2050 energy concept for a mixed-use area

Development of an innovative energy concept for a new, location-independent, medium-sized site in Switzerland with different types of use. Global warming affects everyone. Global warming of at least 2 degrees Celsius is expected. This is also likely to result in a change in humidity and more extreme weather conditions. This will create new challenges for the built environment. The need for summer cooling will increase. At the same time, the increased use of sustainable energy sources implies seasonal energy storage. What must an energy concept for a site look like with a view to 2050 in order to do justice to these aspects and cover user needs in the long term? News. Three rough concepts were developed for the project, which were discussed and enriched by a panel of experts. The next step will be a synthesis workshop for the overall project. On this basis, the requirements for the degree of innovation for the energy concept will be derived. As the most progressive concept, it is conceivable to design and develop an energy concept with modeled climate data for 2050. The site would then be climate ready in 2050. Objective. The project team is aiming for an energy concept that can be implemented using a specific example in Central Switzerland. The aim is to comply with the Minergie-A-ECO framework conditions and supplement them with innovative elements - depending on local conditions. The ideal of a net-zero concept should be incorporated. Initial situation. The focus is on a medium-sized, mixed-use, non-urban site. The Energy Strategy 2050 in accordance with the SIA standards serves as the starting point. Responsibility for the project lies with Strüby Konzept AG, a leading Swiss full-service provider that not only relies on Minergie-A to achieve climate targets, but also promotes ECO construction to ensure the health and well-being of its customers.  

Energy Alternatives for an Asphalt Production Site

Reducing the CO2 emissions and optimizing the energy consumption in asphalt production. Alternative Energies will help to reduce the CO2 footprint of an asphalt production site. Asphalt production nowadays is mainly driven by the usage of fossil high-density fuels. Asphalt production companies are seeking for alternative solutions to make the production of asphalt much more sustainable. Moreover, the recycling of old asphalt harvested from used roads needs to be considered as well. News. A visit to Implenia site in Ecublens (VD) was performed to learn more about the asphalt manufacturing process and plant operation features. This recently overhauled plant is equipped with new technologies that aim at plant efficiency and therefore sustainability while improving productivity. This includes efforts to increase energy savings and reduce environmental impacts, improve plant versatility to better meet individual customer requirements and increase use of recycled asphalt in mixtures. The visit provided a good overview of the process requirements and pointed out current limitations and possible improvements areas for higher efficient and cleaner processes, some of them to be tackled in this project. Targets. The following questions should be addressed by this project: How can we run an asphalt production site with the minimum amount of fossil high-density fuels? How can we increase the thermal efficiency of such a plant? How can we increase the amount of recycled asphalt in the whole production process? Initial situation. Implenia as one of the project partners is seeking for optimized design solutions as they plan to overhaul existing Swiss production sites. Contact.

Renewable Energy on Neighborhood Level

Integration of renewable energy on neighbourhood level is a key point in reaching the goals of the Swiss energy strategy 2050. If the commitment of the goals of ES 2050 shall be fulfilled, the integration of renewable energy-especially for space heating and domestic hot water production-comprise one central key point. SFOE has lately started its own initiative on the topic. An interdisciplinary approach of social, financial and technical researchers will provide insights into the processes required to achieve this goal. Targets. The following points are addressed within the project: Bottom-up initiative concerning substitution of fossil driven heat converters on building/district level and best use of thermal energy storages. Integration of new renewables such as PV and utilisation of economy of scale-providing best ROI of capital invested Build a demonstration case to exemplify the possible decarbonization of buildings/neighbourhoods. Initial situation. The neighbourhood "Wesemlinquartier" in Lucerne serves as test case to roll out different approaches on electricity self-production, thermal conversion emitting CO2 and most fitting integration of thermal storages taking into account best revenues of capital. The public will be closely accompanied on a social research level to build a bottom-up initiative within the neighborhood to strengthen the case. Outlook and next steps. Already, eight industry partners could be bound and the social impact will be a key success criteria. Are you interested in contributing your expertise? Then let us know. Contact.

Connectivity in the building (KiG)

The "Connectivity in buildings" project has set itself the goal of increasing energy efficiency by improving the interaction between individual trades, disciplines and technologies through digitalization. Buildings are an immensely important area when it comes to achieving climate targets and using energy efficiently. Digitalization offers an important tool for this and can improve the well-being of residents. In order for it to contribute to the climate and energy targets, the interaction between the individual trades, disciplines and technologies must be improved. This is the aim of the "Connectivity in buildings" project. The results should advance digitalization in the building sector and help to leverage its potential. Background. Digitalization in buildings and sites is progressing rapidly. Be it through new technologies such as IoT, BigData, artificial intelligence, BIM, etc. or due to the incentives of new framework conditions, such as the Energy Strategy 2050 or the revision of the CO2 Act, which aim, among other things, to decarbonize the building stock. To ensure that the new technologies can be used to achieve the desired goals, fundamental questions about interoperability, data protection and cyber security - which are increasingly acting as barriers - must be asked. Existing barriers to system integration should be identified and addressed in a practical manner. Interdisciplinary cooperation between the individual trades, disciplines and technologies must take center stage in order to achieve the desired quality, security and effectiveness in the use of technology. As part of the "Connectivity in buildings" project, existing specifications such as standards, norms and guidelines are analyzed for existing gaps, overlaps and ambiguities and the necessary overview of the complicated standards landscape (big picture) is provided. Where possible, existing international standards and regulations are also taken into account. The interests of all relevant stakeholders and in particular the building operators are just as important as the technology and are identified in a market and needs analysis on the topic of connectivity in buildings. They are compared with the existing regulations and influencing factors and the consequences in terms of gaps and necessary regulations are derived from this. A guideline based on the project results should combine existing requirements into a comprehensible whole and supplement them where necessary. It should serve as a viable basis for improving a cross-disciplinary understanding of digital functions and processes between the trades, disciplines and technologies in the building and strengthening networking within the stakeholder groups. Objectives. - Creation of a market and needs analysis on the topic of connectivity in buildings in collaboration with the building sector - Recording of existing findings and creation of an overview on the topic of connectivity in buildings (big picture) - Identification of the need for action to achieve the desired target state - Creation of an initial draft of the guidelines - Promotion of interdisciplinary collaboration and networking between the individual stakeholder groups in the project (building investors, owners, operators, planners, integrators, technology manufacturers) Output. A map (big picture) is to be developed as an overview of all relevant contexts (standards, labels, specifications, programs, projects, initiatives, etc.) on the topic of connectivity in buildings and a guideline "Connectivity in buildings" with corresponding recommendations.

Smart Energy Home

Opportunities for intelligent buildings through the new Energy Act Every building is part of the energy ecosystem. Self-production and consumption play a key role in the planning and use of buildings. The new legislation brings new opportunities but also challenges for the members of the Innovation Park, which are being worked out on an interdisciplinary basis as part of a Smart Energy Homes working group. With the first package of measures for Energy Strategy 2050, the Energy Act was completely revised as of January 1, 2018 and self-consumption was newly regulated. As a result, new opportunities are on the horizon, which were examined and evaluated as part of the project, with the hope that these interdisciplinary findings can be incorporated into future products or offers. Objectives New business opportunities thanks to ZEV. How can self-consumption be optimized even more? This can result in a business model, but also a more stable electricity grid and thus a more stable supply, but also a smaller ecological footprint through the stakeholders involved. Results The project produced findings on three key topics, which were explored in greater depth. Self-consumption increases thanks to mergers, if this is permitted by regulatory/legal framework conditions. Due to the low electricity tariff for a ZEV, the PV system may have to be operated uneconomically, as the production costs are higher than the output tariffs. In order to operate a ZEV, only the minimum size of PV system required would therefore be installed. However, depending on the cost degression for larger systems, it may be possible to realize a medium-sized system at similar costs. With a performance price, a ZEV can achieve lower annual costs than without a merger. However, this depends on the additional costs incurred by the ZEV and the respective electricity tariffs. Capacity prices also offer incentives for load management of peak loads.
