14-15 March 2017, Workshop, Brussels - Is ventilation the answer to indoor air quality control in buildings? Do we need performance-based approaches?
Brussels, Belgium 03/14/2017 - 09:15

Indoor exposure to contaminants should be minimized to avoid adverse health and comfort effects. Experience shows that this qualitative statement is difficult to translate into measurable terms, such as performance indicators or metrics, which can be used as a basis for defining and assessing requirements in regulations and standards while holistically reflecting indoor air quality.

Indoor exposure to contaminants should be minimized to avoid adverse health and comfort effects. Experience shows that this qualitative statement is difficult to translate into measurable terms, such as performance indicators or metrics, which can be used as a basis for defining and assessing requirements in regulations and standards while holistically reflecting indoor air quality. The simplest and most commonly used approaches rely on ventilation airflow rates determined by experts or codes. These approaches have fundamental shortcomings in practice for systems that do not have steady contaminant sources or do not provide a constant airflow rate, such as natural, hybrid, or demand-controlled ventilation. More sophisticated approaches can be based on health damage, pollutant exposures, or perceived air quality but they generally entail a number of assumptions about the pollutants of concern and occupant scenarios. Such methods could lead to useful metrics. However, as of today, there is no clear set of metrics that can be used to assess the overall ventilation performance of a building with regard to its indoor air quality, or used in standards or regulations.


This workshop aims to identify the pros and cons of performance-based approaches and metrics that can be considered to assess the IAQ performance of ventilation systems, as well as to draft guidelines for their use in standards and regulations.


The workshop addresses IAQ performance for all building types and ages, with all types of ventilation system (natural, mechanical, hybrid systems). It does not cover the relevance of the associated metrics in terms of health, comfort or building damage, but looks at their relevance for comparing system performance or strategies in terms of IAQ. It focusses on performance-based approaches, such as those that focus on the performance to achieve rather than on the techniques or systems to be implemented.


The attendees at this workshop are expected to participate, either through presentation, or in active discussions during each session. Target attendees are experts, professionals, or scientists researching ventilation or IAQ issues related to existing or potentially new IAQ performance approaches, such as metrics.


AIVC will produce a summary of the workshop on the advantages and disadvantages of performance-based approaches discussed by the workshop attendees. It will be accessible to both industry professionals and advanced practitioners.


About one third of each session will be dedicated to discussions with the audience based on presentations, sometimes with the help of an interactive voting system to instantaneously collect the opinion of the attendees.


Keynote presentations will focus on the specifications and needs for performance-based approaches and associated IAQ metrics for building ventilation, which consider pollutants and sources of concern. The regular session presentations will review IAQ indices, analyze their pros and cons, and suggest improvements where necessary.


Topics addressed in presentations and discussions


  • Factors that should influence IAQ assessment

  • Is CO2 indoor pollutant?

  • The potential for, and limits of, CO2 based indices, humidity or moisture, health damage, perceived air quality, air mixing behaviour, and pollutant distribution within a space

  • The potential for, and limits of, combined indices

  • Definition and use of rating methods for smart ventilation, DCVs, natural ventilation, etc. (equivalent ventilation principle)

  • Barriers to performance-based standards (showing evidence of compliance, accounting for sources, sensors and controls, time-activity patterns)
