Ventilative Cooling – latest and greatest. Importance of early design in the world of overheating mitigation using ventilative cooling

DESCRIPTION OF THE SESSION

Join us for an insightful session as we delve into the latest breakthroughs for overheating mitigation using ventilative cooling and cutting-edge findings from new projects. In this dynamic session, experts from various disciplines will converge to explore the impact, applications, and advancements in how to design ventilative cooling systems in upcoming standards, while also leaving good time for discussions in the latter part of the session.

The purpose of this session is to:

  1. Give an overview of how ventilative cooling fits in the standardisation world. What are the gaps and how can it fit in future European standards.
  2. Give examples on how to apply the design route in the upcoming ventilative cooling standard for your next project. We will go through the various design steps in the standard and explain the rationale behind these. These should secure a robust and resilient VC design.
  3. Highlight the differences between the theoretical predictions using the VC potential method/tool versus data from a case study. This will enlighten the participants and make them aware of the potential of the method, and more importantly, become aware of its limitations.
  4. Have an interactive discussion on the design paths to secure an optimal VC design and receive input from the audience on subjects to be included in these design paths.

OBJECTIVES OF THE SESSION

The objective of this session is to provide participants with a comprehensive understanding of the latest developments in ventilative cooling evolutions, while also having time to contemplate on relevant questions.

At the session we wish to further highlight the “hidden” features of how to actually design and calculate on overheating mitigation using ventilative cooling. Not all are aware that there exists good upcoming standards and tools that can highlight the potential of ventilative cooling in the early design stage. Hence, the main purpose is to explain a variable way to design a VC system including a feasibility path including a newly developed “VC potential method/tool”. This VC method offers a quick evaluation of the VC potential for the specific building location. To fully understand the VC method a case study will be provided to give an insight in the difference between the predicted values using the method versus the measured in the case study. 

Lastly, we want to include the audience in an interactive way by having a discussion on “how to ensure a good and resilient VC system design” and the findings should be included the current VC design path in this work. 

Therefore, we wish to:

  • Present the latest standardization projects on ventilative cooling and expected outcomes and how it fits in the future European standardisation.
  • Go through the VC design steps on how to design a proper ventilative cooling system including a case study example.
  • Facilitate a discussion to get the feedback on the VC design steps and what is missing or who to optimise the path.

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).
