Winterthur is working to phase-out gas connections from existing buildings. To achieve the transition, the city is articulating visioning, stakeholders’ engagement, support to households, DHC development, and the articulation of the local and cantonal legal framework. Currently around 2/3 of households replacing their heating systems every year choose low carbon and renewable-based solutions. The goal is to achieve 100% in the near future. Winterthur is part of the EU-funded DecarbCityPipes 2050 project.

Energy is increasingly becoming an integrated part of urban planning in Vienna. In 2020, the new city government declared its ambition to reach decarbonisation by 2040, which lead to acceleration of activities related to energy efficiency, transition and renewables. The energy demand for heating and cooling of buildings has the highest share of total energy consumption in the city. Therefore, the necessity for decarbonising the buildings sector becomes evident. In the World Café Session we would like to present how to set up a Heating and Cooling Plan for a decarbonized Building Sector in Vienna.

So far, positive energy districts and neighbourhoods (PEDs) have been predominantly researched from a technological and energy perspective, often with a focus on electricity and related to new buildings. In Cities4PEDs, the cities of Brussels, Vienna and Stockholm collaborate with experts from research, innovation and citizen participation and investigate how cities can adapt and use their planning and implementation instruments so that urban development results in neighbourhoods that produce more energy than they consume.
In this World Cafe session we will present the evolvement of Viennese instruments for collective renovation of the built environment. We would like to discuss with you different approaches to accelerate the renovation of existing districts. How do we move from retrofitting singular houses one by one to a collective approach?

What if you could heat and cool buildings only with renewable energy and by using the thermal properties of concrete? Buildings globally are responsible for 37% of the global CO2 emissions where about three quarters originate from heating, cooling and lighting systems. The thermal concrete activation (TCA) functionality can reduce this footprint to a minimum.
Built on the thermal properties of concrete, TCA enables the heating and cooling of buildings with the sole use of renewable energy powered by heat pumps. The system pre-charges buildings like batteries with energy that can be stored and released to heat and cool buildings when needed, at zero cost. So, times without sun and wind can be bridged.
Energy efficient, environmentally friendly and cheap, the thermal concrete activation in combination with renewable energy, smart design and low carbon concrete EcoPact, produced by Holcim, can play a major role in the decarbonization of cities and effectively accelerate the phase-out of fossil fuels in the built environment.

Facing unprecedented climate change, we must all challenge what’s possible to make our world sustainable. Trane Technologies (NYSE:TT) is a global climate innovator. Its strategic brands Trane® and Thermo King® bring sustainable, efficient climate solutions to buildings, homes and transportation. The team will showcase customer stories of how buildings in Europe are today being decarbonized in our cities with climate friendly heating and cooling solutions, and they will share their call to action for companies to join them on their mission of boldly challenging what is possible for a sustainable world. Sustainability isn’t a buzzword at Trane Technologies – it’s core to its strategy. In 2019, the company launched its Gigaton Challenge to reduce customers’ carbon emissions by a billion metric tons – the first in the manufacturing industry to have its targets verified by the Science-Based Targets Initiative and one of only 47 companies to be verified twice. Trane Technologies has also set a goal to reduce GHG emissions by another 50%. The 2030 commitments also include achieving carbon neutral operations across the company’s global footprint, a 10% absolute energy reduction, zero waste to landfills and net positive water use.
Considering that today most European buildings use gas or oil boilers for heating, we at Trane, are committed to using renewable resources available in nature as part of our contribution to mitigate climate change and reduce carbon footprint. Over decades, we’ve partnered with building owners and facility managers to understand their challenges and explore exciting opportunities, such as repurposing untapped thermal energy within buildings.
