Jørn Toftum

Jørn Toftum is a Professor and Head of the Indoor Environment section at the Department of Environmental and Resource Engineering, Technical University of Denmark (DTU). His work is central to advancing knowledge in indoor environmental quality, human comfort, and sustainable building performance. He is actively involved in research, supervision, and international collaboration.

Research Interests: His expertise spans thermal comfort, indoor air quality, occupant behavior, energy efficiency in buildings, and human thermoregulation. He investigates how environmental factors affect human well-being and performance, particularly in office and residential buildings. His work integrates engineering, physiology, and behavioral science to optimize building design and operation.

Publication Trends: Recent publications (2025) emphasize advanced modeling of thermal responses, validation of thermoregulatory models (e.g., JOS-3), fault detection in building systems, and the impact of energy pricing on occupant behavior. These works reflect a strong trend toward data-driven, occupant-centric, and resilient building solutions aligned with sustainability goals.

Scientific Leadership:

• Head of Indoor Environment section, DTU
• Active supervisor of multiple PhD projects on occupant comfort, IoT, and energy use
• Member, EASAC Working Group on Decarbonisation of Buildings (2020–2021)

Advising and Grants: He supervises several PhD students and leads or participates in funded research projects, including those focused on personalized comfort, IoT-based data acquisition, and energy price impacts. His projects often involve interdisciplinary teams and practical applications in real buildings.

Labs and Teams: He leads the Indoor Environment research group at DTU, which focuses on experimental and computational studies of building environments. The team collaborates widely across Europe and contributes to large-scale initiatives in building physics and sustainability.
