Replace or supplement mechanical ventilation with natural ventilation or mixed-mode conditioning to achieve 47-49% HVAC energy savings, 0.8-1.3% health cost savings, and 3-18% productivity gains, for an average ROI of at least 120%. Read more

This study copes with the problem of ventilation in existing educational environments in terms of indoor air quality (AIQ), comfort and energy consumption. In accordance with international regulations, densely occupied environments such as school classrooms need high air change rates in order to provide sufficient fresh air. Read more

The present investigation provides strong evidence that low ventilation rates in classrooms significantly reduce pupils’ attention and vigilance, and negatively affect memory and concentration. The physical environment therefore affects teaching and learning. Read more

Advanced design techniques today allow large buildings from different sectors to be naturally ventilated without the use of mechanical HVAC systems. Where natural ventilation was applied, a considerable saving opportunity was demonstrated, so why it is not widely adopted and why are mechanical systems still preferred? Read more

The adaptive comfort model provides a theoretically coherent option that opens up many cost-effective, low energy design alternatives. Numerous example applications are appearing all over the world. This paper describes Australian applications in mixed-mode buildings. Estimates of building energy conservation are 40% and 45% for the Sydney and Melbourne case-studies respectively, compared to the Australian conventional HVAC benchmark. Read more
