ECONOMIC SUSTAINABILITY | SOSTENIBILITÀ ECONOMICA

Thanks to its compactness, the building envelope is optimised for minimising construction and energy costs. A rational, vertically executed load-bearing system, the use of prefabricated elements with a high repetition factor and the use of only 3 window formats also ensure low construction costs.

Rental/sale cost compared to market price
Costo di affitto/ vendita rispetto al mercato The SMART – apartments combine compact living with very favourable equilty and rents. The tenants´s contribution is € 56/m2 for the utilit value and the rental costs are € 6/m2. In addition, cost-optimised planning while ensuring the high qualities the flats are below the specified tenant costs.

SOCIAL SUSTAINABILITY – SOSTENIBILITÀ SOCIALE
Rules of allocation – Regole di assegnazione: The project offers a diverse range of flats and a differentiated distribution of different types of housing for example smart 40, smart 55 and smart 70. The focus groups are young families, couples and singles who, for example, still need housing that is as affordable as possible.

Protection of fragile categories
Tutela categorie fragili: The project offers a diverse range of flats and a differentiated distribution of different types of housing. The “smart” flats are distributed throughout the building complex and optimally integrated. This means that there can be no social segregation or discrimination

Involvement of inhabitants in the building process – Coinvolgimento degli abitanti nel processo: Through an interactive internet platform, interested parties were given the opportunity to define their flat themselves according to their needs and requirements. The location of the flat in the building, the size of the flat or the size of the private free space for example can be defined.

Community accompaniment in the life of the building – Accompagnamento della comunità nella vita dell’edificio:
In the building, “punctual” communal facilities such as the communal room, the sun deck and the barbecue area form communication zones and meeting places. In addition, the arcades on the courtyard side with adjoining communal and adjoining rooms on each floor create optimal conditions.

ENVIRONMENTAL SUSTAINABILITY
SOSTENIBILITÀ AMBIENTALE:
Functional mixitè – Mix funzionale
The project also has different types of open spaces. Open arcades repeatedly expand generously into meeting zones. Each flat has a private outdoor area that can be individually designed and serves as a filter layer to the noisy street space.

Common spaces and shared living – Spazi comuni e abitare condiviso:
An elaborately designed square is the identifiable entrance for the building’s residents as well as an attractive public zone with shops on both sides. In addition, communal facilities such as a sun deck are distributed throughout the building and serve as a communication zone.

ENVIRONMENTAL SUSTAINABILITY
SOSTENIBILITÀ AMBIENTALE
Techniques and strategies for environmental saving:
Ecological building and technical measures improve the living value, such as windows made of wood/aluminium with insulating glazing or an energy-saving lighting concept. Thanks to its compactness, the building envelope is optimised for minimising construction and energy costs.

Description of the project:

PROGRAMME/FUNCTION
The “smart living” programme is an occasion to rethink traditional solution patterns and architectural images and to develop new social, aesthetic and structural qualities in housing construction.

A highly rational, cost-effective and flexible building structure serves as a basis for diversity, new options and participation. It becomes a sign of identification not only for the residents, but also for the neighbourhood and beyond.

Smart living does not mean restrictions or even discrimination for the residents. Rather, the choices of all residents are expanded – whether in “smart” or “normal” living.

URBAN CONTEXT
The urban configuration shows a roadside building that directly connects to the existing neighbourhood. In the cityscape, the new building has a metropolitan-urban linearity. The street-side orientation of the flats underlines this model of urban living. The ground floor zone, which is dominated by workspaces, shops and offices remains to transparent. An elaborately designed square as new piazza is either the identifiable entrance for the building’s residents or an attractive public zone with the shops.

The design of the building continues familiar urban planning principles of the street-side development. However, the metropolitan, linear building structure is individualised by private open spaces of the balcony zone in front. The design has a high identification value: a diverse balcony structure on the street side, colourful and varied arcades inside the courtyard.

DESIGN APPROACH
The development of a well-functioning neighbourhood also requires a balance between privacy and community and needs the possibility of open and lived communication. Despite the small living space per person in the “smart” living programme, the suitability of the floor plans and the private open spaces for everyday use is enhanced by this participation concept and the possibility of “appropriating” central, communal areas.

The idea of this communal rooms is based on a new interpretation of the Austrian traditional ‘Basena’. Originally Basena was the only watering place of the house in the stairways, but it developed into a general meeting place. In this project the arcades are repeatedly expanded into informal meeting zones, and communal areas such as laundry rooms, etc. are housed in “hand-held” colourful boxes.

ENVIRONMENTAL SUSTAINABILITY
Geiwinkler&Geiswinkler Architects have designed a total of 148 flats to a low-energy standard, of which 116 are ‘smart dwellings’ with different sizes.

The theme of ‘smart living’ is a compact variable housing concept for small, low-cost dwellings. This concept ensures low user costs. The tenants’ contribution is € 56/m2 for utility value and the rental costs are € 6/m2.

ECONOMIC SUSTAINABILITY
The concept of compactness of flats optimised to minimise construction and energy costs. This is achieved through efficient insulation thicknesses, as well as the installation of a ventilation system with heat recovery in the street-facing areas of the ground floor.

The life-cycle costs to be expected in the long term are very low over the entire life of the building thanks to high energy efficiency and a construction method that can be easily deconstructed, as well as an open space concept that is cost-effective in terms of construction and maintenance.

SOCIAL SUSTAINABILITY
The position of “smart dwellings” are distributed throughout the building complex and optimally integrated. This means that there can be no social segregation or discrimination.

Through an interactive internet platform, interested parties were given the opportunity to define their flat themselves according to their needs and requirements – for example the size of the flat and the size of the private free space.

Besides the private free space, there are “punctual” communal facilities in the building such as the communal room on the ground floor. In addition, the courtyard-side arcades with adjoining communal and adjoining rooms on each floor create optimal conditions for communication and participation.
