BUWOG and klimaaktiv Pakt2020: the housing of the future is energy efficient


In the klimaaktiv Pakt2020, BUWOG commits to greater sustainability in the building sector.


As part of the klimaaktiv Pakt2020, twelve large Austrian companies have committed themselves to reducing greenhouse gas emissions by more than 16 percent within nine years, to increasing their energy efficiency and to obtaining at least one third of their energy from renewable sources. As a leading full-service provider in the residential property sector, BUWOG has made a significant contribution to the klimaaktiv Pakt2020. Through its increased focus on energy efficiency, a sustainable energy supply, ecological building materials, more efficient land use and climate-friendly mobility solutions, BUWOG has been able to drastically reduce its emissions, thereby advancing achievement of the national climate targets.

"The building sector is the second largest source of harmful environmental emissions in Austria. Here, BUWOG has a particularly significant source of leverage in its hands for climate protection, as our range of services covers the entire value chain in the housing sector – from project development to the management of existing buildings. With our model ecological projects we demonstrate that climate protection, comfortable housing and attractive architecture can go hand in hand very well, and at affordable prices for our customers," says BUWOG Managing Director Valerija Karsai.

Energy efficiency meets social quality

In terms of energy efficiency, there are considerable demands on the building of the future. BUWOG has therefore had two adjustments to make: on the one hand, around 850 of the existing units have been thermally refurbished each year to meet a low-energy standard. On the other hand, there has also been an increased focus on the optimal use of energy in newly constructed buildings. Each year, BUWOG builds between 600 and 800 residential units, which are to be constructed in accordance with strict energy efficiency criteria as part of the pact partnership. The minimum standards established in the building regulations have been exceeded by an average of approximately 15 percent. There is also compliance with the klimaaktiv standard for subsidised housing projects, which are expected to continue accounting for 50 percent of BUWOG's new construction output in the future.

A model project in this respect is the intergenerational housing project at Mühlgrundgasse 3 in Vienna's 22nd district. With its energy-efficient construction, the passive house with 54 housing units was able to reduce the heating energy demand by more than 80 percent compared to conventional residential buildings. An in-house solar plant as well as a vertical winter garden with over 1,000 green plants and a large number of common rooms show how sustainable and socially oriented the housing of the future can be. This innovative overall concept won the klimaaktiv Gold Standard for the residential construction at Mühlgrund.

Sustainable energy supply: from office to residential properties

"What we use to heat and cool our homes and where we get our electricity from is a central question on the road to climate neutrality. All properties in which BUWOG has a majority shareholding and all BUWOG offices are therefore supplied with certified green electricity. However, the in-house energy supply from heat pumps and solar installations is also playing an increasingly important role – particularly in new buildings," says Andreas Holler, managing director of BUWOG Group GmbH, who is responsible for development.

Cleaner mobility: around the world by rail

BUWOG has also broken new ground in terms of clean mobility as part of the klimaaktiv partnership. For example, business trips within Austria were largely made using public transport, electric bikes or electric cars. In 2019 alone, BUWOG employees covered a distance of around 48,700 km by rail instead of by car – that is more than just circling the equator. In addition, modern, climate-friendly mobility solutions are being consistently considered and tested in the residential complexes. In the course of new construction projects as well as with extensive refurbishments, the possibility of setting up electric charging stations is examined in detail and implemented where possible. This makes the switch to electric vehicles particularly attractive for residents.

Impressive record for the klimaaktiv Pakt2020

In order to help achieve the national climate targets, the twelve major Austrian companies Bank Austria, BUWOG, Canon Austria, Caritas Salzburg, Danone, Greiner Packaging Austria, hali büromöbel, Hoval, McDonald's Austria, Ölz Meisterbäcker, REWE International AG and Vöslauer Mineralwasser GmbH set ambitious targets for themselves. In 2011 they committed to reducing greenhouse gas emissions by more than 16 percent, to increasing their energy efficiency by at least 20 percent and to using at least 34 percent renewable energy sources (10 percent in the area of transport and mobility).

The commitment of the pact partners has paid off: the goals defined for 2020 were already achieved in fall of 2019. With consistency and a great deal of effort, they have contributed to a reduction of more than 1.39 million tonnes of CO2 since 2005 – equivalent to the emissions from around 200,000 flights around the world. As pioneering companies, the klimaaktiv pact partners show that energy efficiency, business success and climate protection can be easily combined.
