Passive House

Koss design+build is a member of the Passive House Alliance, is one of only two certified Passive House builders in all of Arizona and is the only certified Passive House builder in the Phoenix metro area.  Passive House is a unique, third-party building standard focusing on energy efficiency, superior indoor air quality and thermal comfort.  A typical Passive House building will consume 70% – 90% less heating and cooling energy than a typical code built home.  Site planning, super-insulation, pre-conditioned fresh air, tight envelopes, advanced building skins and thermal bridge analysis are some of the main components of any Passive House project.

Net Zero

Designing and building projects to a net zero level is an option we review on every one of our projects.  A net zero building can produce all the energy it will consume over the course of year.  Often net zero homes can create more energy than they use.  When paired with battery systems, net zero homes can be off grid if needed.  Many of the same principals used in Passive House certified projects are used on net zero homes.  Passive House certification, however, is not required to be a net zero residence.  Renewable energy sources, typically solar, are used to bridge the gap from a high-performance home or energy efficient home to a net zero residence.

High Performance, Healthy Homes

Regardless of budget, aesthetics, or energy efficiency goals, we collaborative with all project team members to create beautiful, high performing, healthy homes that meet the specific goals of our homeowners.  Consultants and subcontractors are specifically selected for each project to insure we are using the best tool for the job.

Limiting Volatile Organic Compounds (VOCs) and other specific chemicals such as formaldehyde are common requests from some of our clients.  Using sustainably sourced materials such as FSC certified veneers and reclaimed wood as well as recycled products are just a few of the ways we work to create healthy, more sustainable homes.

PROCESS

We approach each project with a 5 step process
that delivers quality and excellence to all of our clients.

DISCOVERY

Let’s meet at your project site or our office.  Once we get to know you and your project we can prepare a detailed proposal.

DESIGN

During the design phase we analyze your goals, the project site, review code/budget parameters and develop the project design concept.

DOCUMENT

The documentation phase is where we generate the drawings, specifications and documents that will be used to build, estimate, and permit your project.

DEVELOP

Throughout construction we orchestrate the budget, schedule, and craftsmanship to construct your one-of-a-kind, custom home.
