Photonic Cooling – Efficient cooling of buildings through the use of photonic

Within the scope of the project a photonic cooling approach was investigated and evaluated in terms of feasibility and cost efficiency for building applications. In particular cost-efficient photonic surfaces and concepts were investigated which need to have a high reflectivity in of the incident solar radiation (>97%) and a high emission coefficient within the spectral range of 8 – 13 micrometer in order to enable the emission of heat into the sky.

Existing building reconstruction and implementation of passive house components

Implementation of passive house components, systems and techniques into the practice of existing building reconstruction, in order to reduce the energy consumption as much as possible and to increase the living quality substantially. Craftspeople and planners, who are specialized in building renovation, should gain access to passive house know-how.

OptiMAS - Optimization of building energy efficiency through model-based energy flow analysis with non-invasive sensors

Using a model-based energy flow analysis supported by non-invasive sensor technologies OptiMAS investigated how to monitor, analyze and optimize existing buildings independent of the installed HVAC systems and automation components. With the OptiMAS approach the optimization potential of individual buildings up to entire areas can be detected, located and tapped by adjustment of system parameters to ensure highest energy and resource efficiency.

DAKTRis - Dynamic operational behaviour of absorption chillers in Trigeneration Systems

In the present project an absorption chiller will be adapted to meet the specific requirements necessary to integrate it with the CHP unit. By means of hardware-in-the-loop measurements and dynamic system simulations, different system configurations and control strategies will be analysed under dynamic boundary conditions, optimized and evaluated.

Smart ABC Smart Energy Efficient Active Buildings and Building Clusters

The EPBD recast 2010 targeted "nearly zero energy buildings". This low amount of energy is to be covered by energy from renewable energy sources. The project "Smart ABC" analysed a variety of relevant solution sets regarding the building performance and the renewable based energy supply options. Energetic and ecological impacts were analyzed in order to optimize the integration of renewable energy technologies in building standards and to find answers how to depict a building cluster regarding standards and tools.

Building as living lab - Buildings as a living lab for climate-neutral, needs-based and affordable housing

Within ÖWG, climate protection and sustainability are strategically anchored in renovation and densification projects. A comprehensive, climate-neutral renovation concept had been developed for a specific pilot property in Graz in an open, co-creative innovation process. The building becomes a living lab in which new solutions are tested in the everyday lives of the residents.

IEA SHC PVT Task 60: Applications of Photovoltaic/thermal (PVT) Systems and New Fields of Application and Examples of PVT

The international research collaboration IEA SHC Task 60 (Application of PVT Collectors) identified existing applications for PVT technologies and evaluated and highlighted potential system solutions where PVT technology has clear advantages over separate installation of PV modules and solar thermal collectors. In analogy, their advantages and current barriers for a broad market acceptance were highlighted.

Participation in TASK 25 "Solar Assited Air Conditioning of Buildings". Description and Analys of the state of the art, development of a simulation tool, build up and measurement of demonstration plants.

IEA HPT Annex 57: Showing flexibility benefits through heat pump implementation in multi-vector energy systems and thermal networks

This project analyzes the future implementation of heat pumps in multi-vector energy systems and thermal networks. This is intended to increase flexibility and to use it for various applications, e.g. for system services or to participate in different electricity markets. Using international case studies, influencing factors and potentials for flexibility options will be evaluated and suitable business models will be derived.

i3 - Sustainable Food Management II

The project at hand is the continuation of the last years project of the same name. It is the aim of the project to develop an integrated, IT-based management model for a meat processing enterprise taking into account the value chain as well as the regional environment.

IEA SHC Task 61/EBC Annex 77: Integrated Solutions for Daylighting and Electric Lighting

Lighting accounts for around 15% of global electricity consumption - intelligent coordination of daylighting and electric lighting solutions together with integral lighting controls enable significant energy savings. At the same time, the solutions must be optimally planned in a user-centered approach based on the visual and non-visual effects of light. The task analysed user requirements as well as existing technologies and design methods and documented exemplary implementations in case studies.

Energy package Kolpinghaus / Eco-Suite Hotel

The Kolping association’s dormitory for pupils and students has been extended. The energy demand of the newly constructed Eco-Suite Hotel is minimized by use of highly efficient components (such as LED lighting). Locally available energy sources (waste water heat and sunlight) are used and an on-site energy system is being created for the use of the heat energy surplus. Guests at Eco-Suite Hotel can experience life in a plus energy building.

MODESTORE - Modular High Energy Density Sorption Heat Storage

Seasonal storage of solar heat for use in low energy and passive houses (new buildings as well as old buildings).

Quality criteria for the Building of Tomorrow

Development and implementation of contributions to the quality control of innovative technologies in the areas of building services and insulation that are derived substantially from HAUSderZukunft findings.

Inhabitants-friendly passive house renovation in Klosterneuburg / Kierling

Renovation of an apartment house from the 1970s as passive house using renewable energy.

Climate neutral Wiener Neustadt 2040

Wiener Neustadt wants to develop its own vision and implementation strategy for climate neutrality by 2040 and develop it in four steps.

IEA EBC Annex 71: Building Energy Performance Assessment Based on In-situ Measurements

The requirements on building envelope and on building technology are steadily increasing. There is a lack of measurement and analysis methods to control the quality of the built implementation and to optimize the building operation. This project developed a methodological basis to enable an in-situ evaluation of the actual energy performance and building operation. For this purpose, it investigated methods to generate data-driven building models favouring the use of already available on-board data.
