 |1|[[.:speakers_corner:energy_efficient_retrofits|Energy efficient retrofits – NOW!]]|Wolfgang Feist; Jürgen Schnieders; Jan Steiger, Passive House Institute  |Low operating energy consumption of the existing building stock is crucial for climate protection. It also facilitates renewable energy supply. The energy expenditure for production is usually less significant. Many examples demonstrate how exemplary building renovations can be implemented in practice.|
 |2|[[.:speakers_corner:enerphit_for_a_climate-resilient_st._johann|]]|Rainer Pfluger, University of Innsbruck  |A roadmap to climate neutrality by 2040 was developed for the market town of St. Johann with districtPH. In addition, municipal energy monitoring and the potential offered by EnerPHit building refurbishment, PV expansion and efficiency improvements are presented using the example of the local indoor swimming pool.|
-|3|[[.:speakers_corner:serial_refurbishment_to_ph_standard|]]|Tanja Schulz  |If the building envelope is ambitiously renovated and the qualities in terms of airtightness, thermal bridges and ventilation with heat recovery are right, then well-coordinated HP systems can be used almost anywhere. In detail, all components must be sensibly matched to each other: the heating and cooling capacity of the building must be carefully determined and then the heat output of the heat pump must match the application and the respective building. |

The larger building achieves the EnerPhit+ standard and the additional costs for the high-quality energy design are relatively low, while the general refurbishment costs are very high.. {{:picopen:members_only.png?15}}|

-|5|[[.:speakers_corner:Thermal component|]]|Tobias Hatt  |Two pilot buildings worthy of preservation were refurbished to EnerPHit Plus in the SüdSan research project. One building with subsequent activation of the existing wall, the other with low-temperature radiators, as there was previously no heat dissipation system. The differences are shown in simulations. {{:picopen:members_only.png?15}}|

+|6|[[.:speakers_corner:sustainable_building_and_renovation|]]  |Benjamin Krick,Johannes Seibert  |Sustainable buildings require decarbonisation (stopping the burning of carbon), the efficiency revolution and the use of renewable energy. Carbon sequestration and the circular economy can also help. We illustrate this with a parameter study.|
+|7|[[.:speakers_corner:enerphit_retrofit_in_vienna|]]|Helmut Schöberl|EnerPHit refurbishments are an important basis for overcoming the problems of climate change and the best preparation for the future challenges of existing buildings. The three flagship EnerPHit refurbishments of Wilhelminian-style buildings in Austria are presented.|
+|8|[[.:speakers_corner:passive_house_in_the_existing_building_stock|]]|Gerhard Kopeinig|The presentation highlights the wonderful opportunity presented by state-of-the-art modernisations of the existing building stock and underlines that existing buildings with an optimised thermal envelope and the efficient building services concept of the Passive House standard represent the future for all building categories in use, all construction ages, and all regions. This is shown using specific examples of EnerPHit refurbishments of buildings protected as historic monuments (Velden Music School, Mondsee Town Hall and Semriach School), the EnerPHit Plus refurbishment of a residential complex in Bolzano as well as the retrofit of a detached house in Felden am Wörthersee.|
+|9|[[.:speakers_corner:oead_guest_house|]]|Günther Jedlicka|In 2005, OeAD student housing built the world's first student residence in Vienna to the Passive House standard. After 19 years, the client is still highly satisfied, as are the roughly 20,000 students who already lived here. Since then, a further 13 Passive House halls of residence have been built, 8 of which are presented here. The latest Passive House hall of residence is due to open in the centre of Innsbruck in 2025. In this video, the architect Betina Hanel presents this guest house project with 173 beds in 159 rooms in detail.|
+|10|[[.:speakers_corner:recovery_of_warm_water_electricity_nutrients|]]|Ernst Schriefl, Helmut Schöberl|The aim is to utilise the energy content of wastewater where it is highest, i.e. directly at the building. A sustainable wastewater system of this kind, customised to the specific needs on site, enables not only heat recovery but also the recovery of useful water, electricity and nutrients|
+|11|[[.:speakers_corner:active_volume_flow_control|]]|Gabriel Rojas|Cost-effective and precise volumetric flow controllers are an important component for the realisation of passive houses. A new approach, conceived in terms of ‘energy harvesting’, is intended to enable an active volumetric flow controller that supplies itself with electricity.|
+|12|[[.:speakers_corner:away_from_oil_and_gas_getting_ready_for_the_renewable_energy_package_with_enerphit|]]|Helmut Schöberl|The renewable heat package will create a lot of movement in Austria. Refurbishment to the EnerPHit standard is a forward-looking basis for switching to renewable energy sources, especially in order to be optimally prepared for future legal developments in the building sector.|
+|13|[[.:speakers_corner:sande_passive_house_sports_hall|]]|Bernd Steinmüller|As more than 10 years of measurement results and experience have shown, the ambitious pilot project has far exceeded its objectives and provided numerous impulses that need to be strengthened and consistently rolled out in the interests of the urgently needed energy and climate transition..|
+|14|[[.:speakers_corner:gaining_momentum_for_refurbishment|]]|Michael Kölmel|Building renovations are necessary but often challenging. However, if energy-efficient renovations are carried out at the same time, the rewards are high: significant energy savings, low energy costs and a high level of living comfort. Nevertheless, the effort involved remains a hurdle: apart from investment costs, there is dirt, noise, restrictions and uninhabitability during a lengthy period of work. This is where serial renovations come in: extensive, standardised prefabrication. Depending on the initial situation, even including a building envelope, is intended to simplify renovations, significantly reduce time spent on site, and of course save a lot of energy. However, quality often falls by the wayside. ELLER KÖLMEL Architects demonstrate how serial renovation can be successfully combined with highly energy-efficient measures to create sustainable buildings and neighbourhoods in their projects. This additional service of 'convenient' implementation and a pleasant construction site for all involved does not come for free. With appropriate funding, the concept is being implemented in social housing construction. \\ |
+|15|[[.:speakers_corner:Retrofit Have an impact|]]|Jessica Grove-Smith; Jürgen Schnieders; Jan Steiger|What are the main conclusions that can be drawn from the 27th International Passive House Conference in Innsbruck? Three CEOs of the Passive House Institute sum up the conference presentations and underline the most important takeaways of the rich, two-day programme which again showed that we already have effective instruments to mitigate climate change in the building sector. Now is the time to implement them. Hence, the imperative to dial up all retrofit efforts is clear, always in line with the motto: “If you retrofit, then do it properly and have an impact!” \\ |
+|16|[[.:speakers_corner:The Massachusetts Story|]]|Paul Ormond|Within 12 years between 2010 and 2022 the Massachusetts State, resp. most of its cities and towns did not only transform the main goal of their building codes from Energy Efficiency to Decarbonisation, but did voluntarily decide to enact a passive house standard for residential buildings as a mandatory standard. This thrilling story is now an example for other States in USA and not only there. \\ {{:picopen:members_only.png?15}}|
