Performance-based IAQ regulations in dwellings: present and future.

DESCRIPTION OF THE SESSION

The main objective of the topical session is to highlight the importance of performance-based regulations to achieve adequate IAQ in line with advanced energy efficiency requirements.

Performance-based regulations enable high quality standards by characterising and quantifying the required performance of buildings. These performances can be met in a flexible way with different solutions, thus allowing for innovation. In contrast, prescriptive regulations impose fixed solutions in order to comply with the necessary requirements, which can be a barrier to innovation. Furthermore, performance-based regulations allow requirements to be met in a more optimised and tailored way adapted to the particular conditions of each case.

Regarding IAQ requirements, performance-based regulations promote the use of smart ventilation systems, which facilitates the desired balance between IAQ and energy efficiency.

The topical session will provide an update on the state of the art of IAQ regulations in dwellings. It will review the most advanced performance-based regulations in Spain and France, and highlight obstacles and difficulties in their implementation, such as their use in naturally ventilated dwellings. Additionally, an IAQ estimation model for naturally ventilated dwellings will be presented to help overcome this issue. Finally, potential future changes to the performance-based IAQ regulations will be discussed, including new challenges such as the consideration of harm to people.

OBJECTIVES OF THE SESSION

  • To highlight the importance of performance-based regulations to achieve adequate IAQ in line with advanced energy efficiency requirements.
  • To update the state of the art of IAQ regulations in dwellings, highlighting obstacles and difficulties in their application.
  • To present an IAQ estimation model for naturally ventilated dwellings.
  • To discuss potential future changes in performance-based IAQ regulation.

Prof. Sani Dimitroulopoulou (UK Health Security Agency, UKHSA)

Sani is a Principal Environmental Public Health Scientist, Air Quality and Public Health, UKHSA (formerly Public Health England, PHE) leading on indoor air quality and health.
She is also Visiting Professor, at Institute for Environmental Design and Engineering, The Bartlett School of Environment, Energy and Resources, UCL.
 
Her research interests include exposure assessment to air pollution, based on modelling and monitoring of outdoor and indoor air pollution and ventilation, health impact assessments and development of environmental public health indicators and indoor air quality guidelines.
She works closely with colleagues from UK Government Departments (e.g. DHSC, DfE, DLUHC, Defra, DESNZ) and Organisations (e.g. WHO, NICE, CIBSE, RCP/RCPCH, BSI) to provide expert advice on indoor air quality and health. She participated in the Cross Whitehall Group for the revision of the Building Regulations, Part F and she sits on the Advisory Board organised by DLUHC for the revision of HHSRS (Housing Health and Safety Rating System). She was the UKHSA project manager for the development of the DHSC/UKHSA/DLUHC guidance on “Damp and mould: understanding and addressing the health risks for rented housing providers”. She is the Chair of UK Indoor Environments Group (UKIEG).

Dr. Ana Maria Scutaru

Ana Maria Scutaru is a scientist at the German Environment Agency (UBA) in Berlin. She received her PhD in Pharmaceutical Chemistry from the Institute of Pharmacy at the Freie Universität Berlin in 2011. Her work focuses on the health-related evaluation of building products emissions into indoor air and other indoor air related topics. Ana Maria Scutaru is the secretary of the Committee for Health-related Evaluation of Building Products (AgBB) and of the EU-LCI Working Group within the harmonisation framework for health-based evaluation of indoor emissions from construction products in the European Union.

Corinne Mandin earned her PhD in environmental chemistry from the University of Rennes, France.
She has been working on human exposure to chemical substances and physical agents and the related health effects, first at INERIS (French national institute for industrial environment and risks) for 8 years, and then at CSTB (French scientific and technical center for building) for 13 years. At CSTB, she coordinated the French Indoor Air Quality Observatory, a public research program created in 2001 to carry out nationwide surveys on air quality in buildings. In 2022, she joined the French institute for radiation protection and nuclear safety (IRSN) where she leads the radiation epidemiology group.
She has been involved in various European and international projects and expert committees, including at the World Health Organization and the European Joint Research Center. She is currently chairing the expert committee dedicated to outdoor and indoor air quality at the French Agency for Food, Environmental and Occupational Health and Safety (Anses). She was president of the International Society for Indoor Air Quality and Climate (ISIAQ) from 2020 to 2022. In 2022, she coedited the Handbook of Indoor Air Quality (Springer).
