He chaired the 2008 ANZSES/ISES Asia Pacific Conference on Solar Energy, 2001 ISES Solar World Congress (Co-chair - Adelaide) having chaired the 2004 ANZSES Annual Conference and numerous similar events.  In 2009 Deo was one of two Australians (of a total of 18) named as ‘champions for green developments’ in Asia Pacific by the highly regarded Singapore based journal ‘FuturArc’ (published by BCI Asia).  In 2009 Deo has also been named as a Sydney Ambassador by the NSW Government for promoting Sydney as a destination for high end scientific events.

Professor Deo Prasad has made substantial contributions to the field of green buildings research in Australia and overseas,  Deo's key contributions are in the area of sustainable buildings, its key indicators and synthesising these into either assessment tools or building design. Deo has conducted numerous case studies of all building types for their sustainability credentials (published by the Australian Council for Building Design Professions - EDGe Notes; 1995-2006). Prasad has recently supervised four doctoral investigations in the field of assessment and monitoring tools for sustainable buildings and cities. These researchers have uncovered some fundamental problems and opportunities in environmental monitoring such as risk and uncertainty, the need for GIS linked methodology and two of the projects have looked at applying such methods in China and India. Additional two doctoral students of his are investigating indoor environmental quality and performance in green and non-green buildings in Singapore and Seoul. One of his doctoral students recently completed her thesis on benchmarking indoor air quality in buildings in Japan. Deo has recently completed a collaborative project with researchers from the University of Queensland developing standards and indicators for sustainable tourism development. Project outcomes including an assessment and monitoring system and related benchmarks and methodologies for incorporating indoor air quality as an indicator in the framework. The work is for Green Globe Asia-Pacific, an Australian company, which certifies tourism developments for their sustainability. It requires ongoing assessment and certification.  Deo is a consultant on two current projects in Singapore (funded by Singapore Government/BCA) through the National University of Singapore (NUS):

• Post occupancy evaluation of Greenmark Assessment System for green buildings in Singapore

• Building integrated photovoltaics (this project included the recently launched Zero Energy Office building for BCA).
