Team website: www.purdue.edu/inhome/

The INhome, Purdue University's U.S. Department of Energy Solar Decathlon 2011 entry, offers a realistic and balanced vision for ultra-efficient housing. The INhome—short for Indiana home—is an innovative, yet practical, house that meets the needs of a typical Midwestern consumer in today's cost-competitive residential market.

Design Philosophy

The INhome blends technological innovation with functional aesthetics to create a living space that appeals to homeowners. It is practical and cost-effective because of its reliance on passive design, which uses natural processes to reduce heating, cooling, and lighting needs. The Midwestern-inspired INhome demonstrates some of the many ways to live sustainably without sacrificing quality or comfort.

Features

Although the exterior of the INhome could blend in well in a typical Midwestern neighborhood, the house's design includes many special features, such as:

  • A self-watering biowall with vertically arranged plants

  • Interior finishes that contain pre-consumer or post-consumer recycled content

  • A multi-process air purification system that removes airborne contaminants.

Technologies

The INhome exhibits a number of efficiency technologies in its mechanical systems—all of which can be effectively and economically implemented in residential applications. These include:

  • An air-to-air heat pump that serves as the primary heating and cooling source

  • A heat pump hot water heater that uses the ambient air inside the house to produce hot water

  • Carefully placed ductwork that allows for conservation of warm and cool air as it is distributed throughout the house.

Market Strategy

The INhome's target client is a young professional couple, currently without children, in the market for a home in Indiana. The house, which is divided into private and public spaces, features a master bedroom with access to a west-facing porch. The full bathroom includes two sinks so multiple residents can use the space simultaneously. An extra room provides space for a home office or second bedroom.
