Understanding occupant expectation and feedback is an important part of building performance evaluation. This paper explores occupant satisfaction change during a 10-year period in a green building located in the subtropical zone. Occupant satisfaction at two timestamps, three and ten years after project completion, were compared. It was observed that occupant satisfaction regarding indoor air quality (IAQ), noise and overall building comfort remained unchanged during the 10-year post-occupancy period. This finding suggests that perceived IAQ, noise, and overall satisfaction with buildings may not be biased by point-in-time of surveys, the year weather or sample characteristics. However, satisfaction scores regarding the two parameters of lighting and thermal comfort are likely to be subject to change over time. The change in satisfaction scores in relation to thermal comfort and lighting might be explained in various ways. The change of climate and sky conditions, and different sample characteristics were the two assumptions considered worthy of further investigations. The study found some evidence of a possible correlation between year weather and occupant satisfaction responses. The study also showed that green buildings with natural ventilation may be more susceptible to climate change impacts.

|Other||The conference theme of the 52nd International Conference of the Architectural Science Association on Engaging Architectural Science: Meeting the Challenges of Higher Density, emphasises the issue of built environments for growingcities. What is the outlook on urban futures and densification? Cities have been viewed as sustainability problems rather than solutions. As concerns about urban sprawl, densification, shanty towns and climate change grew, so did the awareness for high-performance, energy-efficient building and walkable neighbourhoods make cities liveable and offer far greater benefits for the global environment. For example, high-density living has been viewed as a key strategy to manage urban growth and is increasingly becoming a feature in city planning. By 2030, 60 percent of the world’s population will live in cities (McKinsey & Company, 2013). Australian cities have seen a rapid increase of high-rise residential construction which generates, among others, a discussion on planning controls in inner cities.|
