REHVA is hosting technical workshops at CLIMA 2025 to advance and share the most reliable knowledge in the HVAC field. To achieve this, REHVA is collaborating with a diverse range of partners:
REHVA workshops with international partners
REHVA - ISHRAE: Indoor climate targets and design requirements in Indian and European education buildings
4th June 14:00 - 15:30
Poor indoor air quality in schools is a growing concern, with inadequate ventilation, exposure to outdoor pollutants, and thermal discomfort affecting students' well-being and performance. While energy efficiency in buildings has been prioritized in recent years, it has sometimes come at the cost of indoor environmental quality.
This workshop will explore the challenges of balancing energy efficiency with a healthy indoor climate in educational buildings. Participants will discuss strategies to improve IAQ, thermal comfort, and overall environmental conditions while maintaining sustainable energy use.
REHVA - CAHVAC: Healthy Sustainable Buildings in Europe and China
5th June 14:00 - 15:30
This workshop explores the integration of innovative HVAC technologies and sustainable building solutions, drawing from collaborative research by REHVA and CAHVAC. Presentations will address emerging challenges in energy efficiency, indoor environmental quality, and the health impacts of building designs.
Discussions will focus on multidisciplinary approaches and cutting-edge methodologies for optimizing HVAC systems. Experts will present insights into advanced energy performance assessments, case studies, and strategies to enhance both sustainability and occupant well-being. The session aims to foster knowledge exchange and collaboration among researchers, practitioners, and policymakers.
REHVA - SHASE: Introduction of Joint position document by REHVA (EU) and SHASE (Japan) and ZEB case studies
4th June 16:00 - 17:30
This workshop presents findings from a joint study by SHASE and REHVA on the definitions and calculation methods for Zero Energy and Zero Emission Buildings. Experts will discuss the latest updates following the 2024 EPBD revision and Japan's ZEB framework.
Key topics include energy performance assessments, results from model energy simulations in three European climates for ZEB apartments, and evaluations of office buildings in Japan. Additionally, the workshop will explore HVAC system comparisons, analyzing thermal comfort, air quality, and energy performance to determine the most efficient solutions for ZEBs.
REHVA workshop on IEQ in EPBD, by REHVA TRC
5th June 10:15 - 11:45
Long term assessment by simulation or monitoring, labels and regulation
The 2024 recast of the Energy Performance of Buildings Directive introduces significant new requirements for indoor environmental quality, setting a new standard for national regulations. This workshop will explore key changes, including the principle of optimal IEQ, the establishment of national IEQ requirements, and the mandatory integration of indoor air quality monitoring and regulation devices in new non-residential buildings.
Discussions will focus on the growing need for demand-controlled ventilation systems, which will become essential from 2028/2030, and the challenges of ensuring their long-term performance. With continuous monitoring generating vast amounts of data, we will examine tools and methodologies for assessing IAQ and thermal comfort, optimizing system operation, and improving occupant well-being.
