Hereby, different international examples, options and processes for planning and implementation of solar energy measures in cities throughout the world have been screened, outlined and equipped with recommendations for further development. The core outcomes of the project address different options and possibilities for optimization of planning processes, framework conditions, tools, methods and education aiming to attain more effective and timely understanding as well as integration of solar energy in urban context.
IEA SHC Task 52 focused on the analysis of the future role of solar thermal heat in integrated urban energy systems. The potential of solar thermal applications to cover the low-temperature heat demand in future low-carbon energy systems was investigated against the background of the rapidly changing framework conditions in the energy sector. Best practice examples for the integration of solar thermal systems into urban energy systems were evaluated and documented.
Within the framework of the IEA SHC Task 53 'New Generation (NG) Solar Cooling & Heating Systems', solar-electric and solar-thermal air-conditioning systems were investigated. The main objective was the development and documentation of reliable and economical NG system solutions. A comprehensive comparison of different NG systems as well as the elaboration of support measures for the market launch are core results of the international cooperation.
IEA SHC Task 54 was an interdisciplinary, collaborative project with the main focus on significant price reductions of solar thermal systems. Measures to achieve a reduction of the customer price up to 40% included simplified system designs, standardized components and cost-efficient materials and production and installation processes.
Despite the large potential for integrating large solar thermal plants into district heating and cooling networks, the share of solar heat worldwide is below 1%. The aim of this project was to analyse the technical, economic, and regulatory barriers that hinder a faster market development of such systems, and to propose solutions to support the growing heat market. The results (roadmaps, data, information) are available in the form of fact sheets.
IEA SHC Task 56 focused on the critical analysis, simulation, laboratory testing and onsite monitoring of envelope systems entailing elements that use and/or control incident solar energy. The central task was the integration of HVAC and lighting systems into a building’s Solar Envelope solution through a systemic approach.
The goal of the IEA Task participation is to further expand and integrate the Austrian scientific experts in the field of compact thermal energy storage in the international research community and participation into the expertise developed. All national participants have the opportunity to integrate the results of their own R&D projects into the Task, and enable further positioning and integration.
IEA SHC Task 59/EBC Annex 76: Deep Renovation of Historic Buildings - Towards lowest possible energy demand and CO2 emission (nZEB)
The aim of IEA SHC Task 59/EBC Annex 76 is the documentation of best practice examples, the development of a multidisciplinary planning process and the development of holistic reconstruction solutions for historic buildings. In addition to the lead of Subtask A (knowledge base), the Austrian participation will also incorporate and further develop results that have been achieved in national demonstration projects and have been tested in practice.
Lighting accounts for 19% of the global electric energy consumption, and major savings can be achieved by intelligently connecting daylighting, electric lighting and control systems. At the same time, optimal visual and non-visual conditions must be provided for the user. Within this project the user requirements for lighting solutions and existing and novel control systems will be analyzed and documented. For evaluation purposes a consistent scheme for the characterization of daylight systems and an hourly rating model for integrated solutions will be worked out. Using a monitoring protocol, implemented integral lighting solutions will be evaluated in lab and field studies.
The main objective of IEA SHC Task 62 is to increase the use of solarthermal energy in industry, to develop newcollector technologies and to open up industrial and municipal water treatment as a newarea of application with high market potential for solar thermal energy. The nexus between solar thermal energy and water treatment enables the development of newand innovative technology combinations and the change to a sustainable, resource- and energy-efficient industry.
Since 1977 the IEA Solar Heating and Cooling Programme supports joint research and development activities in the field of solar thermal technologies focusing solar thermal for heating and cooling of buildings, for industrial applications and in agriculture.
Retrofitting of non-residential buildings with energy efficient daylight and artificial lighting solutions can significantly contribute to reductions in electric energy consumption. However, appropriate technologies have to be made available to the stakeholders (investors, industry, consultants, designer) that are involved in the retrofitting process. Thus, system solutions for daylighting and artificial lighting were evaluated, simple rating and evaluation tools were developed and case studies that serve as best practice examples were monitored. The results were collected in the Lighting Retrofit Advisor, which helps stakeholders within the lighting retrofit process.
The main objective of the task is to identify, verify and promote the role of SHIP (Solar Heat in Industrial Processes) systems as single system and in integrated energy systems. Technical and non-technical barriers will be tackled. The main results of the project are a dimensioning and integration guideline for SHIP and integrated energy systems and a Guideline to Market for SHIP and integrated energy systems.
Without measures, cooling demand will triple by 2050. The aim of Task 65 is to adapt existing technologies to the boundary conditions of the sunbelt, to find suitable system concepts, to evaluate them and to disseminate the advantages. In addition to system adaptations, the Austrian focus is on life cycle cost-benefit analysis and the further development of existing assessment tools.
IEA-SHC Task 66: SOLAR ENERGY BUILDINGS - Integrated solar energy supply concepts for climate-neutral buildings and communities for the "City of the Future”
