Living in Singapore during October brought the Idea of air quality into sharp relief. As winds drove smoke from plantation burning in Indonesia over the city, the skyline was shrouded in a dirty haze and the country's pollution standards index ( PSI) numbers skyrocketed into the " unhealthy '' range. Establishing good indoor air quality means controlling the innumerrable potential pollutant sources both outside and indoors while ventilating and conditioning the space, ideally in an energy - efficient manner.Adding to the complexity is the spectre of infectious diseases spreading through ventilation systems - a possible contributing factor behind the severe acute respiratory syndrome ( SARC) outbreak in Hong Kong.Still FuturArc highlights some projects that show how it can be done : Australia ' s Green building rating system has introduced an Office Interiors rating, raising awareness of the importance of good indoor air and the Seattle Housing Authority in the US has built homes targeted at preventing childhood asthma attacks. Healthier air means healthier people. And to further celebrate the idea of healthy living, FuturArc looks at sports projects. With the Beijing 2008 Olympic Games just around the Corner, this edition runs a special section on Olympic venues, including a tour of the capital' s new projects. But the Olympic aren ' t the only thing going on in sports in the Asia - Pacific region. Other excicing development are happening in China, Southeast Asia and Australia, and here, FuturArc presents their profiles. In this, our fourth edition, we announce the BCI Asia Top 10 Awards 2007, acknowledging those architecture firms with the greatest influence on the buil environment in Southeast Asia and China. The Top 10 Awards mark the end of FuturArc' s first year of publishing - we hope you have enjoyed it as much as we have.
