Passive House design optimizes the light, air, and thermal energy of a building, reducing building energy use by as much as 75%. It’s the world’s most rigorous building energy standard, charting a straight path to zero carbon building. It's a better way to design and build, with revolutionary performance and predictable results. It also complements programs like LEED and Living Building Challenge by providing a predictable and cost-effective way to meet energy and IAQ targets.
Passive House design delivers superior indoor air quality, thermal comfort, and building durability. Passive House buildings create gracious interior environments in which to live, work, and learn – quiet, comfortable, and infused with fresh air and natural light.
Careful engineering of the building envelope and systems optimizes:
Passive House design is based on the physics of building science and how buildings work as integrated systems. Our architects and designers collaborate to marry form and function, tapping advanced computer modeling to optimize building performance, comfort, air quality, and cost.
With over 150,000 built examples around the world, the superior performance and cost parity of Passive House construction are driving the exponential uptake of passive buildings around the world.
Whether you’re a developer or policymaker, certainty is vital. You need to know how buildings will actually perform before you invest in a development project or a policy solution. Passive House provides predictable energy, comfort, and air quality results, with unparalleled correlation between modeled and actual building performance. You’ll know exactly what to expect from the finished product.
I was working as a physicist. I read that the construction industry had experimented with adding insulation to new buildings and that energy consumption had failed to reduce. This offended me – it was counter to the basic laws of physics. I knew that they must be doing something wrong. So I made it my mission to find out what, and to establish what was needed to do it right.”

We understand that projects need to pencil to get built, no matter how worthy their social and environmental goals. NK Architects’ EcoProforma tool allows us to align architectural design and energy engineering with the specific financial goals of your project. Using this process, our zero carbon buildings can generate higher return for you.
