ProKlim - Optimisation of Energy Efficiency of automated indoor climate systems by using weather forecasts
Investigation of the basic energy savings potential for buildings in commercial use by including weather forecasts as a variable. Additionally, a concept for integrating weather forecasts into the heating and air conditioning control systems in buildings is planned to be developed. Within the scope of the feasibility study, a detailed analysis of technological possibilities, including both hardware and software, will be conducted.
The present study aims to explore the application options for compact units (ventilation devices including micro heat pumps, developed for passive houses) in low energy buildings. Compact ventilation units for heat recovery, heating and domestic hot water shall bear the basic heating load, whereas peak loads shall be covered by newly-developed auxiliary heating equipment combined with intelligent control algorithms. This allows increased energy efficiency as well as cost effectiveness together with higher living quality and lower ecological load.
Based on the selection of suitable demonstration projects in Subproject 1 an innovative concept for passive and active building envelopes and energy supply of so called "Plus Energy Buildings" (renovation) has been developed.
SolarCooling Monitor - Evaluation of energy efficiency and operation modes of solar cooling systems for air-conditioning in buildings in Austria
Evaluation of ten newly installed solarthermal cooling systems in Austria as well as a large-scale plant in Lisbon to identify the plant’s performance using a monitoring analysis and comparing simulation.
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.
On the basis of our relieable CPC-collector SOLARFOCUS S1 we develop the CPC-lightweight construction collector to get more material efficiency and maximum output of solar hightemperature energy.
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.
The main goal was to establish a long-term cooperation for "Solar Cooling" between the Austria Solar Innovation Center (ASiC) and the Center for Sustainable Energy Systems (CSES) at the renowned Australian National University (ANU) in Canberra. Combining the competences of both institutes immediately offers the chance to boost the penetration of the European and the Australian market with this new technology for cooling in sustainable buildings.
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.
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.
In the course of DALEC an online concept evaluation tool for architects, building engineers, lighting designers and building owners was developed. Although easy to use, the software accounts for the complex thermal and light processes in buildings and allows a simple evaluation of heating, cooling and electric lighting loads. Not only energy, but also user behavior were considered (e.g. in terms of glare protection) and visual and thermal comfort were evaluated. This novel and innovative, holistic approach makes sustainable and energy efficient building design possible for new buildings as well as refurbishment.
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.
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.
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.
