Indoor Air Quality - Science and Practice

Decoupled ventilation strategies for enhanced IAQ – “Demand cooling” and “Demand ventilation” The concept of decoupling “ventilation air” from “supply air” is fast emerging as an ideal solution to combat the problems associated with poor indoor air quality (IAQ). This talk will present the Personalised Ventilation (PV) system and the Single Coil Twin Fan (SCTF) system, which show considerable promise in their abilities to provide both good IAQ and energy efficiency. The PV system is fundamentally aimed at improving ventilation in the immediate breathing zones of occupants in the built environment. The SCTF system is a new air-conditioning and air distribution system that improves occupants’ thermal comfort and indoor air quality whilst significantly saving energy. It provides “demand ventilation” and “demand cooling” by dynamically responding to the varying requirements in the individual occupied zones of a building. The current state of IAQ science and instrumenting technologies The health and wellbeing certification agenda has come to prominence in recent years, bringing with it the potential for a paradigm shift in how buildings are designed, constructed and operated. Proponents of these new certification schemes take comfort from the World Health Organisation (Martuzzi & Tickner, 2004) defined "precautionary principle" to justify probabilistic concerns, stating it is better to exercise preventative care responses about the health impacts of the multitude of known pollutants in indoor air. However, concerns are growing that health and wellbeing certification standards are developing in the absence of any real-time data collection or observed evidence of direct causal relationships between poor air and adverse health impacts.
