the highest performing buildings in a wide range of project types and climate zones around the world.

Talking Dollars & Cents
It’s about spending a bit more to save in the long run.
The cost estimation process begins with a short schematic design process focusing on a dialogue between client, contractor, and architect. The classic “price per square foot” method is generally less accurate with passive construction due to unique features. However, you can roughly ballpark their overall cost at 10-25% higher than a comparable quality-built home.
Katrin Klingenberg, Director of Passive House Institute US states, “Passive House {Certification] is the cheapest way to build when taking life cycle cost into account”.
Passive Houses have an economically advantageous return-on-investment, with construction costs typically negating 80% of the utility operating costs in the home’s life cycle. Case studies in Germany show that Passive Houses can effectively recoup higher construction costs by saving on monthly energy billing. Many German homes in the study began generating net-positive savings before their mortgage was completed.
Good design is forward-thinking. Passive Houses are unlikely to incur remodeling fees associated with environmental energy optimization, and Certification is a marketable asset that can effect home resale value.

Check Out the Book
Passive House Details introduces the concepts, principles, and design processes of building ultralow-energy buildings. The objective of this book is to provide design goals, research, analysis, systems, details, and inspiring images of some of the most energy-efficient, carbon-neutral, healthy, and satisfying buildings currently built in the region. Other topics included: heat transfer, moisture management, performance targets, and climatic zones. Illustrated with more than 375 color images, the book is a visual catalog of construction details, materials, and systems drawn from projects contributed from forty firms. Fourteen in-depth case studies demonstrate the most energy-efficient systems for foundations, walls, floors, roofs, windows, doors, and more
