To compete in the Solar Decathlon 2013 Team Austria developed the LISI house: a compact,
sustainable interpretation of the atrium typology for one or two individuals, adaptable for
a range of climate zones.
The residential heart is a spacious, transformable living area that accommodates a variety of
lifestyle activities, such as cooking, dining, socializing, entertaining and relaxing.
Large sliding doors open to the partially enclosed patios, expanding the central living
area both to the north and the south.
Adjacent to the cooking area, the patio herb garden draws its water supply from the roof
The structural core of LISI contains the bathroom and a bedroom that can be alternately used
as a home office. The core also extends to pergolas flanking the patios at either end.
Changeable architectural layers create a variety of sensory conditions. LISI can close up into
a protective cocoon for its occupants, or open up to express their place in the neighborhood.
We set out to engineer LISI as a home environment that generates more energy than it consumes.
In other words, it’s an “energy+” system.
Photovoltaic modules cover the roof for grid-connected power generation, with a smart load management
system to optimally balance the energy flows in day-to-day operation.
Beyond heating and cooling, these include energy for warm water, home appliances, and
The utility room in LISI’s structural core houses all of the automated mechanical systems.
Here we have the PV monitor, system bus, and switchboard, as well as the compact ventilation
unit, plumbing controls and hot water supply, charged by an array of thermal collectors.
To avoid overheating on hot, sunny days, effective shading is provided by automated screen and
awning systems. The R&D process also involved optimizing the building in terms of overall
resource consumption.
Our little LISI is built mostly of wood-based materials.
All the construction components are shipped here in just six standard freight containers.
Since we’re dealing with fully pre-fabricated units, we can handle the entire component
assembly on-site with a single mobile crane and a solid construction crew. Disassembly
and reassembly are just as clear-cut and simple to get done.
Once LISI’s done her job here in California and wherever else she’s headed, we can easily
break all of her components down for clean recycling and material re-use.
We developed LISI mindful of the issues we collectively face for a sustainable future
as individuals and as societies inhabiting this planet.
The LISI house is a social animal, eager to find its own place in a closely spaced, yet
richly diverse community – with a sense of stewardship in using our most precious
