IEA HPT Annex 63 - Placement Impact on Heat Pump Acoustics - Overview and Austrias Contribution to the Network

IEA HPT Annex 63 builds on Annex 51 to address the growing impact of acoustic issues on heat pump deployment. While Annex 51 laid the groundwork, Annex 63 focuses on the influence of placement, aiming to reduce noise-related market barriers. It expands to include cooling mode acoustics, psychoacoustics, and specific use cases such as urban and building environments. Each installation scenario is unique, highlighting the need for revised guidelines and digitally supported placement tools. Annex 63 fosters international collaboration, standardizes data, and supports the continued growth of heat pumps as a leading renewable and energy-efficient HVAC solution. This contribution gives an overview of the activities within IEA HPT Annex 63 especially focussing on Austrias contribution within the network.
