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 UsersTCP Empowering all: Gender in policy and implementation for achieving transitions to sustainable energy (Working period 2022-2024)
Previous work in the Task suggests that countries with higher income levels pay little attention to inclusive energy (-technology) use and its implications. Therefore, this project focuses on obtaining more data on the gender aspects of energy users through a survey, developing guidelines on inclusive technology development, and communicating the overall research results with interested stakeholders.
IEA UsersTCP SLA 2.0: Inclusive and Community-Oriented Approaches to a Social License to Automate (Working period 2022-2024)
