How can Zero Carbon be realized in a project like “Zukunftsanker”?

An OPEN LAB event on the topic of„Carbon sink in a concrete applicationl“

In Vienna’s 10th district, the “Zukunftsanker” is being built on the site of the traditional Anker bread factory: a climate campus and center of excellence for all companies, professional groups and stakeholders involved in climate protection, sustainability, renewable energies and the circular economy.

The goal is to develop a CO2-neutral and urban neighborhood through a combination of preservation of the historic building stock and redensification. Experts and interested laypersons will discuss the topic.

The innovation laboratory RENOWAVE.AT for climate-neutral refurbishment would like to generate generate “knowledge for and with everyone” – on the basis of the concrete case of occasion “Future anchor” is to consider:

How can climate neutrality as a new self-image be incorporated into the further development of the stock?

Program:

15:20 with a guided tour of the premises

START: 16:00

WELCOME Peter Ulm and Michaela Mischek-Lainer (ALLORA)

PROJECT OUTLINE Claudia Nutz (Future Anchor) “On the Project Status Future Anchor”.

INTRO “What is climate neutrality, anyway?” (Arbeitsgruppe wissenschaftliches Board)

OPEN PANEL DISCUSSION:

• “How can Zero Carbon be realized in a project like the Anchor?”
• “How can we minimize CO2 emissions?
• How can we create CO2 sinks in refurbishment?

From 17.30 Drinks and snacks in the courtyard

Summary

The site is dedicated to the farm, most of the buildings remain, large concrete arch hall, guided tour of the site. There are several discussions with the city of Vienna.

Afterwards welcome Michaela Mischek-Lainer (ALLORA)

2 presentations:

1. PROJECT OUTLINE Claudia Nutz (Future Anchor) “On the Project Status Future Anchor”.
2. INTRO “What is climate neutrality, anyway?” (Arbeitsgruppe wissenschaftliches Board) Renate Hammer presents

OPEN PANEL DISCUSSION:

• “How can Zero Carbon be realized in a project like the Anchor?”
• “How can we minimize CO2 emissions?
• How can we create CO2 sinks in refurbishment?

discussing are:

• Claudia Dankl (VÖZ)
• Johann Marchner (Wienerberger Österreich, und FBI),
• Claudia Nutz (Zukunftsanker),

• Reinhold Lindner (ZIB),
• Roland Zipfel (FVSK) und
• Renate Hammer (IBRI)

DISCUSSION PROTOCOL :

There are also new achievements in cement development that lead to a reduction in Co2 emissions.

Concrete also has the ability to absorb Co2 from the air through the pores.

Low temperature solutions must be planned for the area, there is already a concept from IBRI. With a reconstruction, the uses must also be supplemented.

What becomes important is: how do you calculate remediation – so that it doesn’t get out of hand.

The brick building is historic and from that you can see how long this building material can last. Nevertheless, the building envelopes must and can be renovated and improved.

Today we are at 20% recyclability. See also Recyclingatlas. Atlas Recycling. Buildings as a material resource by DETAIL – Iss

Brick is recyclable.

But it’s also about upcycling the neighborhood.

To what extent does research help us? Has everything already been researched? Discussion about it, conclusion: “We need to research and do to make a difference” And then build the swarm intelligence, how do we do it?

Today, we’re also at a point of scaling. At Zukunftsanker, they think differently: belief in the project is important, and the companies involved should also move into the premises. We need producers at the table! So it is quicker to implement, but before in detail and plan together. How can we solve this well:

Spatial planning must be questioned. The processing is very complex. Funding in the re-think and re-use phases and RFPs are too rigid. The re-think phase in particular needs to be rethought.

A system change is needed.

RENOWAVE.AT is seen as the point of contact for all concerns related to system change. Elaborate the levers, present them visibly and start the dialogue with policy makers. Where are the levers?

There are too many calculation tools, it is confusing with the many tools and certifications.

The Co2 calculation is too complicated – in order to move forward faster, we need to approach the politicians. Identify 3-5 topics that are important and present them in a simplified way.

How do other countries do it?

One issue is insurance:Is there joint liability insurance?

Let’s sit down together for this once – set up doodle

But basically, the renovation measures are planned as follows:

1. Insulation: Good insulation can reduce the energy consumption of the building, which leads to a reduction in CO2 emissions.

2. Renewable energy: Installing solar panels, heat pumps or other renewable energy sources can minimize CO2 emissions from building operations.

3. Green roofs: Green roofs can help filter CO2 from the air and thus act as CO2 sinks.

4. Rainwater harvesting: Using rainwater can reduce water consumption, which in turn minimizes CO2 emissions from water heating.

5. Use of sustainable building materials: By using sustainable building materials such as wood, clay or natural stone, CO2 emissions from the production of building materials can be reduced.

6. Greening: Greening facades or courtyards can absorb CO2 and act as a CO2 sink.

7. Recycling: By using recycled building materials, CO2 emissions can be minimized by producing new building materials.
