IEA EBC Annex 84: Demand Management of Buildings in Thermal Networks
The concept of demand-side management (DSM) in buildings to reduce peak loads in the grid is well established in the power sector. The same concept can be applied to shift thermal loads in buildings connected to thermal networks. This project addresses the topic of demand response in buildings, focusing on the collection of case studies, technologies and collaboration models.
Webinar: Indicators to Assess Resilience of Cooling in Buildings
10. May 2022
Online, AT
Well-insulated and air-tight buildings are known to be vulnerable to overheating. An increase in the severity and duration of heatwaves is expected, resulting in more severe overheating risks, affecting on their turn the health and mortality of building users. To achieve more future-proof buildings, it is crucial to design buildings that are "resilient" to overheating in future climate conditions.
IEA HPP Annex 33: Compact heat exchangers for heat pumping equipment
International cooperation aiming at widening the use of compact heat exchangers in heat pumping equipment. The goal of this project is to identify compact heat exchangers, either existing or under development, that may be applied in heat pumping equipment such as compression or absorption heat pumps.
