A simplified method will be developed for the calculation of environmental indicators for so far not considered building elements (eg. constructions, which are not thermally relevant and HVAC-components). The theoretical principles for the calculation of the primary energy demand and the CO2-Emissions for operating and raising a building will be harmonized.
Manage_GeoCity - Development of a method for the coordinated management of geothermal energy in urban areas
Based on the urban region Graz a method had been developed for the coordinated use and management of shallow geothermal energy for heating and cooling as well as seasonal heat storage in urban regions. Ground water flow, different geologic conditions, heating and cooling demand, heat input from solar collectors and industrial waste heat and the possibilities of seasonal heat storage in the subsurface were considered.
The main goal was to raise awareness for energetic renovations of settlement houses due to the handbook "Neue Standards für alte Häuser" in Slovakia and the Czech Republic. In doing so, the refurbishment potential has been identified in the target countries, experiences exchanged and information transferred. Contacts to the relevant target groups have been established.
To assess the energy performance of urban planning projects in early design stages with low input and evaluation effort within the project CityCalc, an easily applicable planning and evaluation tool has been developed.
In the project ERP_hoch3 energy related policy research in three Austrian agglomerations (Vienna – Lower Austria, Graz – Styria and Vorderland-Feldkirch) has been done, scenarios of the current state and the target state have been modelled and calculated. The aim was to develop generic transferable recommendations for spatial energy planning in agglomerations.
PV4residents – Innovative Finance Service and Business Model for PV Power Plants of Multiple Dwellings with On-site Use of Electricity
The aim is to develop a business model, which enables a stronger penetration of PV plants on multiple dwellings with self-consumption of produced electricity by the residents. Involvement of the municipality allows to deliver surplus electricity for their needs. Basis of the business model is an analysis of the technical, legal, administrative, user related and economic barriers with participation of stakeholders and to identify best practice solutions.
AR-HES-B – Energy storage, production and recovery of valuable substances in wastewater treatment plants
AR-HES-B develops technologically based concepts of municipal wastewater treatment plants in order to convert them from energy consumers into a hybrid energy provider, energy storage and a provider of resources. The concept enables wastewater plants to turn into an important platform in the regional energy and mass transfer.
E_PROFIL is a set of methods (an IT-supported toolkit) for the elaboration of neighbourhood profiles. The aim of the project is to facilitate an energy and resource efficient development in the planning practice of Austrian cities. Furthermore, the project is an important asset for research and planning activities in Europe and can also be applied to other neighbourhoods.
HOTSPOTS enables new insights and perspectives for city development. According to the project idea innovations in acquisition and sensing as well as densification of geo-referenced city related data are supplemented by novel processing chains in city data analytics. Driven by an integrated scientific approach we develop a novel method in the selection, evaluation and prioritization of infrastructural city development measures which is directly derived from sensed data hence reducing the risk of ad-hoc decisions or lack in impact.
This project addressed the development of construction details for the implementation of vacuum glazing panels in new windows. In this project such constructions (form of frame, thermal bridges, structural aspects, mounting of glass) were explored via empirical experiments and via simulation. As an outcome, a mock-up was constructed, and the findings were documented in a comprehensive document.
Syn[En]ergy: Development of Potential Synergy Effects between the Interdependency of Urban Planning goals and Photovoltaic Usage on Open Urban Landscapes
Open spaces such as parking lots, brownfields and some categories of recreation areas offer an underutilised potential for photovoltaics in urban regions. In the course of Syn[En]ergy an inter- and transdisciplinary approach potential synergies and conflicts with other use demands were investigated, a typology and practical solutions for selected areas with regard to requirements from economy, urban planning and design, legal as well social aspects developed, and then evaluated by stakeholders from enterprises, administration and the general public.
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 %.
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.
Participation in CEN TC 350 (sustainability of construction works) - WG4 Economic Performance Assessment of Buildings
Participation in the CEN TC 350/WG4 to develop a standard to evaluate the integrated effectiveness of buildings during their life cycle. Evaluation and integration of national comments in order to prepare the standard for the final vote.
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.
This subproject of the flagship project "aspern plus" derived the basis for a centralised monitoring of the energy consumption in Seestadt aspern.
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.
The present project is based on the results of the project "The energy-efficient hospital: realistic departure points and identification of possible measures"
aspern Vienna´s Urban Lakeside - subproject 1: Public Space and Micro Climate: Basics for climate sensitive planning in Aspern
The Project will derive planning examples and recommendations in order to optimize the building performance as well as outdoor amenity. The study will be based on a climate prognosis of the aspern area and compare different reference examples of construction and open space design.
