In GEMA, the project team will study and analyse the energy consumption of at least 10 commercial and residential buildings in Austria, which include innovative technologies or concepts for minimising their energy requirements. The results will allow for the potential optimal performance in terms of energy, environmental and social indicators of buildings in future construction projects.
Evaluation of solar-thermal energy stores using a uniform and marketable system of characteristic numbers
Comparison of solar-thermal energy stores A clear and uniform system of characteristic numbers enables a cost-saving comparison of the efficiency of solar-thermal energy stores of different technologies for the first time and gives important impulses for the market.
The energy demand calculated in the design phase often differs from measured values in the actual building operation. This projects reviews building automation and operation by presenting a solution how to assess energy efficiency of control strategies in the fields of air conditioning systems, concrete core activation and free cooling. The results are implemented in the demonstration building "Post am Rochus".
ARIS - Application of non-linear control engineering and implementation of intelligent sensor systems for the improvements of energy efficiency in the building sector
The major goal of the project was the development of innovative control concepts for controlling and optimizing heating, cooling and ventilation systems (HVAC) as well as building loads. The implementation of advanced, energy efficient non-linear control techniques in building management systems is supported by new sensor technologies that are applied to building and energy systems in order to improve their energy-efficient operation.
SaLüH! Renovation of multi-family houses with small apartments, low-cost technical solutions for ventilation, heating and hot water
New innovative concepts for heating and ventilation will be investigated. Very compact heat pumps are developed in such a way that it will be possible to integrate these units into the window parapet or into a prefabricated timber façade.
Within this project the intensive use of thermally activated building elements (TABs) as an additional thermal storage in different buildings, with solar technologies (thermal, PV) preferred for energy supply, was investigated. The aim was to activate and use the thermal storage potential that is immanent in the building elements and thereby achieve solar coverage of the building's heat demand of nearly 100 %.
urban pv+geotherm - Innovative concepts for the supply of large volume buildings/ quarters with PV and geothermal energy
The use of renewable energies in inner city locations is mostly linked to higher costs andconsidered as problematic. The aim of this project was to optimize (cost and energy) heating (and where required, cooling) using geothermic and photovoltaic for an urban, densely-built development area. With the project´s findings it will be easier to ecologically and economically plan the use of renewable energies especially in urban areas.
The aim of this project was to advance the state of the art in the engineering of double-leaf building facades that facilitate natural ventilation while providing sufficient sound insulation. Realization of natural (window) ventilation is in some instances difficult due to a number of factors. Thereby, noise pollution (especially traffic noise) plays an important role. To address these issues, the project explored innovative solutions in terms of facade constructions for concurrent natural ventilation and noise control.
Development and coordination of indicators for energy and ecological evaluations of urban areas based on the Swiss 2000-Watt certification system. The results will be used for the development of a quality assurance system for urban areas similar to the klimaaktiv declaration for buildings and the e5 certification for communities.
SQUARE - A System for Quality Assurance when Retrofitting Existing Buildings to Energy Efficient Buildings
The project aims to promote a flexible quality assurance management for the retrofitting process. It leads to high quality renovations of residential multifamily buildings regarding energy improvement and improvement of indoor environment.
A robust, predictive controller which utilises weather forecast data to control thermally active building systems had been designed, researched and assessed in terms of energy efficiency and comfort compared to standard controllers, especially for cooling purposes. Simulations and real measurements using two "Test-Boxes" with thermally active building systems which are constructed and built for this purpose were used to analyse energy efficiency and comfort. Low complexity and transparency of methods and solutions should allow for transferability of all results to guarantee maximum usability for similar applications.
Gründerzeit with future - demonstration project 3: KA 7 Kaiserstraße - Innovative renovation of a listed Gründerzeit building
A demonstration of how innovative measures, with highly efficient and contemporary standards and taking into consideration comfort and energy consumption, can be applied to a heritage listed building.
Research on the influence of collector hydraulics, piping and the arrangement of plant components on the stagnation behaviour of thermal solar systems.
How much energy does a passive house actually save? Does a passive house pay-off by itself? What are the costs for maintancence? For the first time an approximation for the running costs of a passive house were systematically documented and compared.
Connection of innovative strategies and technologies to a holistic, resources-friendly plus energy building (FUTUREbase)
On the basis of a construction project in Giefinggasse 4 in Vienna the combination of new, innovative strategies and technologies to an integrated, resources conserving plus energy building with high signaling and multiplication effect had been tested for feasibility. A regional, energetical bond between the buildings TECHbase, ENERGYbase and the Klima-Windkanal had been developed.
The focus of the project is on quality assurance within the commissioning process with the aim to speed up and to improve the operational adjustment of newly constructed or comprehensively renovated buildings. The fragmented know-how which is hardly accessible for the relevant target groups will be consolidated and elaborated in the form of a practice guideline which will be directly applicable in commissioning processes in practice. In this way the project contributes to the development of a common, well-established standard for quality assurance within the commissioning of buildings.

Energy relevant and ecological monitoring studies of demonstration buildings, which were built in the framework of the program "Haus der Zukunft". The user acceptance should also be levied and displayed
Solarenergie Urban - Analysis and evaluation of the economic, energetic and architectural quality of urban solar energy buildings
This project developed energetic and economic optimised planning criteria for multi storey residential buildings for the integration of renewable energy systems in the building shell. The field of new construction and refurbishment had been investigated.
The project demonstrates the application of a solar active facade system in the course of the renovation of an existing building in order to achieve the plus-energy standard. Moreover, the effectiveness of the system will be demonstrated on new buildings and transparent components as well. The final outcome will be a manual for the application and implementation of the façade system focusing on the segment of specialists and skilled labour.
Reduction of cooling requirements through optimized urban structures and processes and design optimisation in building design (smartKB*)
Based on a systematic listing of appropriate methods, recommended actions have been developed to reduce the cooling requirements in new or renovated buildings on three levels: a) optimization and use of appropriate urban structures, b) design strategies and passive measures for building concepts, c) reduction of cooling requirements through integrated planning processes.
