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.
In "Enerspired Cities" the concept for an automized junction of judicial secured access regulation to (geo-)energy data is elaborated. This will be adapted to the specific situations in the cities of Innsbruck, Salzburg and Vienna and implemented in dedicated pilot applications. The declared aim is the support of urban planning, monitoring and research by an easy and transparent access to base data coming from various sources for a wide range of users.
The city of Melk has set itself the goal of playing a pioneering role in renewable energy supply and climate protection. In this context, an initiative is aimed at implementing Positive Energy Districts. Two urban development projects are currently underway to examine under which framework conditions, technical and organisational solutions Positive Energy Districts can be realised. A proactive participation process aims at informing developers and investors as well as other stakeholders about the realization of PlusEnergy concepts.
Stanz+ is working on the implementation of an energy strategy for structurally weak municipalities with specific measures for revitalisation and re-densification in the building stock as well as the integration of renewable energy sources in the municipality of Stanz im Mürztal (Styria). The project includes multipliable approaches towards energy autonomy, hybrid use of energy networks for flexible usage and an energetic revitalisation of the village centre with the involvement of users in the "Rural Pioneers Community" for the usage of energy services.
The project explores paths to a sustainable, future-proof Positive Energy-District (PED) in the area surrounding the location of the University of Applied Sciences Vienna (FH-Technikum Wien). The feasibility of a new university building as a Plus-Energy teaching building will be examined in detail to prepare its implementation. Central innovation contents are the energetic flexibilization of the new building and the quarter as well as the conception of the Plus-Energy building as a "Living Lab".
Development of testbeds and demonstration zones within already designated areas for urban development along the Graz-Gleisdorf Innovation-Axis with a focus on energy, integrated building technology, smart city-spaces, compact settlement structures, generational living, and ‘cities of short ways’. It will pay specific attention to intermodal mobility as well as ICT-based solutions.
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.
DIM4Energy - Digital Information Models for the Planning and Optimization of Buildings and Urban Energy Infrastructure
Digital information models (DIM) are playing an increasingly important role in urban planning and decision-making processes, from individual buildings (BIM) to urban information models (UIM). For the planning and optimal operation of plus-energy neighborhoods, valuable information could be obtained from these existing models, provided the appropriate data sources and associated software tools are properly linked.
MehrWertStrom 2030 - PV-Community system - Exploring a participatory pilot project with regional added value for structurally weak regions
The "MehrWertStrom 2030" project analysed the legal, technical, organizational and economic feasibility of PV community joint venture facilities on multi-party buildings including the added value for structurally weak regions and developed innovative solutions related to organization, financing and realization.
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.
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.
Possibilities and requirements of transferring the Swiss “2000-Watt Site” certificate to Austria
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.
VITALITY District - Optimized energy concepts in the early planning phase of resilient, energy-efficient neighbourhoods
The aim of the VITALITY District project is to coordinate the total (electrical and thermal) load and generation profile in the design phase of urban areas and neighbourhoods in order to optimize the energy concept of energy-efficient districts. Hence smart city indicators in detailed level (buildings, individual technologies, public spaces) as well as models, principles and catalogs of criteria for energy-optimized urban neighbourhoods are going to be created. The results are going to be presented in compact form on the district level in order to serve as input for future urban planning projects.
The objective of this research project is to design a methodology for developing data and process models and to apply them by modelling selected MEP systems. A particular but not exclusive focus is put on the renewable heating technologies, e.g. heat pumps, solar heat and biomass as well as ventilation systems. The data and process models developed in this research project will be scientifically evaluated in two pilot projects. The models, the approaches taken during development and the project team’s experiences with the pilot application of the models will be disseminated openly.
The goal of the project is to link 3D city models and virtual reality for energy-relevant applications as key-enabler for digital planning, construction and operational management. Missing data will be calculated using statistical enrichment methods.
The core of the project P³Power is the measurement technology NetDetection, which is able to detect the power consumption of a household from any point, e.g. a regular wall socket. Based on this technology a plug&play powerplant, consisting of photovoltaics and battery pack, is realized. The system is able to guarantee 100% self-consumption within flexible aggregates (from single households to whole communes) without any changes of existing infrastructure. The measurement technology will be implemented into digital hardware, evaluated comprehensively in lab and household environment and subsequently new energy service business models are developed.
