Austria: Gaspoltshofen
The main goal was to construct a low energy house in respect to
economic and ecologic issues. In addition a further supposition
of the owners was an attractive and appealing outfit. Of course
sustainability and the use of material of the region was granted.

Austria: Vienna
The demonstration-project “passive housing” Utendorfgasse
7, A-1140 Vienna” was implemented in a research project founded
by the Austrian Government (BMVIT). The goal of the research project
is the development of a building concept for the employment of passive
technology in social housing. The houses are financed by an semiofficial
housing company. The building project should be finished in 2005/2006.
The apartments will be rented.

Cernosice
Traditionally shaped, private built, single family house was built
in 2003. A building site for this private built house was set by
regulating plans, which do not respect optimal solar orientation
(in general: when assigning orientation of building, roof type and
other parameters, spatial planning does not consider factors of
sustainable housing, mainly optimal solar orientation). Therefore,
gables had to be south-north oriented and solar collectors had to
be placed on the porch.

House W
Using a minimum amount of materials and total primary energy from
non-renewable sources was the leading idea of the project. The house
should reach the low-energy house level with usually accepted costs
for standard housing. Both of these facts have led to a wooden-based
construction with simple form, energy effective building envelope
and use of several components typical for passive houses. The Uvalues
of the building envelope are close to those recommended by CSN 730540-2
(2002) Thermal Protection of Buildings, Part 2: Requirements.

Building envelope is based on a new open woodframed building system
Nordic Platform allowing for shorter delivery cycle than with typical
construction. Special features of the system are 250 mm wood- frame
with thermal break for exterior walls and trussed construction for
internal floors. The walls have an air tight additional exterior
insulation layer facing air cavity and wooden façade. Insulation
thicknesses and corresponding Uvalues including thermal bridging
in construction are 275 mm (U=0,15 W/m2K) for walls, 450 mm (U=0,15
W/m2K)for floor with crawl space foundation, and 500 mm (U=0,10
W/m2K) for roof. Windows are triple glazed with one argon gas filled
sealed unit and one selective coating. Total U-value including frame
is 1,1 W/m2K.

In 1996, a timber-construction double house was built in Durbach
near Freiburg within the framework of the "Weber 2001"
project. One half of this building was conceived as a low-energy

The ISIS solar passive apartment block is situated in the recently
developed residential area, Vauban, a former military barracks area
in Freiburg. The fourstorey apartment building, which was built
within one year, has been occupied since its final completion in
June 02. The passive solar apartment block has nine maisonettes
and four one-storey dwellings with heated floor areas from 77 to
145 m². The construction of the owner-occupied flats was commissioned
by the building group ISIS.

families. The dwellings are rented to the inhabitants. The two apartment
buildings with 40 dwellings in total are situated in the redeveloped
urban area of Marbachshöhe in Kassel. Up to the late nineties
military barracks have been located there. In this brochure one
of the two buildings (realized by HHS1) and ASP2)) with 23 dwelling

in the ground floor area, but sheathed with timber in the top floor
area. The wall has a Uvalue of 0.15 W/m²K.

In collaboration with major manfacturers of building materials,
the municipal housing society (NUWOG) of the city of Neu-Ulm, Germany,
raised 3 semi-detached buildings that were designed as 3-litre houses
within the framework of a model project located in Ulm. The term
'3-litre house' applies to low-energy buildings, whose annual primary
energy demand for heating figures below 34 kWh/m²a (including
the auxiliary energy required for pumps and fans).

Outer wall of this house, Hybrid Z, which is a laminated wall of
234 mm thick based on new ceramics (PALC) of 80mm thick, wraps around
the whole house. Windows, which have great thermal loss, employ
3-layer glass sash, which improves thermal insulation and air-tightness
of housing itself. Realizing a house that is naturally kept cool
in summer and warm in winter positively serves to suppress excessive
energy consumption in airconditioning.

Japan: OMSolar
House
The OM Solar system operates on the principle of taking solar-heated
air collected under the surface of a building's roof and channeling
this hot air, via an interior vertical duct, down beneath the ground
floor to a heat-storing concrete slab. This concrete slab warms
the ground floor and releases hot air through floor vents for distribution
throughout the building's interior spaces. Auxiliary devices come
into operation for hot water supply and for backup heating on overcast
or very cold days.

system using sunlight. Solar power is a clean source of energy,
and unlike oil and coal, is inexhaustible and does not produce CO2
emissions. The home was built with many factory-prefabricated members
which were then assembled at site.

As a result of the fact that this project is built in the body
of the dike which is constructed on more than 15 m of soft peat
ground below sea level, and because of the pressure on the dike
caused by heavy rainfall upstream on the rivers Rhine and Meuse,
it was necessary to make the concrete pile foundations extremely
heavy.
