With the goal of decarbonization and sustainability of buildings in the sense of the circular economy, for integrated lighting systems the so far purely energy-based focus must be broadened to include the entire life cycle, with special consideration of visual and non-visual user requirements. In the task, strategic, technical, and economic information will be developed for the relevant stakeholders and networking activities will be offered.
Solar water heating will play a crucial role in the decarbonization of the energy system for 2030 and beyond. IEA SHC Task 69 focuses on two technologies which are likely to play the biggest role in the global solar hot water market: thermosyphon and photovoltaic (PV) hot water systems. For these technologies global market surveys, systems and component optimizations, cost reduction analyses and revision of standards are being conducted to accelerate growth in target markets.
This Task aims to push forward the compact thermal energy storage (CTES) technology developments to accelerate their market introduction through the international collaboration of experts from materials research, components development and system integration. These technologies are based on the classes of phase change materials (PCM) and thermochemical materials (TCM). Materials from these classes will be studied, improved, characterized and tested in components.
Regarding the use of CO2-free technologies for local/district heating systems, solar technologies in particular offer an efficient option. In this task, the opportunities and challenges are investigated in order to efficiently provide the required temperatures necessary for local/district heating networks through solar technologies, to promote digitalisation, to identify new business models and measures for cost reduction, and to spread the knowledge about the potential of solar district heating systems.
IEA-SHC Task 66: SOLAR ENERGY BUILDINGS - Integrated solar energy supply concepts for climate-neutral buildings and communities for the "City of the Future”
The energy supply for climate-neutral buildings is based on holistic system concepts that achieve high renewable fractions by intelligently combining technologies, sector coupling, high grid interaction and flexibilization measures. The Solar Energy Buildings Task supports exactly this development. The objective is to identify relevant stakeholders and their needs, to develop a technology portfolio and optimised integrated energy concepts and to give recommendations to policy makers and energy-related companies.
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.
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.
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.
