Hemp Ski, Recyclable ski manufacturing from hemp, bio-resin and waste streams
In industrial production for alpine skis, epoxy resins of fossil origin and pre-impregnated glass fiber reinforcements are processed today. Innovations that replace environmentally critical materials in skis with biogenic substitute materials with an improved environmental balance have so far been limited to the production of small series. This circumstance motivated the consortium to develop a solution for a circular bioeconomy with the HempSki project, which will also make industrial ski production from renewable raw materials and waste streams possible in the future.
IEA-SHC Task 66: SOLAR ENERGY BUILDINGS - Integrated solar energy supply concepts for climate-neutral buildings and communities for the "City of the Future”
The energy supply for climate-neutral buildings is based on holistic system concepts that achieve high renewable fractions by intelligently combining technologies, sector coupling, high grid interaction and flexibilization measures. The Solar Energy Buildings Task supports exactly this development. The objective is to identify relevant stakeholders and their needs, to develop a technology portfolio and optimised integrated energy concepts and to give recommendations to policy makers and energy-related companies.
IEA EBC Annex 64: Optimised Performance of Energy Supply Systems with Exergy Principles (Working period 2014-2018)
To reduce CO2 emissions in cities, an overall understanding of energy conversion processes is necessary, which also takes temperature levels into account. This is particularly important when alternative heat sources such as waste heat, ambient heat, solar and geothermal energy are to be used, as these often have a low temperature level, i.e. a low exergy content. Accordingly, urban energy systems are analysed and optimised within the framework of the IEA EBC Annex 64 with the help of the exergy approach.
IEA DHC TS5 - Integration of Renewable Energy Sources into existing District Heating and Cooling Systems (RES DHC)
The expansion of sustainable district heating/cooling is an essential part of the Austrian heat transition. The transformation of these supply systems to fully renewable systems requires the combination of a multitude of aspects. The aim of the project is to compile a data and knowledge base from international projects in this context. Expertise and process know-how for the process of implementing the transformation of district heating and cooling systems will be collected and processed.
IEA DHC Annex XIII Project 07: CASCADE - A comprehensive toolbox for integrating low-temperature sub-networks in existing district heating networks
The majority of urban district heating networks operate at high temperatures, which are a barrier to the efficient integration of heat sources such as solar, geothermal, ambient or low temperature waste heat. CASCADE is investigating the integration of low-temperature networks into the return pipe of existing district heating networks, which will reduce return temperatures and thus improve efficiency and increase its capacity to connect new customers.
IEA DHC Annex XIV project 02 „FAST DHC - Feasibility Assessment Tool for District Heating and Cooling“
The transformation of district heating is referred to as the transition from the 1st to the 4th generation (4GDH). Recently, so-called ‘thermal source networks (TSN)’, also known as 5th generation or anergy networks, have been introduced. The aim of the project FAST DHC is to develop and demonstrate a simple tool for the techno-economic evaluation of 4GDH and thermal source networks, which also enables a comparison with individual heating and cooling solutions.
IEA DHC Annex XIV project 04: RE-PEAK - How to cover peak heat loads in DH networks with renewables?
One challenge for the decarbonisation of many district heating networks (DH) is the provision of peak load. The objectives of the RE-PEAK project are: to gain a better understanding of the specific problems, to collect empirical data on the provision of peak load, to analyse the perception of district heating network operators with regard to the transition to climate-neutral peak load coverage, and to consolidate the results and derive recommendations.
IEA DHC Annex XIII Project 02: MEMPHIS 2.0 - Advanced algorithm for spatial identification, evaluation of temporal availability and economic assessment of waste heat sources and their local representation
The identification and integration of waste heat sources is a key measure towards the decarbonisation district heating networks (DHN). Aim of MEMPHIS 2 is to develop an improved algorithm for identification of different current and future waste heat sources; including time relations of the heat emitted and techno-economic details as well as the further development of the online waste heat explorer.
InnoGOK – Investigation of the energetic and ecological usability of solar radiation on urban spaces and paths
Examination of the suitability of street space or other paved or not paved surfaces in urban areas for promoting renewable heat from solar radiation. Thus offers a high potential for increasing energy efficiency and conserving resources in urban contexts. Besides, the dissipation of heat from large solar-heated surfaces promises to prevent urban heat islands.
Stakeholder process of the initiative "Reference architecture for secure Smart Grids in Austria"
The project worked out the development of a smart grids reference architecture for Austria under involvement of all actors. Based on technological-scientific elements a process which met the requirements of stakeholders like operators of infrastructure, industry and also public agencies had been worked out to achieve nationally accepted and internationally orientated reference architecture.
PRoBateS - Potentials of planning and building legislation for energetically sustainable city structures
The aims of this project are to analyse planning and building legislation in order to identify barriers, potentials and suitable courses of action for energy-orientated policy measures. Specific policy recommendations are developed with a view to increasing the sustainability of energy-related city structures. For these purposes the project combines two different disciplinary approaches: a thorough legal analysis and a spatial structure and quantitative impact assessment.
Pallets never pall - Development of the Pallet House to series-production readiness
The winning project "Pallet House" of the EU-wide competition GAU:DI in 2007 consists of 800 (used) pallets. It has been exhibited in a scale 1:1 at the Biennale in Venice 2008 and has been developed for mass production within this project. Therefore, two exemplary scenarios were developed: (temporary) construction at Vienna's Urban Lakeside in Aspern and the construction of a low-cost building in South Africa.
