Publisher: ACR - Austrian Cooperative Research, Online database

Im Rahmen des von 2014 bis 2017 laufenden Projektes „Vorgefertigte Fassadenelemente mit maximal integrierten HVAC-Komponenten und -systemen zur Bestandssanierung“ wurden neue Lösungsansätze für intelligente Bestandssanierung aufgezeigt bzw. entwickelt, wobei es unter anderem um die Synergieeffekte für die Modernisierung der Gebäudehülle und der Gebäudetechnik bei konsequenter Nutzung erneuerbarer Energieträger ging. Erklärtes Ziel dabei war die Erreichung eines hohen Vorfertigungsgrades in Verbindung mit Holz- Vorhangfassaden und damit kurze Sanierungszeiten mit geringsten Belastungen der Bewohner, reduzierte Abhängigkeiten von der Witterung im Sanierungsprozess sowie eine gesichert hohe Ausführungsqualität. Entsprechende Energieversorgungskonzepte stellen die auf die Fassade auftreffende Solarenergie effizient dem Gebäude zur Verfügung.

Hurdles and opportunities offered by the exploitation of the solar source through multifunctional envelope technologies Hurdles and opportunities offered by the exploitation of the solar source through multifunctional envelope technologies
December 2017 - PDF 0.72MB
Making use of the solar source is key in highly energy efficient buildings both to limit thermal and lighting needs and to cover the residual demands by means of technologies exploiting a high share of renewable energy. However, this requires the careful design of the individual technologies and the planning of their integration into buildings as they may eventually result in complex systems to operate and maintain, and the thermal and visual comfort of the users may not be guaranteed. Moreover, different strategies can be competing against one another (e.g., glare control against minimization of space heating demand) and finding an optimal solution is not straightforward.

DALEC – a novel web tool for integrated day- and artificial light and energy calculation

DALEC is a novel, combined lighting and thermal simulation web tool. This tool allows building designers to evaluate their individual façade concepts in terms of thermal and visual performance and ultimately their impact on overall building energy use. Although easy to use, the software accounts for the complex thermal and light processes in buildings, by way of sophisticated and time-saving pre-calculations. Based on climatic data a calculation of heating, cooling and electric lighting loads can be obtained within a simulation time shorter than one second. The model has been validated by comparison with experimental data and other state-of-the-art software and shows deviations less than 15%. Not only energy demand is considered, but also user behaviour (e.g. glare protection), as well as visual and thermal comfort. This innovative, holistic approach facilitates and accelerates the design of sustainable and energy-efficient building for new, as well as for refurbished buildings.
