Our Services

We are a full-service Passive House design firm. We offer consulting, design, planning and engineering services from first meeting to occupancy. We have delivered certified Passive House buildings in North America since 2008.

We are on a Mission

At TE Studio, we feel that it is important to create buildings that deliver on many levels of design, sustainability and performance to provide your with real measurable results and amazing value.

We are experts dedicated to beautiful, durable, functional, and earth-friendly building designs that offer healthy environments and economy to meet your needs now and in the future. We practice Passive House design–the world’s leading building energy standard focusing on superior energy efficiency and quality of life at low operating cost. While originating in Germany, the founders of Passive House were deeply inspired by the energy conservation movement in the U.S. in the 1970s. We feel that Passive House in the U.S represents a perfect blend of the American spirit of invention combined with German engineering. We pioneered this world-class standard in the U.S. to provide you with measurable, leading-edge performance and results. We successfully designed Passive House buildings in one of the most challenging climates on earth and welcome the opportunity to do the same for you wherever you are.

TE Studio is holistic design for sustainable buildings.

What We Believe In

We are motivated by our Clients’ challenges and respond with experience, confidence, and patience to help pioneer the highest level of sustainability in building design. Our holistic approach delivers ultimate performance and efficiency blended with beautiful and functional design.

Tim Delhey Eian

Dipl.-Ing. Arch. (Architectural Engineer)
Certified Passive House Designer and Consultant (p3829)

You could say Tim was destined to have a career in architecture. At age three he followed construction progress of his new family home in Germany with fascination. As a young teenager he worked as an intern with his parents’ architect. Already realizing his life’s passion, he further prepared himself by mastering the foundations of woodworking in a carpentry apprenticeship, earning the prestigious title Master Carpenter. He later graduated with honors, earning an architectural engineering degree (Dipl.-Ing.) from the Technical University of Kaiserslautern, Germany. Tim has over 20 years of experience in both Germany and the U.S.

Deeply influenced by exposure to stringent German environmental policies throughout his formative years, he has a strong conviction that protecting the earth for humankind is one of the key challenges of his generation.

With the desire to take architecture to a new level of sustainability, Tim founded TE Studio in 2008. The same year, he started designing the first certified Passive House home in Wisconsin, which is also the first to offer plus-energy levels of performance in the country. Tim also designed the first certified Passive House projects in the TwinCities and Michigan.

Tim founded Passive House Minnesota—now a chapter of the Passive House Network—and was a founding board member of the Passive House Alliance U.S. He is a visiting lecturer at the University of Minnesota, and many other continuing education venues. He and his wife are raising their two children bilingually in Northeast Minneapolis. Their family-home, the Good Energy Haus, is Minneapolis’ first certified Passive House Plus new construction home.

Tim and his firm have been instrumental in educating and transforming how Minnesota owners, developers, municipalities, legislators and building professionals think about high performance buildings.
