"ERnteLAA": healthy and sustainable living

  • BUWOG's "ERnteLAA" project makes healthy and sustainable living possible and brings the highest quality of living to the 23rd district
  • Close to nature in the city: from urban gardening on the rooftop to structural greening and environmentally friendly mobility
  • Sustainability with a social conscience: focus on affordability and good neighbourly relations
  • Upon completion, the transfer to tenants has taken place

As is well known, autumn is harvest time. For BUWOG this year, this is the case in a double sense: with "ERnteLAA", the completion of a housing project, whose design is especially sustainable and ecological, can be celebrated. And as the name implies, it permits its residents sustainable urban living in a natural environment. The extensive measures carried out in this project include the creation of a wide variety of green areas, façade greening and rooftop gardens, the use of ecological building materials, energy supplied by district heating with an integrated heat recovery system, and a wide range of services for environmentally friendly mobility. Andreas Holler, managing director of BUWOG Group GmbH: "At BUWOG, sustainability is an integral part of our philosophy of 'happy living'. We're convinced that healthy and attractive urban housing will be sustainable today and in the future. And our green projects such as "ERnteLAA" make an important contribution to a liveable Vienna by improving the microclimate and promoting biodiversity."


Green, greener, "ERnteLAA"

Planned by M&S Architekten, the "ERnteLAA" showcase project comprises 31 privately financed rental apartments and 160 rental apartments in the scope of the Viennese Housing Initiative; the floor areas range from 51 sqm to 116 sqm.

The tenants can expect a comprehensive sustainable concept from the front door to the penthouse floor. Problematic building materials were avoided and ecological materials such as low-emission wall paint were used instead.

The lush façade greening is visible from afar by means of trellises for climbing plants. Gardens open to general use are located on the rooftop. The intensive greening not only makes the complex climate-resilient against increasingly frequent weather phenomena such as persistent heat and heavy rain: the plants can retain rainwater and release it at a delay, thus easing the strain on the sewage system and preventing flooding. They also evaporate water, creating a cooling effect that noticeably improves the quality of life while saving energy costs. While the climbing plants on the façade act like a natural curtain, the extensive greenery helps insulate the building against heat and cold. The south-facing range of loggias also serves as large-scale sun protection. The energy supplied to "ERnteLAA" via district heating and an integrated heat recovery system is therefore supported and made more effective by natural means.

The plantings also reduce noise and pollution, which has a positive effect on health and well-being.

At the same time, the following can make an important contribution to greater biodiversity: the installation of 22 nesting boxes for building-related animal species will provide a home for protected species such as swifts, house swallows and bats, but also the house redstart and titmice. A wild bee hotel is being installed to preserve the bee population.


Urban gardening with perspective

Liesing, one of the districts with the highest proportion of green areas in Vienna, offers residents an attractive environment for living between city and countryside. The remaining structures with vineyards and wine taverns feature a certain village charm, while the Vienna Woods recreational area and the river Liesing enable living in a natural setting not far from one's doorstep. This is continued directly at home: the rooftop gardens provide every opportunity to become a gardener, for a healthy diet through the cultivation of fruit and vegetables, and they contribute to waste avoidance and reduced consumption of imported goods. In addition to large gardens plots and raised beds, there are greenhouses for overwintering potted plants and for cultivating young plants, where sowing and pricking out can take place regardless of the weather. A glassed-in lounge equipped with floor heating makes it possible for gardeners to meet and socialise at any time of year. The private balconies are also equipped with raised beds, and all open areas have a water connection for watering the plants. In addition to the rooftop gardens and balconies, sunny terraces, loggias and private gardens at "ERnteLAA" are an invitation to enjoy outdoor life to the fullest without having to leave home.


Environmentally friendly through city and countryside

Of course, a broad range of mobility options is an important element for a high quality of life today. But in cities, in particular, ecologically compatible and space-saving forms of mobility are needed to provide clean air and less traffic noise. At "ERnteLAA" a variety of solutions have been found to create the best conditions for this.

Meischlgasse is optimally connected to the public transportation network: with the U6 (Erlaaer Straße station) located in the immediate vicinity, it is possible to reach Karlsplatz in just 25 minutes, with Vienna's local trains (Badner Bahn at the Neu Erlaa station) in half an hour. In order to promote public transportation, every household receives an annual pass for Wiener Linien when they first move into the building.

For getting around in the city in an environmentally friendly way, residents have two charging stations for electric vehicles, a car-sharing electric car for rent and electric bicycles for hire. Bicycles can be stored safely and securely in 400 bicycle parking spaces, and private cars can be parked in the building's own underground garage.


Sustainability with a social conscience

What is special about "ERnteLAA" is not only the sum total of sustainable measures, but also the social component, which the concept has always encompassed. This concerns first and foremost the affordability of the apartments: "Our aim is to combine sustainability and affordability and to create a balance that is beneficial for the environment as well as for our target groups. "ERnteLAA" calls attention to the fact that ecological housing in Vienna is to be accessible to a broad section of the population," Andreas Holler explains. This is done by offering 160 apartments under the Vienna Housing Initiative and by providing an in-house family-friendly infrastructure featuring a kindergarten, supermarket and pharmacy.

To create the best possible conditions for the development of a neighbourhood community from the very outset, upon initial occupancy, the professional neighbourhood management organisation of Caritas will be involved. Until about 15 months following handover to the residents, Caritas will accompany the project, organising residents' events and helping garden the raised beds. For gardening not only offers the tenants a green lifestyle, it also promotes social interaction and cohesion. It is especially the integration of social sustainability measures that gives the project a special status compared to other buildings, according to Andreas Holler. "Our project is aimed particularly at those who know what is good for the environment and who wish they could do even more. However, the need for social interaction and community is also growing, particularly in otherwise such anonymous big cities. "ERnteLAA" offers its residents both – residents will not simply live next door to one other, they will live and shape the future together, and to a large extent sustainably."
