[SY03] MOCCIE2: MOdelling Consortium for the Chemistry of Indoor Environments 2
Organizer: Nicola Carslaw (University of York, UK)

This session will provide an overview of the MOdeling Consortium for Chemistry of Indoor Environments 2 program, MOCCIE2. MOCCIE2 is part of the Chemistry of Indoor Environments (CIE) program funded by the Alfred P. Sloan Foundation and involves eight groups, 7 based in the US and 1 in the UK. The session will comprise of presentations by 6 of the groups and will present the latest findings from this project to the wider community. This project builds on an earlier grant where we focused on ways to form links between the models from the 6 original groups in MOCCIE, with themes around cleaning and skin oil emissions. MOCCIE2 builds on these strong foundations with new topics such as emissions from cooking, surface film chemistry and insight from using models to investigate the recent HOMEChem Campaign in Austin, Texas.

[SY06] Advancing exposure assessment of air pollutants for environmental risk management
Organizer: Wonho Yang (Daegu Catholic University, Korea)

Exposure assessment remains a major weakness in Environmental Health Science. Due to the financial and logistical cost of personal monitoring, most epidemiologic studies have relied on surrogate estimates of exposure, usually assigned to the home location of study participants. The errors in these exposure assignments can bias attempts to assess the adverse health effects of environmental stressors toward the null. This session will provide a commentary on the impact that ubiquitous and participatory sensing will have on exposure assessment in Environmental Health. We will build on a developed framework and review novel developments in sensing that will lead to more precision in exposure assessment than has been possible in the past. Ubiquitous and participatory sensing offer tremendous promise for improved exposure assessment and increased confidence in the results of health effects assessments in Environmental Health research. Protection of personal privacy, analysis of the voluminous data generated by the sensors, and integration with other emerging methods from molecular epidemiology represent critical areas for research and development. The following subjects will be presented;

[SY07] Indoor Air Modelling and (Quantitative Microbial) Risk Assessment – What’s Missing and Where Do We Need to Go Next?
Organizer: Marco-Felipe King (University of Leeds, UK)

The field of indoor air modelling is in constant evolution, often with computational fluid dynamic predictions firmly a mainstay of infection risk modelling, however coupling with tangible and quantitative microbial risk assessment (QMRA) models is still tenuous. There is an imperious need for a mutual understanding between groups who model disease spread by linking infection with the air and subsequent surface contamination and those who use infection risk models in QMRA. We propose a symposium to attempt to join these together in the following way.
Aims are two-fold: 1) To assess the direction of techniques in both fields to identify novelty in airflow/surface contamination predictions with particular focus on risk and defining areas in need of validation 2) to engage in an interactive debate with the audience on what is the road to take for the future, in science and in industry with special emphasis on accuracy, level of detail required, and computational or experimental demand.

[SY08] Effect of indoor environment on work performance
Organizers: Zhiwei Lian (Shanghai Jiao Tong University, China)
Organizers: Shin-ichi Tanabe (Waseda University, Japan)

The indoor environments should enhance occupant’s health, comfort and productivity as people spend around 90% of their lives indoors. However, energy policy goals in many countries are often focused only on the implementation of measurable energy savings in buildings without taking into account the consequences for building users. This has been changed as some Energy Directive requires that the energy in buildings should be reduced without compromising the indoor environmental quality. Still, however, it is not clear yet the effects of indoor environment in terms of both health and decreases in productivity due to the lack of coherent approach. Therefore it is difficult to persuade clients to accept the concept of a relationship between indoor environmental quality and economic productivity benefits. How to assess the effects of indoor environmental quality on productivity remains to be the major challenge. This is that this proposal aims at.

[SY09] Challenges in ventilation for the operating theatres of the future (modelling, sensing & control): Making the invisible visible
Organizers: Guangyu Cao (Norwegian University of Science & Technology, Norway)
Organizers: Amirul Khan (University of Leeds, UK)

Ventilation and airflow are crucial in operating rooms (OR) for controlling thermo-hygrometric conditions, providing gas removal, dilution of airborne contaminants and minimising the airborne transfer of pathogens (bacteria). In order to maintain a safe and comfortable environment for patients and staff all of these considerations must be met, and each of them has specific requirements. Therefore, for these requirements to be met efficiently, design engineers and operators must rely on various analysis (computational, analytical) and control methods (model-based) that provide the most reliable and detailed information as possible. In this symposium we aim to bring together experts with complementary expertise in the field of indoor environment modelling (computational fluid dynamics), sensing and control applied to the operating-theatre environment. The symposium will enable cross-disciplinary interaction and group thinking to address some of the challenges of the OR of the future by reviewing existing approaches and proposing new methods. The chosen presentations will enable researchers to engage with various complementary topics providing (1) with improved understanding of the local influence of airflows on particles close to occupants, (2) improved quantification of the transient behaviour of the OR indoor environment (ORIE) including the fate of contaminants due to healthcare activities, (3) introduce to the methods of augmenting computer simulation with measured sensor data to enable a deeper understanding of the ORIE and thereby paving the way for a robust, adaptive and energy-efficient ventilation control system for the OR.

[SY10] Kitchen Ventilation Requirements for High Performance Homes
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.

[SY11] Understanding of IEQ Factor Interactions-Current Status and Research Needs
Organizer: Bjarne W. Olesen (IEQ-GA (Indoor Environmental Quality-Global Alliance) / DTU, Denmark)

In the design and energy performance prediction of buildings and HVAC systems, it is important to use established requirements for Indoor Environmental Quality parameters. The indoor environmental factors are Thermal Comfort, Indoor Air Quality (IAQ, ventilation), Lighting and Acoustic.
Two international standards (ISO 17772 and EN 16798-1) deal with requirements for all four indoor environmental factors. The requirements, however, do not take into account any interactions between the parameters.
ASHRAE Guideline 10 “Interactions Affecting the Achievement of Acceptable Indoor Environments” does give some guidance related to such interactions, although, studies to date of interactions between Thermal, Visual, Aural and Olfactory influences on perception are not conclusive. Knowledge of the relative importance of the four factors on the dissatisfaction of people is very limited and there is a need for further research.
This symposium will focus on the existing state knowledge regarding interactions, primarily as they affect perception of indoor environmental quality and will give examples of interactions between all four indoor environmental parameters. Knowledge gaps and research needs will be discussed.

[SY12] IEA-EBC Annex 78: Substituting Ventilation by Gas Phase Air Cleaning
Organizer: Bjarne W. Olesen (Intl. Centre for Indoor Environment and Energy, Technical University of Denmark, Denmark)

Worldwide, there is an increasing number of publications related to air cleaning and there is an increasing sale of gas phase air cleaning products. This puts a demand for verifying the influence of using air cleaning on indoor air quality, comfort, well-being and health. It is thus important to learn whether air cleaning can supplement ventilation with respect to improving air quality i.e. whether it can partly substitute the ventilation rates required by standards. There is also a need to evaluate the energy impact of using air cleaning as supplement to ventilation.
In many locations in the world, the outdoor air quality is so bad that it is better to avoid supplying outdoor air to the buildings. In such cases, the alternative to use ventilation is to substitute supply of outdoor air with air cleaning. Even when outdoor air is of a good quality, the use of air cleaning substituting ventilation air could reduce the rate of outdoor air supplied indoors. Therefore, it is possible to save energy for pre-heating/cooling the ventilation air and for transporting the air (fan energy).
To verify the performance of gas phase air cleaning technologies there is a need to develop appropriate standard test methods.
This is some of the issues that is part of a new IEA-EBC Annex 78 and which will be covered by presentations and discussion in this session.

[SY13] Occupant-centric building design and operation
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.
