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".
EnergyCityConcepts - Methods and concepts for the implementation of sustainable energy systems in cities
Two concrete model regions (small city Gleisdorf and urban city quarter Salzburg-Schallmoos) will be developed and tested using new methodical approaches (interdisciplinary urban and regional energy planning, modeling and simulation). Therefore, it is aimed to substantiate scenarios and concepts for the implementation of defined targets on technical, ecological and economic criteria.
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.
SynENERGY - Energy optimised settlement development by making use of synergies of energy efficiency, spatial planning and building culture
SynENERGY aims at an innovative, holistic approach to urban district optimization. The project targets a comprehensive analysis of the framework and urban development concept which includes not only optimisation of sustainable energy supply and use but also increased material flows (construction and disposal) at urban district level.
SIMULTAN - Simultaneous planning environment for buildings in resilient, highly energy efficient and resource-efficient districts
Synopsis This project enables the opportunity for an essential energy efficiency increase within overlapping buildings, to achieve the objective of resilient cities and districts with respect to a high quality of life, resource sustainability and energy efficiency. The goal is a workable tool based on a multidisciplinary planning approach, to support the decision finding process in order to design both refurbishment projects and new developments within a highly efficient city.
The concept of a smart city explicitly refers to a sustainable city development. To apply smart city concepts in practice, it is essential to develop practice- and profit-oriented business models (smart services), which at the same time generate social and ecological benefits. Smart services are developed for the application in three specific city development areas and their practicability is verified in a comprehensive stakeholder process with decision makers.
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.
In this project the application of a solid oxide fuel cell (SOFC) for energy supply (heat and power) of urban areas will be investigated. Due to the high temperature level of the produced heat it would be possible to use this heat for the energy supply of different heat and power consumers (residential buildings, industrial plants, etc.). One aim is to provide the SOFC-heat at several temperature levels in order to establish the advantages of the fuel cell. On the one hand the legal and market-based conditions will be evaluated, on the other hand the technological feasibility will be scoured by the use of CFD-simulation of the heat production.
PRoBateS - Potentials of planning and building legislation for energetically sustainable city structures
The aims of this project are to analyse planning and building legislation in order to identify barriers, potentials and suitable courses of action for energy-orientated policy measures. Specific policy recommendations are developed with a view to increasing the sustainability of energy-related city structures. For these purposes the project combines two different disciplinary approaches: a thorough legal analysis and a spatial structure and quantitative impact assessment.
Aim of the project Eco.District.Heat is to provide strategic decision-making support that enables Austrian towns and cities to deal with aspects of grid-bound heating (and cooling) systems in accordance with integrated spatial and energy planning from a holistic perspective when elaborating urban energy concepts.
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.
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.
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.
URSOLAR provides decision makers with a roadmap for the integrated use of solar energy in urban environments. The roadmap shows, how photovoltaics- and solar-thermal installations can be used in an ecological, economical and socially optimal way whilst considering legal requirements as well as infrastructural conditions in typical city quartiers and stakeholder interests.
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.
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.
KELVIN - Reducing the urban heat island effect via improving the reflective properties of buildings and urban areas
The aim of this project was to estimate the potential to reduce urban heat islands via low-tech measures such as the variation of the surface albedo, using the City of Vienna as an example. The project has also assessed the energy savings and greenhouse gas emission reductions due to the decreased energy demand for cooling as a result of such measures.
The project examines the challenges of urban manufacturing (UM) from the energy perspective and shows opportunities arising from the implementation of UM concepts for the future design of sustainable energy systems for cities.
The present research proposal focused on the possibility, implications and consequences of "inwards urban expansion" through densification of the existing urban tissue. In this context, densification is not only approached through known and common aspects of building regulations and guidelines, but in view of what is actually possible to achieve.
