Central and semi-central ventilation systems with heat recovery (“comfort ventilation”) still have enough potential for optimization regarding their energy balance (lowering heat demand vs. power efficiency), their economical application and their easy operation for users. One key question is the cost effectiveness usage for big residential buildings which is accepted within experts but not within […]
SolarGrids
Today about 20% of the residential heat demand in Austria is covered with district heat. Hence, the integration of solar thermal systems in heating grids could hold a large potential for the future deployment of solar heat generation. However, especially in urban areas heating grids are often supplied with waste heat from highly efficient CHP […]
SolarBrew
Brewing Industry Processes qualify themselves for the integration of solar heat because of their process temperatures. Processes with temperature ranges between 50 to 100 degrees C are very capable for the integration of solar thermal plants as the efficiency of solar collectors (flat plate and vacuum tube) in this temperature range is high. To accumulate […]
IEA EBC Annex 56 – Cost Effective Energy and Carbon Emission Optimization in Building Renovation
Starting point and motivation A significant reduction of the greenhouse gas emissions is necessary to slow or stop the climate change. The increase of the energy-efficiency of the buildings is a common implemented option but not the only determining criteria. The challenge to renovate our existing building stock is higher than to build new energy […]
Smart ABC
Starting point / motivation The Directive on the Energy Performance of Buildings 2010/31/EU (EPBD) requires “nearly zero energy buildings” and the coverage of this very low amount by “energy from renewable sources produced on-site or nearby”. The implementation of this standard in Austria (within legislative and strategic instruments) sorely needs: Contents and goals Ziel des […]
Solar Campaign 2012 for Styrian Municipalities
A information brochure on the topic is available (in German). Solaranlagen zur Warmwasserbereitung mit einer Mindestfläche von 6 m² Aperturfläche werden vom Land Steiermark mit € 50,- pro m² unterstützt, bzw. mit € 60,- pro m² Kollektorfläche bei Raumheizungsanlagen ab 16 m². Zusätzlich gibt es einen Sockelbetrag von € 300,- bzw. für Raumheizungsanlagen ab 16 […]
Green Brewery – Zero fossil CO2 emissions for breweries
Innovative energy concepts depending on the production capacity, the site and the products have been developed in case studies and possibilities of production without fossil fuels have been demonstrated applying energy efficiency, heat integration and a combination of renewable energy sources. Beside concepts for three breweries (Göss, Puntigam, Schladming) a “concept for Green Breweries” was […]
+ERS – Plus Energy Network Reininghaus Süd
Starting point / motivation Until now plus-energy houses were frontrunners: very often single family houses or buildings in sparsely populated areas. But due to the ongoing urban sprawl new solutions have to be developed. The focus should be set using the infrastructure options of urban areas in a better way: Supply networks, effluent disposal, public […]
PROMISE DEMO IF
The project PROMISE DEMO – IF and its „partner-project“ PROMISE DEMO are based on the preliminary project PROMISE APPLICATION. In the framework of PROMISE APPLICATION, several industry case studies with focus on energy efficiency and integration of renewable energies were conducted in the sectors of surface treatment of metals. For one of the participating companies, […]
Solar thermal sector concept for the food industry – Solar Foods
Starting point: The food industry uses large amounts of thermal energy in the temperature range 30° C to 150° C. It is possible to provide these temperatures with carbon-neutral solar thermal systems. The aim of this study was to create implementation-concepts for the integration of solar heat in the food industry sub-sectors in close cooperation […]
