[SY13] Occupant-centric building design and operation

Date / Time November 2 (Mon), 12:30-14:10 (KST / UTC +9)
Organizer Andreas Wagner (Karlsruhe Institute of Technology, Germany)
Numerous studies identified the strong influence of occupants on building performance. This is exactly the focus of IEA EBC Annex 79, which intends to implement occupant behavior into the design process and building operation to improve both energy performance and occupant comfort. The main objectives of the Annex are:
developing new knowledge about adaptive occupant actions driven by multiple indoor environmental parameters;
understanding interactions between occupants and building systems in terms of comfort and building energy use;
deploying ‘big data’ for the building sector based on various sources of building and occupant data as well as sensing technologies;
developing methods and guidelines as well as giving advice for standards integrating occupant models in building design and operation;
performing focused case studies to test the new methods and models in different design and operation phases.
The symposium will introduce into the different fields of research of the Annex.

[WS14] Estimating and Comparing the Burden of Disease of Indoor Air Pollution worldwide

Date / Time November 2 (Mon), 14:10-15:50(KST / UTC +9)
Organizers Yinping ZHANG (Tsinghua University, China), Corinne MANDIN (Scientific and Technical Center for Building, France)
Background: Indoor air pollution has been neglected compared to ambient outdoor pollution while people spend over 80% of their time indoors. One reason may be that insufficient burden of disease data have been generated for indoor air pollution internationally and have reached the political and social spheres.
Scientific Purpose: Global estimates of burden of disease from indoor air pollution are now necessary, and to this purpose, harmonized methods must be set. To address this problem co-operatively, researchers are invited to constitute a panel.
Content of the session: Following the presentations of some evaluations of the burden of disease of indoor air pollution in China, Europe and the USA, the participants will be invited to discuss about the harmonized methods to be used, the existing data, the way to tackle the limitations, and the ways to convince policy makers.
This workshop will be the official start of a new Scientific and Technical Committee (STC) of ISIAQ targeted to the burden of disease of indoor air pollution.

[WS02] Sloan Workshop on indoor acid-base chemistry: findings and implications of an Indoor Air Major Review
(Sponsored by the Alfred P. Sloan Foundation)

Date / Time November 3 (Tue), 07:20-09:00 (KST / UTC +9)
Organizer Yuguo Li (The University of Hong Kong, Hong Kong, China)
This special workshop is based on the first Invited Major Review of Indoor Air Journal (Nazaroff and Weschler, Indoor Air, https://doi.org/10.1111/ina.12670), which is a thorough examination of acids and bases in indoor environments. The review establishes a foundation for future research to better understand indoor acid-base chemistry and its implications for human health, indoor air quality, and materials damage. Indoor environments contain numerous acidic and basic species. However, up till now there has not been a systematic review of the state-of-knowledge for this important topic that broadly impacts indoor environments.
In this wokshop, we will discuss sources, concentrations, fates, and dynamic behavior of acids and bases in occupied buildings. The session will begin with presentations by the authors of the review (Prof. William W Nazaroff and Prof. Charles J. Weschler), followed by discussion with a panel that consists of chemists and building scientists. The panel and participants will identify the future research directions and opportunities for collaboration within the indoor air research community.

[WS01] Sloan Workshop on transmission of SARS-CoV-2 and environmental intervention in indoor environment
(Sponsored by the Alfred P. Sloan Foundation)

Date / Time November 3 (Tue), 10:20-12:00 (KST / UTC +9)
Organizer Yuguo Li (The University of Hong Kong, Hong Kong, China)
Debate continues on the transmission routes of SARS-CoV-2, the virus that causes COVID-19, in the rapidly growing COVID-19 pandemic, however, there is no doubt that most infection so far has occurred indoors. This pandemic has occurred in the new age of big data, AI and 5G communication. This has provided an opportunity to explore the dynamics of infection and transmission as affected by indoor environment, i.e. hospitals, homes, offices, shopping centres, train and plane cabins, restaurants, subway stations where people live, work and socialize.
In this workshop we will discuss the latest findings in our global inquiry of the transmission routes and intervention in buildings, including impact of indoor environment in major outbreaks, mathematical and statistical modelling of effects of indoor environment including human behavior, intervention methods related to indoor environment, behavior and properties of bio-aerosols containing the virus in buildings, etc. The panel and participants will identify the future research directions and opportunities for collaboration within and beyond the indoor air research community.

[SY10] Kitchen Ventilation Requirements for High Performance Homes

Date / Time November 3 (Tue), 12:30-14:10 (KST / UTC +9)
Organizer Brett C. Singer (Lawrence Berkeley National Laboratory, USA)
Air pollutants emitted by cooking burners and produced by many cooking activities can reach levels in homes that exceed health hazard guidelines and standards. Excess moisture from cooking and burners can contribute to dampness and mold problems. As awareness of these hazards grows, there is increasing attention to the importance of effective kitchen ventilation to reduce exposures and risk. Existing codes and standards – such as the requirements of the ASHRAE 62.2 ventilation standard – may not provide sufficient protection based on non-use or low capture efficiency. And as homes become tighter for energy efficiency, new performance standards and tests will be needed. This symposium will bring together research and development efforts in the US and China to identify suitable performance requirements and test methods for next generation kitchen ventilation.

[WS12] Human-Building Integration as an Innovative Principle to Control Indoor Environmental Quality

Date / Time November 3 (Tue), 14:10-15:50 (KST / UTC +9)
Organizer Joon-Ho Choi (University of Southern California, Los Angeles, California, USA)
Due to advances in today’s sensing and mobile technologies, more and more data can be easily and effectively collected by various means. It is now feasible to collect and process a large amount of real data about the environmental satisfaction levels of a building’s occupants. A human body naturally reacts to ambient environmental conditions to minimize any environmental stress based on its autonomic nervous system (Streeten 2014). Therefore, the goal of this proposed workshop is to enhance the interdisciplinary knowledge to advance building indoor environmental controls as a function of human bio-signals (i.e., physiological signals). To identify intellectual challenges and research gaps, the following research components will be discussed with the four invited experts, internationally well-known in the IEQ/Human-Building-Interaction domains:
1) Human factors/bio-signal-types that can be integrated with building IEQ control and system/architectural design processes.
2) Relationship between human physiological signals and IEQ components, such as thermal, lighting, air, acoustic, and spatial quality conditions.
3) Exploitation of advanced hardware and software technologies that are capable of integrating building indoor environmental quality control and design with human factors as a sustainable environmental control strategy.

[WS06] Indoor Chemical Human Emissions and Reactivity (ICHEAR)
(Sponsored by the Alfred P. Sloan Foundation)

Date / Time November 4 (Wed), 09:50-12:00 (KST / UTC +9)
Organizer Jonathan Williams (Max Planck Institute for Chemistry, Germany)
With increasing use of low-polluting building materials and furnishings, and construction of energy efficient airtight buildings, emissions from humans are likely to grow in importance. Emissions via breath and skin represent mobile, potent, chemically diverse and highly variable sources of reactive chemicals in indoor spaces. ICHEAR aims to comprehensively characterize the chemical impact of human beings, the single common element in all living spaces. The aim of the program, sponsored by the A.P. Sloan Foundation, is to utilize state-of-the-art measurement techniques to examine the role of humans and their emissions in indoor air chemistry. It investigates the impact of exhaled and dermally emitted human bioeffluents under different conditions comprising human factors (level of clothing, age) and a variety of environmental factors (temperature, relative humidity, ozone). The symposium will, in a series of presentations, summarize the first findings, some of them being first of their kind. First, a comprehensive summary of the climate chamber experiments with human subjects will be presented. This will be followed by presentations on human CO2 emissions, human ammonia emissions, human VOC emissions and their transformations, impact of occupant-initiated chemistry on single-digit nanometer size particle concentrations, bioaerosols, skin surface chemistry and total OH reactivity.

[WS13] Global studies on indoor environment and health, a journey from dampness to chemicals

Date / Time November 4 (Wed), 12:30-14:10 (KST / UTC +9)
Organizer Yuexia Sun (Tianjin University, China)
Asthma and allergies have increased dramatically all over the world, and especially among children. However, there has been little scientific focus on the exposure of small children (and possibly fetuses), indoors, especially in homes. Since the first study was conducted in Sweden 2000 (DBH), the same study has then been repeated in Bulgaria, Singapore, Taiwan, Denmark, USA, South Korea and China. The questionnaire is about children’s health (asthma, allergies, airways infections), the families’ health, and the home environment. In the second step case-control studies with measurements and inspections have so far been carried out in Sweden, Bulgaria, Singapore, Taiwan, Denmark and China. The baseline questionnaire is then followed up for a longitudinal design, so far conducted in Sweden (SELMA) and China, with extended aims of investigating risks of indoor chemicals (EDCs such as phthalate, bisphonals, PFAs, flame retardants, etc.) on children’s health (e.g., neuro and sexual development).
This workshop will give a world view of indoor environment (housing) and health among children. The main findings from separate studies will be summarized and updated. Similar and different risk factors in the indoor environment affecting children’s health will be identified.
This workshop is a contribution from ISIAQ STC31 “Health Effects and Epidemiology”.
