IEA-SHC Task 50: Advanced Lighting Solutions for Retrofitting Buildings

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 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.

IEA SHC Task 69: Solar Hot Water for 2030

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.

IEA SHC Task 70: Low Carbon, High Comfort Integrated Lighting

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.

IEA-SHC Task 64: Solar Process Heat

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.
